Excellent Service

Black-Haak installed my furnace and AC when I built my house. I've had them maintain and service my system ever since and have always been very pleased with their expert knowledge and quality of service. Their pricing is very fair and they are very honest up-front about the cost of things. I know I can rely on them and will be a lifetime customer! The technicians are VERY friendly and helpful, they are great to work with!

Completed installation of Aprilaire model 600 bypass humidifier. Mounted unit on the supply plenum and ran the 6” bypass to the return air drop ductwork. Connected a 1/4” copper water supply line between the hot water side of water heater and the Aprilaire. Ran a drain hose from unit to the floor drain.

Performed furnace start up; started by inspecting the exhaust and intake PVC ensuring all connections were secured, I then did a leak search on the gas line, next I cycled the system on and checked gas pressures did adjust gas pressure down to 3.5Inwc, also performed a combustion test verifying no CO in the airstream.

Performed furnace safety check; I cycled the system on and first performed a powder test on the heat exchanger and did receive blowback from all 3 cells, I then ohmed out the igniter, lastly performed a combustion test and did get high levels of CO and excess air in the exhaust. At this point this system is unsafe for operation. Due to age, condition, and cost to repair replacement of the system is recommended. Job complete second opinion scheduled with Dan F
