Got a quote for new a/c system. Contractor is suggesting replacing the copper pipe for 400 extra.Says its better to replace it for the new refrigerant as the old piping contains deposits from the old refrigerant that will degrade the new type. I don‘t know, but this smells like he may be trying to make easy money. So, the question is. is this usual and customary and normal? Thanks in advance for you answer. And, please don‘t reply unless you have experience in hvac.
