Heat pumps are efficient, affordable, and ideal for condo life and other smaller homes in Toronto and the GTA. Where they tend to lose a bit of steam though is if you live in a bigger home with many people. If you have a bigger family in one home, you may notice that you’ll need more than 1, or event 2 heat pumps installed in order to keep everyone happy in the winter. After all, the bigger the family, the less likely you’ll all want to spend all your time in the same areas of the house.
