Equipping your home with a heat pump keeps your indoor temperature ideal all year round, while substantially lowering your electricity consumption. But with so many different models on the market, how do you know which one is right for you? Here are five useful tips to help you choice.

1. Assess your heating and cooling needs

There are a few things you need to consider before heading to the store. Namely, just what are your heating and cooling needs? Various factors will come into play here: your home’s surface area and how well it’s insulated, your geographical location and the local climate. If you live in an area with harsh winters, you’ll need a unit that’s powerful enough to operate efficiently in very cold weather.

2. Distinguer les types de thermopompes

Air‑to‑air, air‑to‑water, geothermal: there are three kinds of heat pump, each with its own advantages and disadvantages. We’ve summarized them, below:

  • Air-to-air heat pumps use the outdoor air as a source of thermal energy in heating mode, and as a sink in which to reject energy when in cooling mode. These are the most common models. However, while well suited to more temperate regions, they are less effective in places with extremely low temperatures.
  • Air-to-water heat pumps work much like air-to-air models, with one major difference: the thermal energy captured is transferred to water, which then circulates through a centralized system. They are suitable for colder climates and require a hydronic (water-based) distribution system.
  • Geothermal heat pumps use the relatively constant temperature underground as the thermal exchange medium in heating and cooling modes. Although geothermal systems are more expensive to install, the investment pays off: savings of more than 60% on heating costs compared to traditional systems, a lifespan of up to 20 years, ease of maintenance and versatility, to name but a few of their attributes.

3. Choose a more energy efficient model

To maximize your investment, aim for maximum energy efficiency. Below are two helpful indicators:

  • The SEER (Seasonal Energy Efficiency Ratio) rating, which is the ratio of cooling output during a typical cooling season to the total energy consumed during the same period.
  • The HSPF (Heating Seasonal Performance Factor) rating, or the ratio of the heat produced by the unit during a typical heating season to the electricity it uses.

Units with higher ratings are more energy efficient—and that’s exactly what you’re looking for.

Certain efficient heat pumps are more efficient during very cold weather. They’re called high-efficiency heat pumps.

High-efficiency heat pumps can:

  • generate savings of up to 40% on your electricity bills during heating season
  • provide more constant heat and greater comfort
  • reduce the strain on the power grid during peak demand periods, which benefits all Hydro‑Québec customers

4. Consider the added features

Some heat pumps have additional features like premium air filters, programmable controls and a quiet operation mode. Consider your preferences and the options that make the most sense for your lifestyle.

5. Get in touch with the experts and benefit from the LogisVert program

Call on a specialist who can assess your needs, recommend the most suitable model and install the unit so as to guarantee its optimal performance.

Don’t forget that Hydro‑Québec’s LogisVert Efficient Homes Program offers up to $6,700 in financial assistance for certain models—a serious boost that will make your purchase even more advantageous. Not to mention the substantial and recurring savings you’ll enjoy on your electricity bill, thanks to your new heat pump!

Everything You Need to Know About Geothermal Heat Pumps

Heat pumps are some of the most energy efficient heating systems available today. They’re also eco-friendly HVAC options because they don’t burn gas or oil,  and they use far less electricity than other systems. The main downside is that they can be expensive to install, but with significant rebates and tax incentives available, combined with the cost savings they offer over the years, it’s an increasingly popular option for homes to buy a heat pump.

“Two types of heat pumps are commonly used to electrify a home: Ground Source (geothermal or GeoExchange) Heat Pumps and Air Source Heat Pumps (ASHPs), says Larry Lessard, a respected authority in the field of geothermal energy. With Lessard as a guide, this post will help you decide if a geothermal system is right for you.

What Is a Geothermal Heat Pump?

How Does a Geothermal Heat Pump Work?

It works a little like a refrigerator, which removes heat from its interior and transfers it to your kitchen. A geothermal heat pump uses the same principle, but it transfers heat from the ground to your house (or vice versa). It does this through long loops of underground pipes filled with liquid (water or an antifreeze solution). The loops are hooked up to a geothermal heat pump in your home, which acts both as a furnace and an air conditioner.

During the heating season, the liquid pulls heat from the ground and delivers it to the geothermal heating and cooling unit and then to refrigerant coils, where the heat is distributed through a forced-air or hydronic system. During the cooling season, the process runs in reverse. The pump removes heat from your house and transfers it to the earth. Many units can provide domestic hot water as well.

Types of Geothermal Heat Pump Systems

The three closed-loop systems shown below are the most common. There is also a less common open-loop system that circulates surface water or water from a well through the system and returns it to the ground through a discharge pipe.

The best system, loop length and design for a particular home depend on factors such as climate, soil conditions, available land, required heating and cooling load, and local installation costs at the site.

Horizontal System

Layered coils or straight runs of polyethylene pipe are placed in six-foot-deep trenches. This is the cheapest underground option, but it requires a lot of open space. A 2,000-sq.-ft. house requires 400 ft. of two-foot-wide trenches.

Vertical System

A vertical system is used when space is limited. Four-inch-diameter holes are drilled about 15 ft. apart and 100 to 400 ft. deep. Two pipes are inserted and connected at the bottom.

Pond/Lake System

This system draws heat from water rather than from the soil. If there’s a body of water nearby, this is the lowest cost option. A blanket of water covers coils anchored on racks about 10 ft. deep.

How Much Does a Geothermal Heat Pump Cost?

The biggest downside to installing a geothermal heat pump is the cost. The system and installation can range from $10,000 to $40,000 depending on your soil conditions, plot size, system configuration, site accessibility and the amount of digging and drilling required.

For a typical 2,000-sq.-ft. home, a geothermal retrofit can cost up to $30,000. The system may require ductwork modifications along with extensive excavation. In a new home, installation costs would be on the lower end. Even so, a geothermal system will cost about 40 percent more than a traditional HVAC system.

Recouping these costs through energy savings could take as little as four years or as long as 15 years, depending on utility rates and the cost of installation. It takes some homework and professional estimates to figure out whether a geothermal system makes financial sense in your situation.

Tax Incentives and Rebates for Installing a Heat Pump

You can save some money on a geothermal heat pump system through tax credits. The Inflation Reduction Act of included a tax credit that can be worth as much as 30 percent of the cost for residential installations (and 30 percent for commercial buildings as well) for Energy Star qualified systems. Those tax rebates are available through .

There may be additional rebates available from your utility company as well as state and local governments, as well as incentives based on household income, so check with those entities if you’re considering installing a heat pump in a new home or retrofitting an existing house with one.

What Are the Benefits of a Geothermal Heat Pump?

“Ground source heat pumps are more than twice as efficient as air source heat pumps,” says Lessard. “They can replace existing ducted heating or cooling and support radiant flooring and domestic hot water. Even further, ground source heat pumps can be built out to support electric grids, buildings, and transportation.” Benefits include:

  • Much lower operating costs than other systems. A geothermal heat pump will immediately save you 30 to 60 percent on your heating and 20 to 50 percent on your cooling costs over conventional heating and cooling systems.
  • Uses clean, renewable energy. With a geothermal heat pump, there’s no onsite combustion and, therefore no emissions of carbon dioxide, carbon monoxide or other greenhouse gases. Nor are there any combustion-related safety or air quality issues inside the house. (The pump unit does use a small amount of electricity, and that may be generated using fossil fuels.)
  • Can be installed in new construction and retrofit situations. However, it’s a lot more expensive in retrofits requiring ductwork modifications.
  • Much quieter than other cooling systems. There’s no noisy outdoor compressor or fan. The indoor unit is generally as loud as a refrigerator.
  • Low maintenance and long-lived. The indoor components typically last about 25 years (compared with 15 to 20 years for a furnace or conventional AC unit) and more than 50 years for the ground loop. The system has fewer moving parts and is protected from outdoor elements, so it requires minimal maintenance.

What Are the Downsides of a Geothermal Heat Pump?

“The cost of installing a geothermal heat pump can sometimes be 40-50% more than a quality conventional system,” says Lessard. But, he says, installation costs can vary widely based on the geological condition of the land, and they could be even higher in some circumstances. “To evaluate cost, it is a good idea to get pricing from more than one reputable installer.” Besides high upfront costs, other drawbacks include:

  • Not a DIY project. Sizing, design and installation require professional expertise for the most efficient system.
  • Still relatively new. That means fewer installers and less competition. which is why prices remain high.
  • Installation is highly disruptive to the landscape. It may not even be possible on some lots. Heavy drilling or digging equipment will definitely crush your prize petunias.

Is Geothermal Right for You?

About 100,000 geothermal cooling and heat pumps are installed in the United States each year. According to Bob Donley, customer support manager at GeoSystems LLC in Minnesota, interest in geothermal HVAC is really on the rise.

A few factors to consider that could make your home a fit for a geothermal HVAC system:

  • You can stomach the upfront costs and plan to stay in your house for at least four to seven years (new construction) or 10 to 12 years (retrofit) to recoup initial costs through energy/cost savings.
  • You live on a large lot with a pond or a well. This would allow you to use a less expensive loop system (see Figure D).
  • You are building a new house and can roll the upfront costs right into the mortgage. You’ll be saving on heating and cooling costs on day one.
  • You have an existing house with high energy bills. This most likely means you currently use propane, oil or electricity for heating and geothermal cooling.
