Why Your Wall-Mounted Heat Pump Drastically Increases Your Electricity Bill During Montréal Summers: 5 Surprising Reasons Revealed by AirGreen
Summer in Montréal means heat, humidity, and prolonged periods of intensive use of wall-mounted heat pumps. At AirGreen, recognized specialists in HVAC installation in Montréal, Laval, Longueuil, as well as on the North Shore and South Shore, we frequently observe that many customers are surprised by the rise in their energy consumption during summer. However, several often overlooked factors can explain why your heat pump consumes so much during this critical period.
Here are the five most common and surprising reasons we've identified through extensive real-world experience.
Your wall-mounted heat pump is improperly sized for your space
Incorrect sizing of a heat pump is one of the main reasons for excessive energy consumption. At AirGreen, we recently intervened in Laval, where a customer was using a 12,000 BTU heat pump to cool a 1,500-square-foot home. This improperly sized installation forced the unit to run continuously at full power without ever reaching the desired temperatures. Result: excessive electrical consumption and premature wear on the equipment.
To avoid this issue, it's crucial to call on qualified experts like our team at AirGreen, who perform a detailed analysis of your space, considering various factors (building orientation, insulation, number of windows) to select the ideal model for your home.
Insufficient or neglected HVAC maintenance
Inadequate maintenance often results in reduced performance and increased energy consumption. We regularly encounter situations, notably on the South Shore, where simply cleaning or replacing air filters significantly reduces energy use.
For example, during a recent intervention in Longueuil, we observed an immediate improvement in the energy efficiency of an 18,000 BTU Gree Sapphire wall-mounted heat pump after conducting thorough maintenance. The customer noticed a significant drop in their electricity bill starting the following month.
Poor thermal insulation of your home
If your Montréal home is poorly insulated, the heat pump will need to run continuously to compensate for significant thermal losses. This common issue in older or poorly renovated homes results in disproportionate energy consumption, especially during intense heat waves.
AirGreen regularly advises customers to improve thermal insulation before proceeding with a new HVAC installation. By combining effective insulation with a premium-quality wall-mounted heat pump such as those offered by Fujitsu or Lennox, summer bill savings can reach up to 40%.
Incorrect use of heat pump settings
Many users incorrectly adjust their wall-mounted heat pumps, leading to unnecessary excess electrical consumption. At AirGreen, we always recommend that our customers in Montréal, Laval, Longueuil, as well as on the North Shore and South Shore, set indoor temperatures reasonably (between 23 and 25°C). Each degree below this range can increase your monthly energy bill by up to 5%.
During a recent installation in Montréal-Nord, we equipped a customer with a 24,000 BTU Sharp heat pump. After correctly adjusting settings and educating the customer about optimal use, they immediately saw about a 20% monthly reduction in their electricity consumption.
Outdated or energy-inefficient wall-mounted heat pump
Older models or low-end units, although seemingly affordable at purchase, often prove costly in the long run due to poor energy efficiency. A lower-quality wall-mounted heat pump can double your summer electricity bill compared to an efficient Energy Star-certified model.
AirGreen recently replaced an old heat pump in Montréal with a highly efficient model, the Fujitsu Halcyon 18,000 BTU heat pump. This installation allowed the customer to immediately reduce electricity consumption by 35%, while also qualifying for a $1,704 grant through Hydro-Québec’s LogisVert program.
