A Heated Garage Changes How You Use the Space All Winter
An unheated garage is often a space you avoid during Ontario winters. A properly installed garage heater transforms it into a comfortable, functional area for vehicles, workshops, home gyms, storage, and more.
GHQ Mechanical provides professional garage heater installation for residential and commercial properties. We assess your space, recommend the right heater type and size, handle gas or electrical connections, and complete all installations to manufacturer specifications and Ontario code requirements.

What a Heated Garage Actually Gives You
Most homeowners who install a garage heater say the same thing afterward: they wish they had done it sooner. Here is what the investment actually delivers across a typical Ontario heating season.
Vehicle Protection
- Helps protect batteries, fluids, and rubber components from extreme cold
- Reduces engine wear caused by cold starts
- Eliminates lengthy warm-up and defrosting times
Better Workspace Performance
- Keeps paints, adhesives, lubricants, and finishes within usable temperature ranges
- Improves battery performance for cordless tools and electric vehicles
- Creates a more comfortable and productive workspace year-round
Pipe & Equipment Protection
- Helps prevent frozen pipes and water line damage
- Reduces the need for seasonal winterization
Added Home Value
- A finished, heated garage is a desirable feature that can increase property appeal and resale value in Ontario’s climate.

Which Type of Garage Heater Is Right for Your Space
The right garage heater depends on your space, utilities, heating needs, and budget.
Natural Gas Heaters
- Cost-effective and powerful for larger garages
- Fast heating with lower operating costs
- Requires gas line installation and exterior venting
Propane Heaters
- Ideal for detached garages without natural gas access
- Similar performance to natural gas systems
- Requires a propane tank and certified installation
Electric Heaters
- No gas line or venting required
- Best for smaller garages or moderate heating needs
- Available in forced-air, infrared, and baseboard options
Infrared Radiant Heaters
- Heat people and objects directly
- Great for high-ceiling garages and workshops
- Available in gas and electric models
Forced-Air Heaters
- Heat and circulate air throughout the space
- Ideal for garages that need consistent, whole-room comfort
- Available in gas and electric configurations
We assess your garage size, insulation, ceiling height, and available utilities to recommend the best heating solution for your space.

Getting the Size Right Before Any Unit Is Ordered
Picking the right size garage heater is critical for comfort, efficiency, and long-term performance.
- An undersized unit runs constantly, wastes fuel, and struggles to heat the space.
- An oversized unit short-cycles, resulting in uneven heating and unnecessary wear.
- Proper sizing depends on garage size, insulation levels, desired indoor temperature, and local climate conditions.
We perform a detailed heat load calculation before recommending a unit, making sure you get the right capacity without overpaying for unnecessary heating power.

Why Venting and Clearance Requirements Matter in a Garage Installation
A garage presents specific installation considerations that do not apply in the same way to indoor HVAC equipment. Getting these right is not optional and cutting corners on any of them creates a safety problem that builds over time.
Venting
- Gas heaters must vent outdoors to remove carbon monoxide.
- Vent size and length must match the heater’s BTU rating.
- Poor venting can cause dangerous back-drafting.
- Horizontal vents need proper slope to prevent condensate buildup.
Clearances
- Heaters must be mounted above floor level to avoid flammable vapours.
- Required clearances from combustible materials must be maintained.
- The area below the unit should remain free of storage and obstructions.
Carbon Monoxide Safety
- Every garage with a gas heater should have a properly placed CO detector.
- We provide carbon monoxide detector placement guidance with all installations.

Commercial and Industrial Garage Heating
GHQ Mechanical installs garage heaters for commercial properties including automotive shops, fleet garages, warehouses, and industrial work bays across Hamilton, Caledonia, and Brantford. Commercial installations involve larger spaces, higher BTU demands, and in many cases multiple unit configurations to achieve even heat distribution spanning a large floor area.
Commercial garage heating considerations include:
- Multi-unit systems for large bays where a single heater cannot provide even coverage across the full floor area
- Makeup air requirements for spaces with high ventilation demands or paint and finishing operations
- Thermostat zoning for properties with separate bays or work areas that operate on different schedules
- TSSA compliance documentation for commercial properties subject to inspection requirements
- Coordination with existing electrical panels and gas supply infrastructure for high-capacity installations
