    What To Look For in a Window A/C Unit

    As you look through your window A/C options, you’ll see an assortment of features that promise to improve your unit. Here are a few of the more common ones you’ll find to provide some insight into how window A/C units work. Consider which features are most important to you before starting to shop.

    Cooling Area

    The size of the room can make or break the effectiveness of your air conditioning unit. A window A/C unit is typically rated in BTUs or British thermal units. Small rooms can get away with a unit that has a 5,000 BTU rating, but a larger room will likely need window air conditioners with 10,000 BTUs or more.

    To determine the size of the air conditioner you’ll need, first measure the square footage of the room you’re seeking to cool. Take that number and multiply it by 25. This will give you an estimate of the BTUs you’ll need from your window A/C unit. For example, a 20-foot by 10-foot bedroom has 200 square feet and will need a 5,000 BTU unit to cool it efficiently. To reduce the cost of running an 8000 BTU A/C, make sure the room you place it in is not much bigger than 350 square feet.

    Make sure the unit you choose has enough cooling power. A unit that’s too small won’t be as effective, won’t last as long, and won’t yield the energy savings you’d get from a properly sized unit.

    Energy Star Certification

    In years past, window A/C units had a bad reputation for being energy hogs. But today’s options are full of Energy Star-certified products that promise to lower utility bills.


    Window A/C units may have washable filters or replaceable filters. Reusable filters can help keep your costs down but aren’t always available. When researching window air conditioners, consider the type of filter it requires, how much they cost, and how readily available they are. It’s even better when the unit has a feature that tells you when your filter is ready to be cleaned.

    Noise Levels

    Window A/C units will produce varying levels of noise as they work, measured in decibels and included in part of the product’s specification. Most window air conditioners run at about 60 decibels, but some of the quietest on the market are around 40 decibels. Consider how you use the room and determine how much of a factor noise should be in making your decision. It may be worth paying extra for a quieter model for a baby’s room or library.


    A window A/C unit can range anywhere from $150 to more than $500. Pricing is primarily based on the size of the unit, but features like remote control, varying fan speeds, and reduced noise can drive up the price of a particular model.

    Temperature Range Settings

    Most window A/C units can range in temperature between 62 and 82 degrees Fahrenheit. If you are particular about the temperature of your room, check the range to ensure your numbers fit within it.


    Most windows can hold a window A/C unit of any weight, but heavier units are harder to install. The smallest window air conditioners weigh around 35 pounds, while larger units can clock in at well over 80 pounds. Keep this in mind if you are installing the unit yourself.

    Wi-Fi Capability

    Some more advanced window A/C units can connect to your home Wi-Fi network, allowing you to control the unit from your phone or other smart-home devices.

    Window Size

    Air conditioning units are designed for a particular size of window. Measure the width and height of your window opening, and write these numbers down. Many window air conditioning units come with adjustable pieces to help them fit in a wide range of windows, but you still have to ensure your window is within the range of the model you select.

    While you’re at it, also note the style of window you have. Single-hung and double-hung windows are the most common and will work with most window A/C units. But more unusual window types like awning or jalousie windows may not work.

    Air Conditioner Maintenance Tips

    Here are a few tips to ensure that you keep your window A/C in great condition for years to come.

    • Keep it clean. Clean the filter often. Clogged filters are a common reason why window AC units fail. If your unit has a filter light, pay close attention to see when it needs maintenance. If not, remind yourself to clean the filter monthly. Also, always keep the outside of the unit clean and free of debris.
    • Make sure you have the right size. Always choose the right size air conditioner so you don’t strain the unit and cause more issues in your home.
    • Dim the light. Help the air conditioner by taking other precautions to keep the temperature down. Window shades and blinds can make a tremendous difference.
    • Check your home warranty. Some home warranty plans have coverage for HVAC that will extend to window A/C units. Double-check before buying or renewing your home warranty so you can be confident you’ll have help if it breaks.
