DIRECT AIR HEAT XTREME PRO R-454B Wall-Mounted Heat Pump | 18000 BTU -35°C

A Heat Pump Designed for Quebec's Demanding Winters

At AirGreen, we install HVAC systems in real-world, often complex conditions, across Montreal, Laval, Longueuil, the North Shore, and the South Shore. The DIRECT AIR HEAT XTREME PRO R-454B 18,000 BTU wall-mounted heat pump clearly falls into the category of equipment designed to perform where many others reach their limits.

This model stands out for its heating capacity down to -35°C, making it particularly relevant for properties exposed to extreme cold, especially on the outskirts of Montreal or in some more open areas of Montérégie.

We recently installed this model in a duplex in Saint-Hubert, where the client complained of significant performance loss with their old system at -20°C. Since the installation, comfort has remained stable all winter, without excessive reliance on electric backup.

Performance, Efficiency, and Subsidies: A Strategic Balance

Capacity and Performance in Real Conditions

The DIRECT AIR HEAT XTREME PRO 18000 BTU isn't just about impressive specs – it delivers concrete performance on the ground:

• Nominal Power: 18,000 BTU
• Power at -8°C: 16,600 BTU
• Power at -15°C: 18,000 BTU
• Heating capacity down to -35°C
• COP at -8°C: 1.923
• SEER2: 14.3
• HSPF2: 11.0

This type of performance significantly reduces energy costs, especially in homes where electric heating was previously dominant.

LogisVert Subsidy: A Concrete Advantage

This model is eligible for a provincial LogisVert subsidy of $1,992, which immediately improves the return on investment.

In several projects carried out in Laval and Brossard, this subsidy allowed clients to choose a more powerful system without exceeding their initial budget.

Modern Technology with R-454B Refrigerant

Why R-454B Changes the Game

The transition to R-454B gas represents a significant evolution in the field of HVAC in Quebec. This refrigerant:

• Reduces environmental impact compared to R-410A
• Maintains excellent energy efficiency
• Is already adopted by several major manufacturers

At AirGreen, we have started installing several systems using this gas, and we observe better performance stability, especially in prolonged heating.

HVAC Installation: Key Elements Not to Overlook

An Installation Tailored to Your Property

Even the best heat pump can underperform if the installation is not optimized. During our wall-mounted heat pump installations in Montreal and on the North Shore, we pay particular attention to:

• The length and quality of the piping
• The strategic location of the indoor unit
• The exposure of the outdoor unit (wind, snow, accumulation)
• The height of the outdoor support (ideally 10 to 12 inches minimum)

In a recent project in Laval-des-Rapides, an installation initially planned at ground level was adjusted for an elevated wall mount. Result: no accumulated ice problems during the winter.

WiFi Included: Smart Control

The system includes integrated WiFi connectivity, allowing for:

• Remote control via application
• More precise consumption management
• Adaptation to occupants' real schedules

Several clients in downtown Montreal use this function to optimize their heating based on their presence, thus reducing their energy bill.

Case Study: Triplex Installation in Montreal

We recently installed this DIRECT AIR 18,000 BTU heat pump in a triplex in the Villeray neighborhood.

Initial Situation:

• Primary electric heating
• Poor heat distribution
• High bills in winter

Proposed Solution:

• Installation of a wall unit in the main open-concept area
• Optimization of airflow with louver orientation
• Addition of an elevated outdoor support

Result:

• Significant reduction in heating costs
• Stable thermal comfort even during cold spells
• High customer satisfaction after a full winter of use

Common Mistakes to Avoid with This Type of System

Incorrect Sizing

An 18,000 BTU unit is powerful but must match the area and configuration of the space. Oversizing can lead to short cycles and premature wear.

Neglecting HVAC Maintenance

Even with a high-performance machine, regular HVAC maintenance is essential:

• Filter cleaning
• Coil inspection
• Drainage inspection

At AirGreen, we offer maintenance plans tailored to installed systems, particularly in the Longueuil and South Shore areas.

Ignoring the Outdoor Environment

A poorly positioned outdoor unit can lead to:

• Ice accumulation
• Reduced performance
• Unnecessary service calls
