Dual fuel systems that pair a heat pump with your gas furnace — efficient comfort through the long shoulder seasons, full furnace heat when it's −30 °C.
A heat pump moves heat instead of burning fuel to make it. In summer it works exactly like an air conditioner. In spring and fall it heats your home at a fraction of what it costs to run the furnace. In deep winter — Alberta being Alberta — the furnace takes back over.
That combination, a Lennox heat pump paired with a gas furnace and switching automatically based on outdoor temperature, is called dual fuel. It's the setup that makes sense in our climate, and it's what we install most often.
Illustration — a heat pump heats and cools, so Blaze and Nix share this one.
Your thermostat watches the outdoor temperature. Above the changeover point, the heat pump runs and the furnace sits idle. Below it, the furnace fires and the heat pump stops. The handoff is automatic, and in practice most people never notice it happening — they just see a different split on their bills.
In the Edmonton area, the shoulder seasons are long. October, much of November, March and April are exactly the conditions a heat pump handles well, and that's a large share of the heating season.
Heat pumps move several units of heat for each unit of electricity they consume, which is why they can beat gas in mild weather. As the temperature drops, that advantage shrinks, and at some point gas is cheaper — that's the changeover point. Whether the overall bill drops depends on your electricity and gas rates and how cold the winter turns out to be.
We'd rather explain the mechanism than promise a percentage. If someone guarantees you a specific saving without seeing your home or your bills, be careful.
We'll tell you if that's your situation. A straight air conditioner is sometimes the better buy, and we'd rather sell you the right thing once.
| Model | Series | Best for | Installed |
|---|---|---|---|
| ML14KP1 | Merit | Entry into dual fuel without a big jump in cost | $7,241.00 |
| EL16KP1 | Elite | Better efficiency, quieter year-round | $9,010.30 |
| SL22KLV | Signature | Variable capacity, maximum efficiency and comfort | $13,614.90 |
Prices are per unit in Canadian dollars, before GST, and include installation, removal and disposal of your old unit, the municipal permit and a thermostat. Final pricing is confirmed in a written quote after an in-home assessment.
“We reached out to JD Climate Contracting to replace our furnace with an energy efficient furnace / heat pump combo. JD helped us find an appropriately sized unit and once it arrived they had it installed in a single day. Would definitely reach out to JD Climate Contracting for work in the future.”
A heat pump handles mild and moderately cold weather efficiently and loses capacity as temperatures drop. That's why the practical setup here is dual fuel: the heat pump carries the shoulder seasons and the gas furnace takes over automatically in deep cold.
Our Lennox pricing is $7,241.00 for the Merit ML14KP1, $9,010.30 for the Elite EL16KP1 and $13,614.90 for the Signature SL22KLV, before GST and installed, with removal of the old unit, the permit and a thermostat.
In most Edmonton-area homes it works alongside the furnace rather than replacing it. You keep the furnace for deep cold and the heat pump handles the rest, including all of your summer cooling.
Alberta does not currently have a provincial heat pump rebate, and the federal Canada Greener Homes Grant closed to new applicants in February 2024. Lennox runs manufacturer promotions periodically — ask us what's actually running and we'll tell you honestly.
Yes. A heat pump cools exactly like an air conditioner in summer, so if you were already replacing cooling, it's worth pricing both.
The thermostat uses the outdoor temperature and a changeover setpoint. Below that point the furnace takes over; above it, the heat pump runs. You don't have to do anything.
The outdoor unit runs more often in shoulder seasons than an air conditioner would, but modern units are quiet, and the Elite and Signature models are quieter still because they modulate.
It shifts heating load from gas to electricity during mild weather, which usually lowers gas use. Whether total cost drops depends on your rates and how cold the winter is — we'll walk through your situation rather than promise a number.
