My present 14 year old system ,RUUD 3 TON (SPLIT) ,just conked out. I have received estimates from two very reliable contractors.
One suggested a Rheem 14 seer RPPB SERIES(SPLIT SYSTEM) ,uses R22 freon. The other suggested an Amana Tempassure 14 seer RHF 36c2c (split system) using the newer R410A FREON .

I am concerned with the availability and costof R22 in the future along with reliability, efficiency, and quality.

Any recommendations or suggestions?

I didn't mention the cost , but one system is about $700 less than the other.
