Replacing Heat Pump advise
I am in the market for a new Heat Pump to replace my 13yr old 3.5 ton bryant with 15kw heat strip and zone kit (not replacing the zone kit) for the third floor. This unit will heat and cool my 2nd and third floors 2039 total sq ft. The current unit has cooled and heated nicely over the years. I was told to stay with a Trane unit but was also told they don't make a 3.5 ton. I live in NC and the summer is hot and humid. In doing some research I heard about SEER,2 stage compressors, variable speed air handlers, IAQ thermostats etc. What model # Heat pump& size, air handler, stages (because of heat and humidity) thermostat etc should I go with. Any advise would help and be appreciated. Thanks!
