Fraser Valley HVAC & Sheet Metal, Built on Trust Since 1986
Big Valley Heating & Sheet Metal Ltd is a family-owned Fraser Valley HVAC and sheet-metal company, trusted since 1986. Honest advice, quality workmanship, and decades of community relationships.
It started in a Pitt Meadows garage in 1986.
Cousins Marlow Kirkwood & Ron McMyn founded Big Valley with a simple idea: give your neighbours honest, dependable heating and cooling — and treat every home like it belongs to family. Long days and careful workmanship built a reputation one customer at a time.
Nearly four decades later, we've grown into one of the Fraser Valley's most trusted HVAC companies — but we've never picked up a corporate mindset. You still get the same personal attention, straight answers, and neighbourly service we started with.
