Electric

Furnaces

Electric furnaces are great for homes across Markham that do not have access to natural gas lines. These furnaces are simple to install, run quietly, and deliver consistent, uniform warmth throughout the entirety of your interior. Simply set your temperature and unwind in warmth.

High-Efficiency

Gas Furnaces

High-efficiency ENERGY STAR-certified gas furnaces provide substantial upgrades in comfort and energy savings, making them ideal to use in big and small homes that demand reliable heating while minimizing energy costs.

Hybrid-Systems

Furnace + Heat Pump

A hybrid system combines the energy efficiency of a heat pump with the power of a gas-powered furnace. In frigid conditions, the gas heating system will switch on to provide consistent, durable warmth throughout your home. In mild weather, the system will switch over to your heat pump to keep your energy costs as low as possible.

Hot Water

Boilers

For heritage homes in Markham with radiant heating, our partnered technicians are happy to provide repair, regular maintenance, and boiler installation services in Markham as well!

WHY REPLACE YOUR HEATING SYSTEM?

Why Upgrade to an Energy-Efficient Furnace

Old furnaces or inefficient heating systems can increase your energy costs, often require more repairs over time, and are notorious for delivering uneven heating in homes. A new furnace will improve your indoor air quality, enhance your overall comfort, and ensure you never go without dependable heat, no matter how cold it gets in Markham.

Cut costs and emissions

Lower energy bills
With energy savings between 5% to 15%, high-efficiency furnaces are designed to use less energy and distribute heat more evenly. That means more money in your pocket at the end of each month.

Reduced Carbon Footprint
High-efficiency heating systems use less energy without compromising comfort, which will reduce your home's carbon footprint throughout the year. That's a win for your wallet and the local environment if you ask us!

Reliability and Pease of Mind
Avoid unexpected breakdowns and costly repairs by investing in a furnace installation in Markham that not only improves your indoor home comfort levels but also gives you peace of mind.
