Prompt Reliable Service

I read online where the service is the most important item when selecting heating and air conditioning. I always have experienced great service from Black Haak and am happy I selected them. They are always prompt and do quality work at reasonable costs.

Great Service, Great Job!

Our furnace is over 13 years old, when it comes to maintenance and cleanings we always rely on Black-Haak! Their service personnel are the BEST in the business! Their service technician Anthony Nieland came in today and did an excellent job cleaning and maintaining our furnace. He explained everything he did in language I can understand. Thanks Anthony for your hard work and professionalism today!

Performed the level 2 fireplace cleaning. I wiped away dust in the upper and lower compartments. Inspected the logs. Cleaned the pilot and the glass. Replaced the embers. Cycled the fireplace. No failure during my visit. Fireplace may have kicked out due to wind or snow in the venting. I checked the chute and didn’t find any debris. Unti is heating properly.

Furnace clean and tune. Cycled system. Checked heat exchanger, ok. Checked, removed, and cleaned burners and flame sensor. All ok. Igniter tested normal. Checked and adjusted gas pressures to maximize efficiency. Checked and tested furnace safety systems. Preformed combustion test and found normal levels in exhaust. No CO found in airstream. System operating normal at this time. Customer is having issues with thermostat and the WIFI settings. It disconnects from Honeywell program a few times. Thermostat is operating normal from what I can test. It appears that the issue may be from the app side or Honeywell side of the process. System operating normal at this time. Job complete.

Furnace is intermittently working. Igniter is igniting but gas valve does not open. Unable to determine if its gas valve or circuit board. Ran tests and gas valve did relieve voltage but could not get fault to repeat. Separate issue : Inducer motor also needs replacing Follow up second opinion with Dan Fox

Furnace clean and tune. #1. 3079. Cycled system. Checked heat exchanger. Found all chambers extremely worn and rusted. Deep etches found and cracks starting to form. Checked, removed, and cleaned burners and flame sensor. Checked and cleaned sparker. Checked and tightened electrical connections and clamps. Cleared drain lines. Found ventor motor bearings are worn. Leaks from transition assembly, possible cracks in assembly. Found evidence of water damage in blower and burner compartment. Checked and adjusted gas pressures to maximize efficiency. Preformed combustion test. Found CO levels very high. Levels were between 115 and 125. Also found XS air levels near 200. This is a very strong indication of secondary heat exchanger blockage and/or primary failure. Average life expectancy for this unit is 14 years. This system is over that expected time line and is in very poor condition. Furnace clean #2. 2003. Cycled system. Checked heat exchanger. Found all chambers are worn, rusted and ha

Performed the level 2 boiler cleaning. Customer said they were having issues with pipes rattling. I was unable to get the pipes to do so during ,y visit. The heat exchanger is very rusty and chipped. Pilot is showing signs of wear. Average life of system is 12-15 years. Unit is currently 14+ years old. Due to age, condition, and cost for repairs, I recommended a second opinion to review options. We will call to schedule.
