Fine-Tune Your Wall-Mounted Heat Pump and Significantly Lower Your Energy Costs in Québec
At AirGreen, we’ve helped hundreds of clients across Montréal, Laval, Longueuil, as well as the North Shore and South Shore, who were looking to reduce their electricity bills. One of the most effective — yet often overlooked — tips is properly setting the temperature on your wall-mounted heat pump. In this article, we share our hands-on expertise to show you how a simple adjustment in settings can cut your energy bills by up to 40%, all while improving your indoor comfort.
Why Temperature Settings Play a Key Role in Energy Consumption
A wall-mounted heat pump works by balancing the target temperature with the effort required to reach and maintain it. If you set your unit too low in summer or too high in winter, you’re forcing the system to work harder than necessary, which:
-
Increases your electricity consumption.
-
Reduces the compressor’s lifespan.
-
Causes short cycling (frequent starts and stops), which is harmful over time.
Our key tips:
-
In summer, don’t set the temperature below 24°C indoors.
-
In winter, aim for 21°C during the day, 19°C at night.
-
Use the "Auto" mode to let the unit intelligently manage temperature fluctuations.
Case Study: A Smart Adjustment in Longueuil
Ms. P., owner of a bungalow in Longueuil, contacted us because her electricity bill skyrocketed after installing a Sharp ZU1 18,000 BTU wall-mounted heat pump. After our inspection, we learned she was constantly setting her unit to 17°C in the summer and 27°C in the winter, forcing the system to compensate for major thermal gaps.
What we did:
-
Reprogrammed her remote for optimized cycles.
-
Activated the energy-saving mode.
-
Gave a quick lesson on using the different operating modes.
Result: 38% savings on her Hydro-Québec bill the following month.
The Impact of Short Cycling on Your HVAC System’s Longevity
Extreme settings cause what’s known as “short cycling” — when the heat pump starts and stops frequently. This behavior drastically shortens the system’s lifespan.
Signs of short cycling:
-
Frequent startup noises.
-
Inconsistent airflow.
-
Fluctuating indoor temperatures.
At AirGreen, we recommend setting a schedule for your temperature settings: for example, 21°C from 6 a.m. to 11 p.m., then 18°C at night. This avoids abrupt changes and limits wear on internal components.
Testimonial: A Condo in Laval Transformed with Proper Programming
In a condo located in Laval, a retired couple had a Gree Extreme 12,000 BTU heat pump installed. While they were happy with the comfort, they noticed a significant increase in their electricity bill.
After our visit:
-
Night mode was programmed to automatically reduce the temperature by 3°C.
-
Fan speed was set to “Low” during quiet hours.
-
We explained how humidity affects perceived comfort.
Two months later, they reported a 31% energy savings and more stable indoor temperatures in their living space.
Practical Tips for Optimizing Your Wall-Mounted Heat Pump Settings
Here are a few simple and effective actions to cut your energy consumption:
-
Don’t drastically change the temperature — adjust by 1 or 2 degrees at a time.
-
Avoid the “Turbo” mode unless it’s for guests or during extreme heat.
-
Use the timer function to align temperature changes with your daily routine.
-
Close doors to unused rooms to reduce thermal load.
-
Keep filters clean — dirty filters force the fan to work harder.
Understanding Temperature Differences Between Rooms
In some homes, even with a quality HVAC installation, temperatures can vary from room to room. This leads some people to overcompensate by adjusting the heat pump settings.
Our solutions:
-
Add a second wall-mounted unit in under-covered zones.
-
Install a smart thermostat to automatically balance temperatures.
-
Check insulation and seal air leaks.
AirGreen offers inspection visits to evaluate whether a system adjustment or modification is needed.
Recommended Seasonal Settings: Our Guidelines

| Winter | 20 to 21°C | Program to drop to 18°C at night |
| Mid-season | Auto Mode | Let the heat pump manage heating/cooling shifts |
Following these tips helps you avoid energy waste and extends the lifespan of your system.
