2021 Best Outside AC Unit Covers

An AC unit cover is a protective layer for your outside air conditioning unit. This means it will help to protect the surface of your home from any damages that could arise from your A/C being present. It also prevents animals and insects from nesting in the crevices where you don’t want them to be.

It is a good idea to have a cover for your equipment as it will elevate the value of your home by protecting the investments you have made in keeping it cool and keeping heat out during those summer scorchers. Having an AC unit cover can also protect against tree branches, rodents, and debris that may damage the outside unit.

What Are the Benefits of Having an AC Unit Cover?

  • The prevention of mold and mildew in your home is caused by excessive humidity when the heat is running.
  • Protection from critters such as rodents, who can make a nest out of your outside A/C and also chew cords and possibly shorting them out.
  • It protects it from debris such as tree branches that may fall on top of the unit or wind may blow into it. This can cause damage to the sensitive parts that run it.

Will I Save Money With an AC Unit Cover?

Absolutely! It will save you money on your energy bills in the long run by preventing unnecessary heat from entering your home. Even though A/C units are designed to pull heat out of the air, they still use up extra energy when it has to work that much harder to do its job. By having an AC unit cover, you will see savings on your monthly bill because it will not be working as hard. Also, if water is able to get in between the coils and freeze; this can cause damage, which means costly repairs or replacements down the road for you. And if bugs or rodents make a home in your outside A/C they too can cause damage when they begin chewing through cords and shutting off circuits.

The energy savings from just the AC unit cover will pay for themselves over time, and there are other benefits as well. For example, if a rodent makes a home in the outside AC unit, it can chew its way through wires causing thousands of dollars worth of damage. There is also an added benefit of saving money on your pest control bills by preventing rodents from nesting in your A/C.

When Should I Use an AC Unit Cover?

  • You are expecting temperatures higher than 80 degrees overnight (Keeping your A/C off throughout the night may keep it from re-starting properly.)  -You are expecting temperatures lower than 20 degrees overnight (Keeping your A/C off throughout the night may cause it to freeze up.)
  • You are expecting temperatures higher than 90 degrees during the day. -You are expecting temperatures lower than 20 degrees during the day.
  • An unexpected heatwave is coming your way that you know would damage your A/C unit.

My AC has 2 hoses and 1 cable and are NOT in a tidy little bundle at the base of the unit. This cover deals with the issue very well.

After doing quite of bit of research/comparison of options & trying to determine the best replacement cover for winter for our AC unit, decided to go with this one. Am SO GLAD! Part of the reason we selected it was the close dimensions to our unit, but also the features described. Upon opening the package, was really impressed with the quality of the material (nice heavy duty canvas type w/solid stitching). That, combined with the perfect fit, the strong velcro on one side to fit around the tubing from unit to house, and the earth-tone duo-color design that compliments our house so well, believe we’re all set for the foreseeable future!

We bought an entire new HVAC system and this time I decided to protect the unit from leaves. So far so good. fits well, but since all A/C units are a bit different in size, make sure you get one that is not too snug. It might not fit. This one has a tug-string at the bottom that makes sure it will not come off. It also has a slit, for the copper pipe and wires to fit nicely.
