Brad came to troubleshoot the boiler that the office had been alerted via our boiler connected to the web. He found the problem and fixed it. At this point I mentioned we had an issue with the AC maintaining temperature. Brad fixed the AC immediately. Great professionalism and knowledge.

Completed gas furnace replacement. Disconnected and removed the old furnace. Set new furnace on same pads and reconnected the gas, electric, pvc venting and the ductwork. Installed a new T6 wifi compatible thermostat and connected it to the furnace. The office will contact you to set up a time to have a service tech come by and do furnace start up at your convenience. Thank you for choosing Black-Haak Heating and Electrical. Please take a moment to fill out our online survey.

When I arrived, ac was running and cooling. I inspected customer installed contactor. Contactor was installed correctly. Checked wiring and operation, system is operating normal at this time. Customer informed me that he hooked low voltage wires up on same side of contactor and blew the low voltage fuse on furnace. When he replaced fuse, his Nest thermostat showed an error of ac equipment not connecting to thermostat. This error does not allow him to access his thermostat options. Checked for correct wiring on thermostat terminal strip. System is wired correctly. On line app shows that thermostat is off line. I quoted T6 WIFI(350.00+tax) and Lyric thermostat (448.00+tax), he is not interested in having us replace thermostat. He will get new thermostat and wire it himself. System is operating normal at, with exception of thermostat, at this time. Job complete.

Performed the level 2 package cleaning. Furnace: The unit is showing signs of wear due to age. There’s rust in the upper compartment from water damage in the past. Heat exchanger is also rusting out. No cracks located in the heat exchanger and it also passed the smoke test. Excessive air was a little high in the exhaust, however, it is not at a concerning level at this time. CO in the exhaust was at normal levels and there was no CO detected in the air. This furnace is currently safe to operate, however, due to age and condition, we cannot gaurantee the future life expectancy. AC: There were no refrigerant leaks detected durning my inspection. The unit is clean and operating properly. Due to age and condition, we cannot gaurantee the life expectancy in the future for this unit as well. It is still running as it should.
