A Unit Space-Saving Design

By combing a furnace and hot water heater, the syncFURNACE™ is able to operate highly efficiently and use significantly less space than a traditional furnace + hot water heater setup.

Built by Calgarians

Unlike most furnaces and air conditioning systems, which are manufactured in the USA or overseas, the syncFURNACE™ is not just Canadian-made, but made right here in Calgary.

We love supporting local innovators!

Your Satisfaction is Our Goal

A Sample of our Real Customer Reviews

"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."

How Quickly Will You Be Here After I Book an Appointment?

We will arrange a convenient time for us to come by, inspect your home and installation site, and then provide you with a proper estimate that includes all labour and parts costs. This quote will include the removal of your existing furnace and hot water heater (if you haven’t already done the legwork for us).

How Long Does a Install Take?

Generally, a syncFURNACE installation is an 8-hour job, though factors tied to the installation area may influence this.
