Bass Heating & Air Conditioning, Huntley

Very disappointed in Bass Heating & Air Conditioning. I have been using them for several years and was extremely happy with the service. The last year I ordered general service and had to call out again as the heater went out. Bass came again told me it was the thermostat, purchased a new thermostat, tried to install it, wasn't the problem, called Bass back and Ben (great technician) figured out the problem -- should have been addressed with first and second visit. I ended up paying 2x for a 1x check. I let it go as things happen. Last week

Extremely professional, friendly and prompt service. Phoned with urgent and complicated issue, technician arrived shortly and was professional in every aspect of service. Work area around furnace left spotless. Technician explained the work done and was informative on running and maintaining system. I highly recommend Bass.

Bass mechanical is the only heating and air company that left me feeling confident in everything they told me. They are honest and knowledgeable. Reasonably priced and reliable I would highly recommend them to anyone in need of the services they offer. They have saved me from some hot days and cold nights!
