About Flash Furnace
A locally owned Calgary furnace and air-conditioning company, built on honesty, pride in the work and fair prices.

How Flash started
Finding a good furnace company is like finding a good mechanic. After working for over 10 years in Calgary for other furnace companies, Aaron Moyer felt that things could be done differently. Some larger companies pushed technicians to bring in as much money as they could, without honesty and integrity. Tune-up calls were rushed, pressure sales were mandatory, and what the industry lacked was quality, pride and honesty. That is when Flash Furnace came to life.
Aaron took the leap and opened a company focused on doing it right for customers. Our honesty and work ethic are what make us stand out and keep us growing. More than 15 years later, with over 25 years in furnace repair, Flash Furnace is here to help with all your heating and cooling needs.
Qualified people in your home
Our technicians are registered gas fitters. That means your technician has been through school, has experience in the industry and has worked with all furnace types and proper gas codes. We always put your family's safety first.
We stand by our work
Flash Furnace takes pride in top-quality customer service. In the rare case where a repair needs to be reassessed, we don't charge additional fees. We always try to go above and beyond.
Making it affordable
Many people don't have the extra funds to fix or replace a furnace. We make it as painless as possible with monthly payment financing through Financeit. See how financing works.

Honest work, said in their words
Calgary homeowners have been calling Flash Furnace for more than 15 years. Here's what they say on Google.
I found Flash Furnace through my community Facebook page and am so thankful I did. My furnace quit working on Sunday and didn't want to risk waiting so called and Aaron was able to come out within a few hours. Thankfully it was a part he had in stock and was able to fix it quickly and efficiently. He was professional, helpful and did not try to pressure me with upsales. For friendly, professional and helpful services, try Flash Furnace, a NW, local, independent company.
