A Local Company. A Long Track Record.

Lambton Heating and Cooling was founded in 1969 with a simple goal: provide Sarnia and Lambton County homeowners with reliable, honest HVAC service from people who actually know the local climate. More than five decades later, that commitment hasn’t changed.

As a member of the ClimateCare cooperative, we combine the personal service of a local business with access to Ontario’s leading HVAC training, equipment, and support network. You get the best of both — a neighbour who knows your home and a team backed by the province’s most trusted HVAC cooperative.

We service all makes and models of furnaces, air conditioners, heat pumps, and water heaters. Whether it is a routine tune-up, an emergency repair on a January night, or a full system replacement, our certified technicians deliver the same standard of care every time.
