Poor thermostat management in winter can turn a comfortable home into a real energy sink. In Laval, where winters are harsh and prolonged, thermostat misuse is common. Too often, these simple actions cost a lot in electricity, reduce the lifespan of HVAC equipment, and compromise indoor comfort. At AirGreen, we regularly work in Laval homes and businesses where simple adjustments could have prevented service calls. In this article, we share with you the most common mistakes related to the thermostat in winter, and above all, our professional solutions to correct them effectively.
Why Proper Thermostat Management Is Essential in Laval
In a region like Laval, where winter temperatures can drop well below freezing for several weeks, the thermostat’s role becomes central to the performance of your heating system. Poor use not only leads to higher energy costs but can also disrupt the proper functioning of heat pumps, forced-air systems, and electric heaters that we install for our clients.
At AirGreen, we have seen all kinds of cases: from thermostats poorly placed in drafty areas to programming that doesn’t match occupants’ lifestyles. Each time, our specialized technicians have provided concrete solutions that are simple to apply but effective in the long term.
Mistake #1: Turning the Thermostat Up Suddenly When Coming Home
This is one of the most common reflexes: coming into a cold house and raising the temperature to 25°C thinking it will warm the room faster. However, this does not heat faster, but unnecessarily forces your HVAC system to work at full capacity.
✅ The AirGreen Solution
We recommend smart thermostat programming based on occupancy schedules. For example, we install smart thermostats compatible with wall-mounted and central heat pumps such as the Fujitsu KZAH R-32, Goodman R-32, or Bosch BIVA IDS Premium R-454B models, which automatically adjust the temperature according to occupants’ habits.
Mistake #2: Frequently Changing Settings Manually
Changing the temperature multiple times a day or based on mood disrupts your heating device’s natural cycle, which reduces its energy efficiency.
✅ The AirGreen Approach
During our installations in Laval, we systematically offer to set a stable and adapted temperature curve. Our technicians demonstrate how to optimize the heating cycle considering the building’s thermal inertia. A stable temperature around 21°C during the day and 18-19°C at night is often ideal to maximize comfort and energy efficiency.
Mistake #3: Placing the Thermostat Near a Heat or Cold Source
A poorly positioned thermostat (near a window, radiator, or in a poorly insulated hallway) skews temperature readings and triggers inappropriate heating cycles.
✅ Proper Positioning by AirGreen
Our installers always assess the best location for the thermostat. In winter in Laval, we often reposition thermostats initially placed in areas exposed to cold or heat to ensure a reliable measurement of the ambient temperature.
Mistake #4: Ignoring Specific Modes for Heat Pumps
Some users activate the "auxiliary" or "emergency" mode without understanding its implications, which causes energy consumption to skyrocket in winter.
✅ Our Recommendations
When we install a central or wall-mounted heat pump, such as Gree, Fujitsu, or Bosch models, we always explain how the different heating modes work. The "Emergency" mode should only be used in case of main system failure. Our systems compatible with cold climate heating (down to -30 °C for some models like the Gree Extreme) allow staying in heat pump mode longer without resorting to auxiliary electricity.
Mistake #5: Not Using Connected Features
Many homes in Laval now have connected thermostats but do not utilize their smart features, including geolocation, routine learning, or automatic adjustment based on outdoor conditions.
✅ Our Expert Advice
At AirGreen, we configure smart thermostats to adapt to your schedules, absences, and outdoor weather. Thanks to this setup, our clients save on average between 10% and 25% on their electricity bills in winter.
Concrete Result: Example of a Case in Laval
A client in Chomedey, Laval, had a Sharp ZU1 18,000 BTU wall-mounted heat pump installed by another contractor. He complained about a lack of heat. During our diagnosis, we discovered that the thermostat was placed just above an electric convector, skewing the temperature measurement.
We repositioned the thermostat, reprogrammed the cycles according to the client’s habits, and adjusted the heat pump’s airflow. Result: increased comfort, 22% reduction in energy consumption, and total satisfaction. This kind of intervention clearly illustrates our technical expertise and personalized approach in all our work in Laval and surrounding areas.
Additional Tips to Optimize Thermostat Use in Winter
-
Regularly check your thermostat’s calibration.
-
Use thermal curtains to better insulate rooms.
-
Adjust temperatures by room (e.g., cooler bedrooms, warmer living rooms).
-
Consider multi-zone zoning for large houses.
