[@DisabilityExams]

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.

[@stevepape9011]

[@rael5469]

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.

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.

[@claude77573]

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.

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.

[@Chopper153]

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.

[@borshardsd]

This is a split system by definition. Do you mean mini split or ductless?

[@uvhciM]

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.

[@piezoman79]

@@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.

[@piezoman79]

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.

[@kickassclone75]

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.

[@geezerhull]

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.

[@SpaceCadet4Jesus]

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 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.

[@bigd3104]

​@@johnnybhoy4278Exactly what I was thinking too. I'd be nervous even pulling the A coil out of the plenum to clean it even if there was play in the line set tubing. Too much of a chance to cause a leak at the connections, in my humble opinion. Which sounds like what happened here.

[@BearHomeOwnerDIY]

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.

[@Jibberish18]

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.

[@ronbishop5609]

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.

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.

[@danwake4431]

[@scottwebber652]

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 !!

[@StillOnTrack]

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 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.

[@amedaius8492]

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.

[@travistalkington9297]

For water I use one of those pump sprayers you can get from homedepot. Allows you to get a good constant flow of water for rinsing

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!

Before you do this, find where the water drains outside your house and hook your vacuum to the pipe to clear the clog and drain the water. After I crawled into the attic and got into the condenser, I found that it was pretty clean already. I could’ve probably skipped all of that for now.

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

[@michaelcinaz]

Nice job. 👍 I thoroughly clean my condenser coil every couple of years, but I don’t see a way to clean my A coil box up in my attic. It’s completely sealed with no access door. I have a Lennox, horizontal installation. It cost me $1500 to replace the leaky coil box 6 years ago. The old coil box lasted 7 years before it started leaking. If it costs $500-$1000 just to clean it, I might as well just install a brand new one for $1500, if I start to have problems. I use Merv 8 filters and change them on time every time, so the coil box should not be very dirty, but who knows.

[@billmurphy1335]

there not 1500 no more. ac parts have gone way up

[@roscoetanner5996]

The manufacturers would rather replace the coil rather than have it cleaned or repaired. It's all about the $$$ for the tech and the manufacturer. LOL

[@billmurphy1335]

you have to cut into the sheet metal

[@blipblop92]

​​@@roscoetanner5996 correct. Easy to overcharge on parts then on human labor. Nobody wants to pay a guy $200/hr while they make $30/hr

[@Vortechtral]

I had a guy in last year because my condenser was icing up. They said we have a small leak, so they topped it off, then said it will only last that summer max before we have to get it topped off again or start replacing stuff. They never went inside and looked at the A coil or anything, just eye balled the condenser and that was it. The reason it was icing, well the main reason, maybe it was a bit low on coolant? was my A coil was clogged with dust and couldn't breathe. Ice was on the top side of the A coil, there is a spot cut out as an access hatch to see one top side of the coil. The next day I pulled the other "hatch" off which is to access the bottom of the coil and vacuumed out the huge amount of dirt, hair, debris, etc. This all stopped the actual cooling of the house. Don't always throw large amounts of money at things when you can look at it, and do something simple and save yourself a lot of headaches. Your coil wont be completely sealed away, as they had to install it. At the very least, you know where it is via the copper and PVC lines going in the unit. Those lines are all usually in the same spot, so you can see where the video posters lines are and know roughly where to start. Then go to the side and cut a hole in your furnace, make sure you have a spare piece of sheet metal that is bigger then the hole you cut. Then you can at least clean the bottom like I do, and it will make a HEAP of difference. After you are done cleaning, screw the new sheet metal panel up, then use aluminum tape to seal it all up and you're done.

Good job man, mine was not neglect, it was a poor filter design from the start.

[@EricN73158]

I highly recommend using a dust mask and some eye protection maybe even a full face shield. Also disconnect power, you want to be safe.

[@mikeglasgow9618]

Another great video for the DIY PEOPLE. I noticed you started spraying from the bottom up. Way to go.

[@tommywatterson5276]

This coil looks like it had a filter problem. You had said your filter wasn't sealing very well ? I've just never seen an EVAP coil with this kind of dust all over it. You did a good job cleaning it as it certainly needed it. I've only heard of cleaning the condenser coil outside if it's exposed to dusty conditions. I've even cut my unit off before while cutting grass etc with lawn mower around the unit so it wouldn't suck dust and dirt into the fins while running.

[@diyhvacguy]

Yea that’s a good practice to turn it off while mowing around that area. I’ve seen coils this dirty, but I didn’t suspect my own coil that’s 3 years old to be this bad. Yes it was a filter issue for sure. Now that it has a nicely sealed Honeywell it will never get remotely close to getting that dirty. Cheers

[@Perly53]

I bought a house in Florida while I was still out of state. I had an a/c company do maintenance every 6 months for 2 years. Also, I needed a gardener to mow the front/back yard because the tenant was a busy single Mom. Anyway, when I moved into the home, the condenser coil was just totally stuffed with grass clippings, dirt, etc. The unit running while a big riding mower cutting the grass was the cause. Now, after I got it cleaned out, I like you, turn it off and I use a push mower around the unit to keep it clean.

[@danwake4431]

i thought i was the only one who turned off the ac when mowing! lol nice to see like minded people.

[@amerlin388]

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.

[@NahtShure]

That's wild! If yours is that dirty, mine has to be worse. I'm gonna dig into mine tomorrow. Thanks for the video!

[@nikcook2340]

Good video! I would put a disclaimer on this though. On the majority of systems I see in the south/southwest, that coil isn't sliding out without cutting the lineset.

[@diyhvacguy]

Yes there is one in every video description 👍🏼

[@DJV94022]

I did this last week..its just like getting mud off a truck..first you rinse it then you brush it..same thing here just wear a cheap full head mask plus safety glasses a coil comb and a vacuum and itll be the best out come just good luck to you next morning and rest of the week cause your neck is ganna be hurting 😂😂

[@RebeccaBarnett-c8j]

I get them from Amazon monthly so I remember to change them. I saw a video where the guy used a garden sprayer to rinse and vinegar and water to clean, instead of coil cleaner. I thought that garden sprayer idea was great.

[@cloudyskyforever2553]

Dear Dave, first and foremost, thank you so very much for making these amazing video that are helping so many new DYIer people like myself to be able to diagnose and fix things ourselves. I just found out that you live in the beautiful state of Utah and so do I. After this video, I ran down to the basement and found out that the HVAC system that I have is slightly different from the one being shown in this video. My home was built in 2020 so I'm not sure if that makes a huge difference but it looks like, for my case, they use the two large in diameter PVC pipes for the exhaust and return that are located right in front of the evaporator coil assembly. I'm not sure if there's way for me to slide the coil assembly out without having to remove the PVC pipes. Also, I think the system that I have called "up flow" where the evaporator coil assembly is located on top of the furnace assembly. I hope you will make a how to video like this one but for newer system. Thank you again and you just earned another subscriber :)

[@diyhvacguy]

Hello there! Unfortunately if the pvc intake and exhaust pipes are right in the way, they’d need to be removed. Some furnaces are definitely not made with cleaning the coil in mind. But the pvc pipes can be cut and a coupler can be used. Sometimes the intake is not glued in place but you’d just have to see how your furnace is done. I’m sure I will do another Evap coil cleaning video soon so I’ll try and make that with a high efficiency furnace with the pvc tubes 👍🏼 cheers

​@@diyhvacguySame problem I have. My 90% furnace has the PVC exhaust/intake pipes. It's only a year old, but someday I'll have to contend with this problem more than likely. Thank you for all your helpful videos!! Much appreciated!!

[@mcoguyaj]

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.

[@danpeppers5564]

another great vid! it would have been interesting to see the air flow difference before and after! bet it made a huge difference.

[@jeffbloomquist7925]

You know it did. I'm surprised his A/C worked at all, probably froze up a lot.

[@drivethrupoet]

Thanks for this! I'm now angry that all the A/C people that have come out over the past few years have never offered this service. I've got an old system on life support, yes it's time to be replaced but it's not dead yet, but the A/C folks only deal with the external unit cleaning. I KNOW it's gotta be nasty in there.

[@mxcollin95]

Pro Tip: After 17k service calls, I like to take a swig of the brown coil runoff water during my first coil cleaning of the day. I find that it really wakes you up and all the microbes, dust and dead skin cells add up to a lot of protein and minerals and really makes you feel alive!

[@petruse8893]

As usually-outstanding quality in presentation and showing the way to solve a lot of AC related problems.Sadly, there are some issues which cannot be solved.Algae growing in and on your evaporator are nor possible to get rid of ( not pan growth,this is easy). Any algae killer gets washed away immediately after running the unit for 15 minutes.Sure, the old patch is dead,takes about 1 week until a slimy growth starts creeping up the fins again.Dismantling the unit every 7-8 days seems to me a bit tedious

Spray some lysol into one of your intake vents.

There are tablets for algae that can be placed in the condensate drain pan that slowly dissolve over time. Should last at least one season.

My late 60's Lennox is in a tight closet filter 14×18x1... been freezing up no air getting past it... as far as I know it's never been cleaned... I cleaned the 25+ yr old Compressor coil for the first time a few weeks ago... back in 1984 dad was sick and a family friend looked at it coz it was running hot and cold at the same time... so he asked my mom do you want hot or cold? She said cold so he disconnected the electric heater coil... and had gas heater installed in the kitchen... been yellowing the paint ever since

[@TheWilferch]

Forget about better quality 1" thick filters. Something that over-rides and trumps ALL 1" filters........is to use a DEEP PLEAT filter that is 2" to 5" thick....and it is constructed with a FLANGE arround the edges to fit the 1" thick opening recess.... BUT has 4 " more filtration hanging out the backside into the ductwork behind. . Consider......a 5" pleat is NOT a 5" thick filter that would cause more pressure drop.....it is 5" thick but PLEATED, so the surface area is greatly increased to give more filter area for less pressure drop and also more cleaning action. It's the best of both worlds when targeting better filtration AND low pressure drop. Here is an example....not necessarily this brand but this style.---> kzbin.info/www/bejne/Zmi9n6yJqZ2lfqc. I buy another brand (Filter Buy)....but use blue painters tape around the edges instead of having this rubber gasket, to assure no by-pass losses. Here's another-->kzbin.info/www/bejne/hKamqH6cbLh1mKs

@@TheWilferch it’s in ceiling so I can’t just add thicker one but I’ll def do the painters tape trick thanks for tip

[@TheWilferch]

@@Turtle-sz7sk ......you CAN add a thicker one to the ceiling location. Mine is in the ceiling too. Doesn't matter if the standard 1 " thick filter housing is on the wall or ceiling....the important part is if there is space enough in the ductwork behind the filter housing. I had to remove some firm insulation from the tunnel shaft ductwork walls behind the filter for a few inches.... to accommodate the thicker filters. Ceiling mount vs wall mount is irrelevant.

[@Turtle-sz7sk]

@@TheWilferch huh I’ll have to look into it. Would def needs some modifications.

[@TheWilferch]

@@Turtle-sz7sk ...for most folks there are no mods required...if the space BEHIND the housing accommondates a thicker filter. In my case, they built the ductwork tunnel behind the filter with rigid foam insulation on all 4 walls of the ductwork....so I had to slice-away a 4-5" depth behind the filter housing to fit my 5" deep filter. Many don't need to do this. Look at the links again.

Why not vacuum the coils after the combing of the excessive dirt? Suggestion : I’m no way a A/ C tech and I live in a very small town in Mexico.

I feel some coughing coming, thankfully the last time I cleaned mine out it wasn't to bad and I just vacuumed the dust and drainage tray out.
