How do you flush an air conditioner condenser?
Disconnect the low-side and high-side refrigerant hose from the condenser using an adjustable wrench. Pour the flush solvent into the high-side inlet of the condenser. Apply compressed air into the high-side inlet of the condenser. Catch flush solvent with a dense rag as it comes out of the outlet hole in the condenser.
How does AC high side and low side work?
AC works by compressing refrigerant in the compressor (the beginning of the ‘high side’), cooling in the condensor it, and then expanding it to absorb heat (where it enters the low side). Then the low-side piping takes is back to the compressor, where the cycle starts over.
Do you have to flush the AC system before replacing the compressor?
