I had David come out and service my Furnace after I was told there was a good chance I would have to replace it from a house inspector. After David came out he quickly found the problem and was able to fix the Furnace at a fraction of the cost and we noticed a big difference in how the furnace was operating afterwards. I would highly recommend Lancelot Furnace to anyone who needs an honest professional that takes pride in his work.

My furnace needed a repair just as the weather was turning. David was quick to respond, was very economical, and did high quality work. I appreciated his care for my home and my furnace, as well as how easy the entire process was from booking to payment.

David was excellent! He came the same day he was contacted and did a thorough job of checking everything, explaining as he went and stayed until he was sure it was working properly (unlike the furnace company I tried last year who never fixed the problem). I felt confident that the issue was resolved and would highly recommend him to others. He does a thorough job for a fair price.

What an excellent service! We had a fan speed problem with our furnace and had tried a larger firm, first, and was told they could not solve it without a full replacement of the motor or computer board or both; we then brought in Lancelot. He worked the problem, calling the manufacturer and ultimately solving our problem at a very minimal charge. We highly recommend this company for its friendly, resourceful and inexpensive service!

Excellent quick and cheap service! Owner operator who actually cares. Was thorough and talked me through what all the parts of my furnace were ( I like to watch ) perscribed a list of extra parts that would be helpful and convenient for the next time the furnace goes down. Anyways super friendly, talked well and had the service every customer wants to receive.

Lancelot Furnace Ltd. is by far the best furnace company I have dealt with in my life! Before I was ready to commit to an inspection, David talked to me on the phone to do basic troubleshooting and then followed up with me a few days later to see how things are. Once the temperature really dropped and I needed help, David came over and looked at the furnace and the thermostat. My home is a trailer home, with a slightly different type of layout than most places. David is the first person ever to enter my home and be knowledgeable about the furnace type and how it works in a trailer home. Now my home is back to being warm and toasty on a cold day and my pipes are no longer freezing. David is knowledgeable and passionate about keeping customers warm. I highly recommend Lancelot Furnace Ltd. to rescue you!

I had a noisy old furnace that was keeping people awake in my house. Lancelot Furance came in and fixed the problem in no time. Even though it is an old furnace he never tried to convince me to replace it, in fact he told me to keep it going as long as I can. Very personable, fair rates and the furnace has been working great since he fixed it so quality work. I will be using Lancelot if I ever do decide to replace ol' faithful.

David at Lancelot furnace is one of the most customer service oriented people i have had the pleasure of working with. I had David out to help me with a project that i knew would be beyond his scope of services and he still went the distance to set me up with the right people and businesses despite there being no gain involved for Lancelot Furnace. Id have no problem letting David into my home in the future. Thankyou David!

I had the misfortune of having my furnace stop working earlier this year during one of our winter’s cold snaps. When I called Lancelot Furnace Ltd, they managed to fit me in at the end of a very busy day to ensure that I had heat for my home and my family. Not only did the owner David fix the broken furnace, he was able to troubleshoot the problem over the phone with me to ensure he had the right parts available when he arrived. On top of this, he also took the extra time to inspect the unit to ensure there were no other issues waiting to surprise us. I highly recommend David and Lancelot Furnace for your home heating (and/or cooling) needs.
