Selecting the right heat pump is not just a matter of comfort, it’s an investment in your home’s sustainability and your family’s well-being.

Throughout this heat pump buying guide, we’ll walk you through the intricacies of heat pumps, from understanding how to choose the right type for your home, sizing it correctly, and maximizing its efficiency. 

Let’s begin the journey towards a more comfortable, sustainable, and cost-effective home heating and cooling solution!

Types of Heat Pumps

A heat pump is an alternative to traditional HVAC systems that offers numerous benefits to homeowners looking to heat and cool their homes. 

Heating-wise, heat pumps are different from furnaces and boilers because they only use a small amount of energy to move heat indoors. This two-in-one system also uses less energy to cool down households while generating almost zero gas emissions. They can help you decrease your carbon footprint and save money at the same time.  

Heat pumps vary based on what energy source they use for heat compression. Some common types are as follows: 

1. Air-Source Heat Pumps (ASHP)

This type of heat pump is the most common in Ontario households. Also referred to as air-to-air heat pumps, they work by extracting heat from the outside air and transferring it into your home during the heating season. In the summer, they can reverse the process to provide cooling. It can be ducted or ductless.

2. Ground-Source Heat Pumps (GSHP)

Ground-source heat pumps, also called geothermal heat pumps, are known for their renewable process. Instead of air, this heating system pulls heat from the earth, groundwater, or both to warm the coils or underfloor heating. They are highly efficient and environmentally friendly.

3. Water-Source Heat Pumps (WSHP)

Water-source heat pumps use the same principle as air-to-air heat pumps, but transfer heat to a hydronic heating system (radiant floor heating or baseboard radiators) or for domestic hot water heating.

4. Hybrid Heat Pumps: Combining Technologies for Efficiency

Hybrid heat pumps, also known as dual-fuel furnaces, consist of an electric heat pump and a gas furnace. You get the best of both worlds with these.

Choosing the Right Heat Pump for Your Home

You should consider several factors when buying a heat pump, including the region you live and the size of your home.

Assessing Your Climate and Region

While all heat pumps provide ample heating and cooling, not all models can withstand extreme temperatures, especially during winter.

The Northeast Energy Efficiency Partnerships (NEEP) has released a database of various heat pump models that can withstand the winter cold. You’ll find multiple models with varying ranges in temperature limits, making them perfect for below-zero climates. 

Additionally, you should look for a variable-speed compressor in heat pumps. This component helps the system switch and adapt to changing temperatures, which is especially beneficial for homeowners living in regions with varying climates.

Sizing Your Heat Pump

Many sizes are available on the market, but unfortunately not all will fit your heating and cooling needs. Oversizing leads to a waste of resources, while undersizing puts too much stress on the pump. Factors to consider include: 

• Your home’s layout
• Number and location of windows
• Home insulation
• SEER Rating
• Flow Rates

Calculating Heat Load and Heat Loss

You can get the correct heat pump size by calculating the heat load and loss. 

The rule of thumb for heat load is that 1 sq. ft. of living space equals 30 BTU heating output. Measure your home’s total square feet, then multiply it by 30. 

Heat loss calculations use more complex formulas. It involves measuring various areas of your home and using a program to find out the heat loss of each room. An HVAC professional will be able to do these calculations for you.

Professional Installation and Maintenance

The effectiveness and longevity of your heat pump depend not only on selecting the right system but also on proper installation and ongoing maintenance. 

Installing a heat pump is a complex task that requires technical expertise. It’s crucial to hire a licensed and experienced HVAC contractor for the job. Here’s why professional installation is essential:

• Ensures the correct sizing and placement of the heat pump for optimal performance
• Guarantees the proper installation of refrigerant lines and electrical connections

Heat Pump Installation Process

• Site Assessment: The contractor will assess your home to determine the best location for the heat pump’s outdoor and indoor units. Factors such as sun exposure, airflow, and proximity to existing infrastructure are considered.
• Proper Sizing: Based on your heating and cooling needs, the contractor will ensure the heat pump is appropriately sized. This step is crucial for efficiency and comfort.
• Quality Installation: A professional installation includes properly sealing and insulating ducts (if applicable), ensuring a level and stable foundation for the outdoor unit, correctly connecting refrigerant lines and electrical wiring, and testing the system thoroughly to verify performance.

Post-Installation Checks

• System Testing: After installation, the contractor should perform comprehensive tests to ensure the heat pump is functioning correctly. This includes checking for refrigerant leaks, airflow, and thermostat calibration.
• User Training: The installer should provide you with instructions on how to operate and maintain your heat pump efficiently. This includes setting temperature controls, changing filters, and understanding the thermostat.

Heat Pump Maintenance for Prolonged Lifespan

Proper installation and routine maintenance not only extend the lifespan of your heat pump but also maintain its efficiency, which translates into lower energy bills and a more comfortable home. By staying proactive, you’ll ensure that your heat pump continues to serve your home reliably for years to come.

Small actions—like replacing the air filter, dusting the vents, and keeping the outdoor unit clean—can make a big difference in the health of your heat pump.
