I know I'm late . I've did heating and air for 17 yrs .I did commercial , residential , and industrial work. It's really hot but pays good .now I do it for myself .
Don't forget about the coils in the outside unit. I mix water and a little dish soap in a spray bottle. I douse the coils good from each side, then use the garden hose on low pressure to rinse it out until I can no loner see any suds. Never use high pressure on the coils, they bend easily. It's surprising how dirty those coils get and how much better the system works when they are clean.
Oh come on that wasn’t to bad. Now try it in an attic in July laying on your side. As the customer keeps asking what’s taking so long and are you sure you know what your doing. Absolutely infuriating
I have used a product called Simple Green to clean the fins and coils works ok with a fin comb and soft brush. The stuff is biodegradable and not hard on your lungs. Always wear eye and glove protection.
I ain't no technician but the products are corrosive and can damage the unit if is not removed properly. I suggest to put some sort of plastic cover and a shopvac and use more water
doing the top is pointless spray from bottom and rinse from top, its says you don't need to but trust me a tech of 23 years, just make sure your pan is clean or you have a shop vac on PVC drain
Ray you did your bed with what you had now this is the important thing to do with your ac clean it every three months or or less keep the filters clean by changing them often😜. Need anymore advice please don’t hesitate to ask have s good day
My HVAC man sad to use "2 of the mesh filters" instead of one of the pleated filters because there is less resistance to air flow and by doubling the mesh filters, you will generally catch what needs to be filter away from evaporator coils. As cheap as mesh is, replace monthly at a total of $5.00 for two. Clean all coils with quality coil cleaner the beginning and end of summer.
garden hose and a pump up sprayer . i went to tech school 1972 worked for tran a/c and hussmann ref until 2019 , clean your drain pain of dirt or all that trash will stop up the drain. change the filter once a month and use a good filter not those cheap ass 4.00 filters .wash the condenser also put your hand on the liq line is it hot
Idea…if the filter got sucked in…simple roll of pipe strapping…the stuff full of holes you hold pipes up with…screwed to the center from top to bottom so the filter sits against it and it can't get sucked in. Just an idea that came to me to suggest. Also, trash bags, duct tape and hang it on the inside, wet dry vac to suck the water and junk up after you're done.
Should of pulled fan out to and cleaned the blades off to.. Also to check the bearings on fan.. Everyone needs to do this type of stuff once a year.. Save yourself money on doing things like this.. Change your filters every 30 to 50 days…
I watched an heat and air service person. He was enraged by DIY. He had made this point. He could make more money doing what he was trained to do, than he could save trying to figure out how to practice another profession.
It's actually recommended that I use that on my car whenever the cabin air filter is changed (Tesla Model 3, mine is the 2021 refresh though so it's more like the Model Y on the inside since it has the Octovalve). So in a year or two I'll get to have fun with a can of that. The blower didn't turn off cause you had the fan set to "auto". I have that same thermostat.
Nu Calgon 4168 Evap Coil Cleaner, better than that spray foam. Use the spray foam on the coils in the OUTDOOR unit. Buy 2 hand pump sprayers. Use HOT tap water in both. One sprayer has the coil cleaner mix, the other is plain water. Spray the cleaner on the A frame coils, let it work for some time, then rinse down with the plain water. Repeat until clean.
We never clean those in place, that dirt is so imbedded in there u just can't get them clean all you can do is get the surface stuff off. When we clean them we have to pump the refrigerant into the outdoor unit, disconnect the copper lines at the indoor coil, and pull the coil out of the air handler and take it outside to a hose. We use a foam cleaner, let it sit and then flush the entire coil. Then put everything back together. It's about a 3 hour job but it's really the only way to get them completely clean

Low pressure garden hose to rinse it.
Some brake clean would probably fix it, but could be the end of your coils lol
What??? Brakekleen wasn't available?

This is not the way to clean an evaporator coil. It needs to be removed for proper cleaning.
Nothing works like the real acid foam heating cleaners. I have a package unit and have to do it every year or so.
Years ago, at a factory I worked at we sprayed the coils and started the conditioner so the condensation rinsed it.
World's worst unboxing…
Ray, I hope you took that wet towel out before you sealed up the bottom so you don't get mold growing and blowing through your house.

would a pressurized herbiside sprayer would have worked !the ones you pump up,2 gallon size from home depot?
I used the spray cleaner and a garden hose spray noz and air hose worked tits.
Not saying your doing it wrong but there is a better way, get a chemical sprayer, clean it really good and fill it with water and voila….

Seems like most commenters below did not see the initial video!

Good job. A 2-1/2 gallon garden sprayer works well to spray the water over the coils, but whatever works. LOL
garden hose style

Time 4 a new filter? Maybe every 6 months when you change your trucks oil 😜
is it better than Brake Clean? 🙂
OE (operator error) blocked filter.
The moisture on the coils will help rinse it.
😂

Ray, you also, need to replace the filter, in the furnace door. That needs to be replaced, once a year, every year.

Give me your address I’ll send my 4 year old son around to show you how to spray with a can.
Not too bad of a job. Just 1 fyi.
A pump sprayer would have made life much easier.
Did it for over 20 years and I find it somewhat satisfying to watch someone else work on this stuff, lol.

I am curious how this stuff works. Does it insert itself in between the fins with force and then push the dirt and debris out as the foam expands?
get one of those 5 dollar pressure sprayers from Walmart's and fill it with water.
Use one of those pump bottle wand sprayers.
Try doing that in a 130°f attic

Hudson sprayer possibly?😊
Try to fit a wd40 nozzle with a bendable sprayhead on that foamcan(I think it's made out alu) it makes you're life so much easier
