Completed gas furnace and AC replacement. Disconnected and removed old furnace and recovered old refrigerant and removed old AC. Set new furnace on blocks and reconnected the gas, electric, pvc piping and ductwork. Reconnected the existing Aprilaire. Installed a new Comfortnet thermostat and connected it to the furnace. Set new AC on a new pad outside and flushed then reconnected the refrigerant lineset. Installed a TXV at the coil inside the furnace plenum and connected lineset there also. Pressurized the lineset with approximately 325psi nitrogen to test for leaks but will need to return to do the start up in spring when weather is warmer. Run tested the furnace but will still need a technician start up. Thank you for choosing Black-Haak. Please take a moment to fill out our online survey.

Performed level 2 furnace and fireplace cleanings. Furnace: Burners and flame sensor are clean. Heat exchanger looks good. Gas and exhaust levels are normal. No CO detected in the air. Drain is clear. Heat rise was 54 degrees. Fireplace: Glass is clean. Pilot assembly is a little worn, but I was able to clean it out. I wiped and vacuumed away any dust there was and replaced the embers. Fan motor wasn’t kicking in prior to my arrival. I tried to get at the motor with no success. Due to the fireplaces system, I recommended customer to Darboy Stone and Brick. We will return to install a 413 filter upgrade pack and for an AC cleaning. Thank you for choosing Black-Hawk!

Was here for a furnace no heat. Customer said that the furnace would shut off and not run. He would reset the furnace, the furnace would start and heat for a while and then shut off. Found that the furnace wasn’t draining properly and was backing up into the furnace. Shortened up the drain hose to allow for more pitch. The furnace is running normally at this time. Told customer to call us if there are any more issues with the furnace. There is no charge since we just installed the furnace.

No heat for the living room. All the other radiators were hot though. Found the boiler had no pressure. The fill valve has failed. I filled the boiler with a hose to 20 psi. Bled air from the living room radiator. The system is heating now. We will need to replace the fill valve and the expansion tank. In order to do the repair we will need to drain the system and refill it. Jamie will quote the repair.
