Cool comfort: natural gas furnace plus air conditioner
Losing sleep over summer heat? If you have a natural gas furnace, you can simply add an air conditioning unit to your central heating system and enjoy year-round climate control and comfort in your home. You don’t need a heat pump to keep your home cool.
Heat pump or air conditioner—what’s the difference?
A heat pump is an electrical appliance that extracts heat from one place and transfers it to another. To warm up your home, it heats air from outside and injects it into your home. To cool down your home, it moves heat from inside your home to outside.
An air conditioner works in much the same way to keep your home cool, but of course it doesn’t heat your home.
While an electric air source heat pump can heat and cool your home, there are factors you’ll need to consider:
- The climate you live in - when temperatures get colder, heat pumps need to rely on a backup heating system, which will increase your heating costs.1 There are cold climate heat pumps which work better in colder temperatures, but these are more expensive.
- In Canada, we need heating more than cooling - Because you’ll be needing heat in your home for the majority of the year, it makes sense to consider your most affordable heating option first, and then think about your cooling needs.
- Your existing heating system - If you have a natural gas furnace and you switch to a heat pump, your natural gas bill will go down, but your electricity bill will go up.1 And natural gas is about one third the cost of electricity.
Bottom line: if you have access to natural gas, it’s still the most affordable option for home heating, compared with electricity and heating oil. And if you already have a natural gas furnace, you just need to add an electric air conditioner to your central heating system to ensure year-round comfort and savings.
Natural gas furnace + air-conditioning unit = cool savings
Natural gas is about one-third the cost of electricity and heating oil. Based on current gas rates, a single family home with average energy use can expect to save up to $485 per year in energy costs1 by choosing to cool the home with a natural gas furnace/air-conditioning combination, compared with a heat pump.

1BC Hydro - Should you get a heat pump?
2These are approximate annual costs for space heating and cooling of a typical household in Victoria. A typical household is defined as a single family house approx. 2,300 square ft. with average insulation. Anticipated savings will be the difference between annual natural gas and electricity. Calculations compare a 98% efficient natural gas furnace paired with Central AC with a SEER of 15, and an electric air source heat pump with an HSPF of 8.2 and SEER of 15. Comparisons are based on FortisBC natural gas rates as of October 2020 and BC Hydro electricity rates as of April 2020. Both gas and electric prices are subject to change. These include applicable carbon tax. Savings may vary by household and do not include potential rebates and/or incentives.
