For prompt, reliable, professional, and trustworthy HVAC service in Ancaster, look no further than Lancaster Heating and Cooling.

Heating and cooling in Ancaster homes

Ancaster mixes some of Hamilton’s oldest homes with some of its newest. Heritage buildings along Wilson Street date back to the late 1700s, while most growth since the 1960s has been east of Highway 403. According to the 2021 Census, about 75% of homes in Ancaster are single-detached, and roughly 33% were built in 2006 or later.

  • Newer subdivisions (Meadowlands and east of the 403): many furnaces and air conditioners installed in the 2000s are now 15–20 years old. A hybrid heat pump system is worth considering when it’s time to replace.
  • Ancaster Village and heritage homes: older homes often have limited duct space. Ductless heat pumps and custom ductwork add comfort without major renovation.
  • Rural Ancaster: we install and service propane furnaces and convert appliances between propane and natural gas. See gas line services.

Lancaster Heating & Cooling never disappoints! Our family has been dealing with them for a number of years and every experience is a WOW moment! My AC stopped working last night and of course I called Lancaster. Today it is working again – thanks to Rob, who has done an excellent job every time when I need something, whether it is diagnosing, fixing or installing a new AC or furnace. This is THE COMPANY you can trust for all your heating and cooling needs! Thank you again Lancaster for your great service and customer experience!
