I'm looking to upgrade my builder grade Goodman system to a GME95 furnace with SSX14 AC Compressor. Its a two zone house, so I'm getting 2 of each.
My question is w/ regards to two stage heating. I had inquired if the upgrade price included 2 stage thermostats. The builders sub responded that you only need a 2 stage thermostat when you have 2 stage A/C - the 2 stage heat is done internally at the furnace so there is no need for the 2 stage thermostat.
Does that sound right?
Thanks in advance.
