Wall-Mounted Heat Pumps and the Québec Winter: How to Ensure Optimal Performance Even at -25°C

The Québec winter can be a challenge for HVAC system owners, especially those who have opted for wall-mounted heat pumps. These units are known for their energy efficiency and performance even in freezing temperatures. However, how can you ensure that a wall-mounted heat pump operates at its optimal performance even when it’s as cold as -25°C? At AirGreen, we have the expertise to guarantee that your system performs flawlessly throughout the winter. In this article, we explore the factors to consider to maximize the performance of your wall-mounted heat pump during the harsh Québec winter.

Wall-Mounted Heat Pumps: The Optimal Choice for the Québec Climate

Wall-mounted heat pumps are all-in-one heating and cooling systems that offer an efficient and cost-effective solution for controlling indoor temperatures year-round. They are particularly suited for cold winters due to their ability to capture heat from the outside air, even in freezing temperatures, and redistribute it indoors.

How Wall-Mounted Heat Pumps Work in Cold Weather

One of the main advantages of wall-mounted heat pumps is their ability to operate at low temperatures. Even when the outside temperature drops well below freezing, the heat pump can extract the heat available in the outside air and transfer it inside. However, there are certain limits to this efficiency, especially when temperatures drop below -25°C.

At such extreme temperatures, the heat pump’s ability to maintain optimal performance can be affected. This is because the amount of heat available in the outside air decreases, forcing the unit to work harder to maintain a comfortable indoor temperature. However, more advanced models, such as those offered by brands like Fujitsu, Gree, and Bosch, are specifically designed to handle these challenges.

Choosing the Right Heat Pump for the Québec Winter

When installing a wall-mounted heat pump to withstand the extreme winter temperatures, it’s essential to choose the right model and brand. Here are some key factors to consider:

  1. BTU and Heating Capacity: It’s crucial that the heat pump is suited to the size of your space and the heating needs specific to your region. For example, an 18,000 BTU unit may be sufficient for a medium-sized home, but for larger spaces or poorly insulated homes, units with 24,000 BTU or more may be necessary.

  2. Energy Efficiency: Modern heat pumps are increasingly efficient, even at low temperatures. It’s important to choose a wall-mounted heat pump with a high coefficient of performance (COP) at low temperatures. Recent models from Gree, Fujitsu, and Bosch offer high performance even down to -25°C and beyond.

  3. Defrost Technology: An effective defrost function is essential when the heat pump operates in freezing temperatures. Units equipped with this technology prevent ice from forming on the coils, ensuring consistent performance.

  4. Brand and Reliability: Choosing a reputable brand, such as Fujitsu, Gree, or Bosch, ensures quality and durability. These manufacturers offer models designed to withstand the Québec winter, with robust components and excellent after-sales service.

Maintaining Your Wall-Mounted Heat Pump in Winter

Regular maintenance is essential to ensure that your wall-mounted heat pump operates at peak performance, especially during the coldest months. Here are some tips for maintaining your unit:

  1. Cleaning the Filters: Filters should be cleaned or replaced monthly, especially during the winter when the unit is running at full capacity. A clogged filter can reduce the efficiency of your heat pump and increase energy consumption.

  2. Inspecting the Outdoor Unit: Ensure that the outdoor unit of the heat pump is free from snow, ice, and debris. If these elements block the airflow, the unit’s performance will be reduced.

  3. Checking the Defrost System: Make sure the defrost system is working properly. If ice accumulates on the coils, it will prevent the unit from operating efficiently.

  4. Annual Inspection by a Professional: An annual inspection by a professional can detect and resolve issues before they become critical. Our technicians at AirGreen specialize in the maintenance and repair of wall-mounted heat pumps, ensuring optimal performance.
