Wall-mounted heat pump technologies are evolving fast, and 2025 is shaping up to be a pivotal year for innovation in residential and commercial heating and air conditioning. At AirGreen, we closely monitor industry developments to offer our clients in Montreal, Laval, Longueuil, the North Shore and the South Shore the most efficient, durable, and cost-effective HVAC systems on the market.
Here’s a complete overview of the five major trends that will shape wall-mounted heat pumps in 2025 — including practical advice, brand recommendations, real-world examples from AirGreen installations, and our expert insight tailored to the Quebec market.
1. The widespread shift to eco-friendly refrigerants (R-32 and R-454B)
Heat pump manufacturers are switching to new low-global warming potential (GWP) refrigerants to meet the stricter environmental regulations coming into effect in Quebec and across Canada in 2025.
Why it matters:
R-32 and R-454B refrigerants are far less polluting than R-410A, which is still commonly used. They also deliver better energy efficiency.
What we’re installing:
At AirGreen, we’re already prioritizing models like the Sharp ZU1, the Fujitsu KZAH (R-32), and the Bosch BOVA/IDS Premium (R-454B), helping our clients stay ahead of the regulations without sacrificing performance.
Real-world example:
In 2024, we replaced an outdated R-410A unit with a Fujitsu KZAH 18,000 BTU wall-mounted heat pump in a Saint-Lambert home on the South Shore. The result: a 30% drop in annual electricity consumption, while already complying with upcoming environmental standards.
2. The rise of variable-speed inverter multizone systems
Inverter technology is now a must, but in 2025 it will become even more powerful with improved variable-speed compressors and a boom in multizone systems.
Key advantages:
-
Greater energy savings (up to 40% compared to standard ON/OFF systems)
-
Enhanced comfort with stable temperature and quieter operation
-
Capability to control up to 5 separate zones with one outdoor unit
Our approach:
We frequently install Gree Multizone Lomo or Fujitsu Multi systems in Montreal’s duplexes and triplexes, giving each floor its own customized climate control.
3. Integration of heat pumps with smart homes
Compatibility with home automation systems is becoming essential. In 2025, most wall-mounted heat pumps will connect to Google Home, Alexa, or dedicated mobile apps.
What this means:
-
Remote control via smartphone
-
Smart scheduling based on occupancy
-
Smarter energy usage and consumption tracking
What we offer:
Models like the Gree Sapphire or Tosot Lomo+ Ultra Heat come with built-in Wi-Fi modules, and we configure them for every client. In Laval, we recently equipped a family with a Tosot Lomo+ 24,000 BTU unit integrated into their Control4 home automation system, allowing them to manage their comfort remotely while traveling.
4. Eligibility for LogisVert and RénoClimat grants: a strategic opportunity
In 2025, many wall-mounted heat pumps will still qualify for government grants, such as:
-
Up to $2,172 through Hydro-Québec’s LogisVert Program
-
Up to $5,000 via RénoClimat
-
Additional local support available in Montreal and Longueuil
Our service:
We guide our clients step by step through the grant application process. This includes checking eligibility, assisting with energy audits, and submitting the required documents.
Testimonial:
A homeowner in Terrebonne received $4,600 in grants for installing an 18,000 BTU Haxxair wall-mounted heat pump, with our full support throughout the process.
5. Boosted heating performance for cold climates
With increasingly unpredictable winters, cold-climate-ready heat pump models are becoming the norm. In 2025, several models guarantee reliable heating performance down to -30°C.
Our top-performing models:
-
Gree Extreme Ultra Heat
-
Fujitsu XLTH
-
Sharp ZU1 Inverter Cold Climate
Installation considerations:
Every installation must be adapted to the thermal profile of the building: insulation, wind exposure, room layout. This is where our HVAC expertise becomes essential.
Technical example:
In Boisbriand, on the North Shore, we installed a Gree Extreme 18,000 BTU heat pump with a reinforced compressor and antifreeze protection for the piping. The homeowner removed all electric baseboards and cut their annual energy bill by 43%.
