Winterizing an outdoor air conditioning unit helps keep it protected all season long, even from our brutal winters in Nazareth, Pennsylvania. If you’re looking to prep your air conditioner for the coming winter, here are a few tips we recommend.

Turn Off the AC Power

Before doing anything else to winterize your AC, locate your air conditioner’s power circuit outside and turn off the switch. This will prevent anyone from inadvertently turning on the air conditioner when you’re prepping it for winter, and it will prevent any costly damages.

Clean Off the Exterior Unit

Your exterior air conditioner unit is susceptible to dirt, pollen, leaves, grass, and other debris during the spring and summer seasons, so it can become quite dirty and clogged by fall. Be sure to inspect the exterior unit carefully and remove any debris buildup on the unit and the surrounding area. If you feel unsure about cleaning your unit, a professional can help inspect your unit for issues before it becomes a costly problem.

In addition to doing this basic cleaning, it’s also important to ensure there is a clear space 2 feet around the unit on all sides. If there are any plants or weeds growing near the unit, remove them or trim them back.

Cover the Unit with a Tarp

Once the exterior unit is completely dry and you’ve brushed off any remaining debris, cover the unit with a heavy tarp. Doing so will help keep out snow and ice this winter, which will prevent rust from forming inside the unit.

When covering the AC with a tarp, secure it tightly with bungee cords to prevent any strong winds from knocking the tarp off. Be absolutely certain the unit is not turned on with a tarp on it.

If you haven’t yet scheduled your annual HVAC maintenance, now would be the time to do so. Having your AC professionally maintained in the fall just before winterizing it will ensure it’s ready to go next spring. Your technician can also take a look at your furnace to ensure it’s ready when you turn on the heat.
