Installation of a Zephyr 25 R454B Wall-Mounted Heat Pump in Montréal-Est

A highly efficient CVAC solution for lasting comfort, even in extreme cold

At AirGreen, we recently had the privilege of completing the installation of a Zephyr 25 R454B wall-mounted heat pump in a home located in Montréal-Est. This project is part of our commitment to providing high-performance CVAC solutions, designed to perfectly adapt to the climatic realities of Greater Montreal, while ensuring maximum comfort and optimized energy consumption.

Project Context and Residential Setup

This residential property featured a typical medium-sized family home, with an open-plan layout on the ground floor and interconnected bedrooms. The client was seeking a reliable heating and cooling solution, energy-efficient, and sufficiently discreet to blend seamlessly with the interior environment.

The choice naturally leaned toward the Zephyr 25 R454B wall-mounted heat pump, a model recognized for its performance even in extreme winter conditions, its compact size, and its quiet operation.

Why the Zephyr 25 R454B?

This high-efficiency wall-mounted heat pump is powered by a rotary inverter compressor. It is specially designed for the cold climate of Quebec, with a heating capacity down to -30°C and a cooling capacity down to -15°C. Here are some key features of this unit:

• Up to 25 SEER2 and 11 HSPF2, offering exceptional energy efficiency

• R-454B refrigerant, more environmentally friendly

• Compressor pre-heating technology and integrated chassis heating

• 4D automatic oscillation, for even air distribution

• Ultra-quiet operation: as low as 32 dB indoors

• Backlit wireless remote control with "iFeel" sensor

• 10-year warranty on parts, with labor warranty option

This model is an excellent choice for families seeking consistent thermal comfort and long-term savings, while benefiting from cutting-edge technology in a compact format.

Installation Details in Montréal-Est

Strategic Placement for Optimal Distribution

The indoor unit was installed above a central door in a hallway, a typical setup but one that requires rigorous technical precision. Thanks to our expertise, we were able to:

• Maximize airflow towards adjacent rooms such as bedrooms and the living room

• Ensure visual discretion without compromising aesthetic integrity

• Maintain a safe clearance from the ceiling and door frames

Work Completed

• Drilling of the wall and airtight sealing for refrigerant piping passage

• Installation of the outdoor compressor on an antivibration wall mount on the rear facade

• Dedicated electrical connection in compliance with safety standards

• Complete system testing (cooling, heating, defrost, silent mode, "iFeel", oscillation)

• Calibration of the remote control according to the main living zones

• Explanation of operation to the resident family

The entire installation was completed in less than one day, with no disruption to the occupants.

Performance and Results Observed

Upon initial startup, the occupants noticed:

• A rapid temperature increase, even during cold, damp conditions

• Remarkable silent operation

• Even room temperature distribution in the hallway and adjoining rooms

• Precise control thanks to the ultra-wide frequency modulation technology

This installation demonstrates how well the Zephyr 25 R454B is suited for urban residences in Montreal, where the harsh winter climate can present significant challenges.

Grants and Eligibility

Thanks to its high energy performance and ability to operate at very low temperatures, this model is eligible for several financial aid programs, including:

• Hydro-Québec's LogisVert Program (up to $1,704, depending on configuration)

• Municipal (Montréal-Est) or federal grants via the Green Homes Program

Our advisors assisted the client in preparing the documentation and submitting the grant application, a key service we offer to all our clients.

Tips for Homeowners Looking for a Wall-Mounted Heat Pump

Before selecting a heat pump, here are some crucial factors to consider:

1. Heating capacity for cold climates: opt for models tested down to -25°C and below.

2. Modern refrigerants: prioritize R-32 or R-454B, which are more eco-friendly.

3. Professional installation: only a certified installer can guarantee performance and safety.

4. Grant eligibility: an Energy Star-rated model is often required.

5. Silence and comfort: proper sizing and automatic oscillation ensure even temperature distribution.
