I'm extremely new here so please let me know if I'm posting things at the wrong place. I recently (3 months ago) installed a new Trane 2 stage ECM furnace and along with it an Aprilaire 600 whole house Humidifier. It's upstate New York here, I've been setting the the thermostat to 73 degree, so furnace officially started working since late September.
