Some of the incentives may be limited if you have too much income. I was able to get the latest Ecobee thermostat for $90 instead of the list price of $250. Fortunately or unfortunately, I started reading about how 3rd party thermostats can't talk to multi-stage furnaces or air handlers except in very blunt increments. Maybe as blunt as on or off. Each manufacturer has their own, undocumented protocol for doing fine adjustments. I tried running the fan all the time (now I do 10 minutes every hour) and it was quite expensive for that month. Anyway, I'm hesitating about putting in the nice Ecobee thermostat because it could conceivably cost quite a bit more in electricity.
