Gas Furnace Buying Guide for BC

The first factor to consider is age: if your furnace is reaching the 15 to 20-year mark, it’s probably nearing the end of its life. Other symptoms may include:

• Increased energy bills, which means your furnace is no longer running efficiently.
• Uneven heating, with some rooms cooler than others or not heated at all.
• An excess of dust or soot.
• Lack of humidity in the air.
• Unusual or loud noises, such as rattling or humming, coming from your furnace.
• Frequent need of repairs.

Climate and the heating load of the home both matter. It may be tempting to choose the largest furnace available, but oversizing can reduce comfort and increase cycling. For Canadian homes, ask TEK Climate to size the equipment using a recognized residential heat-loss method such as CSA F280 rather than relying on square footage alone. The calculation considers factors such as the home’s construction, insulation, windows, doors, air leakage and local design temperatures. Once the heating load is known, you can compare appropriately sized furnace options and efficiency ratings.

Newer models generally offer higher efficiency, providing up to 97 per cent efficiency, compared to older models, at about 65 per cent. The more efficient the furnace, the less fuel – and money – wasted. Look for Energy Star® certification and a high AFUE rating. Remember, too, that energy efficiency translates to a more environmentally friendly option.

New gas furnaces are loaded with special features, thanks to technological advances over the past couple of decades. Look for: smart thermostats, ECMs (electrically commuted motors), electronic ignition, zoned heating, variable-speed blowers, dual heat exchangers and air filtration options.

The answer depends on what’s most important to you: quality, reliability, value, special features or warranty. But generally, do your research before you decide. Unbiased buyers’ guides such as Consumer Reports® should help you narrow down your choices.

Choose TEK Climate’s certified technicians for the installation of your furnace. Book a free in-home consultation with a TEK Climate advisor to assess your needs and make recommendations. Ask our team about maintenance plans and services.

Warranty terms vary by manufacturer, model and registration requirements. Before you buy, ask for the written parts and heat-exchanger warranty terms, whether registration is required, what labour coverage is included or optional, and who is responsible for warranty service.

Rebate programs change frequently, so eligibility should be confirmed before equipment is purchased or installed. In B.C., current incentives can depend on the existing heating fuel, the replacement system, the utility and the property type. Check the current FortisBC rebates and BC Hydro home renovation rebates, and confirm the program requirements that apply to your home.
