Question 1: How well insulated is my home?
Before entering the world of heat pumps, it is crucial to evaluate the state of insulation of your home. A poorly insulated home not only consumes more energy, but also provides less comfort, regardless of the heating system. Reducing energy needs through insulation can be the first step toward a more efficient and economical home.
Question 2: What heating solution do I currently have in my home?
Identifying your existing heating system is essential to determine the most appropriate choice. From boilers to hydronic systems with radiators, every situation can influence the choice between an air-to-water or air-to-air heat pump.
If, for example, your home is heated exclusively with electricity, you can only opt for an aerothermal heat pump, as it is quite expensive to create a hydronic heating network with radiators or underfloor heating in a renovation project.
Question 3: What needs do I want to satisfy?
Heating, cooling, hot water, all three?
Depending on the answer, some heat pumps will be more suitable than others, as we have seen.
- With an Air/Water heat pump, if you have compatible underfloor heating, it can also be used to cool the house in summer.
- With an Air/Air heat pump, they are now all reversible, so they can provide heating in the winter and air conditioning in the summer.
Determining whether you are looking for heating, cooling, hot water or a combination of these factors is crucial to choosing the right heat pump.
Question 4: Do I have a suitable location for the outdoor unit?
The location of the outdoor unit is key to minimizing noise pollution and ensuring optimal heat pump operation.
Whichever type of heat pump you choose, you will need a suitable location to install the outdoor unit. Your installer will be able to advise you on the best location to minimize noise pollution caused by vibrations from the machine during operation.
Here are some tips:
- Choose an ideal location on the outside wall of a little-traveled room (a garage, a laundry room, i.e., avoid a bedroom).
- Avoid locations too close to neighbors.
- Ideally, install the generator on the ground, on a concrete slab provided for this purpose and therefore separate from the wall of your house, rather than on a chair installed on one of the walls (wall-mounted frame for outdoor generator).
- Check that the installer provides anti-vibration rubber mounts. There are models for floor installation, or chairs (wall racks) that incorporate anti-vibration pads as standard.
Question 5: What criteria should I check to ensure that the proposed heat pump is suitable for my situation?
Making sure that the heat pump power and capacity are suitable for your home and needs is essential to ensure comfort and energy savings.
- Heat pump power: Heat pump power should be matched to your home, considering factors such as location, climate and level of insulation. It is essential that a professional perform the calculation, but you can verify that a proper technical inspection and sizing study has been carried out. A heat pump that is not powerful enough may not provide sufficient comfort, while one that is too powerful may cause excessive energy consumption.
- Comparison of power ratings: When comparing the power ratings of different heat pumps, be sure to take into account the basic outdoor temperature of your location. Two heat pumps with identical catalog ratings may not provide the same output at low temperatures, which affects the actual performance of the heat pump.
- Heating water temperature: It is crucial to consider the water temperature required for your radiators or underfloor heating. Each type of heat emitter has different temperature requirements, and the capacity of the heat pump must be adapted accordingly. Check with your installer to verify the heat pump's ability to produce water at the right temperature for your heating needs.
Question 6: Do I have an adequate electricity meter?
A heat pump uses electricity to operate. So you should check that the type of electricity supply you choose is compatible with your meter. For example, if you have a three-phase meter, you will need to choose a heat pump that works with a three-phase supply.
The meter power must also be adequate, as the heat pump will need a lot of power, especially when starting up. For a 100 m² all-electric house, a 12 kVA meter is usually necessary.
Please note that it is possible to change the power or the type of meter if necessary, with possible additional costs.
Question 7: Have the indispensable options been provided for the proper operation of the installation?
Elements such as descaling, decoupling cylinder and proper regulation are essential to optimize the performance and durability of the installation.
Descaling: Before installing an air-to-water heat pump, it is strongly recommended to descale the existing system. This involves flushing the hydraulic system to remove impurities that could damage the new heat pump or affect its performance. The use of an inhibitor product in the circuit water can ensure its quality over time.
Decoupling cylinder: In most renovation projects, it is necessary to add a decoupling cylinder to the system. This component hydraulically separates the primary circuit (of the heat pump) from the secondary circuit (of the heating emitters), allowing each to operate independently under optimal conditions. It also acts as a settling tank to remove impurities and provide greater comfort during defrost cycles.
Regulation: Proper regulation is essential to ensure comfort and optimum performance of the heat pump. It is the installer's responsibility to optimize the regulation settings to suit the specific installation. This may include setting a water law that automatically adjusts the heating water outlet temperature according to the needs and the outdoor temperature. It is also important for the installer to teach the user how to use the thermostat to avoid excessive energy consumption by setting a weekly schedule to avoid wasting energy when not at home or during the night.
Question 8: Is the selected material and installation of recognized quality?
Verifying the quality and certifications of the equipment, as well as the warranty conditions offered, is key to ensure a lasting and effective investment.
You can check if the heat pump has quality certification, such as HP-Keymark or NF PAC or Eurovent. If not, don't bother!
Working with a qualified, RGE-labeled company is crucial to ensure the quality and legality of the work performed.

Question 9: Can I receive a grant to install the heat pump?
Although the initial investment may seem high, renovation work will save you a lot of money on your energy bills, make your home more comfortable and add value to your property.
Explore the financial assistance options available. It can significantly reduce costs and make the transition more affordable.
Question 10: Once the installation is complete, what maintenance should be performed?
To ensure that your machine maintains its performance over time and therefore the savings and comfort you expect, maintenance is essential.
For air/air or air/water heat pumps, the servicing frequency for these heating systems has changed as of July 30, . Overhaul is now mandatory every 2 years or less. This rule applies only to models with power ratings between 4 and 70 kW. This measure applies from the first revision. If, for example, your equipment was installed on July 1, , it must be serviced before July 1, .
These are the main points that will be covered during the interview:
- Checking the general condition of the machine
- Checking the tightness of the refrigeration circuit
- Checking the performance of the plant
- Make the necessary adjustments
- Clean the system if necessary (filter cleaning in the case of an air/air heat pump, for example).
Ask your installer about maintenance contracts.
When choosing a heat pump and planning its installation, it's critical to ask the right questions and consider several key issues. Assessing the insulation condition of your home, knowing your existing heating system, determining your specific needs and making sure you have a suitable location for the outdoor unit are just a few of the crucial points to consider. In addition, it is important to verify the quality of the equipment, installer certification and explore financial assistance options available. Regular maintenance is also essential to ensure the long-term performance of your heat pump and maintain the desired savings and comfort.
How do air source heat pumps work?
Air source heat pumps are the most common heat pump choice for residential heating and cooling. Here’s how they work.
A typical air source heat pump is made up of an outdoor unit connected to an indoor unit by a refrigerant line. In the winter, the outdoor unit draws in air, absorbs its heat and transfers it to a refrigerant fluid. A combination of temperature and pressure transforms this fluid into a gas. The gas then passes through a compressor to increase its temperature further, and the resulting heat is transferred into your home, either directly from the unit or through ductwork.
This process reverses in the summer. The heat pump absorbs heat from inside your home and transfers it to the outdoors, becoming a high-efficiency air conditioner and dehumidifier.
What’s involved in making the switch?
Installing a heat pump is more complex than simply replacing your existing furnace, boiler, baseboards, or other HVAC system. It may involve modifying ductwork and wiring, as well as finding space for an outdoor condensing unit.
If you live in an older home, you should install other energy-efficiency measures first to reduce your heating load. This could include new insulation, air sealing and more. By limiting heat loss from air leaks or thin insulation, you’ll get the most out of your heat pump and may even be able to opt for a smaller, more affordable unit.
Ducted or ductless?
A ducted heat pump works in a similar way to a central furnace. It’s connected to interior ductwork and controlled by a central thermostat. Warm or cool air travels through the ducts and into your home.
A ductless heat pump emits warm or cool air directly from an indoor unit mounted to the wall or floor. Depending on the size and layout of your home, you may need more than one indoor unit.
You might want to opt for a ductless heat pump if you:
- Live in a home with no existing ductwork.
- Want to have flexibility in heating and cooling in multiple areas of your home.
- Need supplemental heating and cooling in a particular area, such as a home addition.
Standalone or hybrid?
As the outside air temperature drops, the heat pump has to work harder, gradually reducing its efficiency and heating capacity. Some homeowners opt for hybrid systems, with a conventional furnace or boiler acting as a backup to a primary air source heat pump. Some choose to install cold climate air source heat pumps, which are specially designed to work in low outdoor temperatures.
The choice of whether to select a standalone or hybrid HVAC system will be dependent on several factors, such as climate, energy costs, heat loss and home type. A licensed HVAC contractor can help assess your home and identify the most energy-efficient and cost-effective solution for you.
Single stage, two stage or variable stage?
A single-stage heat pump is the most basic system available. It uses a simple on/off cycle that is triggered when the temperature dips below a set point. It tends to be the most costly type of heat pump to run, as the only setting is full speed.
A two-stage heat pump has two settings—high and low—allowing for slightly more precise temperature control.
A variable-stage heat pump is the most advanced system available. It is able to monitor and adjust to a full range of speeds to maintain the desired indoor temperature. Since it only uses as much power as it needs, it is the most energy-efficient option.
How to find the right contractor
Replacing your home's HVAC system is a big undertaking. If you’ve decided a heat pump is the right choice for you, the next step is finding a qualified, licensed contractor. They can help you make the best purchasing decision for your home to meet your needs. In Ontario, HVAC contractors must be registered with the Technical Standards and Safety Authority.
