Tankless Water Heater Repair and Service in Ottawa

Tankless water heaters are great when they’re maintained and set up correctly — but when something is off, you’ll notice: error codes, temperature swings, low flow, ignition issues, or a unit that shuts down mid-use. Tankless problems can be mechanical, electrical, gas-supply related, or water-side (scaling and restriction).

 

Peak Comfort HVAC provides tankless water heater repair across Ottawa and surrounding areas. We diagnose venting, gas supply, ignition sequence, sensors, and performance under real demand — not just “does it turn on.” We also look for water-side issues that cause nuisance faults and inconsistent temperature.

 

You’ll get a clear explanation of what failed, why it’s happening, and what the proper fix looks like.
