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."

Why Should I Get a Humidifier?

Maintaining an ideal indoor humidity level is important. Proper humidity is necessary for respiratory health, as well as beneficial for skin and hair.

Humidity also keeps down dust and is necessary for homes that have wood furnishings, cabinets, and so on.

A central humidifier – one connected to your forced-air furnace – ensures that your entire home is kept at an ideal humidity level.

How Humid Should My House Be?

For homes in Calgary and area, you want to see between 35% and 55% humidity – less in the winter, more in the spring through early fall.
