They did a fantastic job cleaning out our furnace and HEPA filters. Very friendly and when we set the appointment the office personnel were nice and professional on the phone. I highly recommend Black-Haak for any heating or air conditioning needs.

Performed the level 2 furnace cleaning. Burners and flame sensor are very worn and rusted. Heat exchanger was also rusted and I had backdraft from the powder test. Venter and blower motor bearings are starting to go. Both motors are loud upon starting. Average life of system is 12-14 years. Unit is currently 22 years old. Due to age, condition, and cost of future repairs, second opinion is recommended. Unit is currently safe to operate but we cannot conclude for how long.

No heat. Upon inspection the furnace was flashing a code of open pressure switch. Inspected pressure tubing and drain. All were clear. Inspected ventor motor and found it seized. Removed old ventor motor and replaced with new ventor motor. Ran and tested unit. All systems operating properly at this time.

Came out to investigate a no heat. The home was sitting at 59 degrees and the stat was calling for heat. I found the furnace didn’t have a fault code or a call for heat. I jumped R and W on the board and the furnace fired up. I checked the zone board and had 24v from R to W on zone one, but not zone two. Th zone board is faulty and needs to be replaced. We will quote a price Monday. The furnace is currently jumped to be operated from the downstairs thermostat.

Completed gas furnace replacement and Aprilaire 600 humidifier. Disconnected and removed old furnace and set new furnace on blocks in its place. Reconnected the electric, gas, pvc venting and ductwork. Installed the new Aprilaire humidifier on the ductwork and wired it to the furnace. Ran new drain hose for the furnace, AC and humidifier to the floor drain. Installed a new T6 WiFi thermostat and connected it to the furnace. Run tested the furnace and humidifier but will still need a technician start up. Thank you for choosing Black-Haak Heating. Please take a moment to fill out our online survey.

Performed furnace clean and tune; 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, as well as performed a combustion test verifying no CO in the airstream, and lastly connected 2 lyric water leak detectors one by the furnace and one for the sump pump. This system is currently operating normal and heating at 54 degrees at this time. Job complete

Performed furnace start up; inspected the exhaust and intake PVC ensuring all connections were secured, sniffed the gas line for possible leaks, 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. I did a refrigerant leak search on the systems evaporator coil and found an indication of a leak. I highly recommend having the AC cleaned this spring to ensure operations and to prevent any issues with the new furnace. Humidifier was unplugged because it leaks during operation I am including a quote for a replacement humidifier. Everything is operating normal at this time. Job complete second opinion scheduled with Dan F Monday 03/25/19 at noon

Fireplace inspection. Cycled fireplace. System lit immediately. Flame is correct height and color. Adjustment for gas pressure and flame intensity is operational. No CO from door seal. Fireplace has aftermarket fan that was installed due to this model was not manufactured with fan in place. Fan has a magnet mount thermistor that uses heat to indicate when the fan should engage. This causes the fan to have a longer time before fan start up. Fan did engage after several mins with no issue. Fan is operating normal at this time and is quieter than most factory installed fan motors. Customer will clean glass. System operating normal at this time. Job complete.

Furnace clean and tune. Cycled system, checked heat exchanger, found some rust and damage. Checked and cleaned burners and flame sensor, burners were extremely worn and rusted. Flame sensor was also very worn. Cleaned both as best as I could. Burners still very rusted. Checked gas pressures and adjusted to maximize efficiency. Checked levels of CO and XS air in exhaust. Normal levels found. No CO found in airstream. Found evidence of water leak from ac coil in blower compartment. Office to call in spring for possible ac clean. If cleaning is done and conditions require replacement, all fees that were charged for the ac work will be refunded if replacement is made. System is howling signs of heavy wearing. Average life of this unit is 14 years. Job complete.

The furnace was giving a burning smell and was really hot. I cycled the furnace and found the blower motor wasn’t getting up to speed. I tested the capacitor for the blower motor, it was good. I tested the blower motor windings. The windings are failing. The blower motor needs to be replaced. The office will call with a price for the blower motor, I recommend having a clean and tune done on the furnace. Office will call to set up furnace clean and tune and blower motor replacement. Dan will pay when job is done.
