Smoke alarm issue




Pleased with how quickly you came....and my dog is very happy he isn't hearing that noise any more! Service was professional and thorough. Mike checked the other detectors as well and took out the locking pin so that I can change the batteries myself if need be.

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!

Troubleshot smoke detectors beeping. Detectors were giving low battery signal. Removed batteries and checked them. They were still reinstalled and ensured proper contact with the terminals. Detectors stopped chirping.

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 furnace on and checked gas pressures, as well as performed a combustion test verifying no CO in the airstream. Holly did request that we replaced the #35 aprilaire water panel. I did notice the damper for the humidifier was in the summer position because of this the system was not operating. This system is currently operating normal at this time job complete

Performed furnace clean and tune; inspected the exhaust and intake PVC ensuring all connections were secured, I then removed and cleaned the burners along with the flame sensor, next cycled the system on and checked gas pressures, as well as performed a combustion test verifying no CO in the airstream. This sytem is currently operating normal and heating at 50 degrees at this time. I did take a snapshot of the systems blower wheel this picture shows a substantial amount of dust on the wheel this could potentially cause up to 30% reduction of efficiency on the system I did include an estimate for an electronic air cleaner to bring these levels of dust down in the home.

This system is currently operating normal and heating at 57 degrees at this time.

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
