Gerald from Winnebago, IL

Asked for a quote to move the thermostat to another wall. $340.00 was ridiculous. I will be looking elsewhere for this service.

Outstanding workmanship at Axberg/Black Diamond Heating and Air Conditioning.

Paul D from Winnebago, IL

Black Diamond/Axberg Heating and Air Conditioning installed a brand new, gas forced heating unit in my house. The workmanship was outstanding. They went far and beyond normal workmanship. It was really a great job they did at my house right down to cleaning and removing the old heater I had. A+ job.
