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.

I would recomend Black Haak Heating Service. Dan was very professional. He also did a good job of explaining the several things that are problematic with our older furnace.

Performed furnace start up; inspected the exhaust and intake PVC ensuring all connections were secured, sniffed the gas line for possible leaks, as well as cycled the system on and checked gas pressures did find that 1st stage would not adjust we’ll have to return to replace the gas valve, also performed a combustion test verifying no CO in the airstream. This system is currently operating normal and heating at 42 degrees at this time. Lastly I wanted to make note I did notice on the maintenance sticker that a previous company had added 8oz of R22 refrigerant to the AC sytem back in 2007 but did not locate nor fix any leaks. I did a refrigerant leak search on the indoor coil and did find a couple solid indicators of a leak on the system. This is a concern for me because that coil sits right above the heat exchanger on this brand new furnace and an AC sytem that is low on charge could form a solid block of ice during the summer months meaning that the condensation would fall on the he

Came out to perform a furnace check. After taking the furnace apart, I found it was very dirty and recommended a full clean and tune. Customer accepted so I performed a preferred customer clean and tune. Burners and flame sensor are starting to rust. Heat exchanger is starting to chip and rust. Inducer motor bearings are starting to sound worn out as well. The furnace is roughly 20+ years old. Due to age, condition, and cost to repair, second opinion is recommended. Failure is expected in the near future.
