The Best Foam Tape for Window AC Units

Summer is here! It is time to invest in a new air conditioner if you want to stay cool, but if you already have a window unit, you can stay comfortable without making a big purchase. One important thing to keep in mind is replacing your window units weather seals. Not only will doing so reduce your energy costs by preventing hot air from seeping into the room, but it will also help prolong your air conditioners lifespan.

With that in mind, lets take a closer look at the importance of replacing window unit air conditioner weather seals and how you can do it.

Window unit air conditioners rely on weather seals to keep cool air inside your home and keep hot air outside. The seals also help keep out dust, debris, and pests like bugs and mice. Over time, these seals can begin to crack and weaken due to normal wear and tear and exposure to the elements.

When this happens, the window unit has to work harder to cool the room, leading to energy inefficiencies and higher energy bills. This can also lead to more frequent maintenance and repairs, potentially shortening the lifespan of your air conditioner.

Fortunately, replacing the weather seals every two years can help ensure your window unit runs as efficiently as possible. Thankfully, this is a simple and relatively inexpensive repair. Presbond carries a standard 1/2" thick x 1" width all purpose weather seal for this exact purpose. Instead of purchasing additional tools, we suggest using a spackling blade that is used for drywall.

Once youve got the seals, the installation process usually takes no more than a few minutes. To complete the job, start by removing the current seal using the tool you purchased. Then, replace it with the new seal and make sure the seal fits snugly so you wont have to do it again anytime soon.

It's important to note that weather seals should only be used in conjunction with a window kit. A window kit helps support the weight of the unit, and having the right one can be the difference between having a properly sealed unit or an inefficient one that results in higher energy costs. Installing a window kit may require the help of a professional, so you should consider calling a contractor for assistance.

The bottom line is that replacing your window unit air conditioners weather seals is an essential maintenance step that comes with many benefits. In addition to reducing your energy costs, it will also help ensure the longevity of your air conditioner, giving you peace of mind that youll be able to stay cool for years to come.
