Nice follow-up from Black Hawk, great service from Julian.

The service call was on time and well done. Julian was efficient and personable. Should have advised me about servicing the AC at extra cost prior to doing it. It was OK because it should be done but a heads up would be nice.

Happy with the work, and the workers!!

Although it started a little shaky, reason for only 4 stars, it ended up being pretty good. Guys were professional and truly experienced. They did excellent work. Would recommend to anyone!!

Completed installation of an Aprilaire 700 and 16x25x1 electrostatic filter. Mounted the humidifier on the furnace plenum and the control on the return air ductwork. Wired the control to the furnace and to the humidifier. Ran a drain hose to the floor drain, and a water line from the water heater to provide water for the humidifier. Re-worked the return air drop to accommodate a new filter rack for the electrostatic filter. Left old filter unit in the mechanical room per request of the customer. Run tested the equipment and all is operating as it should. Thank you for choosing Black-Haak Heating and Electric. Please take a moment to fill out our online survey.
