We moved in last year. We have a Rheem 5-ton air conditioner, circa 1998. On my spring preventative maintenance service, the tech told me the system probably wouldn't last much longer. Offered to sell me whole new system of course, because it's an R-22 system that "can't be upgraded". He said the system was "acidic" and the compressor was pulling a lot of amps (24.5A). The contactor and dual run capacitor were still "good".
- Would a start capacitor/relay help the system last longer? (unfortunately I've been reading the internet about 5-2-1, supco, etc)
- Can I help by changing my thermostat settings (cycles per hour, e.g)?
- Are there other options besides buying a whole new system?
Also I have an Aprilaire electronic air purifier, plugged into a always-live outlet. Thus, my system is set up for the blower (Trane XV80 variable speed) to run continuously. The house is large with a finished basement and only one HVAC unit/zone. I was told running the blower also helps circulate the cool air from the basement throughout the house.
- Is it the circulation worth the ~1 amp to run the blower all the time?
- Should I have the purifier and blower re-configured to run less often?
Thanks!
