Merit Series – Affordable and Reliable Performance

The Merit ML17XP1 is Lennox’s entry-level central heat pump, a good fit for homeowners looking for reliable performance and improved efficiency at a more accessible price point. It is aimed at replacing older air conditioners or heat pumps with a modern, ENERGY STAR-certified unit in typical Canadian homes.

Its single-stage compressor delivers consistent operation, and outdoor noise levels generally fall in the mid-70 dB range depending on size and installation. This model is often installed in detached homes and townhouses across Ontario and Western Canada as a cost-effective upgrade.

• Energy efficiency: Up to about 18.6 SEER / 10.6 HSPF (equivalent to roughly 17 SEER2 / 8.5 HSPF2).

• Cold weather performance: Suitable mainly for mild to moderate winter conditions; often paired with a furnace or backup heat in colder regions.

• Noise level: Typically falls in the mid-70 dB range.

• Warranty: Typically 10-year parts limited warranty when properly registered (labour varies by contractor).

• Estimated installed price (RoC): Around $6,500 to $9,500, depending on capacity, region and installation complexity.

Elite Series – Reliable, High-End Efficiency

The Elite XP20 offers a higher level of comfort and efficiency, thanks to a variable-capacity Inverter compressor that adjusts output to match the home’s heating and cooling needs. This helps reduce energy consumption and temperature swings, which is particularly appreciated in climates with hot summers and cool shoulder seasons like southern Ontario and coastal B.C.

The XP20 is designed as a cold-climate-capable unit when paired with an appropriate indoor system, though in very cold regions it is usually combined with a high-efficiency furnace in a dual-fuel setup.

• Energy efficiency: Up to 20 SEER / 10 HSPF.

• Cold weather performance: High efficiency in cool to cold weather; commonly used with backup or dual-fuel heating in areas that see extended deep freezes.

• Noise level: Outdoor sound levels generally in the low-to-mid 60 dB range, depending on size.

• Warranty: Typically 10-year limited warranty on compressor and parts with registration (labour coverage depends on dealer).

• Estimated installed price (RoC): Often in the $8,000 to $12,000 range, varying by tonnage, ductwork, and local labour rates.

Dave Lennox Signature – Premium Comfort and Technology

The SL25XPV is part of the Dave Lennox Signature Collection and is one of the most efficient and quietest air-source heat pumps available on the Canadian market. It features a variable-capacity Inverter compressor, advanced TruHeat performance for better heating output in colder outdoor temperatures, and smart control compatibility via Lennox communicating thermostats.

With ratings up to 24 SEER and 11.8 HSPF (23 SEER2 and 10.3 HSPF2), the SL25XPV qualifies for many utility and government incentives across Canada when installed in a compliant configuration. It is particularly attractive for homeowners looking to significantly reduce emissions and operating costs while maintaining comfort through most Canadian winters.

• Energy efficiency: Up to 24 SEER / 11.8 HSPF (23 SEER2 / 10.3 HSPF2).

• Cold weather performance: Designed as a cold-climate heat pump, with enhanced heating capacity at lower outdoor temperatures when properly matched and controlled.

• Noise level: Outdoor sound levels as low as the mid-50 dB range, depending on size and installation.

• Warranty: Commonly 10-year limited parts and compressor warranty with registration; some dealers offer extended labour coverage.

FAQ

Which Lennox heat pump is best for cold Canadian climates?

For colder regions such as the Prairies or northern Ontario, the SL25XPV is a strong option thanks to its cold-climate design and very high efficiency; many households also opt for dual-fuel systems using models like the XP20 paired with a gas furnace.

Are Lennox heat pumps eligible for rebates across Canada?

Yes. ENERGY STAR-certified models like the XP20 and SL25XPV can qualify for various utility, provincial, and federal incentives, though many homeowners now rely on newer provincial and utility programs as national programs evolve over time.

Do prices vary much between provinces?

Installed prices can be higher in regions with increased labour or travel costs, such as remote communities or some parts of Western and Atlantic Canada; urban areas with more contractors may show more competitive pricing.

How do Lennox heat pumps provide both heating and cooling?

Lennox heat pumps work by moving heat instead of making it. When heating, they take heat from the outside air—even when it’s cold—and bring it inside to warm your home. When cooling, they do the opposite: they take heat from inside your home and send it outside to keep you cool. They use a special liquid called refrigerant and parts like a compressor and valves to do this, making Lennox heat pumps an energy-efficient choice for comfort all year round.

How can I find a Lennox dealer and arrange professional installation for a heat pump?

If you want to find an authorized Lennox dealer and set up a professional installation or consultation, just head over to the official Lennox website and use their dealer locator tool. Many dealers offer free consultations and will walk you through the installation process, making sure your heat pump is the right fit for your home and installed correctly. You can also connect with dealer services through certain retailers like Costco, which might provide extra consultation or warranty perks. Remember to check that your installer is certified—this helps protect your warranty and ensures your system works at its best.
