Heating & Gas Line FAQ

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.

How much does a water heater replacement cost in Ottawa ?

Pricing depends on the size and type of your water heater (tank, power-vent or tankless), the venting and the gas or electrical work needed. Contact us for a custom quote for your home.

What are the common signs that my HVAC system needs repair ?

Some red flags we see often in Ottawa homes include unusual noises (like banging or rattling), rising energy bills, weak airflow, frequent cycling on and off, or your system not keeping your home at the right temperature. If you notice any of these, call us for an inspection.
