Unit heaters are simple, tough workhorses — until they aren’t. If your garage or shop heater won’t ignite, keeps shutting off, smells off, or isn’t heating like it used to, it’s usually a safety or combustion issue that needs proper testing.
Peak Comfort HVAC provides unit heater repair across Ottawa and surrounding areas. We diagnose ignition and flame sensing, venting and draft, gas supply and pressure, safety limits, and electrical controls. We also check airflow through the unit and confirm it’s venting correctly for the space and setup.
These appliances are often installed in utility spaces where venting and clearances matter. Our goal is safe, reliable heat — with a fix that holds, not a temporary workaround.

• Safety-first diagnosis: We verify ignition sequence, flame stability, and proper safety shutdown: not just “get it running.”
• Venting and draft checks: Unit heaters live and die by venting. We confirm draft/pressure switch operation and venting condition.
• Proper gas and combustion approach: We confirm gas supply and operation instead of guessing at parts.
• Clear options: If a repair is reasonable, we repair it. If the unit is unsafe or not worth sinking money into, we’ll tell you straight.
• Clean, tidy work: Secure venting/drains (if applicable), tidy wiring, and a clean work area when we leave.
What to expect:
Step 1 — Diagnose: Confirm the failure with testing.
Step 2 — Explain & quote: Clear options and pricing before work starts.
Step 3 — Repair & verify: Repair, then verify safe operation and consistent heat output.
