Heat Pumps: Heating and Cooling Wrapped in One
Enter your location
Heat pump technology has been around since the mid-1800s, but they’re more commonly used in Europe and the southern United States.
Heat pumps work using a very simple principle of thermodynamics: Make a region colder than another and heat energy will always flow into the colder area.
This is the principle under which the majority of air conditioners work—whether freestanding units, forced air, or otherwise. Yet, traditional air conditioners generally only move heat in one direction—out. In contrast, heat pumps can effectively pump heat both out and in. This means that during the summer months, any standard heat pump can operate like a traditional air conditioner—cooling the home by removing heat and releasing it outside. Then, during cooler months, you can reverse the heat pump’s process, to extract heat from the air outside of your home and pull it inside in order to increase the temperature in your dwelling.
This process works effectively in moderately cold weather – think Canadian autumn and spring. However, once the outside temperature drops below a certain threshold, heat pumps won’t work as efficiently—they can develop a thick layer of frost on their condenser coils, which slows the process of pulling heat from the outside air and can also impede airflow. At a certain point, if you’ve got a furnace as a heating back-up with the appropriate controls, your furnace will likely kick in and take over heating your home.

Here in Canada, many of us deal with below-zero temperatures for at least part of the year. If you’re looking for an alternative heating and cooling source but live in an especially cold climate—particularly if the outdoor temperature drops below -15°C for long stretches of time—consider a geothermal system.
Unlike traditional models that pull heat from the air, geothermal systems take advantage of the consistent temperature of the earth, moving heat from the ground into the home during cold winter months and removing the heat from the home and back into the earth in the summer.
