The benefits of a rooftop unit
Installed mainly on building roofs, rooftop units are versatile appliances combining three functions: heating, air conditioning and ventilation in commercial spaces. These units are frequently chosen because of the benefits they offer, namely decentralization of the ventilation system and central area heating in open-plan spaces.
Opt for a hybrid rooftop unit
Choosing a hybrid rooftop unit means investing in an energy-efficient solution that combines the best of electricity and natural gas.
With a hybrid system, you optimize energy consumption while ensuring consistent performance, even during peak winter periods. The unit automatically adjusts the energy source according to conditions: electricity powers a heat pump that provides space heating and cooling, while a natural gas burner takes over from the heat pump in very cold weather when the thermometer dips to -12°C or -15°C, depending on the region.
In choosing a hybrid rooftop unit, you may qualify for our dual energy offer, which includes:
Grants for the purchase and installation1 of your new equipment to reduce upfront costs
A preferential electricity rate3 that can generate significant annual savings on your energy bill.

1. Certain conditions apply.
Grant amounts vary depending on the power of the appliances installed and the work done to install them.
Grant amounts cannot exceed 80% of the premium cost2 associated with the purchase and installation of the appliances.
Costs for electrical work may be added to the cost of purchasing and installing the equipment.
To take advantage of the grants, you must sign a contract with your Énergir sales representative or certified natural gas partner prior to installation.
The grant amounts and program terms and conditions are subject to change without notice.
2. The premium cost for a project is the difference between the estimated cost of a project (the cost of purchasing and installing a dual-energy system) and the estimated baseline cost (the cost of purchasing and installing a natural gas appliance).
3. By switching to dual energy, business customers benefit from the dual-energy rate of their electricity provider. The costs and potential savings were calculated based on Hydro-Québec’s Small- and Medium-Power Dual-Energy Rate. Hydro-Québec's dual-energy rate is in effect during the heating season, from October 1 to April 30. Outside of this period, from May 1 to September 30, electricity prices for dual energy are the same as the base rates (G, M, or G9).
