We are extremely pleased with Luke's work, advice on our somewhat ancient gas furnace. He explained our options to proceed and answered all our questions. He has a great, engaging personality, which is very helpful when making difficult choices. One doesn't expect "to enjoy" a furnace inspection, but we did just that. Thanks for sending Luke our way.

My property managers scheduled Absolute Heating & Cooling, Inc to come check a leak with my wall AC unit. They called right away to get me on the schedule, arrived on time, and were very helpful in fixing the problem and showing me how to clean the unit to prevent it from leaking again. I would use them again and recommend them to others!
