Window AC Unit

Ughh! It’s super hot and your window air conditioner has just stopped working! Time to do some research, see what a replacement is going to cost, and where to buy it. The following information will help you make the right choice.

There are several things to consider when purchasing a new window air conditioner, such as:

  • Energy Efficiency Rating
  • Cost
  • Size of your room and BTU required
  • Features
  • Venting requirements

Energy Efficiency Rating

An important consideration when choosing a unit is the Energy Efficiency Rating or EER. The higher the rating, the more efficient the unit is. The EER also indicates total energy consumption. Look for the Energy Star logo and ratings, as these products will meet the highest energy standards. This will ultimately help you save money on long term energy costs and help protect our climate.


Cost is always a factor when shopping for new appliances. Remember that the lower priced air conditioners may not be as energy efficient, and may cost more to operate than higher-priced energy-efficient units. Also, consider the manufacturer and their reputation in the industry. A lower cost unit might be made of inferior materials, not have as many features, and might have an inferior warranty. Buy once and be happy.

Size of Room and BTUs Required

In choosing the best air conditioner for your home, it is very important to consider the BTUs (British Thermal Units): the output needed to cool the space. Most units will have recommended square footage guidelines. The higher the BTU output, the larger the cooling area and vice versa. Measure the space and or spaces in your home so you can make the right choice. The following chart will give you the BTU requirements for square footage. The unit you choose will have corresponding information.

-100 to 150sq. ft. needs 5,000 BTUs
-150 to 250 sq. ft. needs 6,000 BTU’s
-250 to 300 sq. ft. needs 7,000 BTU’s
-300 to 350 sq. ft. needs 8,000 BTU’s etc….

Desired Features

Today’s air conditioners have a multitude of options and features, such as a digital display, Energy Saver mode, and variable fan speeds. Some units come with an app so you can remotely adjust settings with your smartphone. Another major factor is noise. Check the noise rating to make sure you can tolerate the level.

I hope these tips have been helpful!
