I am a licensed HVAC/refrigeration contractor. I think that this video is an excellent tutorial on how to clean the evaporator! Liked it!

I have "cleaned" my coils on several occasions. I never thought about sliding the entire assembly out of the duct work! I did even think it was possible without discharging the system. Thank you so much.

After doing 15,000 residential service calls, I can tell you that the vacuum is your best friend.

You gave me the courage to clean my coil. It took me about 5 hours just because I was extremely careful not to break or bend anything. My system is over 20 years old. It was not as bad as I thought but it was bad. Thanks for the detailed video.

A good idea would be to have a shop vac going while pulling out the dirt clogs, to catch the plume of dust. Also, if possible, if you seal around the filter's edge with painter's tape, you can almost completely eliminate bypass, keeping coils clean much longer.

Just pulled the cover off mine.. 17 years old and still clean.. Im a smoker and i had a large german shepard for 12 of those years.. i was surprised it was still pretty clean.. a little discolored brownish but overall clear of debris. Always keep my filter changed!

I had a local company in Jacksonville Florida called Waycoff's Heating & Air try to charge me $2100 to clean my coil. They also wanted $400 for their cheapest new thermostat. Then they told me I needed a new blower motor for $900 installed. All together they wanted $3400. When I bitched about the price, he tried to sell me a new unit. LOL I told them they were freaking NUTZ and to get out of my house. I asked around to all my friends if they new anybody that did a/c work. I guarantee somebody you know will know someone that does. I called the guy and told him where I got his name. He came out and did the coil cleaning for $400, the thermostat for $150 and he told me I didn't need a blower motor at all. Those technicians working for the bigger companies work on commission, so the repairs are overpriced and when you are in sticker shock, they try to sell you a new unit. Don't fall for it. Bunch of crooks.

This video is awesome. Our A/C was mostly inoperable. It wasn't able to cool the house anymore on hot days. Turns our filter didn't have a good seal and ton of pet fur got sucked up into the coil. We have 3 cats and big dog so it checks out. It was a hassle to get everything opened up but I was able to effectively clean the coil following your guide. Now our A/C is totally functional again. Thanks!

Good info, thanks. I checked filterbuy. Unfortunately, they do not list the static pressure drop (in inches of water column) that their filters cause. Filters are one of the most restrictive elements of an AC system. I switched from a MERV 11 - 1 inch filter to a 4 inch filter which had a low static pressure drop. My CFM at the return grill went from 980 to 1300. It was much quieter, as well, as there was less air friction. After cleaning the evaporator coils and straightening the return grill fins, my CFM is now up to 1750.

Thank you for this, I got quoted $360 plus $150 for the diagnosis of a dirty evap coil today. I gave him the $150 and told him I'd like to wait on the cleaning. Now I'm fixing to save myself some cash 😂

where your overflow shut off is, if you take the float off it and pour a cup of vinegar down that pipe that goes into your drain pain, once per month, you'll never have to worry about Alge buildup in your drain line again. Plus it keeps the drain pain clean of any alge growth.

This guy is destined to make a ton of $$$ Easy to watch and valuable knowledge shared. Go get em!!!! You deserve it

OMG..... Thank you so much. I did this today after a/c service guy wanted $1800 to do interior coil and outside unit. Wow, wow, wow. Perfect. ❤

Honestly I’m amazed we haven’t figured out a better design by now for heat exchange in our central air systems. I know there’re plenty of people out there that don’t even know they’re supposed to change a simple filter, but even from a serviceability perspective there’s got to be something…better.

Thanks very much for an excellent tutorial that takes the daunting cost of having someone diagnose an HVAC system and put it into proper perspective . Well done young man .

I am a homeowner and I've never known about this. I have lived in my home for 7 years now and when I bought it it was not in tip top shape. My house has been very musty smelling for the last month and I think this is my issue. Only thing is getting to the evap coils. It is almost unable to be removed like this, so I have my whole weekend set aside to tear into my a/c evap and condenser coil cleaning.... I'll bet they will make your look like it was spotless to begin with.. Thank you for the help on this. Got coil cleaner and a comb to get this done. Very helpful video, I owe you an adult beverage as you just helped me save a LOT of money.

Our HVAC system is 20yrs old, low on an expensive outdated coolant, and constantly freezing up, making summer grueling. We've been here 5 years, moved from a place where HVAC isn't common because the weather is nice, so we never knew it had to be cleaned, and nobody ever offered it to us. They tell us the whole system needs to be replaced for $9,000 which we can't afford and dont have enough credit for financing on. I'm not doubting the low coolant is the main issue but I do find it curious nobody told us the coil and compressor should be periodically cleaned. Since we can't afford to replace it, and thanks to coming across your videos, I'm now going to try cleaning both myself to at least reduce the hurdles in front of our poor crippled HVAC. I wouldn't be surprised if it helps a little.

I had no idea what an AC Evaporator Coil was before this video. Thanks for sharing.

Your a good man Charlie Brown! Best video I've seen to date, by far. Great presentation, detail oriented, with solid recommendations. Thank you & keep up the good work!
