Furnace & Water Heater Maintenance — Frequently Asked Questions

How often should I schedule HVAC maintenance in Ottawa ?

We recommend having your HVAC system serviced at least once a year ideally before winter for your furnace, with a check of your water heater at the same visit. Regular maintenance helps prevent breakdowns, improves efficiency, and increases the lifespan of your system.

What does a typical furnace tune-up include ?

A standard tune-up includes checking and cleaning the furnace burner, inspecting and replacing filters, testing safety controls, checking gas pressure, and verifying efficient airflow. We also test your thermostat, inspect venting, and ensure everything operates safely and reliably.
