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.
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.
@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😮
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.
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
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.
Big thanks for demystifying my air conditioner. A few tools and now we can save a lot of money. I really appreciate the info.
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
Or you could just take your pump-up garden sprayer and fill that up with cleaning solution.
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.
This is good my guy 👏🏽👏🏽!! About to graduate hvac school in may
@Jhill I finished my HVAC school in July 2022
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.
Great videos! How about making on on cleaning the evaporator coils?
I find all you're videos helpful, Thank You.
Thank you so much 🙏🏻
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 ?
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.
will be doing this shortly.!
Nice i learn something new today i gonna put it in practice this summer thanks 😁
Thank You Sir, Appreciate the home warranty info...
Nice video !!! Very helpful
Just purchased the foam gun and detergent from you..... Great tutorial as i am out here in the dusty Arizona desert
looks easy enough and a cooler house is worth it!
Thank you for the advice
Great tips every time a tune in. Thanks🇺🇸 7:59
Great videos, done the right way..
Great advice. Thank you for this!
Good job, thank you
Looks good for the coil outside remember there is a second coil usually called an A coil inside the furnace that needs cleaning also .
Excellent Idea!!!
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!!
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.
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.
Thank you for this!
THANK YOU SIR , MUCH APPRECIATED 👍
Very helpful 👍👍👍👍
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.
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?
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.
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
This is especially important for mini splits. Even if it doeant look dirty, it probably is.
I have a Trane XL where the coils are mostly enclosed. Will I benefit from cleaning the coils like this?
You should do a video on the 100 different colors of coil cleaners....so many options......
Good idea! Thanks for the suggestions
You can also use a car wash foam cannon” which is the same syphon type can that make foam. About $29 on line.
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.
Nu calgon has a whole line of sprayers and sprays for different applications!
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
@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.
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 .
ive seen video using dawn soap. Does that work as well?
Any other recommended preventive maintenance I can do to a unit?
THANK YOU !!!
Thank you so much
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!
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.
Foam cleaner I use for tough neglected jobs, toilet brush works well and I bet you have an old one lying around!
Did you spray the Foam from both sides (inside & outside)? Thx
What is the blue liquid solution you use that's inside the bottle you use to spray
I really wonder how important it is to turn off the power before hosing everything down. When it rains, the unit is still running???????
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.
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
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 .
Thx!
Should you try to spray from the inside out?
Anyone know where to get replacement tips for these spray bottles?
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
Any videos on cleaning the insides coils in the home?
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
What detergent are you using and are safe for the fins? TIA!
I was wondering why you didn't spray from the inside of the unit going outward. Does it make a difference? On another note my son was in Utah for the UFC Fights a couple weeks ago. He and his wife love it up there. Great Video!
I thought the same. it makes sense to spray to oppose air flow. like vacuuming air filter from the outside. all the inbound particulate moves back the way it entered. aren't you driving particulates further into the coil spraying from the outside in?
Yes you should be spraying inside out. Blow the junk out the way it came in.
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?
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???
after replacing the fuse in a Lennox XC20 -48-230A01 I get a OU Inverter Communication Error code 434. Any suggestion?
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 👍🏼
Is this blue chemical safe to use regularly or just for heavy buildup ?
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.
Is it true that trane units recommend cleaning without any kind of cleaning solution?
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
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.
Thanks for the great videos! Do you have a video on doing a maintenance check on the unit? Checking refrigerant and regular maintenance. Don’t trust these companies that come out for $60. and end wanting to charge and arm and a leg additional work. Thanks!
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.
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
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.
My HVAC tech recommended just using straight water from my hose on the jet setting.
Yes if you do it regularly that would do the trick! It’s when it gets built up that you need the cleaner.
If you like corroded coils, listen to the guy that made this video. Use water
If you use JET SPRAY..... Always make sure you are spraying directly into the coil. If you spray at an " angel " you can bend the coils fins.
Can u use this on ur car’s condenser?
can you please do a video on ductless AC units?
Ive read and been told that these coil cleaners cause degradation of the metal fins of the outdoor unit, causing leaks. Im wondering if 409 spray cleaner would do the same thing less toxically.
It’s dependent on the ratio. If I did 3:1 it might have an impact but for most people a 10:1 ratio is fine and will not eat away any metal. Even at 3:1 that’s not true. Heck it didn’t even kill the grass I did this video on!
Can I use Dawn dishwash liquid?
@@Pearl3Drummer Simple Green would be a better choice, way less suds.🤙
Can we use a scrub brush or no?
This is something I had not even been thinking about!
We’ve lived here 12 years and have never done anything like this. The unit is the original unit (20+) years old.
Will doing this coil clean cause any issues since it is so old? I know that working on some other old items that doing so can sometimes cause problems.
Same situation lol.
Forgive my ignorance.....what is special about the dirt that builds up in AC coils vs regular dirt? Why wouldn't Dawn work?
also rinse from the inside out?
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
I cleaned my Goodman heat pump/air conditioner per your instructions. Everything was fine until I had to put the outer cover back on! 2 hours later, I finally got it back together. I consider myself pretty handy on getting things assembled but now wish I never had done the job. It wasn't even that dirty! Uuuuggghh!😢
So sorry! What was the issue? Some have a really stupid design that is hard to get the horizontal cover over the vertical cover. Sorry you had a rough time with it!
It was like putting a puzzle back together. There were 4 separate panels and you had to raise each panel into the other with 3 notches on each. The funny part is that this heat pump is 15 yrs old and will probably need replacement soon. I don't know if it was worth cleaning but I did it and now it's done. I love all of your helpful videos. Thanks for replying.
Yeah Goodman units are printed from rolls of sheet metal, and are sometimes a BIT*H putting them back together.
I started my air conditioner up today and I must say that it feels cooler! I guess all of the aggravation was worth it! Ha! Thank you😂❤
I used to work for a company that did a lot of home warranty work. The warranty companies are good. It's the service provider that gives them a bad name. If they wanted to they could have "hooked her up". My company took care of our customers.
I know someone has already said something similar, but you should be cleaning from the inside-out. Cleaning from the outside-in is just pushing that dirt on the surface deeper into the coil. You already had the fan off.
That’s a load of bologna. The dirt and dust goes down the fins to the bottom, you can literally see that happening in my video. I know of many hvac contractors that have always done it from the outside, and it works just as well. But if you want to do it from the inside there’s nothing wrong with that. I just don’t think it’s like a night and day difference one way or another.
@@diyhvacguyWithout soaking the electrical components, spray the AC unit from the inside out using a hose. After the initial rinse, use a coil cleaner that is compatible with the type of AC unit you have. Let the mixture sit on the condenser coils for 15 minutes before spraying the AC unit with a hose once again
@@WayneTesta4444 not sure what response you’re looking for with a comment that seems to ignore his clearly-stated perspective and experience.
@@westmcgee9320 If you find it hard to laugh at yourself, I would be happy to do it for you.”
@@diyhvacguy as someone who's been doing this professionally for now 7 years, i almost always do it from outside in on regular maintenance. I usually dont spray from inside out unless the coil is clearly impacted and needs real help. I dont ever use chemicals either but thats just me. Never have any issues.
I have a friend whose's AC service tech spray painted the aluminum fins of the unit. I asked him why he did that? He said his boss told him to do it. I asked him if he was going to spray paint his car's radiator? Or had he seen anyone else spray painting their radiators? I told him that was totally wrong! I told the tenant too! They both let it ride. Now they have to come out here every three norths to clean it. They are also charging the tenant for replacing the washable filters of the inside unit rather than just wash them as designed. Ugh! What do you think?
I have a new built home. How often should I hose down the 2 AC units outside? Also, is it best to do during the spring time/fall?
Believe me you will know! It will look dirty. I had a man come out to check my unit. I was so embarrassed to pay him $100 knowing my husband could have done this.
Right after the cottonwood flies. Cottonwood will be your biggest battle.
I am surprised that you did not spray any water into the inner chamber of the condenser fins. Why did you avoid spraying water into the inner chamber causing the water to pass through the condenser fins? Is it a bad idea to get water into that chamber?
Do you clean the inside coils with the detergent or only spray and clean the out side?
I show in another video what the middle of the two rows looks like and it’s not dirty whatsoever. I think doing it from the inside is ok but not mandatory. Especially not if you have two rows of coils.
