Our story

A Cambridge HVAC business, kept in the family on purpose.

Howard Watson founded Watson Mechanical in 1989. In April 1994, his son Cory joined full-time. More than 30 yearslater, the same father-and-son team and a small bench of trained technicians still answer the phone, still walk the job, still spec the equipment that's right for the house.

We're a small company by design. That's what lets us call back the same day, finish the install the way we said we would, and stand behind the work for the long haul. The Biggest Small Company in Cambridge isn't a slogan, it's the operating model.

Brand partners

Two names that hold up where it counts.

We don't carry every brand on the truck. We carry the ones we'll service ten years from now. Luxaire for residential, Carrier for commercial. Other quality lines available where the project calls for it.

Luxaire HVAC brand mark

Luxaire, residential

Luxaire is the residential brand we install most. Heat recovery ventilation, air purification, humidification, and AC units that earn their keep through Ontario summers and winters. We're an authorized Luxaire dealer in Cambridge.

Carrier commercial HVAC brand mark

Carrier, commercial

For heavy-duty and light-capacity commercial use, Carrier is the name that businesses recognize for problem-free climate control. We pair Carrier with other quality brands so commercial customers get the right system at the right price.
