Great work my friend! Making amercia great again ! Thank you.
Thank you so much 😊 great video
Always wear gloves when working around the fins. They are very sharp. There will be cuts without gloves. Happy cleaning and good video!
Coil comb kit
Can't you just vacuum all that crap out?
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 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.
As an HVAC self-employed contractor in So Tex, that is the reason the big boys have a fleet of new trucks whilst I, drive a 23-year-old mini-van with no AC. I just can't make myself charge that much for any repair or cleaning. I guess I'm old school or a fool or both!
@@livingyourbestlife711 Good for you. I'm sure your customers appreciate you and if they are anything like me, they'll recommend you to all of their friends. Stay COOL!! 😁
Do you have that guy's number who cleaned your coils. I live in Jacksonville Fl and that's what I need and that's all lol
@@franchise3531 Honestly, if I had it to do over, I might just try to do it myself. I'm sure there are plenty of videos on UA-cam on how to do it. Literally only took the guy about an hour for $400. It's not rocket science. Might save you even more money. But if you want to pay someone, I would start asking friends, family and coworkers if they know someone. Somebody will.
😂😂😂 I agree bro …They’ll finesse you. If you allow then too
After doing 15,000 residential service calls, I can tell you that the vacuum is your best friend.
That's the truth I would have put the vacuum on that mess first thing
Dog brush, vacuum and then the GARDEN HOSE on full blast.
A little messy but its LIKE NEW!
Whow
Toilet bowl brush 😉
@@fladave99 I would advise not using it on full blast if you have a micro channel coil.
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.
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.
Glad I could help!
Notice a difference?
Yes for sure. It cools much faster than before. Not only it cools faster, I notice the air flow is much stronger. Thanks again.
Update: for the last several summers my AC would run nonstop on hot days. After cleaning my coil it runs and cool down the house and shuts off. My condensate is noticeably much heavier than before.
@@tanman005 why
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.
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.
Shop vacs , duct tape , zip ties , man’s best friend !!
I stick foam sealing stripps where need in the filter channel and on the filter door/cover so that no air can bypass lthe filter
great idea!
That's a good tip about the painter's tape. The contractor who installed my unit when the house was built didn't even include a filter housing. The filter just lays diagonally in the duct. A real hack job. But using your tip could make it work better.
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.
This guy is destined to make a ton of $$$
Easy to watch and valuable knowledge shared.
Go get em!!!!
You deserve it
Thanks so much man. That means a lot to hear! Cheers
I hired him and he is worth his weight in gold!

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.
In my country, we have to clean evaporators once every 3 months as it's very dusty here. That's why we use split ACs which are easily serviceable.
This is a split system by definition. Do you mean mini split or ductless?
There is no reason we can''t create a marketplace standard for quick & easy access panels designed for the consumer to easily clean evaporator coils, but no. It gets far worse than this for many systems, and it all happens because governments aren't doing their job in creating proper serviceability standards. This could all have easily been corrected decades ago, but we ignore the problem year after year, expecting an industry to correct it for us which has zero interest in doing so.
@@uvhciM true, the problem is that from the consumer perspective it costs a lot of money to implement any of these changes, so it doesn’t happen quickly even once they are available. But that’s just it, they’re really not available at all, even today.
Like you say, it shouldn’t have been difficult 20+ years ago to design the newer generations of these coils to have some sort of access panels and drain systems to divert the runoff, or even change the typical straight vertical coil-over-fan so that there was a better layout in place for cleaning without fear of everything falling straight into your fan/electrics etc.
I will say a lot of the issue is that in a lot of cases the utility space is a huge limiting factor to the install that complicates things, in that the final product is hardly ever as nice or what you have in mind. Compromises have to be made. So it is difficult to produce a simple modular type system that will fit every scenario and work as intended, but I would definitely like to see some productive conveniences implemented that would make it easier for the tech and homeowner alike to service and maintain, as well as allow the systems to last longer.
I was watching a “pros don’t want you to know this secret” short about cleaning your condenser unit and it reminded me about my pet peeve with those too.
Back in the early 90s at least some of the units came with a fan guard that was removable *without removing the fan and motor assembly* from the top of the condenser. Why TF did they ever do away with that design that allowed for easy access to flushing the condenser from the inside out by any homeowner?? Or was the risk just too great that some idiot would forget to pull the breaker and chop their arm off… we’ve become either so reduced by the lowest common denominator or whatever saves the mfgr $.75 on the assembly line, one or the both, but either way it’s entirely fd us for decades now.
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!
Thats because all the crap is caught up in your furnaces secondary heat exchanger
@@marriagepartnersministry5942 Nope.. heating element and fan motor are clean also.
Hard to believe. But whatever.
@@Jackie-O.Louisiana I have no reason to lie to a bunch of strangers on youtube..Maybe its because i dont keep my house very cool or hot and turn it off when im at work.. Low usage i guess..
@@marriagepartnersministry5942 change your filter.
Great production...👍🏼 only two comments shop -VAC with proper attachment and a drill/w flex arm to hold screw or nut bits😊😅.
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 .
You are welcome!
what is so daunting about it? everyone has the knowledge oi the world in the palm of their hand today and that takes all the challenge out of it. The only thing an hvac technician will do that you cant do is work faster at a job. Anyone who does anything all the time gets good at it. Doing this the first time for anyone will just take longer but the results will be the same or , in most cases, even better than what you pay someone else who doesnt really gaf about your hvac system past the bill hes giving you.
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.
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. ❤
Awesome thanks for sharing!
@@diyhvacguy All my kids were shocked. I'm almost 70 years old and saved a ton of money. 👍
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!
Wow, thanks!
You made it look easy, I may give it a try. Thanks for posting a great instructional video.
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.
Great video! Super example on showing the pitfalls of no filter or leaky filter. Definitely a mixed bag on how accessible each installation's A-Coil will be. I was wanting to see a wet/dry shop vac in there somewhere, but ultimately your cleaning was all good. I guess coil access will determine if this can be done DIY or not. I also have a Bryant, but mine has a 4" filter box so that is a plus. Thanks for making the video.
A vacuum helps.
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!
Amazing. Thanks for sharing!
Great video! Your video gave me the knowledge I needed to do the job!!
I used the "remove the A-coil cover" method and left it inside the furnace. 9 screws to get the outside cover off and 8 more to take off the A-coil cover. It was remarkably clean given that it had NEVER been cleaned before in it 22 year life. I was expecting it to look a lot like yours did! There were about a dozen small dead insects stuck to it, so I used a brush attachment on our Dyson vacuum cleaner to remove them. I have a 1 inch filter that is hard to get in and out, but it must not leak very much. (2 years ago I forgot to change my filter for about a year. Not recommended, as the $850 blower motor died shortly thereafter.) I also vacuumed up about a dozen somewhat large dead spiders from the condensate drain pan.
I took a picture of it and tried to paste it in this comment so all could see, but I couldn't figure out how to do it.
Bet the airflow got much better! Nice How-To thanks!
Man, glad I bumped into this video. Never knew that evap coil had to be cleaned too! EEEK! My unit is around 4 or so years old and never did that. Sure am gonna do it now! It was hacked into my 1962 williamson furnace. Guy did a great job, but I can imagine it's not air tight to say the least.
Another great video for the DIY PEOPLE. I noticed you started spraying from the bottom up. Way to go.
Great video Dave! Going to do my sons when we visit him next month. His filter is not a good fit and going to see what I can do to improve that. Thanks again! Love your channel !
Thanks so much!
I had a large HEPA filter installed in the main collector before the evap. Simple access quick change. Last time I looked the evap looked like new. It was under 1000 bucks extra and worth every penny! Disgusting what gunk is in the air inside a house!
Ha! I was planning on cleaning my coil so great timing Dave!! Thank you! Cheers, George
You got it!!
I have done this a couple of times. I have found that on some of the hard to get to screws, or even most screws, you can just buy a roll of the silver metal tape to secure the
panels in place. next time all you need is a utility knife. seems to me a shop vac with a brush head would do a good job of cleaning the coils but the spray wouldn't hurt as well.
screws will almost always take a 1/4 or 5/16 socket. (1/4 in drive). Don't forget to put a towel or newspaper at the bottom to prevent all that crap from falling down into the furnace.
check the drain pan. Thanks for the good video.
Wow, thank you so much for a thorough and informative video! Excellent job!
My A coil is over 20 years old and is clean underneath. Using a pleated filter (not high merv, a merv 8 max) and having a proper system that forces all air to pass through that filter and not be missed is key.
You explain that well and thanks for showing how to clean and evaporator coil
Thanks for the reminder on Filter Buy, will write that number on the side of the furnace filter box for future reference. Great job showing us utubers how to clean a evaporator coil.
Make sure and use the Filterbuy link in the video description! Cheers
You've encouraged me to perform this task myself here at home ... and I bet the coils here are dirtier than yours! Thanks!
This video was helpful and great work you're doing with your channel in general.
At minimum, read the section with ***** (It may help a few people)
Great video to bring to our attention the need to service our HVAC which may decrease seasonal allergies and prevent an early HVAC demise. After watching, I anxiously took a vacuum, soft rubber (not foam) self-sealing 7/8" water pipe insulation, sissors and a hand swifter to the 2019 installed HVAC I have.
Although it's much more difficult to attempt to pull out the coils, I took a hard look at the intake, filter and HVAC surface areas anywhere I could reach. Everything in reach, including electronics, received some sort of vacuum/wipe down. The swifter picked up some fine dust somewhere in unseen corners. I'll leave the A frame coils alone for now.
***** To prevent dirty air from getting around your filter and into your HVAC.
As for the 7/8" soft rubber self-sealing water pipe insulation, I cut it straight up the middle (long way) so I had two long lengths, each with one sticky pull tape edge.
Measuring the length of the filter I cut two equal pieces of the insulation. I put the filter back in (a 5" thick filter) pushing it as close to the fan as possible leaving an intake side top and bottom gap between the filter and housing. Now I know where the cut half pieces of insulation are going to be placed and how. A trial run was performed prior to removing the sticky side cellophane protection.
Now pulling off a small length of sticky side cellophane I pressed each section into the area in front of the filter, (air intake side ONLY) top and bottom, so that the incoming air has nowhere to go but over the soft rubber insulation and through the filter. Since the rubber presses against the filter and the filter can still be easily replaced, I didn't need foam strips placed around my filters anymore.
Each 6ft length of soft rubber (not foam) self-sealing insulation was around $7 at Lowes. I only needed less than one for the job and it will last the life of my HVAC.
Great tip!
Goodness new entry on must do list ! Thanks for the help!
I had no idea what an AC Evaporator Coil was before this video. Thanks for sharing.
Same here, I'd heard of it, but didn't know what it looked like or that it was in the same airflow duct as the heat exchanger.
Bro I love your channel, one of the best if not the only HVAC channel, best wish!
Thanks so much! 🙏🏻
Thank you for recording and posting this valuable educational video.
Excellent video, great job explaining everything, thanks
My personal opinion. You are the best teacher Muchas Gracias. 👏👏👏👏👏👏👏
I get my filters from Filter Buy because of your videos. I do bulk and I also get my Refrigerator water filters. Great Job!
Thanks so much for the support! I appreciate you 👊🏼 cheers
2 gallon pump sprayer from the reverse side works pretty good too. Blows any chunks back the way they came. No chance of bending fins with low pressure. Garden hose on spay is just going to make an absolute mess. 1/8" foam tape on the filter frame on the side of the blower will form a tight seal once the blower sucks the filter tight with the filter frame. Not thick enough to cause problems pulling the filter in and out.
Bought a Steam Machine for just this reason. Figured I'd get at it with the shop vac as much as I could then then use the steamer to push any dust back from the direction it came. I'm hoping can access everything.
! ! ! You will blow/Wash them on to the heat exchanger and cause an extreme amount of damage,
Great video man. I tried this, but I didn’t know exactly what to do and the unit I have is a wall version. So I just had it switched out with a new one.
Excellent video! It gives me confidence to do my own🙂
I have a Klein tools Double ended ratchet, one side is one quarter and the other is 5/16s. Its slightly thicker than a quarter inch but isn't 5/16ths. If you're doing it for a living and don't have one all I can say is how? item number is 68200 just google it and you should find it. 1/4 side can also accept any screwdriver/impact bits and have a little more space and need to use your magnetic one for whatever reason.
This is the best video on this topic. Thank you!
My filter space is 4” too n what I do is use 4 1” old style filters n spray the lead one with furniture polish. I change out the leader n put a new one in back alternating the filters so they all eventually get replaced. Cheep n works well but the big key is the furniture polish on intake side of the lead filter. I only have to change filter every 6 months. Another way to tell if a-coil may b dirty is to check ur air supplies for debris around them. Also vacuum the cold air return grates n well around them !! A little time saves big bucks n a huge head ache later. Good vids by the way !!
I use to by cases of the no rinse evap cleaning for cleaning reheat coils in the hospital where I worked. Also used it on evaporator s on RTUs. For cooling coils on large fan units I bought some green cleaner that was non toxic and worked like a champ.
No-rinse evap cleaners should NEVER be used on reheat coils. The condensate from the evaporator is what allows you to use no-rinse cleaners, since that is what rinses the cleaner off. Please do not advise others to use no-rinse sprays in that manner.
No-rinse evap cleaner is ONLY for use in evaporators (cooling coils that produce condensate should be ok as well) and should only be used in humid or semi-humid conditions. It is a great product but needs to be used responsibly and correctly.
I’m a fan of using a shop vac when cleaning out stuff like that
Amazing video! My unit is rather new and I’ve only had one summer of AC use. This year it’s spewing out a barf moldy smell! From what I read. My coil needs cleaning. The installer is coming out tomorrow. I’ll see how techs want to clean. I’m skeptical he’ll do a thorough job but I’ll show him this video if need be! The right side panel I can open. Left side the panel is 1/3 in front and warps to left side. Not sure if will slide out. We shall find out!
How did it work out?
Thanks Dave for very informative videos, keep up the good work!
Thank you!
@@diyhvacguy great job explaining everything.
I was wondering in system like that and the air was downward would the need to get underneath the coils be needed?
My a coil is at the bottom of my furnace and air goes down, if the top is not very dirty it’s unlikely the bottom would be? Since the air is coming down on top of the a frame.
WOW this is unbelievable, thanks for sharing!
Just did my mothers house A frame, it’s a over 20 year old Lennox pulse air system and I think it’s never been cleaned. First having a a/c heat combination is something the installers told my father not to do. And I can definitely agree. The air volume isn’t enough the vents are located for heat so the A/C will run for hours. It’s an older house but I had the attic insulation redone and it did make a difference. I have the same size house but it’s a ranch with a separate A/C system and it is much more efficient and comfortable. So cleaning was a total pain can not get access like yours. If anyone is going to buy a setup like this knowing what it will take to maintain or repair things should be a huge consideration. Also when buying the no rinse cleaner I was concerned about when the heat would come on if there could be an issue with the cleaner used and fumes when heating. If anyone knows if this is a consideration let me know.
what is your seperate ac system? mini split through the wall?
Hey man great video. Will be doing this when the Georgia heat goes away because mine is in the attic!!
thank you for making this video, great job on the explanations!
Thanks! Just the video I needed right now!
Great information. Thank you for the video.
Just saved me $1500! THX so much! (and I used your link to buy filters) :)
Very well done informative video. Thanks for posting!
Thank you for a great video. I also ordered the comb with your link. Thanks again
Another good info video--thanks again😉
Excellent Video and great details!
Your channel has shown me so much I didn't know I could do!! THANK YOU !
Excellent vid! Thanks for airing your "dirty laundry"!
One of those jobs that you hate doing, but you hate it even more if it broke because of lack of maintenance.
Great job and excellent video tutorial!
PS, I probably would’ve used a vacuum cleaner (extremely carefully) with bristles and one of those 2 gallon sprayers that you get from the garden department. Because you can pump those with air and get a continuous stream.
Professional hvac tech here…please share this video as much as possible!! I love making easy money from diy’ers
Yea dude, share this with all your friends and family! 👊🏼
Thank you for a very useful tutorial. There is always an alternative use for service call $.
Excellent information, thanks!
You got it!
Great video. Retired commercial hvac tech.
Super job. Thanks
My breathing is labored just watching you clean that blanket of dirt off those coils. Wow! If that AC could speak, it'd be saying, "thank you, I can breathe again" What a satisfying feeling afterwards I bet.
Thank your so much for sharing your knowledge.
You can also use a small garden sprayer , I use 1 that's 1/2 gallon size, works well 😉
@diyhvacguy
Thank you very much for these great instructional videos.
I'm about to knock this out. We just bought and renovated this little country house. My HVAC closet is 3 sided. with a door on one of the sides. I'm going to make a separate access panels on one of the other 2 walls so I can access the coils more easily. I know your videos look easy when you do them. I've done some cleaning of this stuff before. It's not quite as easy as you make it look. Thanks for showing us the examples you provide.
I liked the video thank you for making it. I guess my question is since you had all that unfiltered air go by and did what it did. When you showing going to reinstall it and the heat exchanger was dirty looking why did you not clean that then? Yes there should be no big debris flying by getting clogged again but a wet rag or some wipes even and you could of cleaned that layer off and back tracked all the way back to the filter. I would think that your fan itself since that is in between everything it would be pretty dirty also and need some loving also.
Thank you so much for your very informative video.
Great video! Thank you for sharing.
Thanks for the tutorial. Would it be okay to use a shop vac on any of this? or would that damage the evaporator?
Thank you! This video was super helpful
Glad you found it helpful! Cheers
Good video. Hope you also installed a proper condensate trap and a drip leg for the gas supply!
how about the double wall 90 that is backwards and single wall into 2 double wall pipes
another great vid! it would have been interesting to see the air flow difference before and after! bet it made a huge difference.
You know it did. I'm surprised his A/C worked at all, probably froze up a lot.
Very good. Peels off like cleaning a dryer vent filter. I would think a shop vac would play a role at some point.
A big rectangular mixing tub (such is used for concrete, mortar, or drywall mud) might be useful to catch runoff.
If you want to rinse after you spray the foam a yard sprayer that you use for spraying weed killer or fertilizer or to spray roses works really good it has more pressure and you don't cramp up your hand from pulling the trigger so much. A one gallon sprayer is around 10.00. If you don't clean out your sprayer after each use you will have to give it a good cleaning so there is no residual Round Up or fertilizer. You might want to disconnect the hose and run warm water thru it from you utility or kitchen sink.
That was a great video. Thank you!
Excellent video! Thank you.
Would you do a video about all the different types of copper pipe and fittings (like annealed, hard, soft, when you can use plumbing copper instead, etc) for refrigerant lines and different ways to insulate them? Thank you!
Here's the vidoe: you can't. Ok give me 600k views
Thanx for showing me that.
Great video. Well thought out and perfect for a do-it-yourself homeowner.
I use a shop vac and a soft brush, and carefully vacuum all the good stuff up. I wish I could pull mine out the way you do yours. Maybe I'll take another look see if its possible, then I can use a wash and clean the outsides of the A coil as well.
Great video. Question: if I can't slide my coils out like you did, how do you clean the underside of the coil with the foam cleaner and water without the dirty stuff dripping into the furnace? Or is my only option to do a dry cleaning with a brush and vacuum? For the top of the coil there seems to be a drip pan around the perimeter so that a foam cleaner can be used and it collects the dirty water and out the PVC pipe? Is that correct?
Great very professional
Good video. Sometimes if it's bad enough, you have to just pump it down and pull the coil, take it to the yard and wash it out. That's always fun (sarcasm engage). Reinstall, braze her up and pull a vacuum, open valves, rock n roll.
great video thanks
when i bought my house, i needed the furnace and ac replaced. they were 40 years old. i was amazed that the evap coils looked very good. the previous owner must have religiously changed filters all those years. the new system uses merv11 5 inch pleated filters in a well sealed box so im hoping ill never have to clean the coil, the lines would have to be cut.
dude , love your videos TY ,
Thank you for showing me the air conditioner company they want to replace the whole system but I did it your way it got so cold my kids started complaining it's too cold in house
