Dan was so pleasant and did a very nice job. Also offered a bit of a discount for having furnace cleaned as well. I requested he come back for the furnace and the repair to the fireplace, if the quote works out.

Performed first year furnace cleaning; inspected the exhaust and intake PVC ensuring all connections were secured, removed and cleaned the burners along with the flame sensor, cycled the system on and checked gas pressures and did make adjustments on both stages, as well as performed a combustion test verifying no CO in the airstream. This system is currently operating normal and heating at 43 degrees at this time. I did want to make note I found a large amount of dust on the blower wheel this could potentially cause a reduction of efficiency by 30% I would highly recommend upgrading your filter to an electronic air cleaner to bring theses levels down in the home.

Completed AC replacement. Recovered refrigerant and removed old condenser and coil. Installed new coil in the plenum above furnace and set condenser on a new pad outside. Flushed then reconnected the lineset. Pressurized the lineset with approximately 320 psi nitrogen to test for leaks. Left nitrogen in lines until spring when we come back to do the start up procedure. Thank you for choosing Black-Haak. Please take a moment to fill out our online survey. Thanks, Craig.
