Called and asked for help on my air conditioning, was making weird noises. Told him the air was turning off and on but air was coming through. He says “so why are you calling us if its working”. Worst customer service ever. Would NOT RECOMMEND!!!

Two technicians, Jerad and Lionel (who was apprenticing), did maintenance work on our a/c while answering many questions from my husband and me about what we could do to continue to receive years of service from our older central a/c unit. Highly, highly practical and informative in their approach while responding to our questions with good natured professionalism.

Have had great service from Gamma. Very reliable. The work seems to be well done and a fair price.

Gamma Heating and Air Conditioning responded to our request for assistance immediately after we observed a slight water leak in our attic from a clogged evap pipe. Technicians arrived the next day to install an improved evap PVC pipe to keep excessive moisture away from the house foundation. Quick, top notch work, great response time. Thanks again for your fine, professional services.
