Spring is here and so is the rain. Every year we get asked the same question. "Will the rain hurt my air conditioner?" We also get asked, "Should I cover my air conditioner during the off season?" The short answer to both questions is, "No!" Here's why:

Now for those of you who just can't stop thinking about the investment you had to make in your air conditioner, please don't go buy a tarp and wrap it up during the off seasons anyway. This can actually cause damage to your air conditioner by creating a damp environment for mildew to grow and mold to spread. These will attract all sorts of tiny creatures that will make your air conditioner their home. This includes getting a large black plastic bag to temporarily keep it safe or any type of plastic for that matter. Don't do it.
If you simply cannot help yourself and are losing sleep over it, then reach out to the manufacturer of your air conditioner. Some of them will sell you a custom covering that will protect your air conditioner in addition to keeping out moisture and other conditions that could be harmful. Unless you are an air conditioner expert, do not attempt to make your own "custom" cover. We know you're creative, but your air conditioner is unlike other household appliances and an expert is needed.
At the end of the day, just keep it simple. Leave your air conditioner uncovered. Check it regularly to clear away any debris that the wind may have blown against it. Get your spring tuneup annually and your air conditioner will last for years to come - even in the rainiest of seasons!
