Natural Resources Canada has created a set of resources on sizing and selecting air source heat pumps (ASHPs) in Canadian climates. These guides are designed to help contractors and mechanical system designers choose the right heat pumps for new homes or retrofit projects. The toolkit includes the ASHP Sizing and Selection Guide, an interactive Sizing and Selection Tool, and examples that show how to apply the process in real installation scenarios.

Homeowners interested in support with getting a heat pump that is sized correctly for their needs may be interested in our Heat Pump Right-sizing Service.
