Question DetailsAsked on 4/24/2015

Air Conditioner Refrigerant (R-22) - is it reusable?

Older Lennox system would't start this year. Tech found "bad TXV valve at condenser." They had to order the part and just called to tell me that it would cost $825 to replace the refrigerant (AHS will pay for 5 lbs, the additional 15 lbs at $55 per lb. is my expense!) They have to drain the refrigerant to replace the valve. When I asked if they could reuse my refrigerant, they said "NO" - that it would be contaminated. Is this true? I've read that R22 is being reclaimed from the order units, and, I assume, resused?

Federall law requires all R22 to be "recovered" by the contractor. If contaminated it should not be reused, it should be sent to a company that can "redistill , remanufacterer" it , thus making it reuseable.

That said a TXV failure should not contaminant the R22 in a system.A burnt out comporessor would be. 20 lbs,is a lot, what size AC system, in tons do you have?

What I've read on AC Contractor Forums is, home warranty companies do not pay contractors enough to make a normal profit, so if a contractor works for them, they need to find things that are not covered by the warranty and charge as much as possible to the homowner. Not saying that is the case here, but it could be.
