How do I prepare my HVAC for winter in Ottawa?

Start preparing your HVAC system for Ottawa's harsh winters in early fall - ideally by October - to ensure reliable heating when temperatures drop below -20°C. The key steps include furnace maintenance, filter changes, and system testing before you actually need the heat.

Schedule a professional furnace tune-up with a licensed HVAC technician before the heating season begins. This service typically costs $150-$200 in Ottawa and includes cleaning the heat exchanger, checking gas connections, testing safety controls, and ensuring proper combustion. Your technician will also inspect the venting system and test for carbon monoxide leaks - critical safety checks that only qualified professionals should perform.

Change your furnace filter and stock up on replacements for the winter months. Ottawa's dusty conditions during construction season and winter heating cycles mean filters need changing every 1-3 months. A clean filter improves efficiency and prevents your system from overworking during those long Canadian winter nights when your furnace runs continuously.

Test your heating system early by running it for several hours on a cool fall day. Listen for unusual sounds, check that all vents are blowing warm air, and ensure your thermostat is responding properly. Clear any debris from around your outdoor heat pump (if you have one) and ensure vents and intakes aren't blocked by leaves or other obstructions.

Ottawa's extreme winter temperatures put extra strain on HVAC systems, making preventive maintenance essential. Carbon monoxide detectors should have fresh batteries, and you should know the signs of CO poisoning - headaches, dizziness, or flu-like symptoms that improve when you leave the house.

If your furnace is over 15 years old or you've noticed higher energy bills, consider having a professional assess whether a high-efficiency upgrade would save money over Ottawa's long heating season.
