## Heating and cooling in Hamilton homes

Hamilton has one of the oldest housing stocks in the region. According to the 2021 Census, about 61% of homes were built before 1981 and 33% before 1961, and about 56% are single-detached.

- **Older homes in the Lower City (Durand, Kirkendall, Strathcona, the North End):** many still heat with [hot-water boilers](https://lancasterheatingandcooling.ca/heating/boilers/) or have limited ductwork. [Ductless heat pumps](https://lancasterheatingandcooling.ca/heat-pumps/ductless/) add efficient cooling and heating without major renovation.
- **Post-war and 1960s–70s homes on the Mountain:** original ductwork and chimney venting often need attention when the [furnace](https://lancasterheatingandcooling.ca/heating/furnace-replacement/) or [air conditioner](https://lancasterheatingandcooling.ca/cooling/ac-replacement/) is replaced.
- **Escarpment weather:** the Mountain is typically cooler, windier and snowier than the Lower City. Keep high-efficiency furnace vents clear of drifting snow; see our [furnace troubleshooting checklist](https://lancasterheatingandcooling.ca/furnace-not-working-checklist/).
- **Heating costs:** with long Hamilton winters, a high-efficiency furnace or a [hybrid heat pump system](https://lancasterheatingandcooling.ca/heat-pump-vs-furnace/) makes a real difference, and heat pumps qualify for [rebates](https://lancasterheatingandcooling.ca/rebates/).
