As a general rule:9,000 BTU → up to approximately 700 sq ft12,000 BTU → up to approximately 1,000 sq ft18,000 BTU → up to approximately 1,500 sq ft24,000 BTU → up to approximately 2,000 sq ftHowever, surface area is only one factor among others. Insulation, ceiling height, sun exposure, number of floors, and room layout all influence the choice of capacity.An oversized or undersized heat pump can reduce efficiency, increase energy consumption, and decrease comfort.We perform a precise calculation during your free quote in order to recommend the appropriate capacity for your home.

The price varies depending on the power (BTU), the brand chosen and the complexity of the installation.On average, a 12,000 BTU wall-mounted heat pump starts at around $2,800 to $3,000 installed. An on-site assessment will provide a precise price for your location.

Yes. Modern, high-efficiency wall-mounted heat pumps are designed to operate in very cold weather. Several "cold climate" models maintain good heating capacity down to -20°C to -25°C.Some advanced models can even operate in temperatures as low as -30°C to -37°C . However, their heating capacity gradually decreases as the outside temperature drops.It is therefore essential to choose an appliance adapted to the Quebec climate and correctly sized. High-performance models at low temperatures are also eligible for enhanced subsidies under the LogisVert program.We only recommend systems designed for harsh winters to ensure year-round comfort and performance.

How long does a wall-mounted heat pump last?Lifespan varies depending on the quality of the model and maintenance.Entry-level models typically have an average lifespan of 8 to 12 years .High-end models known for their reliability can last 15 years or more , when properly maintained.Professional installation and regular maintenance play an essential role in the performance and longevity of the device.

Several high-efficiency heat pumps are eligible for Hydro-Québec's LogisVert program. Eligibility depends on the installed model, its energy efficiency (SEER/HSPF), and compliance with the program requirements.Heat pumps installed on or after November 26, 2025 must be ENERGY STAR® certified to be eligible for financial assistance.The amount of the subsidy is calculated according to the heating capacity of the appliance at -8°C :$50 per 1,000 BTU for eligible standard heat pumps$120 per 1,000 BTU for heat pumps eligible for the bonus (cold climate)We install models that meet current criteria and support you throughout the process to maximize available financial assistance.
