Considering the snow and ice we get in the Dayton area over the winter, you might not be too surprised when you end up with a frozen A/C unit. That doesn’t mean that layer of ice is something you can ignore, though. Ice on your outdoor condenser unit can damage the fins and internal components. To protect your A/C unit, take time for a little winterization.
Give Your Unit Some Shelter
If you leave your outdoor condenser unit exposed to freezing rain, snow, and wind, chances are high it will freeze over. By covering the unit, you’ll reduce the moisture inside and break up chilling winds, reducing the risk of ice formation. For optimal protection, invest in an air conditioner cover made of canvas, polyester mesh or another material that breathes. Never use a tarp or other plastic cover. Plastic holds in moisture, making ice formation more likely.
For extra protection from rain and snow, lay a square of plywood over the unit. Place a heavy object, such as a brick, on each corner to hold the wood down.
If your condenser is under the roof eaves, melting snow dripping onto the unit can encourage ice buildup inside. Periodically check the unit for internal ice buildup even if you don’t see much ice on the outside.
Use Your A/C Wisely
While it’s safe to run your air conditioner in the late fall and early spring, avoid turning it on when temperatures are expected to fall below 62 degrees and don’t leave it on overnight. Cool outdoor temperatures are more likely to cause a frozen A/C unit. For milder days, ceiling fans are a more energy-efficient cooling option.
If you’re concerned about a thick layer of ice on your outdoor unit, contact an HVAC technician. Never try to remove the ice by hand or by using a sharp object. Besides the risk of injury, you could also permanently damage your air conditioner.
