Options To Seal A Window Air Conditioner For The Winter

Window air conditioners can be winterized in one of two methods. The second, on the other hand, could be a headache because it will take time and winter will arrive sooner rather than later.

The only method to keep the heat in your home without having to remove your appliance is to seal it to the window. That is, if you’re having a hard time getting the unit out of the window fully.

When it comes to air conditioners, weatherizing them will also help them live longer by protecting them from the weather’s detrimental impacts. Now let’s get to the meat of the matter: how will we go about doing this, and how can we be sure it’s a good idea?

We’ll get it done in no time with just a little bit of work, and we’ll be done in no time at all. This will ensure the safety of your air conditioner and keep you comfortable during the winter. With that in mind, here are a few things you can do to get ready for what’s to come. Consider saving for the future as well.

Option #1. Using foam insulations around the appliance

Having the appliance positioned near a window means that you may be exposed to the cold air of winter without even realizing it. We’re crossing our fingers that you’ve saved up enough money to cover the cost of foam insulation for this phase. Make sure you buy enough so that you can take accurate measurements of all the spaces that will be insulated with foam.

As a last step, cut strips of firm foam insulation to fill the spaces between the window frame and your air conditioner. Make certain that the foam insulation is snugly put so that air from the outside is likely to be fended off.

If you’re planning to use this method but don’t know where to find the low-cost materials you’ll need, you can check out this website. Spray foam insulation can be used if no other types of insulation foams are accessible in your area; nevertheless, you must exercise caution when utilizing it due of its huge expansion.

Option #2. Covering your AC unit with heavy fabric

Hardware stores, as we all know, sell appliances and building materials, right? That being the case, another alternative is to get an air conditioner cover. It will cost you money, so be prepared for that. Even if they’re hard to come by in some places, some are built specifically for your appliances.

Even while you may buy one online, going to a local store is preferable, especially now that winter is just around the corner. Afterwards, you’ll need to slide the AC cover right off the appliance’s exterior so that it can withstand the changing seasons. You can use it to keep your air conditioner warm in the winter.

Option #3. Weatherizing

For this procedure, all you need is a plastic bag and some tape. In order to do this, you’ll first need to remove the appliance’s exterior cover. To keep it sealed, put a plastic bag inside the container and cover all exposed areas.

Afterwards, you’ll take your duct tape and secure it in the bag so that it doesn’t move around while it does its job. In order to prevent damage to the components within from severe temperatures, make sure all pieces are tucked into the bag. Once you’ve finished, reattach the cover.

How to Seal a Window Air Conditioner for the Winter? Steps by Steps

Preparing your window air conditioner for winter is critical. That’s why we’ve laid out the method in these step-by-step instructions so that you may carry out the task on your own. Before it gets too chilly, you should get started. Each step of the procedure lays out exactly what you need, how long it will take, and what you can expect to pay.

You may have initially considered removing the entire device. If possible, store your AC somewhere safe and protected so that you can quickly reinstall it if you need it. For those who can’t, these instructions will help you protect and seal your unit.

1. Turn It Off

To turn off your air conditioner, locate the switch on the panel and flip it to the “off” position. Also, make sure it’s unplugged. This prevents the unit from turning on if it’s a little warmer outside, which could cause issues when it gets cold outside again. They also provide reassurance that working on the apparatus will be safe for the time being.

2. Clean The Unit

Additionally, it’s an essential step in order to avoid damage in the winter months by cleaning your AC after a long hot summer. You’ll need a screwdriver, a sponge, a brush, and soapy water to open the device.

Using a brush and sponge and a tiny bit of water, carefully clean the device to remove any dirt or debris. To prevent the growth of mold and mildew, use the dry towel to clean the surfaces and remove any extra moisture.

You may want to use a vacuum cleaner or a gentle dusting to clean the inside sections. It may take some effort, but it’s worth it to keep your air conditioner in good operating order.

3. Measure Up

After the device has dried, the insulation can be applied. There are a few tools you’ll need for this project: a pencil, a utility knife, and a measuring tape to cut through the insulating foam.

First, measure the distance between your unit and your windows to get a sense of how much foam you’ll need. As a rule of thumb, the tighter the fit, the better the insulation, so do this first. When cutting foam, it’s advisable to cut it overly large and then trim it down later if necessary.

4. Add Insulation

Make a mark on the foam with your measurements and then cut it to fit. Foam should be stuffed into any and all cracks and crevices between the window and the unit. Plastic sheeting or tarpaulin and duct tape can be used to finish the job, as can removable sealant and a caulking gun.

It’s possible to secure the foam by taping the edges of the cover. Apply a removable sealer on top of the foam to keep it in place. You can now use duct tape to tie an additional layer, such as a tarp, around the entire device. Adds insulation and protects your air conditioner from the weather.

For this procedure, you’ll only need one person to accomplish it. Take your time to ensure that each piece of foam is securely fastened to the board.

5. Check Your Unit

Make sure the cover is still in place, that the snow hasn’t made its way into any holes, and that you’ve secured the unit in the event of a very cold or stormy weather. You can keep the device safe by removing snow, adding extra duct tape, or adjusting the covering.

Other Air Conditioner Insulation Tips, Tricks, and Hacks for Winter

Reading these tips and tricks before following the steps listed above could save you a lot of time in the long run.

Can You Remove Your AC?

Even if you believe your unit must remain in the window throughout the year, it’s worth double-checking to see if it is removable. If you’re able to move your air conditioner, you’ll be able to do so routinely and safely store it. As a result, your heating cost will be less expensive as a result of this simple approach.

Does Your Unit Have a Cover?

Many air conditioners are shipped with a cover that was custom-made for that particular model by the manufacturer. Since it’s already shielded from the weather, you won’t need to cover it with a tarpaulin. Plastic sheeting can be used as a substitute for a cover if you don’t have one.

Use The Right Insulation

In the event that you use a sealant, check the packaging to see if it specifies it can be removed, as you will need to do so. The use of spray foam as an insulator should be approached with caution. It has a large range of expansion, making it difficult to quantify accurately. Foam sheets that are just over an inch thick give the correct seal, but if you live in a particularly cold area, you might prefer slightly thicker material.


Turn off your AC unit, clean it, measure your foam, and then fix the insulation using duct tape or a cover in order to keep it in place. In order to keep your air conditioner in good working order and keep your home from losing heat, you need to follow these measures.
