No heat, intermittent ignition or a heater that keeps shutting down? YYC Mechanical services rooftop heating, commercial furnaces, unit heaters and make-up air for Calgary businesses.
Heating Help for Offices, Shops, Restaurants and Managed Buildings
A heating failure can affect one room, one tenant or the whole building. We look at the heat call, equipment operation, airflow and controls together to understand why the space is cold. We explain what we find, what can be repaired and what needs further planning.
No Heat or Ignition Failure
Burners that do not light, heating stages that fail to start, flame-sensing problems and intermittent lockouts.
Uneven Heating or Weak Airflow
Cold zones, a unit running without reaching setpoint, supply-fan problems, belts, filters and control issues.
Repeat Shutdowns
Heating that stops during busy periods or cold weather, nuisance trips and faults that return after a reset.
What We Check During a Heating Service Visit
The checks depend on the model and the fault. Typical areas include:
- Thermostat calls, schedules, sensors and control signals
- Ignition sequence, flame sensing and recorded fault codes
- Fan operation, belts, filters and airflow restrictions
- Heating components and accessible equipment condition
- Safeties and interlocks relevant to the shutdown
- Operation after repair and any remaining concerns
What to Have Ready When You Call
- Site address, affected areas and access contact
- Equipment type and model, if you already have it
- Whether the fan runs and whether the fault is intermittent
- Fault codes or photos available without opening the equipment
- Rooftop-access requirements and tenant operating hours
Call for an urgent no-heat problem so we can discuss dispatch directly. General online enquiries are suitable for planned service and questions.
Call 403-660-9309Plan Heating Maintenance Before the Next Cold Spell
A pre-season visit helps identify worn belts, restricted airflow, ignition problems and controls that need attention. Visit frequency depends on manufacturer guidance, equipment condition, use and site environment. We can include heating and cooling equipment in one commercial maintenance plan.
Commercial Heating Questions
What commercial heating equipment do you repair?
We service heating in gas/electric rooftop units, commercial furnaces, unit heaters and make-up air systems. Share the equipment model and symptoms so we can confirm the service requirements before the visit.
Can you help with an after-hours no-heat call?
Yes. We offer 24/7 emergency HVAC service for failures affecting building comfort or operations. Call 403-660-9309 to discuss the equipment, affected areas, urgency and access; arrival and repair timing depend on dispatch and parts availability.
Why does our heater work sometimes and then lock out?
Intermittent heating can involve ignition, flame sensing, airflow, controls or a safety fault. The lockout code and when it occurs help the technician investigate. Repeated resets can hide the fault and do not resolve its cause.
Can you work with our property manager or multiple tenants?
Yes. We can coordinate equipment access and service scheduling with the site contact or property manager. Tell us which spaces are affected, any access restrictions and whether work must fit around tenant operating hours.
Should we repair or replace an older commercial heater?
We consider the fault, equipment condition, parts availability, repair history and suitability for the space. A worn motor or ignition component can have a different repair outlook from major deterioration or repeated failures. We explain the findings and options before recommending replacement.
