Why Lennox furnaces have earned their reputation
Lennox is a long-established North American HVAC manufacturer, and the two Lennox gas furnace models we carry are the ones that make sense for Ontario gas bills and Ontario winters.
Two-stage heating. Both the ML296V and EL297V run on a low flame most of the time and step up to full fire only during a cold snap. Longer, gentler cycles mean no more blast of hot air followed by a chilly lull.
Variable-speed blower. The motor ramps smoothly to the airflow the house needs, which is quieter, cheaper to run and better at keeping upstairs and downstairs within a degree of each other. It also makes the furnace a strong partner for a Lennox air conditioner or a heat pump in a hybrid system.
High efficiency, two ways. The Lennox ML296V at 96% AFUE is the dependable workhorse, backed by a 20-year limited warranty on the heat exchanger. The Lennox EL297V pushes to 97% AFUE and carries the ENERGY STAR label for the homeowner who wants every last point of efficiency.
Dealer-backed. As authorized Lennox installers we register your warranty, we have direct access to Lennox parts, and our TSSA-certified gas technicians are trained on the equipment.
Lennox furnace models we install
| Model | Staging and blower | Efficiency | Sizes | Installed from |
|---|---|---|---|---|
| Lennox ML296V | Two-stage, variable-speed | 96% AFUE, 20-year heat exchanger limited warranty | 45,000 / 70,000 / 90,000 / 110,000 BTU | $3,300 |
| Lennox EL297V | Two-stage, variable-speed | 97% AFUE, ENERGY STAR | 45,000 / 70,000 / 90,000 / 110,000 BTU | Quote |
Installed pricing depends on size and installation requirements such as venting, condensate drain and ductwork changes. Every quote is guaranteed.
Which Lennox furnace size fits your home
Many Ontario furnaces are oversized, which causes short cycling and cold spots. We run a heat-loss calculation before recommending a size.
| Lennox size | Typical Ontario home |
|---|---|
| 45,000 BTU | Townhouse, condo townhouse or small, well-insulated bungalow |
| 70,000 BTU | Typical bungalow, semi or smaller two-storey |
| 90,000 BTU | Average to larger two-storey |
| 110,000 BTU | Large two-storey, older or drafty home, rural home with high heat loss |
Who each Lennox furnace is right for
EL297V: maximum efficiency
You plan to stay in the house a long time and want the ENERGY STAR 97% AFUE model. Every extra point of efficiency is a smaller Enbridge bill for 20 years.
High-efficiency furnacesHybrid heat pump owners
A Lennox furnace paired with a Lennox, Midea or Kepler heat pump. The heat pump runs most of the year and the furnace covers the coldest nights at the lowest running cost.

Problems a new Lennox furnace solves
The furnace is 20 years old and the repair bills are adding up
Once a furnace is past 15 years and needs a major part, replacement usually wins on math. A Lennox ML296V from $3,300 installed resets the clock with a 20-year limited heat exchanger warranty.
Gas bills keep rising with the old 80% furnace
A 96% or 97% AFUE Lennox puts up to 17 cents more of every gas dollar into your home. On a typical Ontario gas bill that adds up fast.
The house swings hot and cold every cycle
Single-stage furnaces run flat out, then stop. Lennox two-stage heating runs on low for long, steady cycles that hold the temperature where the thermostat says.
You can hear the furnace kick on from the second floor
The variable-speed blower on the ML296V and EL297V ramps up gently rather than slamming to full speed, and runs at lower speeds most of the time.
You're adding a heat pump and want a furnace that works with it
A two-stage, variable-speed Lennox furnace is the right partner for a hybrid system. We set the changeover temperature so the heat pump runs when it's cheaper and the furnace when it's colder.

Frequently asked questions
How much does a Lennox furnace cost installed in Ontario?
A Lennox furnace installed by EHI starts at $3,300 for the ML296V, with the EL297V and larger sizes quoted based on BTU, venting and ductwork. Lennox furnace prices depend on size and installation requirements, and every quote is guaranteed before work begins.
What is the difference between the Lennox ML296V and EL297V?
Both are two-stage, variable-speed Lennox furnaces in 45,000 to 110,000 BTU sizes; the ML296V is 96% AFUE with a 20-year limited heat exchanger warranty, while the EL297V is 97% AFUE and ENERGY STAR certified. The ML296V is the value pick and the EL297V is for homeowners who want the highest efficiency Lennox two stage furnace we carry.
Do I need to register my Lennox furnace warranty?
Yes, Lennox warranty coverage depends on registration, and we complete it for you as part of the installation so your coverage is on file from day one. Extended coverage of up to 12 years parts and labour is available on select systems; see our warranty page for conditions.
Can you get Lennox parts quickly in Ontario?
Yes. As an authorized Lennox dealer we have direct access to Lennox parts and technical support, so most Lennox furnace repairs are completed the same day or the next, and we keep common parts like ignitors and flame sensors on the truck.
Is a Lennox two-stage furnace quiet?
Yes. The ML296V and EL297V use a variable-speed blower that ramps up gradually and runs at low speed most of the time, so you mostly hear a soft airflow rather than a furnace kicking on. Two-stage operation also means fewer start-ups per day.
What size Lennox furnace do I need?
The right Lennox furnace size comes from a heat-loss calculation, not from matching the old unit. As a guide, 45,000 BTU suits a townhouse, 70,000 BTU a typical bungalow or semi, 90,000 BTU an average two-storey, and 110,000 BTU a large or older home. Oversizing causes short cycling, so we measure first.
Can a Lennox furnace work with a heat pump?
Yes. A two-stage, variable-speed Lennox furnace is an ideal partner for a cold-climate heat pump in a hybrid system, where the heat pump handles most of the heating season and the furnace takes over on the coldest nights. See our Lennox heat pump page and hybrid systems page.
