My residential R-22 heat pump is being replaced this week with heavy involvement of this author. The old 2 ton system experienced compressor burn-out and loss of all R-22. When we severed the copper lines the stench of burned compressor oil permeated the house.
I'm replacing the entire A/C system (new A-coil and condensing unit) but not the copper lines. Replacing these lines would require re-drywalling the living room ceiling and a petition to the architectural committee of the condo association.
I intend to blow out the copper lines with an air compressor and tank and thereafter evacuate these lines with a pump. A new filter dryer on the new system is assumed.
Would back-flushing the copper lines with a gallon of new, clean, R22-compatible refrigerant oil be helpful and contribute to longer life of the new system?
Given that I am putting a new condensing unit and A-coil, is flushing of the existing copper lines even necessary? Could be that I'm being too anal about this.
