Had an issue with the fuel oil furnace after some recent service, it suddenly started generating a lot of smoke and we had to turn it off. I called General and they had a technician here within the hour, and he fixed it quickly and effectively. Shout out to Gary for quick response time!

Clay H,

I had maintenance tech, Jake Kemp, come by my apartment to fix a hot water issue ive been having for roughly two months. He was very professional and friendly, and was able to fix the issue in a manner of 30mins (when other companies have been unable to fix the issue for months). To say I appreciate his timely and professional services is an understatement.

Ashley J,

They came out to give my wonky old oil furnace a yearly servicing. They were quick and professional, and I would recommend them to anyone seeking furnace services.
