LOCALLY OWNED & OPERATED
Dual-Fuel Heat Pump & Furnace Specialists
Reduce fossil-fuel use while keeping the reliability of your furnace.
Modern HVAC designs and installs heat-pump systems that work alongside propane and natural-gas furnaces for efficient heating, central cooling and dependable backup heat.

ONE INTEGRATED SYSTEM
Heat Pump Efficiency. Furnace Reliability.
The Hisense heat pump provides efficient electric heating and summer air conditioning. Inside the home, its indoor coil sits above the furnace. The furnace blower moves air across that coil and through the existing duct system.
When the selected changeover conditions are reached, the furnace automatically becomes the heat source.



LESS RELIANCE ON PROPANE
This Is Where Dual Fuel Gets Especially Interesting.
Instead of relying on propane for the entire heating season, a heat pump can handle a significant portion of your home’s heating whenever conditions and operating costs make sense. Your propane furnace remains installed and ready when needed.
Shift more of the heating load to electricity.
The same heat pump provides winter heating and summer cooling.
Properly configured controls automatically transition between heating sources.
Reliable propane heating remains available when needed.
ONTARIO HEAT PUMP REBATES
Modern HVAC participates in Ontario’s Home Renovation Savings Program, helping eligible homeowners take advantage of available rebates when installing qualifying heat-pump systems.
For qualifying purchased cold-climate air-source heat pumps in homes currently heated with electricity, oil, propane or wood.
Eligible cold-climate air-source heat pumps may qualify for rebates up to $7,500, depending on system size, equipment eligibility and program requirements. Eligible Enbridge Gas customers heating with natural gas may qualify for up to $2,000.
Whether you currently heat with propane, natural gas, oil or electricity, we can help you determine whether your planned system may qualify and guide you through the HVAC portion of the upgrade.
Eligibility, qualifying equipment, rebate amounts and program requirements are determined by the Home Renovation Savings Program and may change. Final eligibility is subject to current program rules.
FLEXIBLE FINANCING AVAILABLE
Modern HVAC offers financing options through Financeit for eligible heating, cooling and hot-water projects.
Financing can help spread the cost of a new system over manageable payments while allowing homeowners to complete the upgrade their home needs today.

Before installing another A/C, consider a heat pump.
A traditional air conditioner provides cooling only. A heat pump provides central cooling while also giving your home another source of heat.
For propane-heated homes in particular, that added heating capability can make the upgrade considerably more valuable.

ANOTHER WAY TO HEAT
Heat pumps also work alongside natural-gas furnaces. Enjoy inverter heating, central cooling, reduced natural-gas consumption and two available heating sources with automatic operation.
Because natural gas is generally a lower-cost heating fuel, financial savings may build more slowly than with propane. We evaluate your equipment, energy costs and comfort goals to help you decide whether the combination fits your home.
Discuss natural-gas dual fuelExplore Your Options Before Installing Another Oil System.
Modern HVAC helps homeowners convert away from oil. We look at your home and existing system before recommending a replacement.


When equipment sits in the middle of a building or another difficult location, venting a new propane or natural-gas furnace outdoors may be impractical.
An all-electric air handler paired with a heat pump can be a strong oil-conversion option: heat-pump heating, central cooling and electric backup where required, without new fossil-fuel appliance venting.
We assess electrical capacity, ductwork and heat loss to determine whether this practical solution is the best fit.

BETTER COMFORT IS MORE THAN TEMPERATURE
Modern HVAC offers whole-home solutions to help improve comfort, humidity control, filtration and fresh-air ventilation.
Whole-home humidifiers can help maintain more comfortable indoor humidity during dry Ontario winters.
Whole-home dehumidification can help control excess moisture and improve comfort during humid weather.
HRVs bring fresh outdoor air into the home while recovering heat from outgoing exhaust air, helping improve ventilation without wasting as much conditioned energy.
Higher-capacity whole-home filtration options can provide better filtration than basic furnace filters.
THE MODERN HVAC APPROACH
We look at the entire system — not simply the box being replaced.
Match equipment to your home’s heating and cooling needs.
Check how air moves through the complete system.
Consider existing distribution and practical improvements.
Make everyday operation straightforward.
Select changeover settings for the actual equipment and energy costs.
Check operation and explain how to use the finished system.

A dual-fuel system combines an electric heat pump with a propane or natural-gas furnace. Controls select the appropriate heat source, and the heat pump also provides summer cooling.
Yes, with compatible equipment, suitable ductwork and properly configured controls. The furnace remains available when the system calls for furnace heat. Learn about our heat pump and propane furnace systems.
Yes. A compatible natural-gas furnace can work with a heat pump in a dual-fuel system. The right setup depends on heating demand, equipment performance, energy prices and the homeowner’s goals.
It is worth comparing, particularly when replacing an air conditioner or planning a heating upgrade. A heat pump can reduce propane use, but operating costs depend on your home, energy prices and system design. Savings are not guaranteed.
Yes. A correctly selected heat pump can provide cooling in summer and heating when needed. Existing indoor equipment, electrical capacity and airflow should be assessed before choosing a replacement.
Options include a propane or natural-gas furnace where suitable, a heat pump paired with one of those furnaces, or an all-electric heat pump and air handler. Explore oil furnace replacement options based on your home’s fuel access and heating needs.
Yes. Modern HVAC designs heat-pump systems with a backup heat source. In a dual-fuel system, the propane or natural-gas furnace provides backup heat. In an all-electric system, electric resistance heaters in the air handler provide backup heat when the heat pump cannot meet the home’s heating needs on its own.
Qualifying installations may be eligible through the Home Renovation Savings Program. Amounts and eligibility depend on the existing heating source, equipment and current rules. Check the official program requirements before proceeding.
