Completed gas furnace replacement. Disconnected and removed the old furnace and set new furnace on blocks. Reconnected the gas, electric, pvc venting and ductwork. Installed a new T4 thermostat and connected it to the furnace. The installation is complete but the office will contact you to schedule a time to have one of our service techs come do a complete start up procedure. Thank you for choosing Black-Haak Heating and Electrical. Please take a moment to fill out our online survey.
