{Top 5} Best Air Conditioner Cover For Winter (in 2023)

When winters arrive, it is essential to take precautions to protect your air conditioning unit from harsh weather conditions. 

And as an air conditioning expert, I personally believe that the best way to protect your air conditioner during the coldest months is by investing in an air conditioner cover.

However, choosing the right cover for your AC is really a challenging task and it can take you hours to choose.

But to make this task easy for you. Our team evaluated a number of factors to provide you with the list of {Top 5} best AC cover for winter in the market.

Should You Cover Your Air Conditioner Outdoor Unit?

I am sure this question must have crossed your mind while buying an air conditioner, should I cover my AC unit? In fact, not just you but also many households have asked us this question many times.

Well, the answer is yes because the cover will prevent damage to the unit. The outdoor unit of an air conditioner consists of several important parts and components such as the compressor and condenser coil which are essential for the functioning of an AC.

These parts can be damaged by exposure to cold temperatures, snow and ice. A cover can help protect these parts by providing insulation from extreme temperatures and keeping debris out.

Not covering your air conditioning unit during the winter can lead to a number of problems that can cause significant damage to the unit, which will lead to major repairs and even replacement of the entire unit.

Covering an air conditioner during the winter is important to:

  • Prevent Moisture Damage: Moisture from snow, ice and rain can seep into the unit, which can cause damage such as rust and corrosion.
  • Avoid debris: Leaves, twigs, and other debris can clog the unit and damage the fan, motor, and other unit components.
  • Prevent pest infestation: Covering the unit helps prevent small animals and birds, such as rodents, from taking shelter inside the unit and damaging internal components.
  • Extend Lifespan: Exposure to harsh winter elements can cause premature aging and wear and tear, reducing the unit’s lifespan. Covering the unit during the off-season helps preserve it, and extends its lifespan.
  • Maintain efficiency: Failure to cover the unit during the winter can prevent proper airflow which will affect the efficiency of your unit and cause energy bills to rise. Covering it properly will prevent this problem.

There are many advantages to covering your AC unit during the winter, but unfortunately, there are also some disadvantages.

First, covering the unit can trap moisture, which can lead to mold and mildew growth and eventually damage the unit. Plus, covering the unit can provide a cozy home for rodents and other pests. And rodents and pests are an enemy to your AC unit that can cause significant damage to the unit’s electrical components.

How to Choose the Perfect Air Conditioner Cover for Winter?

In this section, we will see how to choose the right air conditioner cover for winter. Here are the four factors you need to consider.

1. Size and shape of the air conditioner

The first and foremost factor to consider when choosing an air conditioner cover is the size and shape of the unit. Air conditioner covers come in various shapes and sizes, some rectangular, some circular, so it is essential to choose the right one that fits the unit perfectly.

A cover that is too small will not provide adequate protection, while one that is too large will be cumbersome to install and may not offer a snug fit and will also provide hiding places for rodents and pests, which is harmful to both the unit and you.

2. Go with a waterproof cover

Going with a waterproof air conditioner cover is super important to protecting your unit during the winter months. The waterproof cover prevents rain, snow and ice from damaging the unit. 

The cover should be made of heavy-duty waterproof material, such as vinyl or polyester. Additionally, look for a cover that is UV resistant and able to withstand high temperatures.

3. Durability of Cover

When shopping for an air conditioner cover, it is important to make sure that you choose one that is durable and built to last. I don’t need to tell you that cheap covers are usually made of low-grade materials that don’t stand up to the wind, rain, and snow of the winter months. So look for a cover made of thick fabric or heavy-duty plastic, such as PVC or vinyl.

These materials are more resistant to wear and tear and will last longer. Otherwise, it may happen that you pull the cover and it bursts.

4. Look for the breathable cover

Breathable covers allow air to flow through the fabric while protecting your air conditioner from the elements. This helps prevent moisture from accumulating inside the unit and potentially causing damage. 

It also helps ensure that your air conditioner remains in good working order during the winter months. The most popular breathable materials for air conditioner covers include canvas and mesh fabric.

These are four main things you should keep in mind while buying an air conditioner cover for winter.

This COSFLY is one of the top air conditioner covers on the market. This waterproof and windproof cover is made from heavy-duty 600D polyester fabric, which is a plus point.

600D polyester usually refers to the type of polyester fabric used to make the product. The “d” stands for “denier,” a unit of measurement for the linear mass density of a fiber. The number “600” refers to the denier of the polyester fiber used in the fabric. 

Usually, a higher denier number means the fabric is thicker, stronger, and more durable that the lower denier number. 600D polyester is considered a medium-weight fabric and is used to make items such as backpacks, luggage, device cases, and outdoor gear. 

Furthermore, the cover comes with an adjustable click-close strap, these are designed to provide a secure and customizable fit for your cover, ensuring it stays in place.

Just like the Sugarhouse AC Cover, this one is also available in 11 different sizes, ranging from 24 x 24 x 26 inches to 38 x 38 x 40 inches.

For those looking for a reliable and stylish air conditioner cover for winters, the Covermates Air Conditioner Cover is a great option. This air conditioner cover is made from 300D stock-dyed polyester that is designed to last through even the harshest winter.

“Stock-dyed” refers to the process used to dye the fabric. With stock dyeing, the polyester fibers are dyed before they are woven into the fabric, to ensure that the color is deeply embedded in the material. 

This makes the fabric less likely to fade or lose its color over time, even with exposure to the sun. So this is a plus point as not all covers material that is dyed before being woven into fabric.

Furthermore, the cover comes with an elastic hem, which is designed to fit snugly around the edge of the cover, ensuring a tight fit around the AC unit. A tight fit is important to prevent the cover from slipping or shifting, which could expose the unit to the elements and allow rodents to get inside the cover.

Apart from this, it comes with mesh vents, these vents are designed to allow air to circulate around the covered AC unit and also prevent debris and dirt from entering the cover unit at the same time.

One great thing about this cover is that it comes in six different colors and 14 different sizes, giving you the freedom to choose the one you like. Another great thing is that it comes with a 3-year warranty, which is a testimony to the high quality of the product.
