My R-22 central air unit compressor needs to be replaced because it must be locked up and blows the circuit breaker. I have an estimate to replace the unit with the upgraded Freon, but since I'm just looking to sell the house ? Was wondering if any HVAC repair guys had a cheaper option,like replace this compressor with another, just so it passes inspection, and work of course. I live in the Salisbury area and any help would be greatly appreciated. Call me at 704-433-9586 or respond here.
