    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 .

    Low pressure garden hose to rinse it.

  3. Avataaar/Circle Created with python_avatars Arnold M says:

    Some brake clean would probably fix it, but could be the end of your coils lol

  4. Avataaar/Circle Created with python_avatars Stan S says:

    What??? Brakekleen wasn't available?

  5. Avataaar/Circle Created with python_avatars Patriot70 says:

    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.

  6. Avataaar/Circle Created with python_avatars Mike Rigatuso says:

    This is not the way to clean an evaporator coil. It needs to be removed for proper cleaning.

  7. Avataaar/Circle Created with python_avatars Big Jeezie says:

    Nothing works like the real acid foam heating cleaners. I have a package unit and have to do it every year or so.

  8. Avataaar/Circle Created with python_avatars Alan Engels says:

    Years ago, at a factory I worked at we sprayed the coils and started the conditioner so the condensation rinsed it.

  9. Avataaar/Circle Created with python_avatars Chris Jarrett says:

    World's worst unboxing…

  10. Avataaar/Circle Created with python_avatars Paul Bernauer says:

    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.

  11. Avataaar/Circle Created with python_avatars Chris Muro says:

    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

  12. Avataaar/Circle Created with python_avatars fred a says:

    would a pressurized herbiside sprayer would have worked !the ones you pump up,2 gallon size from home depot?

  13. Avataaar/Circle Created with python_avatars Don Gillespie says:

    I used the spray cleaner and a garden hose spray noz and air hose worked tits.

  14. Avataaar/Circle Created with python_avatars Bobby Hicks says:

    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….

  15. Avataaar/Circle Created with python_avatars robert boyd says:

    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.

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

  17. Avataaar/Circle Created with python_avatars Hector Estarellas says:

    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

  18. Avataaar/Circle Created with python_avatars Kent Owens says:

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

  19. Avataaar/Circle Created with python_avatars Linux Jedi aka Big Evil says:

    garden hose style

  20. Avataaar/Circle Created with python_avatars keep thinking says:

    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

  21. Avataaar/Circle Created with python_avatars Thomas M Leahy says:

    Pressure washer style

  22. Avataaar/Circle Created with python_avatars Scotty Bear says:

    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

  23. Avataaar/Circle Created with python_avatars Melanie Branton D.V.M. says:

    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.

  24. Avataaar/Circle Created with python_avatars Emerald Penguin says:

    Time 4 a new filter? Maybe every 6 months when you change your trucks oil 😜

  25. Avataaar/Circle Created with python_avatars ji Leb says:

    is it better than Brake Clean? 🙂

  26. Avataaar/Circle Created with python_avatars Michael Lonsdale says:

    OE (operator error) blocked filter.

  27. Avataaar/Circle Created with python_avatars Poppi Arlin says:

    The moisture on the coils will help rinse it.

  28. Avataaar/Circle Created with python_avatars Poppi Arlin says:

    😂

  29. Avataaar/Circle Created with python_avatars Henry Bucki says:

    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

  30. Avataaar/Circle Created with python_avatars Billy Smith says:

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

  31. Avataaar/Circle Created with python_avatars Tim Davis says:

    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.

  32. Avataaar/Circle Created with python_avatars Allen Westland says:

    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…

  33. Avataaar/Circle Created with python_avatars jake legg says:

    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.

  34. Avataaar/Circle Created with python_avatars cype man says:

    Give me your address I’ll send my 4 year old son around to show you how to spray with a can.

  35. Avataaar/Circle Created with python_avatars Crash4taz Gaming says:

    Not too bad of a job. Just 1 fyi.
    A pump sprayer would have made life much easier.

  36. Avataaar/Circle Created with python_avatars Christopher Belton says:

    Did it for over 20 years and I find it somewhat satisfying to watch someone else work on this stuff, lol.

  37. Avataaar/Circle Created with python_avatars Stormspark says:

    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.

  39. Avataaar/Circle Created with python_avatars Josh Nabours says:

    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?

  40. Avataaar/Circle Created with python_avatars The Grumpy Old Man says:

    get one of those 5 dollar pressure sprayers from Walmart's and fill it with water.

  41. Avataaar/Circle Created with python_avatars Rick Blanchette says:

    Use one of those pump bottle wand sprayers.

  42. Avataaar/Circle Created with python_avatars Jacob Simerman says:

    Try doing that in a 130°f attic

  43. Avataaar/Circle Created with python_avatars Thomas Szilagyi says:

    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.
