Is 97% AFUE worth the upgrade?

Over a full Ontario heating season, the efficiency difference adds up — at up to 97% AFUE, almost all the gas the EL297V burns turns into heat. Most homeowners notice the comfort difference first: two-stage heat and a variable-speed blower hold a steadier temperature than a single-stage furnace cycling fully on and off.

What size EL297V do I need?

The EL297V is available from 44,000 to 110,000 BTU/h, which covers most homes in our service area. We size it to your home's heat loss — insulation, windows, ductwork, square footage — with an in-home assessment rather than just matching the furnace you're replacing.

Can this furnace pair with a heat pump?

Yes. The EL297V is dual-fuel capable, so it can run in a hybrid setup where a heat pump handles milder weather and the furnace takes over on the coldest days. If you're weighing a heat pump now or later, this keeps that option open without a second furnace swap.

What's the warranty on the EL297V?

Lennox covers the heat exchanger with a limited lifetime warranty and parts with a 5-year warranty that extends to 10 years once registered after installation — which we handle for you.

Is the EL297V eligible for a rebate?

No. Rebate programs currently available in Ontario apply to heat pumps and heat-pump water heaters, not standard gas furnaces, so the EL297V isn't rebate-eligible on its own.

Lennox EL297V

Name: Lennox EL297V
Brand: Lennox

The Lennox EL297V is Lennox's Elite Series two-stage furnace with a variable-speed blower, rated up to 97% AFUE. In practice, that combination means the furnace runs on its lower stage most of the time and ramps airflow up and down gradually — steadier temperatures and less noise than a single-stage unit cycling on and off. Imperial Heating sizes and installs it for homes throughout York Region, Durham and the wider GTA.
