I am looking at replacing a horizontally mounted 3-ton system for the upstairs of our 2-story 3500 sqft Atlanta GA house. We hate "dry heat" and have lots of allergies. I am considering Carrier and Trane.
I am thinking about this system:
Carrier Infinity 3 ton 2 stage Puron up to 17 SEER A/C (model # 24ANA736A003)
Matching high efficiency horizontal tin plated cooling coil (model # CNPHP3617ATA)
Carrier Infinity 80% efficient variable speed 2 stage gas furnace (model # 58CVA090-1-16)
Carrier Infinity air cleaner with a matching 16 x 25 return air drop box with sealed fittings to control air infiltration.
Carrier Infinity controller relocated to the master bedroom with dehumidification enhancement, humidification enhancement, temperature and indoor air quality monitoring.
For the humidity, a new Honeywell 12-gallon steam humidifier with a new Vision Pro thermostat and new water shut off valves for the existing main floor system and an additional return upstairs to balance out the air flow.
Can you pros comment on this system and advise?
Also, and very important, should I do the above A/C or the heat pump option, especially for Atlanta's climate:
Carrier Infinity up to 16 seer 2 stage heat pump in lieu of the above air conditioner??
Thanks for you guys' advice!!!
