  • Is R32 really this hard to come by? : r hvacadvice - Reddit
    How many professional opinions of "this unit isn't dead because of being low an insignificant amount of refrigerant and is instead dead because it either all leaked out due to an unprofessional installation or that it's a garbage china diy unit" is this dude going to ignore lol
  • R410A to R32, why not go back to lower pressure like R422B or . . . - Reddit
    R410A to R32, why not go back to lower pressure like R422B or 407C? I'm convinced that we're having so many problems with newer units partly because of the much higher pressures of 410A And they replaced 410A with R32, which operate at the similar pressures Why not move from 410A to 422B or 407C?
  • Two more sets of gauges for the new refrigerants? : r HVAC - Reddit
    Propane isn’t an A2L, it’s an A3 R32 is already half of what’s in R410A and R454B is almost 70% R32 R32 isn’t a hydrocarbon refrigerant
  • This guy is crazy, right? I cant just put r410a in a r32 . . . - Reddit
    He’s actually completely right You can drop r410a into a r32 system without much issue The only problem you might run into is a R32 compressor has less displacement than 410a so you would be down capacity With all that said though, there is a reason units are specified with a particular refrigerant I would not recommend doing this unless you really know what you are doing or if it’s in
  • To flush or not to flush, that is the question : r hvacadvice - Reddit
    Simply put, if it’s a burnout then you need to flush because of possible contaminants in the line set or if it’s because the old system has been leaking you need to flush again because of possible contaminants or if your replacing one perfectly good system for a new one that is a different type of refrigerant you need to flush because of
  • AC installers topped up R410A unit with R32 : r hvacadvice - Reddit
    When they began filling this older unit with the same R32 refrigerant they used for the newer units I've obviously asked if it's compatible and they said yes, that in layman's terms R410A is a diluted version of R32 and it's fine
  • Can R32 gas in my home catch fire or explode if it leaks from . . . - Reddit
    Can R32 gas in my home catch fire or explode if it leaks from my split AC I am worried My split AC has gas leakages once in few months I recently got to know r32 is flammable compared to r410a Should I change my whole system to R410a? what if theres a gas leakage and i dont know about it and i smoke a cigarette and use my lighter?
  • what can i use as a drop in replacement for r32 refrigerant if . . . - Reddit
    If you don’t know what subcooling or superheat are and how they correlate to the amount of refrigerant in the system then you couldn’t get a proper charge even if you had a replacement Mixing refrigerants is unwise as it can damage your equipment, pressures are different for each and every refrigerant
  • How to dispose of AC units? (Non-CFC) : r AskNYC - Reddit
    The department of sanitation arranges for refrigerant removal and pickup for AC units that contain CFC’s (like Freon) The two units I have don’t contain a CFC refrigerant, they have an HFC refrigerant, r410a
  • Question about vacuum pump (R32) : r hvacadvice - Reddit
    It's using R32 refrigerant Also, on the exterior unit, there is only one of the two valves to be vacuumed, with a small nipple inside that I guess will close the valve once I'll disconnect the vacuum pump
