As temperatures drop and the Okanagan shifts into winter mode, most homeowners turn their attention from cooling to heating — but your air conditioner deserves a little attention before it rests for the season. Properly winterizing your outdoor AC unit helps protect it from damage, extend its lifespan, and ensure it’s ready to perform next spring.
Here are five simple steps to get your system winter-ready:
1️⃣ Shut Off Power
Before anything else, switch off the power to your outdoor unit using the disconnect box, usually located beside the condenser.
Turning off the power ensures the system won’t accidentally start up on an unusually warm day, which can cause water to freeze inside the coils and lead to damage. It’s a quick but crucial first step in protecting your investment.
2️⃣ Clean the Area
Once the unit is powered down, give it a good cleaning. Remove leaves, twigs, dirt, and debris that may have collected around the base or inside the fins.
This helps prevent rust, clogs, and pest nesting over the winter. You can gently hose down the exterior if it’s especially dirty—just make sure it’s fully dry before covering. A clean unit is a happy unit come springtime!
3️⃣ Cover the Unit
While it might be tempting to fully wrap your AC for winter, less is often more. Use a breathable, waterproof cover or just cover the top to protect it from snow, ice, and falling debris while allowing airflow.
Completely sealing the unit can trap moisture and cause rust or mold growth inside. If you live in an area with heavy snowfall, you can also place a piece of plywood on top to add an extra layer of protection.
4️⃣ Adjust Thermostat Settings
Now that cooling season is officially over, switch your thermostat from cooling to heating mode. Set your preferred temperature schedule to balance comfort and energy efficiency.
If you use a smart thermostat, take a few minutes to review your routines and update them for your winter schedule. Small adjustments can make a big difference in both comfort and energy savings.
5️⃣ Book a Fall Tune-Up
Before winter settles in, it’s the perfect time to have your furnace or heat pump serviced by a certified technician.
A fall tune-up ensures your heating system runs safely and efficiently all season long — and gives your AC a professional once-over before it goes dormant. This small step helps prevent mid-winter breakdowns and keeps your HVAC system running smoothly year-round.
A Little Prep Goes a Long Way
Winterizing your air conditioner doesn’t take long, but it pays off in reliability and longevity. By shutting down, cleaning, covering, adjusting, and scheduling a quick tune-up, you’re protecting one of your home’s biggest comfort investments.
