    I’ve been in the cleaning industry 32 years and you need to add some soap. The difference is night and day. You could just use a little dawn in a spray bottle and mist it. Let it sit for a minute then rinse. It will be way cleaner. I do clean frequently because my AC is right next to my dryer vent. Good job builder.

    Good tip video. I used to have quite a few cottonwood trees around me and the coils would have a layer on them much like your lint trap. The coils would have to be cleaned twice per season. Over the years with the removal of the trees, a huge decrease in debris from the trees with cleaning once and sometimes so clean not even needing it.

I'm a Mechanical Engineer with 42 years of experience and am wary about using those foam products. I have a Miitsubishi Mr. Slim Minisplit and a Comfortmaker for the other side of my house. Both units were installed in 1999 and run like new. I keep them clean and maintain them well. I had a couple of indoor unit control boards blow over the years and couldn't find replacements. I found a repair source in Australia and sent them the boards from the US. When I got them back I installed them and success! I like your channel and keep up the good work!

This year I tried some cleaner with a foam cannon and also removed the top to get the front and back of the coils.

      This guy is a amateur at best doing a huge disservice with his "advice". He says they rarely get blockage in between. That simply isn't true and I find them like that all the time. In which case you have to run the unit while quickly and carefully whisking over with a propane torch to suck in the flame and set the cottonwood on fire. You do this very carefully and with a hose turned on and right next to you in case it gets out of hand. Don't stay in any one spot for more than a fraction of a second or you will damage the aluminum coil. After it's all burnt and the smoke was expelled through the top via the fan running you turn off the disconnect switch and go about it as normal. All the ash and residue washes right out.

      Really appreciate you sharing your excellent knowledge about HVAC systems. I have question about compressor freeze up. If on a 90+ degree days and we set the thermostat temperature to 60 degree, will it cause the system to freeze up? Been getting conflicting answers, some tech said yes and some said no. What's the correct answer? Thanks in advance!

      It depends on your specific setup and condition of your system. If you have a "dumb" system and your airflow is limited (such as from a dirty filter or undersized ductwork) it will probably freeze up. If your system has great airflow and is properly charged it will probably be fine. Usually it's recommended not to cool below 68F or so just to be safe. If you want it colder you can get an inexpensive freeze protection control installed which monitors the operating temperature and shuts off the compressor if it gets close to freezing. If you have a modern inverter-based system like a mini-split it probably has this protection built-in.

      Nope....air conditioners are only rated to cool 20 degrees colder than outside. You might get a bit more but no way you could ever pull down to 60 on a 90 degree day outside. That unit will freeze up. And yes, I am a licensed professional!

      @JohnDoeEagle1 I just looked at some datasheets and the equipment is totally rated to cool into the sixties when it's 115 outside. Obviously the actual temperature performance depends on the unit size and thermal load. If you're in a cooler climate a sensible installer might size the equipment only to cool 20 degrees below outdoor temperature but the same building in a hot climate will get a larger capacity unit.

      Not true....if the equipment is big enough to go below that it's a "chiller" not a a/c. They use different Freon, different compressors, different pressures etc etc.
      There's no R-22 or R-410A unit capable of such a thing.
      R-23....aka "Agent Orange"....likely so.

      one particularly warm year when my condenser was running a lot, it got a thick "sweater" of Cottonwood seeds caked on it in a matter of weeks. HVAC companies in this area must really make a killing with all the "cottonwood killed" A/C condensers. Cottonwood seeds don't wash off like dirt and dust, so you have to shoot water from the inside out to remove them. Those who don't live in an area with light, fluffy Cottonwoods just don't know.

    No issues with your feelings towards cleaning product, they could corrode. If a customer pays they are getting a tare down and full cleaning and proper reassembly with new ties for wire retention.
    But if they need a simple hose down i encourage them to save money and do a little bit on their own. You might be surprised at how many people do not want to do simple things to save money or keep a warranty.

      Really appreciate you sharing your excellent knowledge about HVAC systems. I have question about compressor freeze up. If on a 90+ degree days and we set the thermostat temperature to 60 degree, will it cause the system to freeze up? Been getting conflicting answers, some tech said yes and some said no. What's the correct answer? Thanks in advance!

      It depends on your specific setup and condition of your system. If you have a "dumb" system and your airflow is limited (such as from a dirty filter or undersized ductwork) it will probably freeze up. If your system has great airflow and is properly charged it will probably be fine. Usually it's recommended not to cool below 68F or so just to be safe. If you want it colder you can get an inexpensive freeze protection control installed which monitors the operating temperature and shuts off the compressor if it gets close to freezing. If you have a modern inverter-based system like a mini-split it probably has this protection built-in.

      This guy is a amateur at best doing a huge disservice with his "advice". He says they rarely get blockage in between. That simply isn't true and I find them like that all the time. In which case you have to run the unit while quickly and carefully whisking over with a propane torch to suck in the flame and set the cottonwood on fire. You do this very carefully and with a hose turned on and right next to you in case it gets out of hand. Don't stay in any one spot for more than a fraction of a second or you will damage the aluminum coil. After it's all burnt and the smoke was expelled through the top via the fan running you turn off the disconnect switch and go about it as normal. All the ash and residue washes right out.

    Great video. I think your myths make more sense in areas where there are no trees and little pollen. Here in North Carolina, leaves, maple tree pods, etc. add to the heavy pine pollen to really create a mess on the inside of the unit. So I do unscrew the top, vacuum out all that debris and apply cleaner and water from the inside out. I get much better access to the fins this way as the outside cover is not in the way. But I can see how my method may not be necessary in other areas of the country. Thanks for doing a great job on these videos. 👏👏👏

      I'm just a middle aged idiot dad with no mechanical or relevant background, but we installed a 3 unit Mr cool mini split about a year and a half ago and have loved it.
      We live in a double wide with one towards either end of the house (master bedroom and living room) and one in the middle (dining room), all on the same long side.
      It was very easy to install* and once we figured out that you can't use the mobile app and the remote controls at the same time, have had it running flawlessly the whole time.
      *The hardest part of installing it was running power from the breaker to the other side of the house, but we found a video that walked us through every step (gotta love TH-cam), and changing out the power lines for each indoor unit.
      They are a specific length and since we were running them further, we needed to swap them.
      It was difficult because the wire goes into a tight area and is thicker than the hole it goes into which was frustrating, but once done, it was pretty easy the rest of the way.

Also do it for your A coil, the evaporating, or cooling coils. No need to hose down as the condensate will rinse it away.

    I just pull the couple screws off the top, lift out the fan assembly, spray it all down with simple green -best cleaner hands down except purple power (purple power is lightly corrosive on aluminum and will etch the surface shiny clean) and hose it from the inside out/top down. It legitimately gets alot more crap out. Rather than pushing it IN like just spraying from the outside does. The airflow is drawing crap into the fins from the outside toward the inside. You cant really push it all the way through clean.. youll compact it in partially. Same as cleaning a car radiator or intercooler. Wash opposite of airflow. Youll double the amount of crud you clear out

    Great videos man. Ppl must be hating on you for doing these. But good for you because in a time like this where everyone is going broke they need to learn this stuff so they don’t sit without A/C. I know a ton of ppl that do and i don’t have enough time to help them all for free. It’s not my field but i know the basics of most issues. I will watch your video on changing a unit-i basically know how and have helped a few times back when it was switching from Freon to 410A. I own gauges and use to top of ppls units that were dying while they saved money to upgrade to 410A. I might have to pay you to hop on video at somepoint when i change a unit i have to for my mother in law who’s broke. Pretty sure i can do the handler no problem run the lines from co denser and install that -it’s just the leak test stuff and I’d have to buy that and that little compressor you use.
    To the ppl watching this …most everything that commonly breaks on your A/C unit or makes it stop working is really an easy fix-this next video for the capacitor is very common and super easy to do if you don’t overthink it-it’s a giant fuse but basically is comparable to changing out something like a 9 volt battery in a smoke detector. Just like cleaning these coils are like cleaning out your window screens or a 10 foot gutter and changing a fan on the outside unit is easier than changing a ceiling fan and the last thing is the drain line and just sucking that out with a shop vac. You can save yourself from no a/c or not affording to get it fixed-all these parts are pretty cheap compared to hiring someone. He’s definitely pissing off A/C companies by really showing you how easy most of the common problems are and not exaggerating on skill level or price of these things to do yourself. You can pretty much start an A/C emergency fix it company out of your car with universal Capacitors, universal fans, a shop vac, coil cleaner and foil tape & tiny tool box. You’ll be able to get 90% of people’s broken A/Cs running.

      I'll add that everyone should have a capacitor on hand. They're inexpensive and probably the number 1 failure reason for AC's. Note though that the replacement is quite easy with only 3 wire terminals to unplug and then replug to your new capacitor. BUT, realize capacitors store an extreme amount of electricity that MUST be discharged before doing the replacement. Those with no basic skills around electricity should not perform this function.
