How to Prepare Your Furnace for Vancouver’s Coldest Months

As winter sets in, Vancouver homeowners rely heavily on their furnaces to keep their homes warm and comfortable. But cold snaps can be unpredictable, and a furnace that isn’t properly maintained may fail when you need it most. Preparing your furnace ahead of the season ensures your heating system runs efficiently, safely, and reliably all winter long.

1. Schedule Professional Furnace Maintenance

A professional HVAC technician can perform a thorough inspection and maintenance check before the coldest months hit. At Harbourgreene HVAC Services, we examine key components like burners, heat exchangers, and vents, ensuring everything is functioning optimally. Regular maintenance can prevent unexpected breakdowns and extend the life of your furnace.

2. Replace or Clean Furnace Filters

Dirty filters restrict airflow, forcing your furnace to work harder and reducing energy efficiency. Check your furnace filter every 1–3 months and replace it if necessary. For Vancouver homes that experience heavy winter use, replacing filters before the season begins is essential.

3. Inspect Vents and Ducts

Blocked or leaky vents can reduce the effectiveness of your heating system. Make sure all air vents are open and clear of obstructions, and consider having your ductwork inspected for leaks. Proper airflow ensures consistent warmth throughout your home while reducing energy costs.

4. Test Your Thermostat

A malfunctioning thermostat can lead to uneven heating or unnecessary energy use. Test your thermostat to make sure it accurately reflects the temperature and responds correctly. Upgrading to a programmable or smart thermostat can improve efficiency and give you better control over your home’s climate.

5. Check for Carbon Monoxide and Gas Leaks

Safety is critical during the winter months. Ensure your carbon monoxide detectors are functioning, and if you smell gas, leave the area immediately and contact a professional. Harbourgreene HVAC Services can inspect your furnace and gas lines to ensure your home is safe and secure.

6. Clear Outdoor Units and Combustion Vents

For furnaces with outdoor components, remove leaves, snow, and debris around vents and exhausts. This prevents blockages that can affect performance and reduce airflow. Keeping these areas clear is a simple yet effective step toward a smooth-running heating system.
