Wonderful person, Little experience




Julian was very friendly & personable. He even drove back to the shop to pick up forgotten equipment. Appeared to be pretty rough/hard on internal components of furnace. Seemed to forget some connections/tools frequently. Made me a little nervous.

Good job!




Black-Haak has a good good employee group, across the board. Technically they're good but also considerate and social. As a former business owner I recognize that trait and appreciate it. I believe that to be especially important when working in homes.

Performed first year furnace cleaning; inspected the exhaust and intake PVC ensuring all connections were secured, I then removed and cleaned the burners along with the flame sensor, Next I cycled the system on and checked gas pressures and did make an adjustment on low stage, next i performed a combustion test verifying no CO in the airstream, lastly took a delta T and got 36 degrees made an adjustment to the fan speed and got a new temp rise of . Did want to make note we do have high levels of carbon dioxide, chemicals, and particles in the air I am including an estimate with an electronic air cleaner and UV light to help bring these levels down. This system is currently operating normal at this time. Job complete

Performed furnace clean and tune; cycled system on and found the Tstat set point was at 65 and the inside temp was 62 the system was not running, I then cycled power to the system and did get ignition, Next I removed and cleaned the burners along with the flame sensor, performed a heat exchanger powder test and did get blowback from both cells, tested out the igniter and that tested weak, next I performed a combustion test verifying no CO in the airstream. This system is currently operating but future failure is expected with the amount of bearing wear on the inducer motor, the weak igniter, and already failed flame sensor. Average life span of these systems is 12 to 15 years this system is going on 11 years at this point I would consider options as far as replacing the system. Job complete

Came out to replace the furnace collector box. I disconnected the inducer motor and took apart the old collector box. I installed the new one and reconnected the inducer motor. I cycled the unit a few times and checked for leaks. No standing water or leaks found. Unit is operating normally at this time.

The furnace is making a very loud noise intermittently. I cycled the furnace multiple times and also let it run for awhile. I found the basement zone damper stuck closed and every time only the basement zone is calling for heat the furnace will whistle air passed all of the zone dampers causing the whistling noise throughout the home. Also, they must have tossed the frame for the humidifier pad. We will need to get them a new one. I will have the office quote over the zone damper and a new humidifier pad frame.

Performed furnace clean and tune; I cycled the system on and found that the system shut it’s self off I’m assuming dirty flame sensor, I then removed the burners and cleaned off the flame sensor, I then inspected the heat exchanger as well as did a powder test and did get blowback from 3 of the 5 cells, I then performed a combustion test verifying no CO in the airstream but did have slightly higher than normal levels of excess air. This system is currently operating at this time. This system is 20+ years old typical life span on these systems is about 15 years due to age, condition, and cost to repair I highly recommended replacement of this unit. Job complete

Was here for a call concerning a gas leak. We energies was here earlier. He flagged 2 leaks and shut down the furnace. I unscrewed the gas pipe and applied new pipe thread. Performed gas leak search. Didn’t find any leaks in the gas leaks at this time. Told the customer to monitor it for a couple of days. Recommended getting a furnace cleaning. No one has checked the furnace in a couple of years. Customer will call to schedule a furnace cleaning.
