"I had a query about a sound I heard with my furnace and David was SO friendly and SO kind! He walked me through a few things I could try and look into myself - learned some things I never knew! He also gave me great information about other products and services available. If you want to work with a great human, call David!"

Sandra McQueen

"I was having problems with the heater in my garage (It wasn't working!) and called on David. He came out within a few days, was on time, and did a great job. He not only fixed the problem but also identified a couple of others and suggested I call the appropriate services so as to prevent future damage to my garage/roof. He did a great job, went above and beyond, and was professional and helpful! I would definitely call on him again for future needs!"

Lorna Stuber

"I used David with Lancelot Furnace for a second on a few of my installs and have had great luck with his quality of work as well as his professional behavior. Would definitely use him again."
