Commercial RTU Services
Rooftop Unit Repair, Maintenance and Replacement in Ottawa
Packaged rooftop units combine several building-comfort functions in one piece of equipment. Our team looks at the complete unit before recommending a repair or replacement.
Rooftop Unit Repair and Diagnostics
We diagnose heating, cooling, airflow, ignition, electrical, control and ventilation problems in commercial rooftop units. The goal is to identify the cause, explain the repair and help you understand whether the issue is isolated or part of a larger equipment concern.
- No heat or insufficient cooling
- Airflow, blower and belt problems
- Ignition, burner and control faults
- Economizer, sensor and thermostat issues
Commercial RTU Maintenance
Maintenance should reflect how the property operates, how quickly filters load and whether the same unit provides both heating and cooling. We can build a practical service schedule around the equipment rather than placing every building on the same checklist.
- Heating and cooling inspections
- Filter, belt, drain and coil service
- Burner and operating-control checks
- Written observations and repair priorities
Rooftop Unit Installation and Replacement
When replacement makes more sense, we compare available rooftop equipment with the building load, existing curb and duct connections, gas and electrical requirements, controls, roof access and operating schedule.
- Replacement of aging packaged units
- Heating, cooling and heat-pump configurations
- Access, curb and connection planning
- Start-up, testing and future service
When the Equipment Needs Attention
Common Rooftop HVAC Problems We Investigate
A rooftop unit can continue running while comfort, airflow or energy use gradually gets worse. Early diagnosis may give you more repair options and more time to plan around business hours.
- Heating or cooling that cannot reach setpoint
- Uneven temperatures across the property
- Repeated lockouts or control errors
- Unusual noise, vibration or cycling
- Water around the unit or blocked drains
- Rising operating costs without a clear reason
- Outdoor-air or economizer problems
- Frequent repairs on an aging unit

The AirZone Advantage
Commercial Expertise With Responsive Local Service
AirZone serves both residential and commercial customers. That combination gives our commercial clients two important advantages: strong equipment buying power and a customer-service system built around clear communication, written quotes and accountability.
Our commercial team brings experience with rooftop units, heat pumps, boilers, mechanical rooms and building controls. Our office and service structure keeps the work organized from the first call through installation, repair or maintenance.
Because our residential division purchases a high volume of equipment, we can offer aggressive commercial rooftop unit pricing without giving up the local support businesses expect after the installation.
Commercial RTU Replacement
Planning a Rooftop Unit Replacement
A rooftop replacement involves more than ordering a unit with the same tonnage. We review the existing installation and show the related work in the quote before the project is scheduled.
Repair Today or Plan the Replacement?
Not every older rooftop unit needs immediate replacement. We consider the condition of the equipment, repair history, parts availability, operating costs and how critical the unit is to the property.
If repair remains reasonable, we will explain the work. If replacement deserves consideration, we can provide options and help you plan the project before the next major heating or cooling demand.

Commercial Rooftop HVAC Questions
Frequently Asked Questions About Rooftop Units in Ottawa
Here are straightforward answers about RTU service, maintenance, brands, replacement planning and pricing.
What is a commercial rooftop unit?
A commercial rooftop unit, often called an RTU, is packaged HVAC equipment installed on the roof of a building. Depending on the configuration, one cabinet may provide gas heating, electric cooling, heat-pump operation, airflow and outdoor-air ventilation for the space below.
Does AirZone repair commercial rooftop units in Ottawa?
Yes. AirZone provides professional rooftop unit service and repair throughout the greater Ottawa area. We diagnose heating, cooling, airflow, ignition, electrical, control and ventilation problems in packaged commercial equipment.
Which rooftop HVAC brands does AirZone install and service?
AirZone installs rooftop equipment from York, Carrier, Lennox, Trane, Daikin and Amana and services many other packaged-unit brands. Service depends on the equipment type, age, condition and parts availability, so sharing the model number helps us confirm the request.
How often should a commercial rooftop unit be maintained?
Most rooftop units should be inspected before the main heating and cooling seasons. Properties with long operating hours, heavy filter loading, demanding indoor conditions or critical equipment may need more frequent visits. We can recommend a schedule after reviewing the unit and building use.
When should a rooftop unit be replaced instead of repaired?
Consider the unit’s age, overall condition, repair history, parts availability, operating costs and importance to the property. A single repair may still make sense on an older unit, while repeated failures or a major component problem may justify comparing replacement options.
Can AirZone replace an existing commercial rooftop unit?
Yes. We inspect the existing installation, compare replacement equipment and prepare a written scope. The plan can include curb and duct connections, gas and electrical work, controls, removal, roof access and crane coordination when required for the project.
Does AirZone offer commercial rooftop maintenance plans?
Yes. AirZone offers flexible commercial HVAC maintenance plans based on the equipment, filter requirements, seasonal operation and access conditions of the property. Planned service can include inspections, filters, belts, drains, coils, burners, controls and written equipment observations.
Why can AirZone offer competitive rooftop unit pricing?
AirZone purchases a substantial volume of heating and cooling equipment for both residential and commercial projects. That buying power, combined with relationships across several major brands, helps us offer aggressive RTU pricing while keeping installation and future service with one local company.
