Replace A/C compressor/coil only or gas furnace too
Both of my A/C units are low on R-22. Service tech recommended replacing (units were orig. to home built in 1998).
I live in Northern VA (outside DC). 2 story colonial (approx 3000 sq ft + finished basement).
System #1 (1st floor & basement)
Bryant A/C 561CJX036-D
Bryant Gas Furnace 383KAV036070
System #2 (2nd floor - unit in attic)
Bryant A/C 561CJO018-C
Bryant Gas Furnace 376CAV024050
My question is: should I replace the furnace(s) as well as the compressor(s) & coil(s). The furnaces work fine right now.
I am just getting started w/finding a contractor.
Any recommendations for installers would be greatly appreciated - particularily any who perform load calculations.
