What the work covers
Six areasUnit and radiant tube heaters
Suspended unit heaters and infrared tube systems selected according to the building load, ceiling height, bay layout and door activity.
Burners and combustion
Ignition systems, burners and gas pressure tested, with combustion readings recorded where applicable.
Venting and safeties
Venting, heat exchangers, limit switches, rollout protection and other safety controls inspected before the equipment is returned to service.
Fans, motors and components
Blower motors, fan assemblies, bearings, belts, ignition components and controls diagnosed and replaced as required.
Controls and zoning
Thermostats, staging and zoning configured so occupied areas receive heat without overheating unused sections of the building.
Heat distribution
Air movement and destratification reviewed in high-ceiling spaces to reduce heat accumulation above the occupied area.
What it costs
Montreal & West Island, 2026Commercial service calls start at $500. Commercial rates can differ based on the equipment, access requirements and scope of work. We explain the applicable charges when arranging service.
You receive a written price before repair work begins. Installation pricing depends on heater capacity, mounting height, venting, gas piping, electrical requirements and lift access. Maintenance is quoted separately according to the equipment and required visit frequency.
Questions buyers ask
Once a year, before the heating season. Burner, heat exchanger, venting and controls, with the combustion readings recorded.
Warm air collects at the ceiling. That is a placement and destratification problem far more often than a capacity problem.
Yes. For equipment above 8 feet, we arrange scissor lift access and coordinate with your team to ensure there is enough clearance and space to complete the work safely.
Tube heaters suit spaces with big door openings because they heat objects rather than air. Unit heaters suit enclosed bays. We will say which fits yours.
Usually yes. Splitting a shop into two or three zones is the cheapest heating saving available in most buildings.
Yes. We service and repair make-up air units, including burners, fans, filters, belts and controls. We also check how the unit works with your exhaust system to maintain proper airflow and building pressure.
Yes, including the venting and the gas connection. Older units are often cheaper to replace than to keep patching.
Emergency service available seven days a week. Our phones are answered every day.
