When Does Your Multi-Zone Heat Pump Become Cost-Effective? A Precise Example from a Home in Laval

A Strategic HVAC Investment: Cost-Benefit Analysis of a Multi-Zone Heat Pump Installed in Laval

Installing a multi-zone heat pump in a Laval home isn’t just about comfort—it’s a long-term energy and financial investment. At AirGreen, we recently completed a full installation in a single-family home located in the Vimont neighbourhood of Laval. This project provides a clear, real-world example of when a properly designed multi-zone system becomes profitable.

Thanks to a detailed analysis of energy usage, the home’s structure, the occupants’ habits, and applicable grants, we were able to determine the precise moment this investment started paying off—and the results are crystal clear.

Home Profile: A Typical Laval Scenario

This project involved a 2,100 sq. ft. house spread over two floors with a finished basement. The property had an old electric baseboard heating system in each room and an outdated single-zone heat pump that only served the living room.

The client’s objective: upgrade the home's thermal comfort, lower their electric bills, and increase their property’s resale value.

Equipment Details

To meet the client’s needs, we recommended and installed a Gree Free Match multi-zone heat pump with the following specifications:

• Outdoor unit: Gree Free Match 36,000 BTU (R-410A)

• Indoor units:

  • Living room: 12,000 BTU

  • Master bedroom: 9,000 BTU

  • Basement: 9,000 BTU

  • Second-floor office: 6,000 BTU

• Energy efficiency: SEER 20 / HSPF 10

• Warranty: 10 years parts and compressor

• LogisVert grant: $2,780 available via Hydro-Québec

The installation was completed over two days without any major disruption to the family’s routine. Existing wiring was partially reused, which helped reduce overall project costs.

Cost-Benefit Analysis: When Does the ROI Become Real?

One of the most common questions we hear from clients is: “How long before this system pays for itself?”

Here’s a simplified but realistic breakdown based on this specific installation in Laval:

Total project cost:

• Equipment + installation: $10,400

• LogisVert grant: - $2,780

• Net cost: $7,620

Annual savings:

• Old Hydro bills: ~ $3,200/year

• Estimated new bills: ~ $1,800/year

• Average annual savings: $1,400

Break-even point:

• $7,620 ÷ $1,400/year = 5.4 years

Bottom line: the heat pump becomes profitable after approximately 5 years and 5 months. And that’s not even counting the increase in property value and the year-round comfort improvement.

Project Specifics in Laval: Challenges and Solutions

As is often the case with homes built in the 1980s, we encountered a few layout challenges:

• Limited space for the outdoor compressor: We installed an elevated anti-vibration slab between two basement windows, while respecting all clearance codes.

• Finished ceilings in the basement: For the basement indoor unit, we opted for a ceiling cassette instead of a wall-mounted unit to preserve aesthetics.

• Visible electrical conduits: We painted the covers to match the brick siding, ensuring a visually seamless integration.

Why Choose a Multi-Zone Heat Pump in Laval?

The Laval region, with its harsh winters and increasingly hot summers, is an ideal setting for multi-zone heat pumps. Here’s why:

• Customized comfort: Independent temperature control in every room.

• Reduced heating costs: Up to 50% savings annually.

• Centralized air conditioning: Quieter and more uniform than portable AC units.

• Generous grants: Thanks to provincial and federal programs.

Common Mistakes to Avoid with Multi-Zone Installations

At AirGreen, we’ve had to fix several poorly planned installations over the years. Here are the most common pitfalls:

1. Choosing an underpowered outdoor unit: This leads to underperformance during cold spells.

2. Excessively long refrigerant lines: Can decrease system efficiency.

3. Skipping a proper thermal assessment: Every home is unique—accurate sizing is crucial.

4. Missing out on eligible grants: A mistake that can cost homeowners thousands.

We account for all these variables thanks to our free in-home HVAC assessment and tailored planning.
