Is it important to check York aircon compressor sump oil level when re-gas the A/C? 200 1979

Every four years I need re-gas my replacement York compressor to maintain adequate cooling. Both gas and oil have slowly leaked out (underneath compressor wet with oil) but I am concerned that eventually the sump oil level will get too low and the compressor seize. At my last re-gas up I asked the aircon guy to unscrew the sump oil fill plug in the side of the compressor and use a flexible wire dipstick to check oil level before regassing. He just said he didn't want to do that, but then said he will put one once of oil in the system via the suction line, but this does not fill the sump. Also he put the new drier in back-to-front which does not give me confidence. My York compressor is 8 years old and gives ice cold air when its regassed, and then good cooling for 4 years. Its time to regas next week.

If aircon guys wont do this job, I am prepared to let the remaining gas out, pull the fill plug, check oil level or suck it all out to check volume, and fill with oil (if someone can tell me the amount - onces, or cc (cubic centimeters), or oil level depth (1 inch??), then get an aircon guy to just regas.

    I don't believe it was part of the routine, when topping off. You're closer to the place where the hole in the ozone increased UV, too.

    But, Michael, that receiver being reversed seems counterproductive, given the dip tube in it, I think, is there to be sure your liquid line is liquid.

    Mighty envious here, of whatever temperature you are trying to lower.

      How to get ice cold air at no extra cost and not with R134 200 1979

      Thanks Art for your info. I was concerned since supply & fit & gas York compressor cost A$821 plus a seized compressor can contaminate the entire system with fine metal particles. All the seized compressors on BrickBoard must have leaked oil to seize so its a real problem. Dont want that compressor to run dry but hard to assess the extent of the oil leak without checking the sump oil level.

      Nearly all aircon shops in Australia (and I guess America) want to convert Volvo old R12 aircon to R134 aircon by doing most of the mods listed on Brickboard (pusher fan, Tx valve, maybe new condenser, etc) and charging about A$1300 to A$1500. (Only a licensed aircon tech can get refrigerants in Oz - no WalMart here). Ouch!

      So I just had the remaining R12 removed and had the system refilled with HR12 and replaced aged drier for A$160. Thats all! Its just a hydrocarbon refrigerant which is being used legally around the world - dont know if available in USA. Yes its flammable, but there have been no reports of cabin fires due to crashes. Its more efficient and cheaper than R134. The curious can check it out at www.hychill.com.au

      I'm putting it to the test today with temperature in Adelaide at 44C (111F)

        Hey Michael, I figured you wanted the Volvo position on checking the oil level. Knowing you have HC replacement makes it much easier to check the level, given the expense and upper level ozone are removed from the picture.

        Here we can buy HFC134a at Walmart.

        There have been a couple lengthy threads on turbobricks on HC replacements; propane in particular. I understand the US ban on it; it is permitted in some experimental stationary commercial applications, but the industry has to show the components are designed for flammable refrigerants before it will be accepted. And it will be. Some say it has to show DuPont a profit before it will be accepted, but I think Honeywell has the latest corner on automotive refrigerants.

        It is odd to me most people think of cabin fires as the danger. I think of the reason we want to use it in the first place: our cars are leaky. HC is cheap. Then we park them in a closed, attached garage. Well, there's really very little refrigerant in a car; not like your BBQ. Legally around the world? That's news to me; I've heard GB was testing it, but that was a year ago.

        If you lend someone $20 and never see that person again, it was probably worth it.
