Frequently Asked Questions
How much does HVAC service cost in Ottawa?
Cost varies widely between a routine furnace tune-up, a repair, and a full furnace or AC replacement. Ottawa's climate means both heating and cooling systems see heavy use, so get a written quote that breaks out labour, equipment, and any ductwork changes before committing.
How often should I service my furnace or AC?
Most HVAC pros recommend an annual furnace inspection before winter and an AC check before summer. Regular filter changes between visits also matter a lot for efficiency and equipment lifespan, especially given how hard Ottawa systems work through the winter.
Do HVAC technicians need to be certified?
Any work on gas-fired furnaces or gas fireplaces falls under the Technical Standards and Safety Authority (TSSA), which requires certified gas technicians. Ask to see certification before any gas-related work is done.
How do I find a reliable HVAC contractor in Ottawa?
Look for TSSA-certified technicians, strong recent reviews, and a written quote that specifies the exact equipment and work involved. Beware of anyone pressuring an immediate full-system replacement without first diagnosing the actual problem.
