Commercial Rooftop
HVAC Units Toronto
Packaged RTU installation, replacement, and service for retail, office, and light industrial buildings across the GTA.
Commercial Rooftop Systems We Install
From single-zone retail units to multi-zone light industrial systems, we handle full RTU projects including crane work, curb adaptation, and controls.
Gas/Electric Packaged RTU
The most common configuration for Toronto commercial buildings. Gas heat exchanger for winter, electric compressor for summer — all in one sealed rooftop cabinet. Carrier, Lennox, York, and Trane available.
Heat Pump RTU
All-electric rooftop heat pumps for buildings with gas restrictions or sustainability targets. Efficient down to -15°C with low ambient kits. Ideal for new construction and electrification retrofits.
Rooftop Air Handlers
Custom-matched rooftop air handlers for existing DX coil systems, chilled water applications, or 100% outside air ventilation. Includes economizer, IAQ sensors, and BACnet integration on request.

Commercial RTU Questions
A commercial RTU lasts 15–20 years with proper maintenance. Regular filter changes, coil cleaning, and annual preventive maintenance inspections are the biggest factors in lifespan. Units run to failure without maintenance often fail at 8–10 years.
A standard packaged RTU replacement for a small commercial space (3–5 ton) runs $8,000–$18,000 installed. Larger units (10–25 ton) for retail or light industrial applications run $20,000–$50,000+. Cost depends on unit size, efficiency rating, crane requirements, and curb/duct modifications needed.
A packaged RTU has all components in one self-contained unit on the roof. A split system has the condenser outside and the air handler inside. RTUs are preferred for flat-roof commercial buildings because they save interior space, simplify maintenance access, and consolidate all mechanical equipment on the roof.
Yes — a gas/electric packaged unit is the most common commercial RTU configuration in Canada. It uses a gas heat exchanger for heating and a compressor-based refrigeration system for cooling, all in one rooftop cabinet.
Yes. RTU installation requires mechanical permits and must be done by TSSA-registered contractors. We handle all permitting and inspections as part of the project.
Yes. We service and replace commercial RTUs in Toronto, Thornhill, Richmond Hill, Markham, Vaughan, North York, Scarborough, Etobicoke, Mississauga, Brampton, and surrounding areas. We work with property managers, landlords, and business owners throughout the Greater Toronto Area.
Yes. We offer annual and semi-annual maintenance agreements for commercial rooftop units. Regular PM — filter changes, coil cleaning, refrigerant checks, combustion analysis — extends unit life significantly and catches small problems before they become expensive failures.
Yes. We coordinate the full scope of commercial RTU replacement: equipment procurement, crane rental, rigging, curb adapter fabrication if needed, duct connection, and commissioning. One contractor managing the whole project — not three separate trades to coordinate.
