Wall-Mounted Heat Pump Comfortmaker vs Senville: The Battle for Best Energy Efficiency

Two Brands, Two Philosophies: How to Choose the Best Wall-Mounted Heat Pump for Comfort and Energy Savings?

At AirGreen, we guide each of our clients in Montréal, Laval, Longueuil, the North Shore and the South Shore in choosing the best possible HVAC solution. When it comes to comparing two popular brands like Comfortmaker and Senville, it’s essential to go beyond simple spec sheets and analyze in depth their energy efficiency, reliability, winter performance, and real-life feedback from our own installations.

In this article, we’ll share a detailed and concrete analysis, based both on technical specs and our real experience with installations carried out in various residential and commercial neighborhoods throughout the Greater Montréal area.

Understanding the Criteria Behind True Energy Efficiency

Before we compare the two brands, let’s lay out the foundation. A high-performing heat pump in terms of energy efficiency is based on several key factors:

• Seasonal Energy Efficiency Ratio (SEER / HSPF): the higher these values, the more efficient the system is.

• Ability to heat at low outdoor temperatures (often down to -25°C or -30°C for cold climate models).

• Annual power consumption vs delivered heating capacity.

• Compressor technology (inverter, two-stage, etc.).

• Eligibility for rebate programs such as the Hydro-Québec LogisVert Program.

Overview of the Two Brands: Comfortmaker and Senville

Comfortmaker: Quiet and Consistent Efficiency

Comfortmaker wall-mounted heat pumps, while less known by the general public, are robust machines built to last, using technology derived from industry giants. The flagship model we often install — especially in single-family homes in Laval and duplexes in Montréal — offers:

• SEER of 22 and HSPF of 11.5

• Effective heating capacity down to -30°C

• High-efficiency inverter compressor

• Ultra-quiet operation (around 22 dB indoors)

• Eligible for rebates ranging from $1,500 to $2,500

These heat pumps are ideal for clients looking for an excellent quality/price ratio, long-term durability, and solid technical support. We installed an 18,000 BTU Comfortmaker unit in a home in Sainte-Thérèse (North Shore), where the client reported a 38% drop in their Hydro bill after just one season.

Senville: Budget-Friendly Versatility

The brand Senville, particularly the Leto Series, is popular among cost-conscious clients. We’ve completed many Senville installations across the South Shore, including Boucherville and Saint-Hubert, mainly in condos and rental properties.

Key features:

• SEER of 19 and HSPF of 10.5

• Effective heating down to -22°C

• Simple installation, ideal for fast projects

• Very competitive pricing

• Eligible for some rebates (depending on model)

However, it does show limitations during extreme cold. In one case in Longueuil, a client contacted us after noticing that his 12,000 BTU Senville heat pump struggled to maintain indoor temperature during a deep freeze (-27°C). We ended up adding a backup heat source to ensure comfort.

Head-to-Head Comparison: Comfortmaker vs Senville

Field Experience: What We’ve Seen First-Hand

At AirGreen, we’ve installed over 200 Comfortmaker and Senville units in the past two years across Montréal, Laval and the South Shore. Here are some real-life takeaways:

• Comfortmaker offers outstanding consistency during extreme cold, making it a strategic choice for wind-exposed areas like some properties in Saint-Jérôme or Pierrefonds.

• Senville is a smart budget option for well-insulated spaces with moderate heating needs, such as small condos in Longueuil or duplexes in Laval.

• For after-sales service, Comfortmaker has more readily available replacement parts, allowing us to respond faster when needed.

Our Recommendation

If you’re looking for a wall-mounted heat pump that performs, lasts, and is ready for Québec winters, Comfortmaker is a safe long-term investment — especially if you take advantage of the available rebates.

On the other hand, for tight budgets or smaller spaces, Senville can be a solid choice — provided you have good insulation and are aware of its limits during extreme cold.

We always recommend having an HVAC professional assess your real needs. At AirGreen, our team offers free home visits to give you a detailed estimate based on the size of your home, its orientation, insulation, your consumption habits, and energy goals.
