Your Amazon toolkit has more nice toys than Santa Claus has! Looks like I'll need a small loan so I can buy some of these...🇺🇸 😎👍☕
One thing i recommend is doing exactly what you just did but cleaning the coil from the inside of the unit.
I've been watching alot of ur videos I went to schooling for hvac but sadly the schooling didn't care to train us and just give us the answer for the test now I am paying off a loan I didn't get no training to
As a retired HVAC mechanic with 35 years of experience. I have one tip about foaming coil cleaners ...... always start at the bottom and work your way up. The reason being is that the run down of foaming cleaner can prevent proper penatration. If you start at the bottom and work you way UP..... You always have coils with NO FOAM IN THE WAY. JMO. WORKED FOR ME FOR 35 YEARS....LOL
That’s a really good tip. Thanks so much!!
@@diyhvacguy
I got a million tips. But you seem to be killing it on your own. Good videos, good editing skills , and no fluff. I like that.
@@diyhvacguy have you ever run into a TRANE with bottle brush fins.?? When I was a rookie. I had to call my boss and ask what to do. He told me that TRANE recommended removing the complete outer shell of the unit. Then, take your torch and burn off all that you can. Always being mindful of burning fins. Once that is done. Clean from the inside out. .... worked like a champ. Once you've burned the outside and cleaned from the inside out. You MAY have spray the outside and inside and clean again. Your professional eyes can tell if you've done a good job. Pain in the hindparts... but it works.
Something went wrong. I was speaking of a TRANE with bottle brush coils.
That's a great tip. But, if one spends the time to read the manufacturer's instructions, they will find it is also the recommended way to clean the coils.
This is no joke. My unit is 4 years old. Cooled my house like a champ the first 2 summers.. The 3rd Summer it struggled mightily to keep the temp below 80. Nothing changed, same ole house, I thought maybe it was just a hot summer. I had an A/C guy come out to check on it before the spring and he was like everything is good but you need to clean this unit its dirty. Now I couldn't actually see any dirt on it for me to call it dirty but he explained "I've since verified online" that the smallest amount of dirt/dust on the coils can change the efficiency of any unit. After he left I cleaned my unit with simple green and could immediately tell a difference in the coldness of the air coming from my vents. I'd advise cleaning at least 2 times each summer in the south and maybe once in the winter.
If you had a guy check on it
In spring and just told you that your coil needed cleaned, he failed you. The whole point of preventative maintenance is to prevent a break down. He should’ve cleaned it. It takes 10 minutes.
@HarryHafsak he got paid for a check up not a clean up do u know if it was micro channel? did it have hail gaurd ?was it a double coil? did u need to completely take the cage off like a rudd ac ,or was it really dirty where u have to remove fan and clean inside..... 10 mins u say ???😂😂😂😂
Takes way longer than 10 minutes. I do mine once a year in North Texas.
@@BLACKMONGOOSE13am in north Texas as well. Do you clean from the inside or just spray from the out with just water?
I just saw your video. Ordered a good product from Amazon. Did the same. after 3 years or so no cleaning. It was dirty and she is spotless now. great video. Thanks !!! I took the whole covering apart. This is a must for all to do.
Is it necessary to take the cover apart if cleaning/spraying from the outside.
Incidentally...I thought it was usually cleaned from the inside
This is super helpful, I am going to clean mine this weekend, it is always better to do the maintenance then wait for trouble. Thank you
Big thanks for demystifying my air conditioner. A few tools and now we can save a lot of money. I really appreciate the info.
Scottsdale AZ here, I have three 5 ton units servicing my home. I spray my units with an aerosol every spring, in addition I hose the units down 3x a week (gets really hot here), I'm not taking chances, and I'm definitely going to order this solution. it looks like a good product.
I got a car foam canon that was exactly this model (except it had a red cap and no writing) for about $20 from Walmart a few years ago. I just fill it with diluted dish soap and it woks great for keeping my 38 year old York AC unit running. Plus it has many many uses around the house, from car care to exterior cleaning.
A neighbour said her AC did not work very well any more, I took a look and it looked like some one had wrapped the condenser in a carpet, it was so plugged like i have never seen before!, i removed the cover (after the disconnect) and unwrapped the carpet of grass clippings, and washed it out thoroughly, Worked fine after that, told her to mow the lawn in the other direction instead of shooting it into a running condenser,
Yea it’s always a good idea to pull the disconnect when cutting grass around it. It acts like a vacuum otherwise.
She is lucky to have you as a neighbor. Avoided a shady company looking to sell a new unit. A lot of hvac companies try to sell stuff you don't need or employ techs that dont know what they're doing.
I bought my house a couple of years ago and had a home warranty when I first moved in thankfully whatever was wrong with the AC. They completely replaced the condenser unit for free since the previous homeowner paid for the warranty in my contract. I’m going to start cleaning my condenser unit. Thanks!
Home warrenty by choice home warranty is waste of money. I don’t recommend
@@Andy3-4 thankfully mine paid off and I didn’t pay for it. When you buy a house you can put it in the contract. They didn’t cover the garage door but replaced the condenser unit.
@@IMGDirect new home ?
Just spoke to a Nu-Calgon rep and he said that due to the caustic nature of Nu-Brite on aluminum, use Tri Pow'r HD. Nu-Brite is for aggressive cleaning and if you are just maintaining could eventually eat through the aluminum if used continually.
Great videos! How about making on on cleaning the evaporator coils?
I always recommend, if possible, to not run the A/C while the lawn is being done. That in itself loads extra dirt and grass debris.
Good tip
I guess I never really thought of that being an issue. Thanks for the great advice.
Just mow so the discharge points away from the a/c unit
@6:39: Rest assured, the "home warranty" program would've denied her claim no matter what. Home warranties are a total scam.
I used to work at a home warranty company, and while this is partially true, you would be surprised how much we've paid for customers who have read their service agreement and know when something is eligible or not before wasting everyone's time. This is going to also vary by who you are "protected" by of course.
My husband works as a plumber so he knows how to get around the maze of home warranties. One thing he always tells his customers is to buy the highest coverage. Almost always, the customer would think because they have a warranty that things are covered. Basic coverage, imo, definitely seems like a scam. Barely anything is covered in these instances.
We have top tier and have actually gotten our money’s worth.
Yeah, I stopped using them because whenever I would look up the reviews of the companies they sent to fix stuff in my house they had terrible reviews and there were always issues. If the first company did a terrible job or didn't fix the problem and you want a different company you have to pay the service fee again. Better to just put that money to the side in an account for home maintenance and then you can use whomever you want.
2-10 Warranty - SCAM
Covered almost nothing. Waste of money. Work with a good builder. That matters.
True! I learned the hard way😮
Saw this video and followed your suggestion. I bought and used this cleaning system on my two coils.
This product WORKS ! The before and after was night and day. This is worth every penny!!
This is good my guy 👏🏽👏🏽!! About to graduate hvac school in may
@Jhill I finished my HVAC school in July 2022
Congratulations!! Proud of you. Has it been a busy summer?
I find all you're videos helpful, Thank You.
Thank you so much 🙏🏻
Great advice 👍 I wash my unit at least once a month during the hot summer months. With anything proper maintenance is key to longevity and smooth operation.
weird. I went 12 without even looking at my unit in anyway. I did not you were supposed to. the previous owner had it for 5 years and said nothing of maintenance and the new owners have had it for 3 with no issues last I checked.
so it's been in service for 20 years of flawless service blowing cold air to 5 bedrooms
and you are having to clean yours every three months to get cold air
@atheistpeace7579 it's like changing the oil in your car.
@@bigcountryjd cool. I just don't understand why mine has run top quality for so long with zero maintenance
@@atheistpeace7579 me too. And I live in a very dusty mountainous area.
@@atheistpeace7579I cleaned mine and the air out the vents is almost twice as cold as before. Of course mine was almost completely blocked.
Thank you! Please could you do a video on how to clean the A coil. My A coil is on the unit in the attic. But not sure how to get to it. Thank you!!
Buy the biggest bottle of DAWN Dish Soap. It’s good for your drains/toilet. Also good for cleaning you A/C unit. And if you happened to get pepper sprayed in your face, also good for washing cleaning your face and good for washing poison ivy off your skin after direct contact.
Believe it or not Dawn soap is what airport fire departments use to put out airplane fires after a crash. Many people don't believe that, thinking it's some type special fire fighting foaming agent used.....but it's true.
Thank you very much I love the mace, advice 😅😅
yes sir!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Kills wasp extremely fast as well
What do you experts think about a leak (main copper from the compressor) right after I used Nyco coil & fin cleaner? 10 yr old Goodman A coil, inside fan motor still humming.
We have trouble with the cotton wood flying around at times in the summer, 1-2 times a week i have to blow it out. Sometimes i put the screen cover over my unit. But still keep it blown off .
Nice i learn something new today i gonna put it in practice this summer thanks 😁
Not sure if it's here but foam OUTSIDE and spray water from INSIDE. You want the debris to move in the opposite direction of airflow. Otherwise you tend to force material INTO the coil instead of out.
Yes thank you I thought so
That’s the whole point of taking the top fan off, right? If you’re going to spray from outside and it doesn’t seem, there’s a point of taking the fan off. I’m getting ready to clean mine for the first time so I appreciate your comment.
You're putting way too much thought into this. Just rinse the fkn thing. It will be fine.
@@themonsterunderyourbed9408 Im going to rinse one side north to south, the other south to north. And the adjacent sides form east to west and west to east. I'll do once side during a waxing moon, and the other during a waning moon. I"ll report back soon!
@@GregoryGuay 😆😆😆 awesome.
Actually, im a truck driver and we use a an aluminum cleaner for all of our aluminum rims and trailers, so i just make some for my a/c, works very well.
Very bad idea anything acidic will damage the coils they are very thin and expensive.
I have a Trane XL where the coils are mostly enclosed. Will I benefit from cleaning the coils like this?
Nice video !!! Very helpful
Or you could just take your pump-up garden sprayer and fill that up with cleaning solution.
That's what all the pros used before New Calgon came out with this type.
VIPER coil cleaner works great as well in one of these foam canon’s! Just did a couple units today. Mikey Pipes uses it so it’s gotta be good!
Great training vid, worth the watch and follow, Thanks for this!!!!
A good buddy hvac tech told me to not use the blue solution shown bc it can damage the coil by eating away some of the metals making them easier to corrode and ultimately ruining it in a shorter time frame. Curious on your thoughts about that?
Great tips every time a tune in. Thanks🇺🇸 7:59
I switched to Viper pack cleaners a couple years ago,the Nu-brite will eat your coils over time,the Viper is micro channel safe and wont hurt even if you dont get then rinsed completely! I used the blue for a long time,it is very good on filthy coils,but I dont let them get that bad,but evao soap is my go to for maint purposes.
Yes that’s the beauty of that’s foaming coil gun. You can set it to E and it will ration out 10 parts water to 1 cleaner. A gallon would last forever.
@@diyhvacguy Excellent
what is evao soap?
@@DerpMcDerp101 evap, it was a typo! Or maybe I had too many cold deers that night!
Dawn dish soup and warm water is all you need
will be doing this shortly.!
looks easy enough and a cooler house is worth it!
Excellent Idea!!!
ive seen video using dawn soap. Does that work as well?
Thank you for the advice
Thank You Sir, Appreciate the home warranty info...
Any other recommended preventive maintenance I can do to a unit?
WoW! So true with home warranty companies.
Have a home warranty company and they will find any reason to avoid paying even though you’ve paid them TWICE over what they SHOULD pay for, per the contract agreement. Yeah, been there and done got what they owed. But I must say that ours was worth the monthly payments because eventually they paid for the entire repair/replacement. Not only our A/C but a few other major household appliances. They will balk at first but just stick to your guns, err, cajones.
This is a foam gun for washing cars (the predecessor of the foam cannon). This is a great use for the foam gun because it uses lower pressure and you can control it. Don’t use a foam cannon with a pressure washer. It can damage the fins.
Foam cannons on a pressure washer don't output high pressure though... Probably fine to use to apply the cleaner, but don't use a pressure washer (with a nozzle) to rinse.
I use a foam cannon in the radiator of my bike several times a week, when I’m washing it, and have never had a problem. I also rinse it with my pressure washer, and haven’t bent a coil fin yet. You just have to be careful, not spray from the side, and not spray it too close. After a couple feet, the pressure has dissipated greatly, and the water is more atomized then it is a direct stream.
BUTT, if you BLAST all the cooling fins off your condenser coil,
You'll NEVER have to clean it again ! B-)
That's what I was thinking. Doesn't seem to be any different from a regular foam gun.. Or am I missing something?
@@nickydexgg4579 This is what I'm thinking, just use the pressure washer to get more foam/better coverage in less time than the gun. Then just turn off the pressure washer and use a garden hose or jus use the same pressure washer wand but with the pressure turned off.
Great videos, done the right way..
What is the blue liquid solution you use that's inside the bottle you use to spray
Good job, thank you
LOVE THIS GUY!
Great advice. Thank you for this!
This is especially important for mini splits. Even if it doeant look dirty, it probably is.
Did you spray the Foam from both sides (inside & outside)? Thx
I have a new home, and occasionally my ouside unit makes a loud noise when it shut off. What is that and how can I fix it?
after replacing the fuse in a Lennox XC20 -48-230A01 I get a OU Inverter Communication Error code 434. Any suggestion?
Anyone know where to get replacement tips for these spray bottles?
Nu calgon has a whole line of sprayers and sprays for different applications!
Spray from the inside out for best results, this requires removing the fan and shroud, thou there is one tool I'm aware of that allows you to insert a wan through the fan and blast out.
This had a double coil so spraying from the inside would do nothing. It wouldn’t have enough force to go through both sets of coils.
Question, I have a ducane condenser 3-ton unit. I used a mister on this condenser for two seasons and now a few of the outside and inside cooling coils are corroded and falling apart. So later I would like to replace the coil only if possible since the fan and compressor still working fine and to save money and not a new system with R410A. My unit is approximately 18 years old with R22 coolant. Is there a replacement cooling coil for this Ducane? I saw in one of your vlogs that you replaced the condenser from a garage roof with a RUUD unit. The unit you removed looked like a Ducane brand and could be the same size as mine seer 13 and believed to be a 3-ton unit. Again, thank you for showing us how to DIY
Thank you for this!
Very helpful 👍👍👍👍
Killing the disconnect doesn’t always kill power. I’ve had it where I assumed power was off by doing this but one of the prongs got stuck in there and you wouldn’t even notice. Well I still had 120v in the unit. Always check with a meter if you are gona work on the AC . Never assume.
Good point. Thanks for the tip
If you kill power to your AC unit and there's still.power going to said unit you may want to call an electrician and have them see why you have power when the power is cut off. That's how fires get started.
@@jonboatmorava9115 if you’re not qualified yes call someone else
Always that one in a billion scenario
Very good video...thanks a lot my friend!
Question by the way! Is it a good idea to put a cover so it nothing would stick to the condenser?
What about white vinegar would that work as a cleaner on coils
Should you try to spray from the inside out?
What detergent are you using and are safe for the fins? TIA!
Purchased: August 2022 - still works GREAT! th-cam.com/users/postUgkxxsUnXhGsSJLim_XnMHyQK0u3XVaW-CGn I 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!
Is it true that trane units recommend cleaning without any kind of cleaning solution?
THANK YOU SIR , MUCH APPRECIATED 👍
Interesting. 25 years in same house, with 2nd condenser/ac system installed about 5 years ago. I have never seen anyone clean my, or anyone else’s condenser coil. I also just went out and looked at mine, it looks the same as the day we installed it. Shiny Aluminum fins. How is everyone getting stuff stuck in the condenser???
You should do a video on the 100 different colors of coil cleaners....so many options......
Good idea! Thanks for the suggestions
Love your channel; I think what you're doing is great. I have a question though: what is the chemical you used in the sprayer? Is it Nu-Brite? Is it safe to use on aluminum condensers? Thanks
Great video! A cheap pump sprayer works great to spray the solution.
My HVAC guy recommended Dawn and a similar hose attachment, non-specific to AC cleaning -- Would you say this would do a sufficiently better job to justify the cost?
For home owner application it’s probably sixes. I like how it foams though, very satisfying 😎 cheers
2 questions,
#1 what soap did you use in the foam bottle?
#2 i already have a foam cannon i use for car washing. Any reason I can't just use that one on the AC?
You can use that one you have for sure. It was just dawn dish liquid and vinegar 👍🏼
Just purchased the foam gun and detergent from you..... Great tutorial as i am out here in the dusty Arizona desert
Fuck that
@@brandonbell5357 After twenty years here i agree with you
@@notwrkn2mch LoL
For an everyday homeowner, what’s your thoughts on the
Nu-Calgon Triclean 2X Coil Cleaner vs the foam spray gun and concentrate?
It’s about $25 on Amazon vs the $150 investment in the gun and foam concentrate.
My coils aren’t overly dirty (that I can see) and while I’m sure the gun would be best, do you think the Triclean 2X is still better than just an aerosol foam cleaner in a can?
Any videos on cleaning the insides coils in the home?
Is this blue chemical safe to use regularly or just for heavy buildup ?
Can u use this on ur car’s condenser?
I usually wash mine down on a regular basis. I don’t want dirt to build up on my ac.I’m always checking it.
Do you have a video about how to do a DIY Preventative Maintenance. I have a guy come out and do it spring and fall but would love to do one of them myself and save a little bit and learn something in the process.
Will be doing one soon!
Foam cleaner I use for tough neglected jobs, toilet brush works well and I bet you have an old one lying around!
Any suggestions outside of Nu-Calgon? Dawn? Simple Green? Also... how long do we need to wait before turning on the unit?
You dont even really need any cleaner. Buy a soft brush and brush the coil out first then rinse the coil out with a hose and nozzle spraying from the inside out. If you're using a nozzle with decently high pressure, take caution to spray head cuz if you spray it at an angle you can flatten the fins on the coil.
Dirty units need cleaner. VIPER makes one of the best that’s the proper Ph so it won’t attack the aluminum of the condenser.
You can also use a car wash foam cannon” which is the same syphon type can that make foam. About $29 on line.
or a Ortho hose end sprayer with DISH soap. it will clean it fine. or a pump sprayer with dawn-palmolive or ... certainly will improve it.
I got a car foam canon that was exactly this model (except it had a red cap and no writing) for about $20 from Walmart a few years ago. I just fill it with diluted dish soap and it woks great for keeping my 38 year old York AC unit running. Plus it has many many uses around the house, from car care to exterior cleaning.
Is there any difference between the foaming device used here and a car foam cannon (on the end of a portable low pressure pressure washer) with a premix of the cleaner in the percentage you want to use?
I was wondering the same thing. I’ve got a foam cannon and only difference I can tell is it hooks to a power washer. It’s not recommended to use a power washer to clean AC condenser, the foam can in on a power washer isn’t a powerful stream.
@@troyd.521 Actually, the foam stream I get with my 2700 PSI full sized pressure washer isn't particularly strong at all, and seems no different from what comes out of the one I have on my 600 PSI portable washer (which is what I'd use), which isn't strong either.
Can we use a scrub brush or no?
Are there any advantages to cleaning the inside as well? I usually spray can foam my unit twice during the summer season, but only from the outside.
If your unit has 2 walls of coils, just spraying the outside will not get to the inside coils and will not clear up the debris and gunk on the inside wall
@@093jmartinez Thanks for your response.
Since the unit inhales air the best water clean will be to push mold, pollen and dust OUT by spraying a hose from the inside with the top removed.
The majority of the soap should be outside...but the majority of first attack rinse should be from the inside....then spray off the outside.
Some units give you little or no slack in the upper fan wires, so you may only be able to get a lift with a helper unless you remove the fan from the cover...a bit of a pain for a 15 minute job...and more chance to screw up.
In that case a hand holding a hose nozzle is all you can easily get inside.
Small dish soap squirt bottle with 50:50 dillution also does a great job of getting soap into the coils...and thats basically free.
Always go from inside out
Thank you so much
Looks good for the coil outside remember there is a second coil usually called an A coil inside the furnace that needs cleaning also .
Evaporator coils, also called a-coils, seldom if ever need cleaning. They stay clean because the air is filtered and the wet coil self rinses. That's why there isn't easy access to the evap coil in most installations.
@@johnwilcox4078 that would be a 2 part system . My mistake for not being clear . I was referring to a Goodman all in one package system . Our old one failed due to no filter ( lousy instal ) and the new one wea also installed with no return filter ( lousy installer ) also all the ducts were taped together and fell apart .
Hello. Do I still have to turn off the electrical power if I just spray the HVAC unit with a garden hose, but I don't open the top lid? Thank you for the videos.
You don’t need to but it’s advise that it’s off while cleaning. They’re designed for any weather conditions so leaving it on won’t harm it.
@@diyhvacguy Thanks again.
I have a train 4 ton condenser but the coils looks like chrome stencil that you would wrap around a Christmas tree an would I still clean them the same way like you're doing in this video, it's a new unit only 2 years old but down road.Please advise if you can.
Yes you can use this same foam gun, however I would use Nu Calgons Nu Clean which is a yellow cleaner you can buy by the gallon. The fins you have are called micro channel. But you can use the same method and rinse it the same
I’m going to do a video on micro channel soon as well!
@@diyhvacguy he's talking about the Trane spine finned coil here
Enjoyed your video.
I have a few questions.
Is the cleaning solution toxic?
How much dirty so you think is removed compared to just using tap water?
THANK YOU
I don’t think it’s considered toxic, but if you get concentrate on your skin it will burn. I got that all over my front lawn and it didn’t even kill the grass so it can’t be that bad.
@@diyhvacguy
Thank you!
Have great day
I've been using tap water for the past 20 years.... Twice or thrice a year.... Does the job perfectly well no need of any solutions unless you're living in a place that has too much oil in the air .
Am I doing anything wrong...I used Simple Green 3:1 dilution in a garden sprayer then rinsed off w water. The spray wand can direct the cleaner into the inside fins from the top openings in between the blades, so didn't bother opening the top.
No you’re golden 👊🏼
Have not cleaned my Window Unit in the 14yrs I had it. Just now it's starting to Not Blow Cold.. I Did and Do Clean the Filter Screen.
Would you recommend using a mild pressure washer to do it? One of those cheap 1000 psi types.
Only if you want to replace your coil. The fins are very thin aluminum and will flatten out so you’ll lose the airflow to the tubes. Use low pressure flowing water
@diyhvacguy what are condensers and foil made of? could a quick fix of using Easy-Off oven cleaner also work? ive used that to deep clean other items that have intricate parts, but im always leery of using on metals that may react to the cleaner.
Forgive my ignorance.....what is special about the dirt that builds up in AC coils vs regular dirt? Why wouldn't Dawn work?
You could have foamed from the inside of the unit as well since you had the top off and rinsed from inside out and then done it again from outside in.
I did a coat of cleaner on the inside as well. Not sure if I showed that or not. I thought I did 🤔
@@diyhvacguy Nope, you didn't...I was just about to come here to comment/ask why you hadn't also cleaned the inside coils as well...but Mark beat me to it 😉 Just found your channel...greats vids!
I wondered that too. I thought rinsing from the inside out was the way it was logically done, fact I thought it was the only way when you have it open and would start the chemical treatment there first.
@@diyhvacguy Many folks may not read these comments and realize that. You may want to do an edit and/or a redo. Good video anyway!
This why I always read the comments. I never just trust a video to learn how to do something. However the comments can also be wrong. Research Reseach and then make notes.@@The_Good_Life_starts_today
Can you show how to install a soft start unite?
Yes that video is coming out soon! Stay tuned!
also rinse from the inside out?
THANK YOU !!!
Would vinegar damage the aluminum?
Our A/C tech strongly urged me to stay away from using foam cleaner. He said he's seen air conditioners where other techs were using foam cleaner rust out the coils.However, he did say to use a garden hose a couple times per season.
