Fast service, quality service!
Aaron - Brookville, PA
Our furnace went out and after calling multiple companies, Gary & Sons was the only one willing to come look at it in a timely manner. They had a new furnace installed for us within a couple days which was much appreciated especially in the dead of winter. They were on time, professional, and cleaned up after the job was done. Will definitely recommend them to friends and family!

Really disappointed
Jeffery - DuBois, PA
Have been a customer for about 14 years. The last few years service has really declined. Having a heat pump installed did not go well. Very poor installation that resulted in two trips by technicians to remedy. Installed air filters system which has not resolved issues we were told it would. Had technicians to our house at least half a dozen times this year with frustrating results until we were told the heaters “board” was the problem and replaced. You didn’t charge us labor we were told but what about the other money we gave you previously to resolve same problem. So it looks like you lost a good customer.
Response from Gary & Sons, Inc.:
Jeffery, Thank you for sharing this feedback about your concern with the heat pump. We have a solution and have been trying to reach you the past few days by phone and email to discuss. Please give us a call at your convenience!
