Vancouver Island winter is not Alberta winter. We don’t fight cold, we fight damp, wind, salt, and the surprise cold snap that turns up two or three times a season and catches everyone off-guard. The prep list is different from what a homeowner in the interior would run.
Here’s what to do before the rain and wind really settle in — HVAC, electrical, and plumbing — with the Island-specific items most generic checklists miss.
HVAC and heating
Book your annual heat pump maintenance visit — before the season, not during it. The right time is late September to early November. Not January when the system starts complaining. A proper maintenance visit takes 60–90 minutes and covers refrigerant charge, coil condition, drain lines, filters, and operational testing. If your last “annual maintenance” was 20 minutes and a signed invoice, you got the filter changed and a sticker. Our full checklist of what a real visit includes is here.
Coil rinse if you’re within a kilometre of the water. Salt air accumulates on outdoor coils and eats aluminum fins over time. Anywhere from Whiffin Spit to East Sooke, oceanfront Metchosin, Cordova Bay, Departure Bay — the coil needs a proper rinse before winter, not just a garden hose spray.
Check your backup heat plan. If you have a heat pump plus baseboards or an electric strip, verify the backup fires when called. Nanaimo and the mid-Island use backup heat a few nights a year on the coldest Arctic outflow. If you haven’t tested the backup since spring, you don’t actually know it works.
Clear the area around your outdoor unit. Cedar needles, fallen leaves, spider webs, moss. The unit needs airflow. If moss has grown over the top or fan blades in the shoulder season, sweep it off before it packs down in wet weather.
Furnace users — get the ignition and heat exchanger checked. Gas furnaces have specific safety inspections that matter. If you smell any exhaust odour inside the house when the furnace runs, don’t wait — that’s a call this week, not next month.
Electrical
Test your GFCIs and breakers. Push the “TEST” button on every GFCI outlet in the house (bathrooms, kitchen, outdoor, garage). If it doesn’t trip, it’s failed and needs replacement. Same for the arc-fault breakers in newer panels.
Look at your outdoor outlets and cords. Outdoor GFCI outlets take a beating from Island winter. Cracked covers, water intrusion, corroded plugs — all need attention before the wet season really hits.
If you’re planning holiday lights, plan the load. A single decorative circuit can handle a lot of modern LED lights, but if you’re running heaters, hot-tub circuits, and holiday lighting from the same panel, you might trip breakers on cold evenings. Older 100-amp panels feel this most. Our panel upgrade guide covers when the load is genuinely stretched vs. when a contractor is trying to upsell you.
Check the generator (if you have one). Wind knocks out power on the Island. Not often, but a couple of times most winters. If you have a standby generator, run it through a test cycle before December. If you have a portable, verify it starts, has fuel, and the transfer setup is safe.
Plumbing
Disconnect and drain outdoor hoses and hose bibs. Even on the Island where hard freezes are rare, one −5°C night is enough to burst an exterior line if a hose is holding water against the shut-off valve.
Insulate exposed pipes in crawlspaces and unheated garages. The Island’s winter damp does more damage than the cold — moisture accumulates around exposed lines and corrodes fittings. Foam pipe insulation is $10 a roll at a hardware store and takes an afternoon.
Perimeter drains — this is the big one. Foundation perimeter drains (the black pipe around the base of your house that carries roof and grade water away from the foundation) fail slowly. Roots grow in, silt fills them, sections collapse. You don’t notice until water is pooling against the foundation or backing up into a basement or crawlspace during a heavy rain event. If you’ve had water intrusion, sump pump cycling more than usual, or unexplained damp in a crawlspace, it’s a perimeter drain conversation. Our sister plumbing brand, Under The Seat Plumbing (UTS), digs perimeter drains — more on that here.
Check the sump pump. If you have one, pour a few gallons of water into the pit and confirm it kicks on. Sump pumps that sat idle all summer sometimes seize. Better to find out in October than during the first November atmospheric river.
Water heater flush. If you haven’t flushed sediment from the tank in a couple of years, do it now. Sediment reduces efficiency and shortens the tank’s life. Applies to conventional and hybrid tanks; skip for tankless.
The Island-specific items most checklists miss
- Moss removal from roofs. Not our trade, but flag it — moss holds moisture against shingles and shortens their life dramatically.
- Gutter cleaning before the second big rain event. First rain of fall clears loose debris; the gutters need to be clean before that or the water goes into the foundation instead of the downspouts.
- Cover for the heat pump outdoor unit — DON’T. Common mistake. Full covers trap moisture and cause worse corrosion than the weather does. A partial snow-shield on top is fine. A wraparound cover is not.
What to expect from us
Our Comfort Specialists come to your home for a written quote before any work happens. Annual maintenance visits are pre-booked on a schedule that catches you in the right season. If a full assessment turns up a real problem (a failing heat pump, a stretched panel, a compromised perimeter drain), we quote the fix separately.
