We need to replace our AC. I have 2 quotes so far. One is for a 14SEER 3-1/2 ton Rheem, RAPC042JAZ, with an evap coil 24x21 Aspin 4 ton. This uses R22.
The other is for a 3-1/2 ton Lennox 14SEER XC15-042 with Evap. CH23-51, which uses the new stuff. The Lennox is significantly higher in price.
I'm hearing conflicting stories on the refrigerants. One says it is better to stay with the R22 because it is not a blend and that they had tried using a blend once before and it wasn't successful. Can anyone give me some insight into all of this. I'd like to make the right decision and get the best unit for the price. Thanks!
