Thermostat Options
When replacing your thermostat, there are 2 choices: a “Heat Only” thermostat and a “Dual Function” thermostat that operates your furnace AND air conditioner. When replacing the thermostat in a “Dual Function” setup, we’ll need the model numbers of your current furnace and current air conditioner in order to source a replacement.
How to find your air conditioner’s model number?
Thermostats are model specific; if you are unsure of your air conditioners model number, remove the shroud cover on the unit, there is a label affixed to the unit itself that will have the model number on it.
