Garage heater installation cost in Calgary is $4,500 to $6,500 with us, as of September 2026. The same range applies to garage heaters in Airdrie.
The heater accounts for less of that spread than most people expect. What moves a quote up or down is the work around it: getting gas from the meter out to the garage, getting exhaust out through a wall or the roof, giving the unit power and a thermostat, and the permit and inspection behind any gas appliance.
What the garage heater installation cost covers
Your written quote breaks the job into lines: the heater, the gas line, the venting, the thermostat and controls, and the permit and inspection. You see every line before any work starts, and the quote itself is free.
A few things sit outside that range or depend on someone other than us:
- Insulating the garage. We don't do insulation, so it isn't in our price. It does change what size of heater you need, which comes up below.
- A new circuit, panel work or a feeder to the garage. That's licensed electrical work under its own permit, and it's scoped as its own piece.
- A larger gas meter. If the meter can't carry the extra load, the gas utility has to fit a bigger one. That step is the utility's, not ours.
Heater type and size
The output a garage needs is set by how fast it loses heat. Insulation in the walls and ceiling, the ceiling height, whether it's attached to the house or stands on its own, and how often the overhead door goes up all play into it.
More output means more gas, and more gas can mean a bigger line from the meter, which is the next section.
- Forced-air gas heaters use a fan to move warm air around the garage.
- Radiant tube heaters warm the floor, the vehicle and the people under them rather than the air, which suits tall or drafty spaces.
- Electric heaters need no gas line or vent, but they ask a lot more of the electrical supply.
Our garage heaters in Calgary page compares the three properly, including which kind of garage each one suits.
Insulate before you size
A garage that holds its heat may get by with a smaller heater, and it burns less gas every winter after. Insulation isn't a service we offer, but settle it before anyone picks a size.
Gas line distance and meter capacity
The gas line is the biggest single variable in the price: the length of the run from the meter, and whatever sits in its path.
Attached garage near the meter
The simplest case. When the meter sits on the garage wall or close to it, the new line is short and the route is obvious. This is usually a one-day job.
Attached garage on the far side of the house
When the garage is at the opposite end from the meter, the line normally crosses the house through the basement ceiling. A finished ceiling or ductwork in the way makes the route longer or means opening drywall, and the quote reflects the path the line actually has to take.
Detached garage with no gas
This is where the cost climbs. The line has to be buried between the house and the garage, so the scope includes:
- A trench to carry the line out to the garage
- Utility locates before anyone digs, requested through Utility Safety Partners, Alberta's locate service
- A riser and a shut-off valve at the garage wall
- Putting the yard back where the trench went
Trenching needs ground that isn't frozen, and the job usually takes two days. The trench is priced on the quote with the rest of the job.
Electric is sometimes the better answer here. If the trench would cut through the driveway, a deck or landscaping you'd rather keep, and you only heat the garage for the odd weekend project, an electric heater can make more sense than paying to bring gas out. Price both before you decide.
Meter capacity
Your meter already feeds the furnace, the water heater, and maybe a range and a dryer, several of them at once on a cold evening. Before a garage heater goes on, the load for the whole house gets checked, not just the new heater. Sometimes there's room to spare. Sometimes the gas utility has to fit a larger meter. The same question comes up with other big gas appliances, and our tankless water heater cost guide looks at it from that side.
Venting
Most gas garage heaters power-vent out through a side wall; some go up through the roof. Where it exits the outside wall is set by required clearances to the gas meter, doors, windows and air intakes, and it must clear the snow line on that wall. On a narrow lot, the vent position is often what settles which wall the heater hangs on.
The exact distances come from the heater's installation manual and the gas code, so they change from unit to unit. A longer vent run, or a route up through the roof, adds to the job.
Electrical
Gas units still draw power to run the blower, light the burner and work the controls. A usable circuit already close to the mounting spot keeps this part small.
An electric garage heater is a much bigger load. A detached garage running off a small feeder may not be able to carry one without an upgrade. Whichever heater you choose, the quote has to account for the electrical side, and any new circuit or upgrade is licensed electrical work with its own permit. It isn't a homeowner job.
Permit and inspection
In Calgary, a gas permit is required to install, alter or add to a gas system. According to the City of Calgary's plumbing and gas permit page, a homeowner can only take one out if they're an Alberta certified journeyman gasfitter who lives, or will live, at the address. For everyone else, the permit comes through the contractor doing the work.
Our gas work is done by Alberta-licensed gas fitters, and the permit appears as a line on the quote. The inspection takes place on a separate day from the install.
Thermostat and mounting
Mount the thermostat on an inside wall at about chest height, clear of the heater's discharge and well back from the overhead door. In the warm air stream it shuts the heater off too early; beside the door it reacts to every draft. A programmable or Wi-Fi thermostat is an option if you want the garage warm by the time you get out there.
Hang the heater where it won't foul the overhead door, its opener or a car lift, keeping the clearances its listing calls for. Aim a forced-air unit down the garage at its coldest end, not at the car parked beneath it.
What keeps the price down
- An attached garage with the meter on its own wall or close by
- A meter with capacity to spare
- A side wall close by with a clear spot for the vent
- An existing circuit near where the heater will hang
- An insulated garage that can get by with a smaller heater
What adds to the price
- A detached garage with no gas, and the trench to reach it
- A long line routed through finished ceilings or around ductwork
- A meter the utility has to upsize
- A long vent run or a roof termination
- A new circuit, feeder or panel work
- A programmable or Wi-Fi thermostat
Expect your quote to say which of these your garage has.
How long the install takes
With a short gas run to an attached garage, it's typically one day. A detached garage that needs a buried line usually takes two. Weather and locates can stretch either one.
What a good garage heater quote shows
Whichever quotes you collect, ours among them, look for these lines:
- Make, model and output of the heater
- How the output was chosen for your garage
- Gas line route and pipe size, and confirmation the meter was checked
- Vent route, and where the termination comes out on the outside wall
- Electrical scope, and who is doing that work
- Thermostat type and where it will be mounted
- Mounting position for the heater
- Permit and inspection
- Removal of an old heater, if there is one
- Manufacturer warranty and the conditions attached to it
If two quotes differ widely, compare the lines before the totals. Fewer lines usually means less included. If spreading the cost would help, you can pay through Financeit monthly payments.
The short version
With us, a garage heater install in Calgary runs $4,500 to $6,500 as of September 2026, and Airdrie installs cost the same. The gas line, venting, electrical, permit and controls move that number more than the heater does, and a detached garage with no gas is the biggest step up. Size the heater to how the garage loses heat, and get a quote that shows every part of the job.
