Completed replacement of gas furnace and installation of Aprilaire #600 humidifier. Disconnected and removed old furnace and set new one on blocks in its place. Reconnected the electric, gas, pvc vent piping and ductwork. Ran a new condensate drain hose for the furnace, new AC coil and humidifier drains. Installed a new T6 WiFi thermostat and connected it to the furnace. Installed the new Aprilaire #600 humidifier on the return duct and ran the bypass to the supply plenum. Installed humidistat on return also and ran all control wiring into the furnace. Run tested the furnace and humidifier but will still need a technician start up on the furnace. Installed the AC coil but will return in spring to complete AC work. Thank you for choosing Black-Haak Heating. Please take a moment to fill out our online survey.
