Generallux-Manuflow Wall-Mounted Heat Pump: The Small Québec Brand Taking on the Global Giants

A Local Installation, Global Performance: The Surprising Rise of the Generallux-Manuflow Wall-Mounted Heat Pump

At AirGreen, we’re used to working with well-known international brands like Fujitsu, Gree, Mitsubishi, or Sharp. But sometimes, a local product enters the scene and shifts the landscape. That’s exactly what’s happening with the Generallux-Manuflow wall-mounted heat pump, a Québec-based brand that’s quietly making waves by offering innovative technology, impressive reliability, and a price-to-performance ratio that’s hard to beat.

We recently installed a Generallux-Manuflow 12,000 BTU unit in Longueuil, on the South Shore of Montréal, for a residential customer looking for a solution that was affordable, high-performing, and backed by local support. This installation gave us a chance to truly test this heat pump's capabilities and assess its real-world value.

A 100% Québec-Based Brand: Local Vision, Design, and After-Sales Service

What makes Generallux-Manuflow stand out is its understanding of Québec’s specific climate challenges and energy efficiency needs. Designed and distributed by a Québec company, this wall-mounted heat pump is built to tackle our brutal winters while keeping things cool and efficient in the summer months.

One of the biggest advantages our technicians noted during this installation was the responsiveness of the after-sales service. If there’s ever an issue, technical support is quick, and parts are stocked locally—which drastically shortens repair and maintenance delays. In the residential HVAC world, that’s a major win.

Technical Details of the Generallux-Manuflow Heat Pump Installed in Longueuil

The model selected for this job was a 12,000 BTU wall-mounted unit, ideal for spaces between 400 and 600 sq. ft. Here are the main specs:

  • Heating Capacity: Down to -25°C

  • SEER: 20.5 (very high for this category)

  • HSPF (seasonal heating efficiency): 11.2

  • Refrigerant: R-32, more eco-friendly and efficient than R-410A

  • Built-in Wi-Fi: Allows remote control via mobile app

  • Certifications: Energy Star, eligible for LogisVert and Chauffez Vert rebates

Thanks to its variable-speed inverter compressor, this unit offers smart power modulation based on real-time demand. That means thermal comfort is maximized while energy consumption stays low.

A Custom Installation with Technical Constraints in Longueuil

Our client, the owner of a 1980s bungalow in Longueuil, wanted a discreet wall-mounted installation that wouldn’t affect the visual appeal of the front of the home. The challenge was to run the refrigerant lines to the rear of the house, bypassing a closed-in porch—without drilling into any visible exterior walls.

Our installers chose to route the lines through the crawl space, which allowed us to keep the drain and refrigerant pipes protected from freezing, while also ensuring a flawless exterior appearance. The outdoor unit was mounted on a precast concrete slab with anti-vibration pads and a winter weather cover.

Why This Wall-Mounted Heat Pump Is Gaining Ground with Québec Homeowners

As we carry out more installations, we’re seeing a noticeable rise in demand for Québec-based wall-mounted heat pumps, and Generallux-Manuflow is leading the way. The brand directly addresses the top three concerns we hear from clients:

  1. Affordable Purchase Price: Up to 30% cheaper than equivalent Japanese models.

  2. Climate-Ready Performance: Consistent heating, even in deep freeze conditions.

  3. Easy Access to Service and Parts: Crucial for long-term equipment performance.

This brand also qualifies for energy transition rebates, such as Hydro-Québec’s LogisVert program, allowing clients to receive up to $1,445 to $1,704 depending on the model and BTU size.

Our Professional Opinion: A Reliable Brand, but Installation Matters

While the product shows real promise, proper installation is essential. At AirGreen, we’ve noticed that Generallux-Manuflow units require precise airflow calibration to prevent high-speed whistling noises. That’s why our teams fine-tune the fan speed settings during commissioning, ensuring quiet, optimal performance.

We also recommend installing a high-quality wall bracket for outdoor units. This extends compressor life and reduces vibrations that could affect performance over time.

Practical Tips for Future Buyers of Québec-Made Wall-Mounted Heat Pumps

  • Always check for rebate eligibility: A cheaper unit might not qualify for provincial programs.

  • Get it installed by a certified professional: A good product poorly installed won't deliver results.

  • Consider local after-sales support: It’s just as important as the equipment’s specs.

  • Compare SEER and HSPF ratings: These numbers reveal real-world efficiency.

Successful Installations Across Montréal, Laval, and the North Shore

In addition to the Longueuil installation, we’ve recently installed other Generallux-Manuflow units in:

  • Ahuntsic (Montréal): In a duplex, used in a bi-zone setup

  • Laval-des-Rapides: Replacing an old wall-mounted AC with a 18,000 BTU heat pump

  • Boisbriand (North Shore): Installed on a cottage with complex drainage requirements

Each time, we tailored the installation method to the home’s structure and the residents' lifestyle—always following the strictest standards in residential HVAC.

Final Thoughts: A Brand to Watch Closely

At AirGreen, we believe the Generallux-Manuflow wall-mounted heat pump has earned its place alongside the big names. It’s a smart choice for anyone who wants to support a local company while enjoying reliable, high-performance technology that’s designed for Québec’s climate.

With our expertise in wall-mounted heat pump installations across Montréal, Laval, Longueuil, the North Shore, and the South Shore, we’re proud to offer our customers efficient, durable solutions backed by unbeatable service.
