Replacing condenser unit
After considering a whole system replacement for my 3-ton 1977 vintage Payne system, I'm looking at just doing the condenser and keeping the existing coil and lines. The contractor can give me a Thermal Zone R22 unit installed for $1800. I can't find much on the brand beyond it being a Rheem brand. I'm told if needed in the future, I'll be able to match a coil to that unit. I would appreciate any feedback on Thermal Zone and my plan. Finances prevent whole system replacement at this time. Thanks!
