A heat pump designed for Quebec's extreme climate, with actual performance down to -35°C

At AirGreen, we install hundreds of HVAC systems every year in a wide variety of conditions in Montreal, Laval, Longueuil, on the North Shore and the South Shore. The DIRECT AIR HEAT XTREME PRO R-454B 24,000 BTU wall-mounted heat pump has quickly established itself as a serious solution for customers looking for a reliable machine that performs well in winter and is eligible for significant subsidies.

This model stands out for its ability to maintain stable heating even during periods of intense cold, with advertised performance down to -35°C, which is particularly relevant for Quebec winters.


Why this model is attracting so much attention in Greater Montreal

Impressive heating capacity at low temperatures

One of the critical points in choosing a wall-mounted heat pump in Quebec is its actual ability to heat when temperatures drop drastically. This model offers:

  • Nominal power: 24,000 BTU
  • Power at -8°C: 22,200 BTU
  • Power at -15°C: 24,200 BTU

In our recent installations in Laval and Boucherville, we have observed that this machine maintains consistent comfort even in poorly insulated homes or those with large glazed areas — typical cases in several South Shore properties.

Recognized energy efficiency

This model is certified:

  • ENERGY STAR®
  • ENERGY STAR® Cold Climate

With solid technical performance:

  • SEER2: 30
  • HSPF2: 13.5
  • COP at -8°C: 3.43

This means a significant reduction in heating and cooling costs, especially in regions like Montreal and Longueuil, where seasonal temperature variations are significant.


Modern technology with R-454B refrigerant

Why R-454B is a strategic advantage

The transition to R-454B gas is an important evolution in the HVAC field. This refrigerant offers:

  • Reduced environmental impact compared to R-410A
  • Better overall energy efficiency
  • Compatibility with future standards

At AirGreen, we already prioritize systems using this type of refrigerant in our recommendations, as they ensure better long-term durability.


Concrete example of an installation carried out by AirGreen

Project in Longueuil: replacement of an inefficient central system

A client in Longueuil had an old, energy-intensive central system that no longer met their winter heating needs. After analysis, we recommended this DIRECT AIR HEAT XTREME PRO 24,000 BTU heat pump.

Challenges encountered:

  • Limited space for the outdoor unit
  • Old, non-optimized electrical installation
  • Need for high heating performance

AirGreen Solution:

  • Installation on a raised stand to avoid snow accumulation
  • Electrical circuit adjustment (220V compliant)
  • Optimization of indoor positioning for uniform diffusion

Result:

  • Immediate reduction in energy costs
  • Stable comfort even during periods of intense cold
  • Client eligible for a LogisVert subsidy of $2520

Available subsidies and real savings

This heat pump is eligible for a provincial LogisVert subsidy of up to $2520 (according to the latest updates).

In several cases in Montreal and Laval, our clients recover a significant portion of their initial investment, which makes this type of system very competitive compared to classic electric alternatives.


HVAC Installation: What You Absolutely Need to Know

Common mistakes to avoid

After hundreds of installations, here are the mistakes we often see:

  • Choosing a heat pump based solely on price
  • Neglecting the quality of installation
  • Installing an outdoor unit too close to the ground
  • Ignoring specific electrical requirements

Our approach at AirGreen

Every HVAC installation project is handled with precision:

  • Complete analysis of thermal needs
  • Verification of AHRI combinations (number: 216571375)
  • Installation in compliance with RBQ standards
  • Complete tests (vacuum, pressure, operation)

Comfort and smart control

This unit includes:

  • Integrated WiFi
  • Advanced air direction control
  • Optimized silent operation

In several residences in Montreal, we have observed that customers particularly appreciate remote control, especially for adjusting the temperature before their arrival.


HVAC maintenance: extending the lifespan of your system

A high-performance wall-mounted heat pump requires regular maintenance.

AirGreen recommendations:

  • Annual complete cleaning
  • Pressure and performance check
  • Inspection of the outdoor unit (snow, ice, debris)

We also offer tailored HVAC maintenance plans to ensure consistent performance and avoid costly breakdowns.


Warranty and peace of mind

  • Compressor: 10 years
  • Parts: 10 years
  • Labor: 0 year (additional option available)

At AirGreen, we offer extended warranty options to secure your investment, particularly for residential and multi-unit installations.
