How To DEEP Clean Your AC Coils FOR FREE. Use This Secret Sauce

[@nectros7157]

I see lots of videos about condenser cleaning, but very few about evaporator cleaning. Is it as important to clean the evaporator as it is the condenser coils?

[@diyhvacguy]

Yes! I have a separate video on evaporator coil cleaning 👍🏼 check it out!

Only problem is your evaporator is most often in a 125 degree attic. Not something you want to touch in the middle of the summer...

[@dedicated2WHOiLove]

10/4 dude. my mom thinks i'm a dufus and will tear her units up, so i'll have to wait for her to go on her Europe trip in three weeks to do this. i know she needs this done because i went to mom's to mow her yard and the service guy was there and totally blew-off this service. the units have maybe 2 inches of crud in the pan, and the dude only did a cursory hosing from the outside. the fact is the units were past warranty in mid 2019 and the hvac company is anxious to replace them. i know this because they used to flip the fan up any do all this you just demonstrated. i also know this because my nephew quit hvac because he was under pressure to help old units fail. it's a hustle out there in the wild to be sure.

[@freespirit1975]

The main thing I have found is to make sure your AC is not running when you cut grass anywhere near it-like 20 feet. Also, if your neighbor's yard comes within that distance to your condenser unit, watch them, and shut it off when they mow that strip of their lawn (if you are at home of course). If I drilled holes in the floor of the condenser I would shoot a little shot of Rustoleum paint in the hole to keep the bare steel from rusting immediately.

[@peterrudy9207]

Maybe fabricate some cover from plywood , heavy cardboard or sheets of plastic ?

[@jere4524]

Great information. Thank You. I"ve subscribed! I am planning to use Simple Green HD which is actually purple, and it is advertised not to have any bad effects on metals. I used it once before in an ultrasonic bath to clean a carburetor, and it worked great. A suggested dilution is 1 cup of the purple cleaner with three cups of water. I'll try to remember to post my results later.

[@frandanco6289]

I can't remember where I read this , but I think I read once that Simple Green was bad to use on Aluminum.... It causes a reaction with the metal... I hope it was a nightmare or something...

[@rodfroelich5908]

Best cleaning ive ever seen. But one thing id recommend is to vacuum inside the unit when dry to remove DRY debris before wetting inside the unit. So much easier to remove dry than wet debris.

[@Butterfly-iz3nm]

Funny thing is I learned to clean the ac coils as a kid watching my mom do it. There was nobody in the family with any HVAC experience either. My mom just used to give the ac a "bath" as she was doing a semi-annual spray down of the aliminum siding and the awnings keeping the house clean. She took great pride in being a "housewife and homemaker". You don't see or hear that anymore nowadays from anyone.

[@diyhvacguy]

That’s awesome. Thanks for sharing! She sounds like an awesome lady 😎

That's because the people that run the world didn't care for the close knit families in America.

[@bbhoustontx]

@@rubylusmom are you taken?😊

[@mooreadventures]

I think it is worth mentioning that you should NOT use a strong water stream (like "Jet" on many nozzles) as that can actually bend the fins (speaking from experience 😥). Also I recommend to wear gloves as those fins can easily slice your fingers if you are not careful (also from experience). Thank you for the video - I have to try the Dawn/Vinegar solution 👍

[@piezoman79]

Great video 👍🏻 Only thing I might mention is regarding drilling larger holes in the bottom - be careful that you’re not inadvertently creating entrances that weren’t available previously for rodents or other pests to take up shelter and potentially wreaking havoc in other ways to the unit

[@HeavensRaptor]

If you get ambitious enough to drill a hole, might as well add a drain nozzle that you can cap and uncap for this. That would help.

[@pantherplatform]

Wreaking HVAC lol

[@keatz85]

If they can fit through those small holes, I'm assuming they can fit through the top (fan vent). My unit has several drain holes as manufactured so can't be too bad.

[@keatz85]

@@HeavensRaptor I think the purpose is to drain year round, not just once.

[@piezoman79]

@@keatz85 I don’t know about yours but the holes on the bottom of mine are more like ‘weep’ holes than anything for allowing debris to pass through, so any leaves or other biomatter that collects just becomes a breeding ground in there

[@longjohn526]

On that Fridgidaire unit or others with the louvred covers like that I always trained apprentices to clean that matting off the coil before applying your chemicals. Either spray it off or take a furnace brush and remove it first and then spray on your chemicals. That way you get better penetration. You want your foaming cleaners to push as much gunk as possible to the outside and if there is a layer of matting on it that can't happen nor is penetration as good. Another thigs if you live in an area with a lot of cottonwood trees such as close to a river then don't clean the condenser coils until after cottonwoods have released their seeds or you'll just end up doing it twice or worse end up with a plugged unit after you already cleaned it. Cottonwoods are the worst and cling like crazy when wet so there I'd recommend dry brushing it first with a furnace brush

[@diyhvacguy]

Thanks for the tips!!

[@jackmclane1826]

I had best results when I first flush most of the gunk out with a fairly concentrated jet of water from the line. No pressure washer as it kills the fine lamella. THEN apply some detergend and then flush again. This is why I get most of my stuff for free. People with too much money throwing out stuff that needs just minor maintenance, sometimes only cleaning. Started with it out of necessity during college as I didn't have the money. But now it has become kind of a hobby. The best score of the last year was a 5 year old Miele dryer (Top of the line ~2000 bucks German made appliance). It just needed the air ducts cleaned.

[@bridgettarvin5626]

Yeah I see nice appliances etc given away free that are literally SOOOO easy and cheap to fix! But “easy fix” is subjective…some people just truly would rather save the hassle and time of diy’ing “anything” and have the money to go out and buy new things! But that’s ok bc it sure helps the people who ARE willing to fix it and know how save a lot of money that they NEED for other things. I guess in the end it all works out! Me personally tho-it’s not just the money… I find the more I roll up my sleeves and figure out how things work, the more knowledgeable and confident I become to at least try -or at the very least, if I HAVE to hire a technician, I kinda have “a clue” what they’re talking about and I don’t feel scammed or bs’d…

I think I will try vacuuming the dirt and leaves out from the interior floor pan before getting things wet. If I drilled some drainage holes I would let them dry then paint or coat them so they will not rust at the now bare metal..

[@az8theist977]

Shop vac out the dead leaves BEFORE soaking the coils? While they're still dry? IDK, just a thought.....

[@DOLRED]

If your AC unit is near trees, count on lots of debris drawn into the coils each season. I have a large shady Linden tree near my unit and the tree spews all kinds of stuff. The tree is great in shading the AC unit but then compels me to clean the AC coils often. My Brother in Law has no trees nearby and his unit stays in better shape. Trees also release micro pollen which is very dirty because it not much more than dust in the air.

[@paulcrescenti5581]

Nice video. Great info on using that stiff cleaning brush for resetting folded/dented condenser fins. I live in the desert, so there is little maintenance required, but the key is just making a schedule to periodically take a good look at the outside unit. Pretty much everything you maintenance in this video is easily detected by simply taking a good look at the unit. If it has junk inside (I get a few leaves from a nearby hedge), open it up and vacuum it out. Junk on the coils, wash them out. You will reduce energy consumption and keep your condenser unit clean and happy.

[@Alex-Zone]

Okay Paul I got the leaves from the neighbor's tree last night while they were sleeping, where do I put them?

[@dand3975]

Thank you for the detailed AC oil cleaning video. This is on my spring yard work To Do list. Will stay tuned for the evaporator coil cleaning video. Nice trick for streigntening those aluminun cooling fins.

GOLDEN info. Thanks so much! I have my heat pump A/C unit checked out twice a year. I almost always observe the tech. without becoming a nuisance. YES, a rare tech is very through, but more times than not, mediocre at best. I have 2 Goodmans, one on each end of our home. Your SPOT ON about expense for doing proactive maintenance. I do believe doing YOUR OWN cleaning twice a year is wise and will save many, many hundreds of $'s! After watching your two videos, doing the condensing and evaporator units yourself is very doable!! THANKS!!

[@troyporter3825]

THanks for this! I have a question. I was able to clean my condenser using your video, but it was hell because the wires that connect to the fan are SUPER short ..i can only tilt the cover up slightly, so i had to use one hand to do that the whole time!. Is it easy to disconnect the wires from the fan ?

[@diyhvacguy]

It’s not too bad. Three wires. Just snap some pictures and you’ll be good to take them off and reinstall 👍🏼

[@wraith313]

Is there a reason you didn't clean out all the dry debris on the inside first? I'm having an anxiety attack thinking about those dry leaves becoming wet and soggy when they would have been so easy to remove before

[@amerlin388]

I don't see the value of having a specific tool for foaming A/C coils. Any tank sprayer or in-line garden hose (low pressure) foam 'cannon' should be sufficient. They make cheap tools specifically for straitening heat exchanger fins -- I think you actually show how to use these in another video.

[@Draza17]

I use a low pressure steam wand with vinegar and all purpose mixed in the tank, then spray just steam to clear rinse any residual that may remain.

[@fishandgameman]

I use a solution of this diluted pink liquid that I can’t remember the name of right now, but it contains hydrofluoric acid. After I get the bulk of debris off the coil, I use a spray bottle and apply it to the wet coil, let it work for about 15 - 30 seconds and rinse thoroughly. It does an amazing job and the coil shines bright when done. The pink stuff is sold for this purpose, but does an amazing job cleaning and brightening my aluminum trailer too. You have to be very careful and avoid getting the full strength cleaner anywhere on you. Hydrofluoric acid has an affinity for calcium. Don’t take a bath in it and you will be fine. 😂

[@Joe-qw6il]

Each season around may, before it gets hot, I remove the top part the way you did, then I clean it thoroughly with compressed air from my air compressor, then after I’ve gotten all the dust and cobwebs out, I follow it up with my water hose and a good nozzle, don’t think I can get it cleaner than that, thanks for the demonstration

[@jhenniceamorrow5936]

Thank you, so much. The information you've shared has enabled us to afford repairs. Very much appreciated!

[@Ryarios]

2 tips: 1. Don’t pull the disconnect when the unit is running. Turn the thermostat up so the unit shuts down and then pull it. 2. Don’t spray the coils until the unit’s been off of 15 minutes or so. They can get quite warm when running and the cold water from the hose on hot coils can cause problems eventually.

[@Korruptor711]

Thanks for this video... the timing is perfect. I just replaced the contactor and capacitor (contactor seized) and cleaning it is next on my list.

[@chrisbelsito4231]

Quick question. Would it be better to take a shop vac and get the heavy dust off first?

[@diyhvacguy]

Yes you could definitely do that.

[@binnsbrian]

I can't believe how much I've learned from your channel. Thank you. Do you have specific ratios of water , vinegar and dawn soap?

[@diyhvacguy]

Awesome! The ratios aren’t super important. Probably a teaspoon of soap, 1/4 cup of vinegar and the rest water. 👍🏼

[@SolidOrangePaw]

Vinegar is an acid. Dawn is a base (soap). When you mix the two they neutralize each other (basic high school chemistry). How much each is neutralized depends on the mix and concentration of each. Vinegar can be used in laundry as a rinse aid to neutralize any non-rinsed laundry detergent so your clothes don't attract dirt due to any soap residue. If you have mineral or calcium deposits, the vinegar can help dissolve those because they are a base. I could see applying vinegar, rinsing, then applying soap, but I can't see the effectiveness of mixing vinegar and soap together unless you want them to neutralize each other.

[@MISTERLeSkid]

Why would you not first vacuum / brush the worst of the crud off while everything is still dry???? As soon as you wet that crud, it becomes muddy and that alone will cause it to adhere much more. If you remove the worst of it, then the shampoo will be more effective, to boot.

[@dukebeach1]

I was thinking the same thing. Much easier to get out dry particles that way and anything else you can then do the wet cleaner and rinse. Maybe there is something I’m missing? Wouldn’t be the first time.

[@LauraZeller-oy3ye]

For my indoor tray I found rust b/c it was never cleaned or indicated to be checked. It made me wonder why a water collection overflow tray was not painted with rust resistant paint? It would be a good to prevent rust on the bottom of the outdoor unit tray as well.

[@ianbelletti6241]

One word of warning: if you live in a high corrosive environment such as near the ocean any chemical wash will remove the anticorrosion chemicals on the coils. Many tradesmen in high corrosive areas will recommend favoring a water only wash whenever possible.

[@mikehughes8]

Yeah I wash mine with water too , to keep corrosion down, but I would imagine if it gets too nasty you would have to use something , milder the better 👌 you can sure see the anti corrosion film on some

[@carlmoore4518]

In regard to cleaning the condenser unit, can this be done during the day when the compressor unit is hot; or should it be turned off for a period of time to cool before a DIY cleaning? I can't imagine cool hose water hitting a hot unit being a good situation. Thanks.

[@hotrodray6802]

Running it sucks in ambient air across the hot coils.

[@rkgsd]

Interesting that you see some pros rinsing from the outside saying inside out isn't necessary.

[@mattm3901]

It may not be necessary, but it’s much easier. The normal operation of the updraft fan pulls in debris from the outside in, so it’s easier to clean by pushing it back from the inside out. If you spray from the outside in, you may be getting more debris into the coils than you need to.

[@rkgsd]

I just cleaned mine. I rent, and it's a really nice place, but the new property owners won't do anything here. I decided to not ask them to do it, and just clean it myself. I've lived here for probably 4 years, and it has never been done. Fortunately, I only had the single coil so it made it a lot easier. There was not a single spot where air could come through. It was a 1/4" thick mat of dirt, dust, and who knows what. I didn't even use the detergent stuff. I bought it last fall, but don't know what I did with it. Water seems to have been enough. Before I cleaned it, the temperature at the vent closest to the furnace was 58° F, and the return was 70°. This is after it had been running all night. After, the temp at the vent closest to the furnace was 50°, and the return was 72°. That was after running for about an hour. On hot days, I couldn't even get the temperature below 76° with it running nonstop (it wasn't like that prior to this year). Now, I just need to get some foam to go around the tubing between the unit and the building because it is gone. That should make a bit more of a difference.

I actually have a story RE dirty evaporators. Back in late 70's, the Army's Fire direction computers (artillery) were large units that fit in a van on back of 5 ton truck. Chief called me, told me I was going to Fort Irwin - Mohave Desert. The weather is actually very nice in daytime in January. Long story short, the A/C filter was bolted on, was not cleaned often enough. Even a high in low 70's was enough to cause trouble. They swapped power supplies around while trying to fix. They all fit, but were not compatible. Did no harm other than being unready. Operators instructed to clean filters.

How do I clean a minisplit on a balcony? Mine gets clogged with cottonwood fluff every few weeks and the efficiency drops a ton. Self-cleaning mode isn't strong enough to dislodge it, so I've had to try to pick the fluff off the coil with my fingers. Every video I can find about cleaning them involves water hoses, which don't exist on a highrise balcony! There's not a lot of room between the coils and the wall, and a metal grid on top of the coil makes it hard to get at. Surely I'm not the only one with a highrise balcony minisplit near cottonwood?

First, it's going to alter the airflow which is supposed to go through the coils but now will start sucking the air from the bottom thus reducing the volume that goes through the coils. Second, the air being sucked through these holes is going to bring dust and dirt from the bottom inside the unit. Both of these effects could be negligible, though, just don't turn the bottom of your unit into a pasta strainer. It may also be a good idea to plug the holes that you've made with some sort of rubber or plastic caps and only open them while you're cleaning the unit.

Great info for sure. I need to do both my units. Im good with the homemade solution. However, will simple green work as well?

Rinse it well. It hard on aluminum. We don't use it on airplanes.

I rinse mine with water and a shop vac once a year , it's easy maintenance if you already do a bunch of house maintenance yourself

[@kyle2kmaxima]

is that coil gun specifically to be used on a garden hose with some adapters?? i have a foaming gun that has quick connect but it's for a power washer.... same thing with different connections? or do i need a coil gun too besides my foaming gun?

What do you think about sunbelt coil blaster cleaner? it's suposed to be "zinc" safe.

[@gweedomurray9923]

I would do a straight rinse first, to remove the "easy" stuff, before doing the soap treatment. I like the tip on rinsing a double coil setup so that you don't drive the grunge deeper in.

[@fritzkabeano1969]

Why wouldn't you just use a shop vac first to clean off the coils since you'd need the vac to clean up inside the unit? Then deep clean it with the solution.

That actually would have been smart! Noted for the next one that has a sheet of junk on it! Thanks man.

That’s what I was going to say. I always start by propping up the fan and vacuuming out the leaves on the bottom first. If the condenser coil is dirty enough, then I will put a brush attachment on to the wet vac and vacuum the coil before I get it wet.

My outdoor AC coil fins looks like some area is disintegrating. Turning into like powder substance. What’s going on with that??

Double coils #$(*&(*. I lift the top off and use my leaf blower from the inside out. Hail dents and damage is no fun either.
