Garage Heater Installation & Service — Licensed Gas Fitters
Whether it’s a new installation or a heater that stopped working mid-winter, we handle both sides. Every job includes a BTU load calculation, proper gas line tie-in by a licensed gas fitter, and an Alberta permit where required.

01 Garage Heater Installation
New Garage Heater Installed — Sized for Your Space, Not Guessed
The wrong BTU rating is the most common garage heater mistake. Too small and it runs constantly without reaching temperature. Too large and it short-cycles and wastes gas. We calculate the exact requirement for your garage before recommending any unit.
02 Garage Heater Repair & Service
Garage Heater Not Igniting? We Diagnose and Fix It — All Brands
Most garage heater failures come down to a dirty igniter, a faulty thermocouple, or a blocked burner, all fixable same day. We carry common parts on the truck and service all major brands regardless of who installed it.

What’s Included on Every Garage Heater Installation
These aren’t add-ons or upsells, they’re part of every job because cutting corners here causes failures down the road.
BTU Load Calculation
We calculate the exact heat requirement for your space based on square footage, ceiling height, insulation, and door exposure. No guesswork.
Thermostat Wiring
Thermostat installed and programmed so you control your garage temperature without manually cycling the unit.
Gas Line Tie-In
A licensed gas fitter connects the unit to your existing gas line and pressure-tests before firing up. Required by Alberta code on every job.
CO & Safety Inspection
Carbon monoxide test and full safety check completed before we leave. Non-negotiable on every gas appliance job.
Overhead or Wall Mount Install
We handle the full mechanical installation – brackets, hanging, positioning for optimal heat distribution in your specific space.
Alberta Permit Filed
We handle the permit application as part of the job. Every gas installation in Alberta requires one – we take care of it.

Garage Heater FAQ

Explained everything that needed to be done and was completed quickly.Posted on Google David CTrustindex verifies that the original source of the review is Google. Replacing a furnace is stressful, but Rodger and his team made the whole process seamless. Elod was awesome across the two days of work, and Harman, Rajdeep, Oleksandr, and the rest of the crew were just as great to deal with. They even lifted our filter racks off the ground so replacing filters is way easier now, and while working on the roof, they noticed a cracked tile elsewhere and gave us a friendly heads-up to fix it before bad weather—really appreciated that extra attention to detail! Everyone was punctual, super respectful of our home, kept everything clean, and answered all our questions without rushing us. Solid 5-star team—can’t recommend them enough!Posted on Google Nancy NichollsTrustindex verifies that the original source of the review is Google. Very customer service oriented.

I had a humming noise coming from the furnace when the A/C kicked in. I couldn't find the source but the tech from Rodger That knew to check how the blower fan motor was connected and solved it with a different fan speed. Super knowledgeable. Would reccomend these guys.
