How to Cut Energy Consumption with a Wall-Mounted Heat Pump: Our On-Site Expertise
At AirGreen, we know that a well-chosen and properly installed HVAC system can drastically improve the comfort of a home while cutting energy bills in half. In this article, we’re sharing our best expert tips, drawn from dozens of projects completed in Montréal, Laval, Longueuil, and across the North Shore and South Shore, to help you maximize the efficiency of your wall-mounted heat pump. Through a rigorous approach, smart equipment choices, and tailored installation, we help our clients save real money, month after month.
Why Choose a Wall-Mounted Heat Pump for Your Comfort Needs?
The energy efficiency of wall-mounted heat pumps is based on Inverter technology, which adjusts the unit’s power according to demand. Unlike traditional systems that operate in an on/off mode, the wall-mounted heat pump continuously modulates its speed, significantly reducing consumption.
Our practical tips to make the most of this advantage:
-
Choose a model with high energy efficiency ratings (e.g., SEER > 20, HSPF > 10).
-
Install the indoor unit in a central, open area.
-
Ensure the home is well insulated, especially around windows and in the attic.
-
Program the unit according to real occupancy periods.
Case Study: An Optimized Installation in Laval
Recently, we helped a retired couple in Laval looking to lower their annual heating costs. After a free energy evaluation, we installed a Fujitsu KZAH 12,000 BTU wall-mounted heat pump with a performance coefficient (COP) of 4.2. The installation included:
-
A reinforced wall mount in a cathedral-ceiling living room.
-
An extended 10-meter piping run, carefully hidden.
-
A silent condensate pump to avoid dripping on the terrace.
The result: a 52% reduction in their annual energy consumption, with improved comfort even at -25 °C.
Choosing the Right Location: A Key to Efficiency
The installation has a critical impact on overall performance. Too often, we see units placed too high or facing a heat source. Our certified installers always consider:
-
The natural airflow in the room.
-
Sunlight exposure.
-
The absence of thermal or visual obstacles (e.g., heavy curtains, large furniture).
-
The optimal distance between the indoor and outdoor units.
AirGreen’s tip: Always leave at least 15 cm between the unit and the ceiling to encourage air circulation and make maintenance easier.
HVAC Maintenance: The Key to Maintaining Low Consumption
Even the best wall-mounted heat pump will lose efficiency without regular maintenance. We offer every client an annual maintenance plan that includes:
-
Deep cleaning of filters and coils.
-
Inspection of electrical connections and refrigerant levels.
-
Compressor testing and temperature sensor calibration.
We've found that a poorly maintained unit can use up to 30% more energy for the same comfort level.
Available Grants: How to Lower Installation Costs
Another important lever to quickly recoup your heat pump investment is through government grants. Many of our clients have benefited from:
-
The Hydro-Québec LogisVert program (up to $2,172 for select models).
-
Rénoclimat incentives for well-insulated single-family homes.
-
Local rebates available in Longueuil and Brossard.
AirGreen handles all the paperwork, including forms and compliance documents.

Real Example: A Home in Saint-Bruno-sur-le-Lac
In a single-family home in Saint-Bruno, we recently replaced three old, power-hungry portable air conditioners with two Gree Extreme 12,000 BTU wall-mounted heat pumps. Thanks to a dual parallel installation, we were able to:
-
Optimize airflow in the main living areas.
-
Keep noise levels below 40 dB.
-
Cut their electricity bill by $1,150 in the first year.
All completed in less than 6 hours of work with a two-person team of certified technicians.
Tips to Extend the Life of Your Unit
Here are our 5 key recommendations:
-
Never shut off the unit’s power supply during the winter.
-
Keep the outdoor unit’s exhaust clear (no snow, leaves, or debris).
-
Clean filters every 4 to 6 weeks.
-
Avoid extreme temperature settings (e.g., 17 °C in summer or 30 °C in winter).
-
Call a professional at the first signs of performance drop.
These simple habits help preserve your system’s efficiency and avoid costly repairs.
