Heating

What is a heat pump and how does it work?

A heat pump is a heating and cooling system that works by moving heat rather than generating it. In winter, it extracts thermal energy from the outdoor air (even in cold weather) and transfers it inside your home. In summer, it reverses the process to cool your space. This dual role makes it a particularly efficient and cost-effective piece of equipment. Unlike a furnace that burns fuel to produce heat, a heat pump moves energy, allowing it to generate up to three times more heat than the electricity it consumes.

What is the difference between a wall-mounted and a central heat pump?

A wall-mounted heat pump (or mini-split) consists of an outdoor unit and one or more indoor wall units. It’s ideal for heating or cooling a specific room or space without touching your existing ventilation system. It’s generally easier and less expensive to install. A central heat pump uses your home’s existing duct network to distribute heat or cool air throughout all rooms. It’s better suited to homes already equipped with ducts. The right choice depends on your home type, budget, and comfort needs.

How much does it cost to install a heat pump in Quebec?

Installation costs vary depending on several factors: the type of unit (wall-mounted or central), the required BTU capacity, the complexity of the installation, and the brand chosen. Generally, a single-zone wall-mounted heat pump ranges from $3,000 to $6,000 installed, while a central system can reach $8,000 to $15,000 or more depending on configuration. These costs can be significantly reduced through available rebate programs, including Hydro-Quebec’s LogisVert program, which can cover up to $6,700 of the installation. Contact us for an accurate estimate tailored to your situation.

What is the best heat pump brand?

There is no single “best” brand: the right choice depends on your specific needs, budget, and building type. Among the recognized brands on the Quebec market are Daikin, Mitsubishi, Carrier, Lennox, and Fujitsu, all known for their reliability and energy efficiency. Some models are specifically optimized for Quebec winters and can operate effectively down to -30°C. At Ventilation Hitech, we help you choose the equipment best suited to your home and budget, taking into account rebate program requirements.

How many BTUs do I need to heat my home?

The number of BTUs needed depends on the area to be heated, the insulation level, the climate zone, and ceiling height. As a general rule, an estimate of 20 to 30 BTU per square foot applies in Quebec, but this figure can vary considerably. For example, a well-insulated 1,500 sq ft home in Laval might require between 30,000 and 45,000 BTU. A technical assessment is needed to determine the exact capacity required and avoid over- or under-sizing the unit, which harms efficiency and equipment lifespan.

At what temperature does a heat pump stop working efficiently?

Traditional heat pumps lost efficiency when temperatures dropped below -15°C to -20°C. New generation models, often called “cold climate heat pumps,” maintain satisfactory efficiency down to -25°C, or even -30°C for premium models. In Quebec, it’s recommended to choose a unit certified for local winter temperatures. On particularly cold nights, an integrated electric backup takes over automatically. Consult us to choose a model suited to the Laval and North Shore climate.

Can I get rebates for heat pump installation?

Yes, several financial assistance programs are available in Quebec for the installation of an eligible heat pump. Hydro-Quebec’s LogisVert program offers assistance based on the unit’s heating capacity, reaching up to $6,700 for an ENERGY STAR-certified central heat pump. For homes currently heated with oil, the federal CAMT program (Oil-to-Heat-Pump Affordability) can provide additional assistance of up to $10,000 for eligible households. Complementary programs may also apply for Énergir customers wishing to adopt a bioenergy system. It’s important to obtain approval before starting work for certain programs. Ventilation Hitech can guide you through all these steps.

Heat pump or furnace: which should I choose for my home?

A heat pump is generally the most cost-effective long-term choice in Quebec, especially with Hydro-Quebec’s electricity rates. It provides both heating and cooling in a single system and benefits from significant rebates. A natural gas furnace may be more economical for very large or poorly insulated homes in extremely cold weather, but it doesn’t cool and generates GHG emissions. A hybrid solution combining a heat pump with a gas backup (also called bioenergy) is often the most efficient for homes already equipped with a duct system and access to natural gas. Your choice depends on your home type, insulation, current energy source, and budget.

What is bioenergy and how is it different from a heat pump?

Bioenergy (or dual energy) is a hybrid heating system that combines an electric heat pump with a natural gas furnace (Énergir). The heat pump handles heating most of the time, taking advantage of its superior efficiency. When temperatures drop very low, generally below -15°C to -20°C, or during peak periods when electricity costs more, the natural gas furnace automatically takes over. You get the best of both systems: reduced electricity consumption in the depths of winter, and total reliability even during extreme cold. Ventilation Hitech has been installing bioenergy systems since 2005, in partnership with Énergir.

Is bioenergy a good option for my home?

Bioenergy is particularly advantageous for homes already connected to the natural gas network (Énergir) and equipped with a duct system. It’s ideal for homeowners who want to reduce their electricity bill during extreme cold without sacrificing comfort or reliability. If you already have a gas furnace and want to add a heat pump, converting to a bioenergy system is often the most logical and cost-effective solution. If you don’t have access to natural gas, a heat pump alone with an integrated electric backup is generally the best option.

Is bioenergy eligible for rebates?

Yes. Bioenergy systems may qualify for Hydro-Quebec’s LogisVert program for the heat pump component, and for Énergir’s financial assistance programs for customers connected to the natural gas network. Amounts and conditions vary depending on the equipment installed and your situation. Our team can help you determine your eligibility and maximize available assistance during your free estimate.

How do I maintain my heat pump?

Regular maintenance extends the life of your heat pump and maintains its efficiency. For homeowners: clean the indoor unit filters every one to two months, and keep the outdoor unit free of ice, snow, and vegetation. For professional service: an annual check-up by a certified technician is recommended. This service includes checking refrigerant levels, inspecting electrical connections, cleaning coils, and verifying the overall operation of the system. At Ventilation Hitech, we offer maintenance contracts to keep your equipment running properly.

Why has my heat pump stopped heating?

Several reasons may explain why a heat pump is no longer heating properly: clogged filters blocking airflow, low refrigerant level (leak), an outdoor unit covered in ice or obstructed, an electrical or thermostat issue, or an undersized unit for current temperatures. In winter, some frost buildup on the outdoor unit is normal (the defrost cycle handles it), but a thick layer of ice may indicate a problem. If your heat pump blows lukewarm or cool air in heating mode, contact a qualified technician. Do not attempt to manually defrost the unit with tools.

Should I turn off my heat pump in winter?

No. Modern heat pumps are designed to run in winter and are your primary heating system. Turning them off in winter is a common mistake. Some homeowners mistakenly believe they should be shut down in very cold weather, but recent models designed for Quebec maintain their efficiency down to -25°C or -30°C. Stopping and restarting the heat pump during cold snaps puts more strain on the system and can reduce its lifespan. Let your heat pump run normally and trust the integrated electric backup to take over on the coldest nights.

What is the lifespan of a heat pump?

A properly maintained heat pump typically lasts 15 to 20 years. Several factors influence its longevity: the quality of the initial installation, the regularity of maintenance (filters, coils, refrigerant levels), intensity of use, and the brand quality. Systems that are under- or over-sized for actual needs wear out faster. If your heat pump is more than 12 to 15 years old and showing signs of weakness (poor performance, noise, leaks), it may be more cost-effective to replace it than to repair it.

Air Conditioning

What is the difference between a wall-mounted AC and a central system?

A wall-mounted air conditioner (mini-split) cools one or more specific rooms via a wall unit, with no ducts required. It’s ideal for homes without a centralized ventilation system, additions, or spaces that are hard to cool. A central air conditioning system distributes cool air throughout the home via the existing duct network, providing uniform comfort in every room. It’s better suited to homes with ducts and those who want an invisible, integrated solution. Wall-mounted units are generally less expensive to install; central systems offer more consistent comfort across the entire property.

Heat pump or air conditioner: which should I choose for my home?

A heat pump is a two-in-one system that heats in winter and cools in summer. A traditional air conditioner only cools. If you’re looking to replace or supplement your heating system while installing cooling, a heat pump is generally the most cost-effective long-term solution. It also benefits from more generous government rebates. If you already have an efficient heating system and only need cooling, a central or wall-mounted air conditioner may be sufficient. Discuss your situation with our team for the best recommendation.

How many BTUs do I need to cool my home?

The general rule in Quebec is about 20 BTU per square foot for cooling, but this varies depending on your home’s sun exposure, number of windows, insulation level, ceiling height, and number of occupants. Undersizing leads to a unit that runs continuously without ever reaching the desired temperature. Oversizing creates short cycles that generate humidity and premature wear. A Ventilation Hitech technician can perform an accurate load calculation (Manual J or equivalent) to determine the ideal capacity for your situation.

What is the SEER rating and why does it matter?

The SEER (Seasonal Energy Efficiency Ratio) measures the energy efficiency of an air conditioner over an entire season. The higher the SEER, the more efficient the unit and the less electricity it consumes for the same level of cooling. In Canada, the minimum standard is 14 SEER for units sold since 2023. High-end models reach 20 to 25 SEER or more. To qualify for Hydro-Quebec’s rebate programs (LogisVert), units must meet a minimum SEER rating published in the list of eligible equipment. A higher SEER means real savings on your electricity bill over time.

How do I maintain my wall-mounted air conditioner?

Maintaining a wall-mounted AC involves two parts. For homeowners: clean the indoor filters every 2 to 4 weeks during heavy use. These filters come out easily and can be rinsed with warm water. Also keep the outdoor unit clear of vegetation, leaves, and debris. For professional maintenance: an annual cleaning by a qualified technician is recommended to clean indoor and outdoor coils, check refrigerant levels, and inspect electrical connections. A well-maintained unit consumes less energy and lasts longer.

Why is my air conditioner not cooling enough?

The most common causes of an air conditioner that no longer cools adequately are: clogged filters blocking airflow, low refrigerant level (indicating a leak), an outdoor unit obstructed by vegetation or dirt, a poorly calibrated thermostat, or an aging unit. In very hot and humid weather, an air conditioner may seem less efficient: this is normal, as it’s working harder. If your unit is blowing warm air with the thermostat correctly set, contact a technician. Checking refrigerant levels legally requires a certified technician in Quebec.

Why is my air conditioner leaking inside?

A wall-mounted air conditioner leaking inside typically indicates a drainage problem. Main causes: a blocked or clogged drain line (algae, deposits), a full or cracked condensate pan, an improperly leveled installation that prevents water from draining properly, or a refrigerant level too low causing the coils to freeze. In all cases, water leaking inside should be checked quickly to prevent damage to your wall or floor. Do not continue using the unit if the leak is significant.

How do I know if my AC is low on refrigerant?

Signs of low refrigerant (also called “gas” or coolant) include: insufficient cooling despite the unit running normally, frost or ice on the outdoor unit or copper pipes, a bubbling or hissing sound from the unit, and a noticeable increase in your electricity bill. It’s important to know that refrigerant is not “consumed”: if the level is low, there is a leak. Recharging without repairing the leak is not a permanent solution. Only a certified technician can handle refrigerants in Quebec.

How much does air conditioning installation cost?

Costs vary depending on the type of system, the area to cool, and the complexity of the installation. A single-zone wall-mounted air conditioner installed typically ranges from $2,500 to $5,500. A multi-zone system (multiple rooms) can reach $8,000 to $12,000 or more. A central air conditioning system (using existing ducts) often falls between $4,000 and $10,000 depending on the home’s configuration. If you choose a heat pump rather than a simple air conditioner, rebates of up to $6,700 may apply, making the heat pump more affordable than a standard air conditioner.

How often should I have my air conditioner serviced?

Professional annual maintenance is recommended for most cooling systems, ideally in spring before the warm season. This service includes cleaning indoor and outdoor coils, checking refrigerant levels, inspecting electrical connections, cleaning or replacing filters, and checking drainage. In addition, homeowners should clean filters every 2 to 4 weeks during the season. Regular maintenance can extend the unit’s lifespan by several years and maintain energy efficiency.

What is the lifespan of an air conditioner?

A well-maintained air conditioner or heat pump can last 15 to 20 years. Recognized-brand wall-mounted units typically reach 15 to 18 years with regular maintenance. Central systems have a similar lifespan. Factors that shorten lifespan: poor initial installation, irregular maintenance, over- or under-sizing, and severe usage conditions. If your unit is more than 12 years old, showing signs of weakness, and repairs are accumulating, a replacement assessment is often the most cost-effective long-term decision.

Are there rebates for air conditioning in Quebec?

Direct rebates for cooling alone are limited. Most programs, including Hydro-Quebec’s LogisVert, target heat pumps, which provide both heating and cooling. If you’re considering installing a cooling system, choosing a heat pump over a simple air conditioner gives you access to assistance of up to $6,700 while also getting a system that heats your home in winter. This is often the most financially advantageous decision. Contact our team for a complete, personalized assessment.
