Let's discover together why this solution is a benchmark in Greater Montreal, Laval , Longueuil , on the South Shore and the North Shore .
Performance designed for Quebec residential comfort
The Zephyr R-454B with 36,000 BTU compressor is a dual-zone model capable of efficiently heating two separate indoor spaces with a single compressor. Here are the features that make it a must-have:
-
Heating capacity to -25°C : ideal for facing Montreal winters.
-
SEER2 of 22.0 and HSPF2 of 10.0 : exceptional energy efficiency.
-
R-454B refrigerant : a more environmentally friendly technology.
-
Inverter technology : allows continuous adjustment of power according to actual needs.
-
ENERGY STAR® – Cold Climate : Certified for optimal performance even in extreme cold.
-
Multiple inner head options : ZE09CB25I, ZE12CB25I, ZE18CB25I and ZE24CB25I, for a perfect fit for every room.
A quiet unit designed for home tranquility
In a home, comfort doesn't just come from temperature: silence is just as precious. The Zephyr understands this:
-
Exterior noise level of 59 dB(A) : a remarkably quiet performance for its power.
-
Possibility of installation with very low noise wall heads.
-
High-performance motor and optimized sound insulation.
Many of our customers, from Montreal to Boucherville , point out that they can't even hear the device once it's on—a real guarantee of comfort for nighttime or teleworking spaces.
A flexible system that grows with you
Although it comes in dual zone , the Zephyr R-454B is capable of handling up to four zones (quad zone configuration). This means that your initial investment remains scalable:
-
Starting with two pieces? No problem.
-
Want to add two zones later? The unit can support them without having to replace the compressor.
At AirGreen, we see this flexibility as a smart response to the needs of a transforming home, particularly for growing families or future renovation projects.
