Don’t Get Caught in the Cold: How to Winterize Your Greater Victoria Heat Pump

Most homeowners in Greater Victoria love heat pumps because they provide comfortable, energy-efficient air conditioning during our increasingly hot summers. But as the damp, chilly Vancouver Island winter approaches, your system has to flip its job completely.

While our winters are mild compared to the rest of Canada, our unique mix of high humidity, freezing rain, and sudden windstorms can be brutal on an outdoor HVAC unit. Taking a few minutes to prepare your system now will save you money on your hydro bill and prevent emergency calls when the temperature drops.

Here is the ultimate guide to getting your heat pump winter-ready.

1. Clear a 2-Foot Safety Zone Around the Outdoor Unit

Your heat pump needs to breathe to pull heat out of the outdoor air. If the airflow is blocked, the system has to work twice as hard, sky-rocketing your electricity bill.

Trim the bushes: Cut back any overhanging branches, hedges, or dead summer plants. Keep a clear two-foot space all around the metal cabinet.
Watch for falling leaves: Autumn winds drop wet, heavy leaves that stick to the sides of your outdoor unit. Brush these off regularly so they don’t clog the vents.

2. Elevate and Protect from Snow and Ice

We don’t get regular blizzards in Oak Bay or Langford, but when it does snow, it tends to be wet and heavy.

Check the base: Ensure your outdoor unit sits on a raised stand or concrete pad. It needs to be kept clear of pooling water and minor snow accumulation.
Never build a tight roof: Do not cover the top of your heat pump with a tarp or a low wooden lean-to. Heat pumps exhaust air straight out of the top. Blocking this will trap the air and cause the system to fail.

3. Change Your Indoor Air Filters

A dirty indoor filter restricts air from moving through your home. This forces the system to run longer cycles, adding unnecessary wear and tear to its parts.

Inspect monthly: Check your furnace or air handler filter every 30 to 90 days.
Swap it out: If the filter looks grey or is covered in pet hair and dust, replace it immediately. Clean filters keep your indoor air fresh and keep your heating bills low.

4. Understand the "Defrost Mode" Myth

New heat pump owners often panic during their first winter when they see steam rising from the outdoor unit or hear it making a loud buzzing noise.

Don’t worry, it’s normal: This is just the system’s automatic defrost cycle. Because Victoria air is highly humid, ice naturally builds up on the outdoor coils.
How it works: The system temporarily reverses itself to melt the ice away. It may look like smoke, but it is just harmless steam!

5. Schedule a Professional Winter Tune-Up

While DIY cleaning helps, some tasks require a certified professional. A seasonal inspection by a technician ensures your system won’t quit on you during the coldest night of the year.

A professional RedBlue HVAC Maintenance Visit includes:

Checking refrigerant levels and testing for hidden leaks.
Inspecting and tightening electrical connections.
Testing the auxiliary backup heat strips to ensure they activate properly.
Cleaning the deep internal coils that regular tools can’t reach.
