Whole House Generator Maintenance in McHenry, IL 60051

“The technician serviced the generator, furnace, AC and humidifier.
It was both general maintenance, repair of a defective part, and installation of a new thermostat.
Although it took a long time, the work was accomplished and then I got assistance on hooking up to the new wifi thermostat. It seems easy, but time will tell!”
