    Oh no, he is using fricking fuel-grade propane to fill his shitty AC with gas instead of R22. Now I am gonna go bankrupt

            Depends what you're asking. The compressor isn't breaking because it suddenly has the same refrigerant it's used to pumping, but with an odor that represents some level of non-condensable, but regardless, still not as offensive as not having it running; which is the literal problem in some of Appalachia right now.

              this is how people here break their cars AC,

              they turn it off to save fuel, then when they want to turn it on on really hot summer days its broken.
              just leave the cars AC on and on Automatic and adjust the temperature to your need.

        R152a is a fantastic r12 replacement. I've used it on multiple r12 cars with great results. R134a conversion usually requires a bigger condenser

    The UV dye is my preferred choice now. Saved hundreds on parts with it. Last one was a power steering leak and everybody wanted to replace the pump but it was a simple o-ring.

      I have a tractor that i need to put some dye in to find the leak... I have never messed with the dye before. Good to know you have good luck with it. I do have some dye, an injector, and a uv flashlight so i think i should be all set!

      Damn thing leaks down fairly quickly but i cannot find the leak with soapy water...

            Depends on the outside temperature, when it's +40C outside it takes up to 6 or 7 minutes maybe. When it's in the 30's it's pretty much instant.

    I have a 20 ish year old York home AC unit that has stopped working. I can hear everything running properly, but it doesn’t blow cold air inside or warm air outside.

    But....

    The compressor sounds different then my next door neighbour’s unit. It’s like a motor running under load versus a motor running under no load. Mine is sounding like it is running under no load.

    My compressor is broken inside? Or does this sound like the run capacitor is bad?

    • 2 years ago

      If capacitor was bad it wouldn't start, did capacitor was failing compressor would have a shorter life
      If fan blowing outside?
      If yes, hours probably low of refrigerant, don't want to breathe that stuff.
      Topping up will make it cold but probably cause cancer in 5 years
      You need to fix the leak, or switch to propane or duster which is a bit safer to breathe
      What's the sticker say your unit is charged with

      If your refrigerant is low in the cooling cycle, your indoor coil should be freezing up or the copper loops at the top of the evaporator coil (indoor unit coil) should be not sweating. By top I mean the ones higher up from the ground. If your compressor is bad you should see zero sweat on any of the evaporator coil copper loops, because the refrigerant is not moving. Consider it like a can of pop you just pulled out of the fridge and how it sweats or how you check how much propane is inside a tank, same concept This is considering that your outdoor unit is still running,

      If your refrigerant is low, first check your drain pan of the evaporator coil in the indoor unit, if it feels or looks like there's oil, it's the coil. Meaning if it's a small leak (shoot r22 dye in it through the common suction port with gauges), charge it. If it's not you're going to have to get an old coil and get it installed or a whole new system (I already know it's an R22 system).

      Here's how you check if the compressor is dead. Take a meter, clamp the ammeter on the wires coming off of the capacitor on the outdoor unit (don't touch the capacitor or the contactor and don't touch the red thermostat wire to the blue or black one). You should have your fan running, which would be lower than the FLA on the nameplate. The compressor amperage should be higher than the FLA but lower than the RLA. If you can't find that the compressor is kill or out on internal overload if it's hot to the touch.

        Oh yeah, almost forgot on the compressor bit, check to see if there are any burnt wires on the outdoor unit, either behind the service panel (5/16th nut driver) or check the ohms on the plug sticking out of compressor with the wires on it. Don't forget to pull the disconnect before you do. Alternatively you could need a hard start kit and I know this is DIY, but don't do that yourself. Also if you haven't worked on anything electrical before, disregard both my posts. I don't want you to have a nice day.
        Hopefully it's just a simple burnt wire or the compressor terminal plug needs changed. https://www.electricalonline4u.com/2016/11/test-check-compressor-windings.html

        Lastly, one more thing, check to see if your coil is dirty or the filter. If its the coil use a toilet brush to gently clean it of debree. Then buy a can of no rinse coil cleaner and soak it on the fins. I didn't consider that you could have a quieter outdoor unit and maybe it's just that you don't change filters often. If you can't afford filters, get something called hog hair.

          Fricking your "condenser cleaner" labeling bullshit. I'm spraying that shit on the evaporator and rinsing it well. And by rinsing, I mean running a hose literally from any the frick where, to coil.

            Rather than just use a couple hundred grams of propane in a vehicle that already can carry 100 kg of flammable (or inflammable) liquid, we are going to save the environment with toxic refrigerant technology.

        The joke is all these new hyper-formulated refrigerants that break down quickly so they have a low "GWP" are actually infinitely more toxic to health in a myriad of other ways. But it's okay as long as mother earth is safe.
