I bought a Kit from Brian and I had a little bit trouble with it. He replied to my comment, gave me his number, then talked me through some issues and sent my a free bottle and a replace part. What a great company!
I'm here to help, glad I could 😀
I’m gonna try the fix today fingers crossed 🤞🏽
Purchased: August 2023 - still works GREAT!I th-cam.com/users/postUgkxxsUnXhGsSJLim_XnMHyQK0u3XVaW-CGn live in a studio and during the summer it gets scorching hot - really old building with no ac units. I can’t express how EASY it was to install. This unit has been a life savior during the summer and some days during other seasons where it can still be a bit warm at night. In this small place is my friend, a husky, poodle mix and myself. We need AC - lolI don’t use the dehumidifier option - I’m not sure if it will leak in my house, since I did not install the small draining hose that came with it. May look into it late but I don’t worry about much humidity in the apartment. I don’t understand why the negative reviews since all things mentioned, I personally did not find issues with. Definitely worth it!
Thank you for sharing 😀
Young communication & video is outstanding. Thank you 👍🤠
Thank you for Watching!
Caught comment at end of clip about; ... Make sure you are in AC mode when recharging. Would like to see more specifics on prep before recharge.
I have detailed instructions included in each kit, but you want the system On and in Cooling mode 62 degrees while recharging.
Update - I would like to thank you again for this info. I'm happy to say I used one of these kits to recharge the my fourth unit. So this fix works!
Now I'm going to recharge unit another unit that stopped heating. After owning 4 of these units bought between 2021 and 2022. I'm convinced that they're going to need yearly charging. I've had to recharge all units during the summer for Collings and now I'm going to do my 2nd unit for not heating. Hopefully that is the worst of these but I am not holding my breath.I have a 5th cabin that's going to get a mini split and it will NOT be a MrCool.
Anyway, I appreciate the fix. Thanks.
Thank you for the update, the sealant I have in the kits will either stop or significantly slow any leak you may have!
BTW, I clicked on the link and it's not working. I wanted to buy a refill of the R134 refrigerant. You should look into it. FYI. @@GarageMahalLife
One more thing, the fix worked again on the aforementioned unit.
Thanks for your video. Just ordered a kit! I hope it works!! I have a Fujitsu 18,000 btu Halcyon. It was installed new in 2019 and I'm pretty sure there is just a leak somewhere in the line .
Thank you, this should fix you right up 😀
This could be a good kit. I am wondering if it will work in the long run. It seems like this kit would introduce a slug of air into the refrigerant cycle without purging the supply hose set up. Is there a purging technique? Also You have to find the leak before putting more refrigerant in. Tightening the fittings doesn't usually fix leaks. Often they are already over tightened and will leak faster with more torque. Just my experiences.
It's a Great kit! If you are familiar with purging, feel free. However with such a small amount of air, it is compensated with a drying element in the formula that produces the UV dye and sealant, so not a 100% necessary. I made it to be simple and nothing complicated. Although over tight or too loose can affect leaks, I'd rather have it a but tighter than looser. Thus the other reason for the sealant. It will fix leaks on almost any leaks, keeping I. Mind the system originally was working as it should in the beginning. Anyway thank you for watching and hope I answered any question you had. Thanks for the comment and be safe out there!
Why was it low, adding refrigerant to a leaking unit without repairing the leak is nor repairing the problem.
Thus why my kits have a sealant that fixes most leaks! 😉
@@GarageMahalLife thus.
Why are you adding refrigerant for a heating problem?
@@mtkoslowski you obviously know nothing about how heat pumps work. Take a seat. More learning, less talking.
Do you cut the power when doing this?
I ordered the kit after seeing your TH-cam clip. It arrived quickly and the instructions are great.
The reason I ordered it was because my Mr. Cool self-installed system abruptly stopped heating about a week ago.
The outside unit (compressor) will now turn on when I set it to heat mode, whereas it didn't before. However, it’s still not putting out heat. The blower on the inside unit will turn on if I switch to Cool mode. But if I switch to Heat mode it stops blowing no matter what I set the fan at.
The filters and outside unit are clean too. The only factor I can think of right now is the outside temperature. Since this problem started, it has been unseasonably cool where I am in California in January. It usually doesn't go below 40 and highs are normally around 50-60. However it's been close to 30 and highs below 50.
Could it be a bad temperature sensor instead?
Great description on what's going on. Recharge in cooling mode, despite the temp. Get it closer to the end of the right of the blue on the gauge. Remove charge hose and put back into heat mode. Put it to 86 degrees, leave for an hour. Check outside line to make sure 1 is at least 140 degrees, the other should be cold. Make sure the filters are clean and the find the inside temp gauge. Which is a small clear tube on the right side of the inside unit. Cup your hand over it and use a vacuum to suck all the dust out of that line.
I just ordered a kit after seeing our video. I have 4 of these DIY mini splits and I've had to charge every one for bad cooling after one summer. Now, the newest of the bunch is not heating properly. I regret buying MrCool units but in reality, I needed 4 units and these I could afford. 4 of the better units would have put me over on costs. It is what it is. I gotta make these work one way or another.
They are great units vs. Cost of a HVAC install for sure. All units will have their flaws, I'm here to help fix those flaws 😀 my kits will help fix you right up!
Ours don’t seem to be putting out the heat we just got this unit last year first year using the heat
In cooling mode, does it operate okay? But typically a low refrigerant issue... That new I would contact MRCool, but you can get one of my kits and it should fix you right up.
I have a 18k diy unit that we installed little over a year ago. Been working great until a couple months ago when we needed to use the heat again. Keeps popping a p4 code and just the fan will run. Now the cooling does the same thing as well. The outside unit wont kick on at all, the voltage is good but not sure about the refrigerant... tried calling mr cool but cant get a hold of anyone... about to have our first baby so really want this fixed before she gets here😢
My kit will fix you right up and get that little one warm 😀
Brian my 24 k replacement condenser came in today and I know I asked you this once but want to be sure.
I know the new lines are charged but what about the 3 foot coming out of the indoor unit. When I undo these lines from the old lines will I have air in them? Do I need to do anything to prevent this or is it not enough to affect the unit? Thanks again.
Rick
Rick, send me an email brian.niskala@cnjrail.com
Hey Brian, thanks for doing the video. I awoke this morning to my Mr cool unit blowing cold air in heat mode. Set point was 64 and room temp was 55 degrees. I powered off the unit and reset the breaker, waited 15 minutes and powered back on. The blower unit came on and started pumping good heat again. However, I ordered one of your kits just in case there is a leak or the system is low. I installed the unit just over a month ago. This is the first trouble ive run into. No error codes on display. Last night wasn't the coldest night since install either. Just trying to figure out what's going on. Cheers.
Make sure the fittings are all tight, sometimes the lines are not charged completely and need a "top off" but my kit is a great diagnostic tool too! You can see where the pressure is, it has dye to spot leaking fittings or holes in the lines. And ultimately has a sealant that can find and seal most leaks! Anyway feel free to contact me more if you need, Brian.niskala@cnjrail.com I'm here to help.
@Brian E. Niskala Thanks Brian. Question regarding recharging. The unit has to be in cooling mode to recharge? What if the outside temperature is below freezing? Just concerned bout running cool mode this time of year.
@@chrisheyer3974 Great question, always charge in cooling mode at 62 degrees... no matter the outside or inside temperature. When it is in cooling mode, the Suction line (fill valve/line) are at low pressure. When in heat mode, that line turns I to the high pressure line and it will be impossible and super dangerous to attempt to fill that way! But I outline that in the directions, so please be safe. Again super great question to ask during the winter months 😀
@Brian E. Niskala Hey Brian, quick ques I have 2 zones, should I just recharge / check the larger zone or do I have to do both separately?
@@chrisheyer3974 ReCharge at the main Suction line. Should be located at the top of most double plus units. Email me a picture to brian.niskala@cnjrail.com and I will circle which one to use for you.
Did you put it in cooling mode before you started to charge it?
Yes, only, Only charge in cooling mode, temp set at 62 degrees.
I've had the Mr Slim version of this unit heating and cooling a space in my home since 2010. It's worked like a champ for 12 years -- I've never recharged the freon. Just today I noticed the heat setting is not blowing hot air. I assume this is all I'd need to do and gladly order one of your kits if still available.
That's pretty good for that unit. It should just need to be topped off and my sealant will seal any small leaks...
@@GarageMahalLife do you still have this kits available? And is the sealant in the kit or I have to ordered a part?
I have a mini split that was blowing cooled air 3 weeks ago and now that the temperature drops i change the settings to hot and is not working.
@@cesarr.figueroa6402 Here is the link computrader.myshopify.com/products/diy-mrcool-plus-recharge-kit-plus-uv-dye-sealant-all-in-one-fix
Make sure no matter what season you are in to keep it in cooling mode on the lowest temp while recharging unit.
Question! Will this work for a unit that’s not cooling properly as well?? Installed my unit about 5 years ago and it will not cool or heat.
Yes, yes it will 😀
I purchased the one kit and now my unit blows cool! Thank you!
When I filled it it did not reach the blue band I need more refrigerant. Do you know if I can just purchase a can??
Question: I have 4 mini splits throughout my house. 3 work great the blow both hot and cold air. One of them when on the heat or cold setting only blows room temperature air on the heat setting and quits blowing air after 2 mins. Any suggestions?
Is that one the furthest from the air handler outside? Is it a 1 or 2 compressor unit? Brian.niskala@cnjrail.com is my email. It sounds like you are definitely low on refrigerant.
Brian, you never said why the unit was low on gas? Was there a leak?
I did actually in the comments, initial install I had not tightened down the fitting all the way and some refrigerant leaked out... my fault, but it had worked great otherwise, just needed a good boost to have it working 100% they way it should, especially in heating mode.
@@GarageMahalLife I think I have the same problem. My unit is 5 months old. I ran the unit at 86F for 10 minutes. I can see all around the fitting and the caps are oily. Also, the smaller size copper line did not get hot at all.
@@emadtubeyou You definitely have a leak then... call MRCool if it is that new, otherwise you need to definitely tighten all the fittings and get a recharge kit from me.
My high pressure line is hot but the Fan doesn't run inside. Fans does work though when put into fan only it runs. But put it in heat mode and the fan opening opens partially and I don't feel any air
It maybe hot, but it has to be 140 degrees or higher... so you maybe low on refrigerant. I'm pretty sure you need my recharge kit...
just ordered the kit. great video. just what I was looking for.
Thank you! I should get it out today or tmrw at the latest. You will see the tracking info. Later today. Usually 1 to 3 days delivery depending on where in the country you are. Be safe and I'm here to help!
Question: is your recharge kit only for Mr cool or will it work with Premium Nevella? It’s also R410 with very similar features
This kit will work on just about any mini split system that takes 410. Actually it will work on 99.999% of all 410 systems out there! 😀
Installed a 18k mini in January. The air conditioning work fine but found the heating is not smooth always hunting from on and off. Think it’s the thermostat maybe causing it to react too quickly. Think I should mount a remote location thermostat away from the unit. Tried to contact Mr Cool three months ago but cannot get a return call from Tech.
The remote needs to be in sight of the unit with nothing in-between that line of sight. That can and will cause issues. Under the cover of the unit to the right there is a little clear tube of plastic. In there is the units one temp monitor. Get a can of air and blow that piece out. That should help stabilize as long as the refrigerant level is where it should be. These units start losing pressure after about 3 to 5 years.
Hope this helps...
Hi brian I am building a house this fall or next spring an thinking of use if these for main heat! However I am getting nervous here seeing how many people say they can never get a tech from mr cool to get back to them !waiting months?? That sounds ludicrous ! Especially being heat for your family. You also say they start leaking after 3 to 5 years? What is that ?
Do all mini splits leak like this . Thanks for any response you can give me
Looks like this will work on other units not just Mr. Cool. Is that correct? E.G. Senville (inverter)
Correct, any unit that takes 410a refrigerant including dehumidifiers! But yes will work on basically any mini split unit.
Why are they saying I need a full test before I can use your refill kit?
My kit comes with a gauge, which you can use to test your pressure. All in One kit... diagnose, fix, refill/recharge.
I have this problem with a new unit and I had a hvac tech come out. He said that the unit has the correct charge, it still doesn’t work.
Hvac tech, that is all they said? I can help you diagnose it... email me at Brian.niskala@cnjrail.com
@@GarageMahalLife okay so I have the kit sent from you. When I connect the gauge to the port on the unit it is sitting right on the blue and yellow line, 135. The unit blows out at 70 no matter where I set it.
Brian - I have a Lennox MPA012S4S-1P, Mini-Split Heat Pump Outdoor Unit, 21 SEER, Single Zone, 1 Ton, R-410A and it stopped cooling at the beginning of the summer and now that it is winter I see that I don't have heat. Do you think this may take care of my issue? (I know you can't diagnose my problem over the intrawebs) This thing has been a pain in my arse since the day it was installed. I would not recommend this particular unit to anyone...it may have been my HVAC installer. Nevertheless, I am looking for some suggestions and a possible fix before I wire this thing up to a Wile E Coyote blasting machine and turn it into a mushroom cloud. At least then I will get something out of it.
Typically, 90% of the time it is a low refrigerate issue. My kit will definitely get you i. The right direction to check pressure and recharge.
I have one unit with two splits. The kitchen split is putting out heat, but the living room / loft bedroom unit stopped heating. I even turned it off over night (not pleasant).
I would check the filter, make sure it is clean and circulating. And you could still be just a few oz short causing that one lone to drop off in pressure and not circulate properly.
@@GarageMahalLife Thank you. Ordering one now
@@hvasque Thank you, will email you tracking info. as soon as shipped.
Thank you for the video, will this work on a Mitsubishi unit?
Yes, any mini split with 410a refrigerant
Is the unit supposed to be on and running in cool mode when charging? Does this kit work with a 24k Aircon unit?
Yes, charge in cooling mode. Lowest setting 62 degrees, no matter the outside temp. And yes it will work with any system that takes 410a refrigerant.
Will this fox or if it’s not blowing cold air lol I’ve got the opposite problem of everybody else in these comments
My kit fixes no cold air too!!
I have to ask. My diy 18k mrcool compressor starts and only pulls 4 amps but will stop after about 10seconds, then repeats about every 3 or so minutes. Do you stick Im low on Freon? No cooling or heat.
No error codes? But typically a low refrigerant issue 98% of the time. Especially if it starts and the. Turns off right away...
Any ideas on why my Panasonic Split Cooling Inverter one on wall heat and cooling.
Only Cooling works after Aircon people fixed it. It use to heat well but know doesn't get hot even on highest setting.
The Aircon people where very average, not the greatest.
They put extra recharge into system like a gas thing, said we recharged it. That was last Summer less than 1yr ago.
Now we are in Winter our first one since then and it doesn't heat much anymore, can feel it loop warm at 30 degrees if you stand directly under unit.
Any ideas appreciated, thanks
Needs a recharge, has a small leak I suspect. What area are you in? Brian.niskala@cnjrail.com is my email
Also my fan on the outdoor unit doesn’t spin. Please let me know if that is an issue with Freon too. Thank you
That is also another symptom of there not being enough charge in the system. If the compressor doesn't kick on, there is no need for the fan to either...
Feel free to email me at brian.niskala@cnjrail.com with any more questions. I'm here to help.
ever troubleshoot to figure out why its low to start with?
Yes, the whole reason for the video...
Do I do this if my minisplit is blowing cold air instead of hot air?
Depending on your settings, yes, you are low on refrigerant. computrader.myshopify.com/products/diy-mrcool-plus-recharge-kit-plus-uv-dye-sealant-all-in-one-fix

Can I use this on any MiniSplit?
Yes, anything that takes 410a refrigerant, outside unit should have a placard that tells what type of refrigerant your unit takes.
My issue is it's blowing warm not cold not hot will this fix my problem?
Yes, typical low refrigerant that my kit will fix for you 😀
Awesome. Take forever to get a guy out to do this. I can do this myself ! Ordered !

Hi Sir, I hope you can help. I just came across your video. Scenario: I purchased the 36k BTU this fall, but it has taken until today to finally make the final electrical connections and open the valves. I have been wiring my shop and just got power to it. I’m sitting here in the shop and it’s currently 33* inside with the wood stove going. The unit beeps and the louvers come down and the thermostat shows 86* on the indoor unit but that’s it. No heat no fan on heat. If I switch it to fan only it blows but just more cold air. Frozen fingers. Merry Christmas.
Lots of questions... what is the voltage showing to the compressor? Is it set to Heating mode?
How can I get one of those
Link is here and in the description computrader.myshopify.com/products/diy-mrcool-plus-recharge-kit-plus-uv-dye-sealant-all-in-one-fix
Will this fox a f0 code for a mini that doesn’t cool
Yes, yes it will 😀
Can you tell me I have a mini split Mr. cool she is freezing up at the filter on the inside? it is about year and a half to two years old worked fine. About 30 to 40 minutes it'll start to freeze up.
Definitely a low refrigerant issue, my kit will fix that 😀 for you
@@GarageMahalLife awesome thank you well my question is how many pounds does that unit hold and how many pounds is your can hold
Nice video. My unit was working fine and then started throwing a P4 error. Worked with MRCOOL tech and he said fittings might be loose causing a plunger not to work. I checked the fittings and they all seemed tight. I placed wrenches on them but they didn’t move. I had turned power off to the unit at the breaker. After going through the exercise, it started working fine. Tech said the reset with turning the power on and off might have reset something but also there may have been just enough movement in the wrench action to make a difference. That was a few months ago.
Last week it stopped heating after a real cold snap where it ran for 20 hours a day. After watching this video, I may have a slow Freon leak. Does your new kit with the sealant fix a slight leak?
Hi Bob, below is the link to my kits. Yes, I designed the sealant to fix 99% of leaks in these systems. And what you described is the exact scenario I made these kits for. So yes, it should charge, seal and fix your system 😀

@@GarageMahalLife Thanks Brian. I ordered the kit. Here’s hoping this works.
@@BobChristenson51 Absolutely, it also has a UV dye, by chance if it has a big leak, you'll be able to spot it sure enough with a UV light. But my kit typically fixes most issues you can run across 😀
Thanks it worked!
Excellent! I'm here to help and glad I could 😀
Ordered a kit. Do the instructions include how to purge the air out of the hoses before attempting to fill?
One hose, sealed. Minimal air, it is not a big hose that HVAC techs have. Purging air is really not an issue with modern equipment. HVAC techs put that fear so you call an HVAC company and not service yourself... fear factor.
HI, I have mrcool Dual Zone 48K-BTU, I am turning on one of the heads for heating, and I noticed the temperature of the air coming out of the unit changing every 5 to 8 minutes. I set the unit to 75 degrees, and the temperature coming out of the unit started from around 80 degrees, going up to 125 degrees in 5 to 8 minutes, and then coming back down to 80 degrees in the next 5 to 8 minutes. This cycling continues all the time
Please let me know if that is an issue with low Freon
I would check to make sure all the filters are clean, then the sensors (right hand side of head unit in clear tube.) And yes, sounds like a low refrigerant issue, to throw heat it needs to sense 140+ degrees out of the line... remember to use my kit in cooling mode, 62 degrees, all units... no matter the temp outside or in.
Hi Brian - Thanks for a great video. I have the same unit. My heater doesn't work at all and when I put on heat, even the fan isn't working. Do you know what could be the issue here? Thanks
I would see if you tripped the breaker. If the breaker seems good and you have no lights on the inside unit, it could be the main control board that may have failed... but one step at a time.
@@GarageMahalLife thank you
What is the optimal temperature at the blower when in heat mode? Just installed my Mr Cool unit and its at 89 degrees coming out of the head unit. Is the correct?
A lot of factors will affect the output temp. It should typically be within 1 to 2 degrees of your set temp. However if it is cold in a room, let's say 60 degrees and you set it to 80, the output temp maybe as high as 99 degrees until the unit senses the air coming into the unit gets closer to the programmed set temp. Then it should continue to blow out at the set temp. In this case close to 80 degrees...
Just ordered a kit myself, I have the 24k unit and it had been working great even when it got down to the teens but suddenly its only acting like a fan regardless of what mode I put it in. The outside unit is making noise like it's trying to move the gas but the fan never kicks on. I did notice yesterday it had to defrost like 3 times but I didn't think much of it since we have been getting freezing rain due to the winterstorm rolling through. It's currently 35 out and the outside unit looks find (no ice or snow on it). I can't even get it to pump out cold air in cooling mode just blows air like its in fan mode. Im hopeful that it's just low so well see what this does. Cheaper to just try this than to call the HVAC guys out to even look at it. I'll go down the road later if needed lol.
I will get your kit out tmrw... did you happen to measure the temp of the lines? You need it to pump at 140degrees plus. But from what you described, it is low on 410a...
@@GarageMahalLife well it took the whole can and never hit the blue. It did pump out heat afterwards for about 10 minutes but then went back to ambient air temps. I'm thinking I have a significant leak somewhere. Calling an HVAC place now. I could here a hiss coming from inside the outside unit but I guess I'll see what they say. Thanks again.

Just curious. Do you run the unit while topping it off with refrigerant ? I ask because the automobile fill kits state to run the AC with the windows down while topping off. Thanks.
Yes cooling mode 62 degrees, no matter inside or outside temp. Charge in Cooling Mode Only
If I already have gauges and adapter, will all I need is the can of refrigerant?
If you got the gauge and adapter from me, yes.
How do I purchase this kit
Here is the link computrader.myshopify.com/collections/frontpage also in the description 😉
The air conditioner must be on while the procedure is done?
Yes, in Cooling mode only
Hello, I have Pioneer Diamanté Ultra WYT-22 Inverter Series it’s showing an E4 error code on the unit do you know if that is why it’s not heating? And would this be the fix . Was the unit in this video throwing an error code, if so what code. Thank You
Yes a P4 can be attributed to a low system leak. My kit will help fix and seal the leak, while bringing it up to the correct operating pressure/temperature.
I have a MrCool Universal inverter heatpump system that throws a E3 code. Seller Ingram's said it is low on refridgerrant. The E3 is a protection mode so the unit wouldn't start due to this mode. How would one recharge this?
Turn unit off, wait 10 minutes. Have my charge kit ready. Then turn unit on in Cooling mode on the lowest temp, usually 62 degrees. Charge with my kit and all fixed! 😀 email with questions Brian.niskala@cnjrail.com
Is it possible to use the entire can and it still not get to the blue?
Yes, that means it went for a while without running and noticing it was not working properly. And or could have a small leak or faulty fill valve.
I am still watching this video even though it doesn't address my issue. But it seems that my issue is not common enough for there to be a video... So...
What if:
It seems as if the temperature setting is 10 degrees higher than the room temperature when cooling?
:: If I want the room cooled to 76 degrees, I need to set the mini split temperature at 86 degrees? (Last summer)
:: If I want the room cooled to 66 degrees, I need to set the mini split temperature at 76? (Last summer)
:: Now, I set the cooling temp to 88 degrees, but woke up to the mini split still blowing cold air and my space at 54 degrees and lowering. (This summer)
I am inclined to think the temperature sensor is bad, since I had similar results in the winter the couple of times I tried the heat, ie. a 10 degree difference between mini split setting and space temperature. But now its summer and the thing wont stop cooling even when set to its highest temperature.
If you know an answer or have a suggestion (anyone) I would greatly appreciate your input.
I would first clean the inside air unit, take the filter out and blow it out with a can of air or air compressor set on 35lbs or less. Outside unit, with lower water pressure clean the compressor area where the fins are... avoid too much pressure avoid bending the fins, aim straight on. Clean the inside filters really well. Now that the units are clean, see what the Temps differences are. Download the MrCool app and see when the units Temps registers at. Make sure your MrCool remote has new batteries and also is lightly blown out as well to get any dust out. Then if there is still a temp issue, then the sensor would have to be replaced, more than likely the inside unit's temp sensor.
I have the same problem with my Mr Cool!
We have a single mini split, everything works except no heat!!!! I called Senville and they are not much help. I checked the pressure but it was at 0. Fan works, ac works.....it was cold outside, also turned it up to 86 degrees and large copper line was not getting warm on unit at all............Please HELP. I checked all the lines with soapy water and no leaks.
Hi Christine, email me at Brian.niskala@cnjrail.com
I'm having the same problem
@@normanweagantjr7982 Sounds like you need to order my ReCharge Kit
Is this for not heating problems?
Yes and not cooling issues too. Heating becomes a problem 1st on low refrigerant, then cooling suffers layer on as a potential leak continues. My kit will seal most leaks 😀
When on cooling setting set at 70F what should the air temp coming out of the MR cool unit be?
Depends on the room temp... but around 70 give or take a few degrees below that number. If the room is in the 80s, you would see temp out puts around 55...
We have a Ramsond unit; no hot air this morning. I will have to find which refrigerant it is using before I order (won't I?) Good video!
If it takes 410a which it should, just double check on the outside fan unit. By the copper lines it should say what refrigerant it takes. If it's 410a my kit will work for you 😀
@@GarageMahalLife Thanks, will get out there today.
@@Anvanho when you order, I usually finish shipping by noon, otherwise I ship same day and or next day.
@@GarageMahalLife Thanks! The odd thing is, though, the ~ac works great still, so there must not(?) be a leak so I now wonder if the coils are in need of cleaning?
@@Anvanho The core valves tend to leak after a few years, my sealant fixes small leaks. Cooling mode is easier on mini splits and doesn't need as much refrigerant. Heat mode however needs just about perfect pressure to generate 140 degrees to have the cpu and sensors work efficiently
Brian, wondering if I need your kit. My unit (36k multi room) was working great but I was using it a LOT recently in the cold weather here in TN this past week. Last night it went into DF multiple times then stopped heating and threw a P6 error code. When I checked the air handler the coils were white with snow :) I defrosted them with a hair dryer to get rid of the ice. Since then I don’t get hot air, the fans start up fine and the heat pump and fan come on outside as well, just never get anything but cold air. I did get a P6 one more time but since then I get no error codes, it just never heats up. Think it’s just a recharge? I’ve had it running for 1.5 years with no issues until now.
Also one more question, if this is the fix, do I need to fill it in more than one valve since I have two air handlers?
Btw both air handlers had the white frost on them when this happened
Hi Jason, yes seems like a classic low refrigerant and my kit will fix that. I have sealant in the refrigerant so it will seal most leaks and typically any future leaks as well. If you have 1 air unit outside, one kit should be fine. Feel free to email me with any more questions Brian.niskala@cnjrail.com
@@GarageMahalLife thanks! I’ll get in there tomorrow and order it
@@jmatech Did you order the kit and did it fix your issue? I'm having a the same issue right now the a multi split 36k Mr Cool unit as well.
I did and it did help some, however I actually discovered that a family of mice decided it was nice and warm in my control compartment/abs box. They decided my wiring was better used for a nest than for my heating. Mr cool sent me all new wires and a controller box and accessories and I was back up and running.
Would like a recharge kit with gauge for my Mr Cool mini split that is not cooling or heating

Hi. I've been running a MrCool 12000 BTU Advantage unit set up by a local HVAC company after I did the physical installation. Been running and working fine on Auto in TX for 2.5 years. Just this past week, I hadn't been in my mancave for 9 days, I went in and it was really warm at 10 pm. Ugh oh. And I have guitars in there. The 20 A 240 breaker was tripped. First time. Hmm.. Reset breaker. Watched it for a few minutes. No other trip. Checked that the inside unit was blowing cool air as is expected. It is. I let the place get to temperature overnight. And this morning I decided, I need to test the heat. So I put it on heat setting and on 80 degrees. Gave it a couple of minutes and nothing. No heat. I would think if it was a freon issue it wouldn't have gotten cool the way it did. Thoughts? I just read on a link that it might be the reversing valve in outdoor unit?
So, the tripped break is something to note and keep an eye on. I've delt with a bunch of bad breakers these past few years, but only if it trips again, maybe check the load to the breaker and decided if it is too much amp draw, could be a compressor starting to go. However if it seems to cool okay, but not heat, definitely a low refrigerant issue. The unit needs over 140 degrees to kick into heat mode, if it doesn't reach that temp, it usually is a low refrigerant issue about 98% of the time. Mini splits seem to work OK cooling even with less than ideal refrigerant pressure. Heat however needs to have spot on readings. In summary, low refrigerant and keep and eye on the amp load of the breaker as it could be a compressor issue... once you charge it up to pressure that is.
@@GarageMahalLife Thanks for the quick response B. I'm always puzzled by units that get low on Freon. I've had a Dodge Magnum that 17 years old and never needed a freon charge. And still works fine to cool. And my main house AC, the only time freon was ever low was when there was either a leak at a pipe at the outside unit or the evaporator developed small leaks in the attic. But that was a much older system. The pipe leak I had was just a crappy Goodman unit and a better service place fixed the leak and I didn't leak freon for many years after that.
So I guess my point is, this unit is so new, seriously would the compressor be going out this soon? That would be sad. And if it has leaked refrigerant, that's weird too. But then again, I'm not a pro and I decided to hire the same company that set it up in 2018 to come out Wednesday and check it out.
But I do appreciate the insight about why cool might work and heat not. Yeah the fact that I have a 20 amp breaker is actually 5 amp higher than a 12k btu is rated for. Should work fine with 15 amp. So blowing a 20 amp, that's quite a jump in current draw. I wonder if when it switches to heat and it's not able to do it's job, that's when the current is going up. Well I will let the pros give it a thorough going over. I have too many expensive guitars in there to risk a failure.
@@cranstjs ReCharge should do the quick, just covering all bases with the breaker... why these units tend to "leak" is the fittings and fill points have small O rings made of silicone. The cycle going from hot to cold strains them and they get micro cracks. My kit has in the refrigerant a leak fix, so it will fill those micro cracks and prevent future and current leaks...
@@GarageMahalLife Followup after HVAC guy visit. Told him the story. His impressions:
1. He saw one of the safety box wires was a bit loose and tightened that. Not sure why that would trip a breaker or cause any other problem. And did a current test and it was less than 4 amps with AC on.
2. Cool working fine. Filters fine. Didn't want to check refrigerant because he said breaking that connection would mean you would lose 6 oz right off. Then you could re-add but then you would have to recalibrate. Ok. That's all Greek to me. But he basically said as cool as it's getting it's unlikely you are low on that.
3. Tested heat function. Not happening but he said, because the freon was probably really warm, it's possible that being too warm that it probably wouldn't come on. (99 deg out in TX). And really, why would you ever want the heat to come on when it's that hot? And it's offering protection from too much head pressure if the sensors say it's too hot to turn on heat. Again over my head.
So I made sure the service ticket stayed open because so far in the 20 minute visit, all I got was tightening up a terminal that was a bit loose and looking over the rest. So next week it's supposed to drop into the 60s at morning so that's when I can test the heat. If it works then, we're good if not, the service ticket is still active for 30 days of guarantee for what I paid for.
@@GarageMahalLife Final test. I found out range of MrCool to have heat work is 32 to 86 degrees out. Wouldn't work at 88 deg or higher outside. As soon as it hit 85 deg at 11 pm here, I tested heat again, and voila, it works. So everything seems to be ok with it. Just need to keep an eye on power after errant breaker trip.
Does your Recharge Kit work on other Heat
Pump Brands?
Absolutely, if it takes 410a Refrigerant it will work. Just look on your outside fan unit. The placard by the lines should say 410a, if it does you can use my kit! I have an adapter in every kit so it will fit 99.9% of units!
Is this common for all ductless units?
Mostly, they ship with just enough gas, the moment you have even a small leak, it drops below what is needed to drive the heat part of the unit. They can cool with a low refrigerant but not heat...
If the pressure is ok, but stops heating after its automatic 'defrosting', do you think it is the electronics or the four way valve? This is a Mitsubishi Mz.
How often does it go into DF? Filters and coils clean inside and out?
@@GarageMahalLife When I got it to heat, after being shut down for a longer time, maybe half hour. It is clean. And it has correct pressure. I just wonder what to bry for, electronics or 4valve. There had been some power shut downs before it stopped working.
Hey Brian. So we have enough pressure, and freeon. It blows cold, but when you turn it on the heat it does Nothing. No air is blowing. Anymore suggestions? Thanks.
It does need to heat up outside in the unit and then heat the coils up inside. Then it will start to blow the hot air. Once it hits temp... it can take 5 to 10 minutes. As long as the pressure is good, filters are clean, it should start blowing hot warm air. Put the unit to 82 degrees to make sure it is at the a good temp. If you set it to 72 degrees and the room is actually 72 or higher, the unit will not kick on...

Brian - I have a Fujitsu split halcyon unit that not heating. Are you saying to add Freon and even in. 30 degree outdoor temps I should place unit in air condition mode leave it on and add Freon while unit is running in ac mode? This will help heat? Thanks,
Yes, put it in cooling mode. Even when the temp is low. If it is in heat mode, the compressor runs backwards and the charge line becomes the high pressure line and you will not be able to charge it. Anyway, leave in cooling mode to charge.
@@GarageMahalLife Hi
Problem I'm having is when I place it in cooling mode to charge it dosent kick over. Its winter where I am now averaging between 35-50 degrees. Any suggestions on what to do to get the a.c. in cool mode/run.
@@TheBlindSwordsman You have maybe a 5min window to charge... turn the unit off, be ready to charge outside. Have someone turn the unit on in cooling mode. You'll hear the compressor turn on when it gets enough pressure in it. You may have to repeat this process if you are not fast enough. But follow my video, charge it slowly, but be fast and safe in the process if that makes sense...
@@GarageMahalLife Yes makes sense, so to recap.
1. Be ready to charge outside while unit is off.
2. Have someone inside turn the unit on in cooling mode
3. Wait until the outside unit kicks over? Or inside unit?
4. When it kicks over press to charge with the refrigerant?
The one thing I'd like to know if everything else is correct is should there be a desired temperature the unit inside be set to, or does it matter?
Thanks for the response and help thus far.
@@GarageMahalLife Another thing, I wasnt clear about having a 5 minute window to charge, why is that and does this start from the time the unit kicks over in cooling mode?
When I connect my kit to my unit the gage jumps to the red area, why would that be?
Units must be charged in Cooling mode on the lowest setting 62 degrees only. Heating mode is not to be used when charging mini split systems.
Where can we order this kid ?

I have the DIY Mini Split by Mr. Cool. Out of the box the hot air is not blowing and the AC is not blowing cold air. Unless it's only supposed to blow actual "cool" air. Everything was hooked up and tested by professionals but I cannot tell if I need the $140.00 refrigerant or if I can use the warranty. Anyone with tips?
If the unit is that new, contact MrCool for warranty information. They do take a few business days to get back to you, but they will. But it sounds like a low refrigerant issue... checknwith them 1st and I will be more than happy to help you after if needed.
I have a Mr Cool 24000 BTU .I have no heat and when I hook up the gauge it's in the red to the top.
Hi, what do you mean in the red to the top? Do you have my kit or your own gauge? Feel free to email me Brian.niskala@cnjrail.com
Last I checked one needs to be EPA 608 certified to connect to a refrigeration circuit and/or purchase refrigerant. Correct me if something has changed.
I purchased your kit and cool air is now flowing. I was only able to get to 95-100psi before the product ran out though. What do you suggest? Thx.
Sounds like you were really low on refrigerant... you can order a single tank from my site, I ship by noon daily EST. You need to be in the 125-135psi range for the best efficiency, or half to 3/4 in the blue zone on my gauge.
@@GarageMahalLife Thank you for the quick response!

How do I do this on a multizone system? Do I have to charge each one if more than one is low? I have a MrCool 36k 4 head DIY unit by the way.
It goes by compressor, so yes each one would have to be charged. In these cases I recommend getting 1 kit and an extra tank.
Do you charge it with the unit running?
Good question, yes you need to have it running in Cooling mode...
Thank you
I just asked the same question..I guess I should have read more comments..
@@GarageMahalLife Hi
It's winter now where I am. When I put it in cooling mode to try and charge the system it won't turn over... Any suggestions?
Could it be possible that it can still be low even if Mr cool sent you precharged line set? I hooked them up but it’s not blowing cool
Yes, very common. MrCool charges the line with the bare minimum. Very easy to lose some refrigerant on install and thus your system will be low and not work properly.
@@GarageMahalLifeok I’ll order the kit I just don’t know how much I lost do u have a number I can reach have another question to ask
