You’ll pay $400 to $1,600 for the parts alone. Labor runs $400 to $1,200 with most contractors billing $50 to $150 per hour. Warranties run anywhere from five to 12 years and usually only cover the price of parts after the first year or two.

A heat pump or AC compressor (they’re identical) does what it sounds like. It compresses the Freon in the line which forces it through the system so it can pick up and disperse heat in the evaporator and condenser coils.
