Excellent Service

My tech who came to tune up my furnace and fireplace was very knowledgeable and very friendly to my 2 yr old and my anxious dog. He was very professional and did an excellent job maintaining our products so they work properly when we need them. He left no mess and was very courteous and friendly. I highly recommend using Black-Haak for any of your heating or cooling needs.

Performed level 2 furnace cleaning. Rollout switch snapped on me during my inspection. Due to this being my fault, we will replace the part no charge. Burners and flame sensor are clean. Heat exchanger looks good. Only minor signs of wear. We will need to return ASAP as the customer is currently without heat. All we will have to do is replace the rollout and perform the combustion test. Everything else is done.

Came to investigate a no heat. The unit had a clicking noise coming from the inside. Heater was trying to light but failed. Checked gas pressure and had plenty. I also tried cleaning off the pilot to try and light to no success. We will return tomorrow to try cleaning the pilot again or possibly replace a part.

Installed April air 600 tested and ran humidifier. Went over with home owner operations of the April air 600. Completed a start up on the new Daikin furnace. Set the gas pressure at 3.5”. Adjusted the fan speed to achieve a 50* temperature rise through the furnace. The furnace is up and running efficiently.

Furnace clean and tune. Checked heat exchanger, found several heavy rust spots and deep etching where cracks are forming. Found burners very rusted and corroded. Flame sensor/igniter is very worn. Ventor motor bearings are worn. Checked for CO in airstream, none found at this time. High XS air found in exhaust indicating that there is some blockage in secondary heat exchanger. CO levels in exhaust are also elevated. Average life of this unit is 14 years, this system is 17+ years old and in very poor shape. Failure is expected. Second opinion recommended. System operating normal at this time, however several issues found. Job complete.
