Shutting down an air conditioner doesn’t just entail flipping a switch. You’ll need to take several steps to protect your system from damage over the winter. Here’s a handy guide to shutting down AC components when the temperatures start to drop.
Get Repairs Done
The first thing you need to do is check the condition of the indoor and outdoor units of your air conditioner. Make sure they’re in good condition and don’t require any repairs. If repairs are needed, be sure to contact an HVAC contractor. Also, ensure that their seals are tight and that their filters are clean. Preexisting issues will get worse if you leave them unattended through the winter.
Disconnect the Condenser’s Power
You have to shut off the condenser outside to prevent it from turning on when there’s a warm spell in the winter. If it turns on, it can get damaged after sucking in ice and snow. To disconnect the power, shut off the unit’s breaker switch. It’s usually on the side of the house or under a flip-up lid close to the condenser.
Clean the Condenser
Once the condenser unit has no power, it’s safe to clean it. Start by sweeping away debris such as branches and leaves that are on or near the unit. Next, hose down the exterior cabinet lightly. As the condenser dries, inspect it once more for loose seals or damage. If you spot anything irregular, inform a professional the next time you’re working with one.
Cover It Up
Once the condenser is dry, cover the unit with a waterproof cover. Secure the cover with bungee ropes. You can find the ropes and cover at local hardware stores.
