Air-Source Heat Pumps

What Is an Air-Source Heat Pump? 

A heat pump is a complete replacement for your HVAC system—it can heat, cool, purify, and dehumidify your air.  An air source heat pump is comprised of two main components: an outdoor condensing unit (which often looks like a traditional air-conditioner) and an indoor air-handling unit or units. In the winter, a heat pump takes heat from outside your home and transfers it inside; in the summer, it reverses the process. 

Contrary to popular belief, air-source heat pumps work well in winter, even in our cold climate.  Below -15C, heat pumps can still heat your home with more than twice the efficiency of gas heating or standard electric heating (such as electric furnaces and baseboard heaters). They’ve been tested and approved as far north as the Arctic.  A supplementary heating system will be required for the coldest days of winter in our area.

Ducted or Ductless (Mini-Split) System?

Air-source heat pumps come in both ducted and ductless versions. Both systems use an outdoor condensing unit.  The difference is in the way they handle the air inside your home. 

Ducted heat pump systems use a single air-handling unit that redirects conditioned air throughout your home via ductwork.  The indoor unit is larger and often placed in a basement. 

Mini-Splits, or ductless heat pump systems, use small wall-mounted units (called mini-splits) to distribute and handle air. These are placed strategically throughout your home to ensure comfortable heating and cooling throughout different zones.

Benefits of Heat Pumps

  • All-in-one HVAC system: A heat pump can replace both cooling and heating systems, while also purifying and dehumidifying the air.
  • Comfortable: Because the heat pump circulates air continuously, your home will feel comfortable.  Depending on the number of indoor units, you can control the temperature in different areas of your home.
  • Safe: There is no combustion, flames or fumes and no chance of carbon-monoxide poisoning because natural gas, propane or oil are not required to operate the unit.
  • Flexible: As long as you have electricity, you can use a heat pump, even if you don’t have ductwork. 
  • Energy Efficient and Environmentally Friendly: Moving heat requires far less fuel than producing heat, making the heat pump very efficient.  Heat pumps can deliver more than 3 times the amount of heat energy for the amount of electricity they consume compared to traditional HVAC systems.  Heat pumps generate far less carbon dioxide than traditional heating methods.
