Maintenance First
planned support that protects uptime
When a rooftop unit affects heat, cooling, ventilation, or the building’s ability to operate, Arctic Air gives commercial property teams a direct path to qualified field support.
RTU fundamentals
What a rooftop unit does in a Calgary commercial building
An RTU packages heating, cooling, and ventilation into one rooftop system. In Calgary, those units work through -30°C winter conditions, +30°C summer heat, and occasional wildfire-smoke events, so filters, airflow, heating components, cooling circuits, and controls all need attention at the right time.
Preventative service

A scheduled visit can cover filters, belts, economizer operation, refrigerant charge, heat exchanger condition, dampers and actuators, condensate management, electrical and controls verification. Timing the work before the heating and cooling seasons helps reveal risk before demand and weather make a minor issue urgent.
Service planning
Rooftop unit Calgary service coverage
Many commercial properties rely on several RTUs, and portfolio clients may have units across multiple sites. Arctic Air can organize maintenance by unit and season, record what needs attention, and give maintenance-plan clients priority response when an issue becomes urgent.
Diagnostics and repair
Rooftop unit repair Calgary
Property managers often notice hot or cold spaces, comfort complaints, poor airflow, leaks, unusual cycling, or a unit that will not recover. The underlying cause may be a failed economizer that creates simultaneous heating and cooling, a cracked heat exchanger, refrigerant leak, seized damper actuator, compressor or contactor failure, water ingress, or a controls problem. Arctic Air diagnoses the cause before recommending the next practical step.
Replacement and projects
Rooftop unit installation Calgary
A rooftop-unit change-out starts with the real building load and occupancy, not a generic equipment swap. Arctic Air plans around existing curbs and ductwork, roof and crane access, tenant disruption, safe staging, and commissioning so the replacement performs as intended when the building needs it.
Why Arctic Air
Why property managers keep Arctic Air on RTU service
Arctic Air has been Calgary-owned for more than 20 years, with an in-house team of journeyman and advanced-apprentice technicians. Property teams get one point of contact, a one-year parts warranty, and commercial service that stays connected to the rest of the building’s HVAC needs.
Rooftop unit questions
Practical answers for commercial RTU planning
These are the questions property managers and facility teams commonly ask before a seasonal visit, urgent repair, or equipment replacement decision.
How often should commercial rooftop units be serviced in Calgary?
Most Calgary commercial rooftop units benefit from scheduled seasonal service before heating and cooling demand peaks. Buildings with long operating hours, demanding ventilation loads, or several RTUs may need a maintenance plan tailored to the equipment, filters, belts, controls, and tenant schedule.
What does a commercial rooftop unit service visit include?
A rooftop unit service visit can include filter and belt checks, economizer operation, refrigerant charge, heat exchanger condition, dampers and actuators, condensate management, electrical components, controls verification, and a clear report on any repair or replacement risk.
Can Arctic Air service multiple rooftop units across a portfolio?
Yes. Arctic Air can organize rooftop-unit maintenance around multiple units at one site or across a commercial portfolio, with service records and seasonal planning that help property teams see the condition and priority of each asset.
How fast is emergency rooftop-unit response?
Arctic Air provides 24/7 emergency service for commercial clients. Response timing depends on the location, operating conditions, safety requirements, access, and the nature of the failure, but the team will assess the issue, communicate the next step, and work to restore safe operation as quickly as practical.
