Upgrade to a 96–98% AFUE gas furnace — extract up to 98¢ of heat from every dollar of gas, reduce your FortisBC bills, and qualify for CleanBC rebates. Free in-home sizing and assessment.
Standard furnaces run at 60–80% AFUE — 20–40¢ of every gas dollar escapes up the flue. A 96–98% AFUE furnace captures almost all of that heat. Here's what the upgrade delivers.
The defining technology behind 96%+ ratings. A second heat exchanger captures heat from exhaust gases that a standard furnace vents outside — converting flue loss into usable warmth.
Adjusts output from ~40% to 100% capacity based on demand rather than cycling on and off at full blast — more consistent temperatures and significantly less gas burned per heating cycle.
Moves air slowly and steadily at low demand rather than blasting at full speed. Quieter, better humidity control, and lower electricity use alongside your gas savings.
Draws outdoor air directly for combustion rather than pulling conditioned air from your living space — eliminating backdraft risk, improving efficiency, and meeting BC safety codes.
Replacing an 80% AFUE furnace with a 96% unit typically saves $250–$500/year on a Metro Vancouver home at current FortisBC rates — the upgrade often pays back within 5–7 years.
An oversized high-efficiency furnace is still inefficient. Every Climax Energy install starts with a Manual J heat loss calculation to size the equipment exactly right for your home.
Both ratings deliver significant savings over a standard furnace. The right choice depends on your home's size, insulation level, and whether a dual-fuel system makes sense for your situation.
High-efficiency gas furnaces with modulating burners and variable-speed blowers for consistent, quiet comfort and lower gas bills.
Zero-combustion electric furnaces ideal for homes without gas service. Simple, safe, and compatible with BC's clean energy grid.
A heat pump handles efficient heating most of the year, with a gas furnace as backup for the coldest days — maximum comfort, minimum cost.
High-efficiency boiler systems for hydronic radiant heating — even, draft-free warmth through in-floor or baseboard radiators.
Switching from an old furnace to a high-efficiency system or heat pump can qualify you for significant CleanBC incentives. We handle the paperwork so you keep the savings.
We don't just swap boxes — we engineer your heating system for peak performance, efficiency and longevity, then stand behind our work with an industry-leading warranty.
An aging furnace working at 60–75% AFUE burns significantly more gas than a modern 96–98% unit to produce the same heat. These are the signs it's time to upgrade.
Most furnaces have a 15–20 year lifespan. Beyond that, efficiency drops and breakdowns become more frequent and costly.
If your gas or electric bills keep climbing despite normal usage, your furnace is likely losing efficiency and working harder than it should.
Hot and cold spots throughout your home often indicate a furnace that can no longer distribute heat properly, or one that was never sized correctly.
If you've called for repairs two or more times in the past two years, replacement usually costs less than continued fixes on an aging unit.
