Which HVAC system would you choose?
Hello, which of these two systems would you choose? I have a 2100 sqft 2 floor house built in 1928 with attic and basement in Arlington MA. I plan to finish the basement (~900sqft) in the next year or two. Both options are very similar in price, so that's not really a factor.
System 1: AC + hydro air
2.5 ton Carrier FV4CNF002 fan coil with ECM motor AHRI #3657139 and hot water coil in basement
2 ton Carrier FV4CNF002 fan coil with ECM motor AHRI #3657138 and hot water coil in attic
Two condensing units installed outside on plastic pad, Carrier 24ACC630A and Carrier 24ACC624A
Buderus GB142-30 condensing gas boiler, 96% AFUE
reuse existing indirect water heater
save cast iron baseray baseboards currently on first floor for when basement eventually finished
System 2: AC + furnace
80,000 BTU Trane XV95 Variable speed Furnace, XB14 3 ton Trane condenser, Trane 3 ton coil
60,000 BTU Trane XV95 Variable Speed Furnace, XB14 2 ton Trane condenser, Trane 2 ton coil ( Furnace boxed in attic to keep insulated )
2410 April Air Filter
Model 400 April Air humidifier (basement only)
Furnace sized for future basement zone
new 50 gal gas hot water heater
