Choose the Right Rooftop System for Your Building
Commercial rooftop units are available with different heating-energy configurations. The right choice depends on your existing utilities, building requirements, operating priorities and local climate. Explore our gas/electric, all-electric and hybrid rooftop systems below.
Gas Heat / Electric Cooling Rooftop Units
Gas/electric packaged rooftop units combine natural-gas heating and electric air conditioning in one self-contained system. They are a practical replacement option for many commercial buildings that already have natural-gas service and require dependable heating performance during cold Canadian winters.

Carrier WeatherMaster 48GE Light Commercial Gas Heat/Electric Cooling Packaged Rooftop Unit
York Sunline ZE Series Single Package Air Conditioner / Gas Heat Rooftop Unit
All-Electric Rooftop Units
All-electric rooftop units provide cooling and electric heating without on-site fossil-fuel combustion. Depending on the selected equipment, heating may be provided by a high-efficiency heat pump with optional electric resistance backup, making these systems suitable for electrification and energy-efficiency projects.

Dual-Fuel / Hybrid Rooftop Units
Dual-fuel or hybrid rooftop units combine electric heat-pump operation with supplemental gas heating. The system can use electric heating during suitable operating conditions and switch to gas when additional heating capacity is required, offering a balance between electrification, operating flexibility and cold-weather performance.

FAQ
Rooftop Unit Selection and Quotation FAQ
How do I select the correct rooftop unit?
Start with the cooling load and the airflow the system needs. Then confirm the electrical supply (voltage and phase), the type and amount of heat required (gas, heat pump/hybrid or electric), curb size and supply/return orientation, controls, and site conditions such as gas service and crane access. For a replacement, the existing unit’s model and serial number is the fastest starting point. Our equipment team will review your information and recommend suitable options before you order.
Can you help replace an existing rooftop unit?
Yes. Send us the existing unit’s manufacturer, model and serial number — a clear photo of the nameplate is ideal — along with photos of the unit and roof curb. We’ll identify suitable replacement options and point out anything that needs attention, such as curb dimensions or electrical and gas connections.
Do you provide pricing for tender projects?
Yes. Send the drawings, equipment schedule or mechanical specification along with your bid closing date, and we’ll prepare equipment pricing and technical information for the rooftop units on your project.
Can you confirm equipment availability and lead time?
Yes. Availability and lead times change with manufacturer production and inventory, so we confirm both when we prepare your quotation. The stock status shown online is a guide only.
Do you supply rooftop units outside Ontario?
Yes. We are based in the Greater Toronto Area and ship across Canada. Freight and delivery are quoted based on your project location. Installation services are offered in the GTA and surrounding Ontario regions.
What information is required to prepare a quotation?
At minimum: your contact details, project location, the number of units, and the required capacity or model. Voltage and phase, heating type and your required delivery date help us quote accurately. If you have drawings, an equipment schedule, specifications or nameplate photos, upload them with your request.
Can you identify a suitable replacement from an existing model number?
In most cases, yes. A rooftop unit’s model number usually identifies its nominal capacity, heating type and electrical configuration. We use it, together with the serial number and nameplate data, to identify current units that match as closely as possible and to let you know about any differences in dimensions or connections.
