I recently purchased a vacation home that has two thermostats for a forced hot air gas furnace and a separate A/C unit that shares ductwork. The A/C also cools better when both the A/C and furnace fan are running.
I’d like to consolidate thermostats but don’t want the A/C fan running when the heat is on.
I was thinking about wiring the A/C fan connection to the compressor connection on the thermostat. That way the fan and compressor would run along with the furnace fan when the A/C is on but when the heat is on, only the furnace fan would run.
Does anyone see any issues with wiring it this way?
