It's Winter - What Are You Going to Do With Your Air Conditioner?

Even though it’s now winter, don’t neglect your air conditioner! Your air conditioner has been working hard all summer by moving air across its refrigerated coils to provide cooling comfort to your home, and by performing a few simple winterizing tasks, you can improve your air conditioner’s energy efficiency and extend its lifespan.

For Central Air Conditioners:
1. Begin by cleaning the condensing unit of debris by spraying the fan blades and condensing coils with a high-pressure hose.

2. Cover the condensing unit with some kind of breathable, waterproof cover designed for this purpose. If left exposed to the winter elements, the condensing unit can become damaged by debris and wet leaves, which can then lead to rusting and freezing of the internal components.

For Room Air Conditioners:
1. Storing your air conditioner in the winter protects it from the elements and also makes it easier to clean. Remove your air conditioner from the window mounting or wall and store it indoors. If the unit is hard to remove, you may have to alter the mounting bracket.

2. To stop drafts, seal the window opening or wall. If the unit is mounted in a window frame, close it and latch the window. However, if it’s mounted in the wall, cut a piece of plywood to fit over the opening and screw it in place. Create a thermal barrier by adding a piece of foam insulation, and make sure that snow and rain can’t collect.

3. Clean your air conditioner by removing both the inside and outside grills. Use warm water and a brush to remove any accumulated debris or dirt from the coils and fan, as debris often slows air movement and inhibits heat transfer between the surrounding air and coils.

4. If the air conditioner cannot be removed, at least try to clean it in place and purchase some kind of cover to protect it from the weather and to prevent winter drafts.
