Why Niagara picks us

Three decades of getting it right
the first time.

We are not a national franchise. We are a Dunkirk Road shop with the same family at the helm since 1994. The technician who installs your furnace is the one who comes back to tune it up.

We pick up at 2am

Niagara winters are brutal. When your furnace dies in February we have a technician on the road within the hour - not the next business day.

TSSA-licensed gas technicians

Every technician is TSSA certified for gas work, ESA endorsed for electrical, and fully insured. Your install passes inspection the first time.

Flat-rate pricing up front

You see the full price before we start the job. No surprise add-ons. No "while we are in here" extras. No hourly rate creep.

Family-owned since 1994

Three decades serving St. Catharines, Niagara Falls, Welland, Thorold, Pelham, and Grimsby. Most of our work is repeat customers and their kids.

the headache.

Furnace died on a Sunday morning at minus 18. Called Mr. Furnace at 8am, had a technician at the door by 10:30, and the house was warm again before lunch. Fair price, no upsell, real professionals.

Homeowner, Old Glenridge - St. Catharines

Replaced our 22-year-old air conditioner last spring. They explained the SEER ratings in plain English, gave us three quotes at three different price points, and showed up exactly when they said they would.

Homeowner, Niagara-on-the-Lake

We have been customers since the early 2000s. Same family, same standards, same fair pricing. They installed our furnace, our AC, our water heater, and now they tune everything up every fall.
