“With a newborn at home, a cold house was not an option. They answered immediately, squeezed us in that evening, and the heat came back on before bedtime. So grateful.”

Expert Gas & Electric Fireplace Installation
St Thomas Heating & Cooling: Building new or opening up a wall in an older St. Thomas home? We design fireplace installations around your layout, running gas lines, sorting direct-vent or chimney routing, and finishing so the unit looks built in, not bolted on. Replacements and upgrades handled too.
Why Homeowners Call Us
Basement or addition too cold, and baseboards are not fixing it?
A direct-vent gas fireplace or sealed insert can turn that cold room into the warmest one in the house, efficiently and safely.
Quick Diagnosis for Existing Fireplaces
Pilot will not stay lit, burner weak, fan noisy? We diagnose thermocouples, valves, and venting on gas units fast, and tell you honestly whether a repair or a replacement wins.
Winter-Ready Fireplaces, Checked Before the Cold
Book a pre-season check and we inspect the pilot assembly, thermocouple, and venting before the first hard freeze arrives. Ten minutes of prevention beats a cold living room in January.
Family-Run, Licensed, and Fully Insured
As a family-run HVAC company, we install fireplaces with transparent pricing, tidy workmanship, and the kind of accountability that comes from a local crew working in its own community, every single job.
FAQ
Fireplace Installation in St. Thomas: Common Questions
How much does fireplace installation cost in Ontario?
Fuel choice moves the number more than brand does. Electric units need only a circuit, gas needs a certified line and vent, and wood needs chimney work. Quotes are free.
How long does a fireplace installation take?
Quick answer, a day for most units. Long answer, gas line upgrades, chimney liners, and custom stone surrounds each add their own steps, so we map the timeline before starting.
Should I repair my old fireplace or replace it?
Age and efficiency decide it. A sound unit with a fixable fault deserves repair, an aging fireplace leaking heat up the chimney does not. We tell you which yours is.

“Our cold-climate heat pump struggled in a deep freeze, so I called in the morning. A tech arrived that afternoon, found a frozen sensor, and fixed it on the spot.”
