Recommendation for Scarborough and GTA
For most Toronto and Scarborough homes: cold-climate air-source heat pump is the practical choice. The installation cost is 4–8x less than geothermal, and modern cold-climate ASHPs close much of the performance gap. Ground-source is excellent for rural properties or large lots where ground loops can be installed economically.
Is air source or ground source heat pump better in Ontario?
For most Ontario urban and suburban homes (Toronto, Scarborough, GTA), an air-source cold-climate heat pump is the better choice: $5,000-$9,000 vs $20,000-$40,000+ for geothermal. Modern cold-climate ASHPs operate effectively to -25C. Ground-source offers higher efficiency but payback takes 20-30 years in urban settings.
