Window Unit Air Conditioning

If you’re sick of sweating through the squelching summer months, but don’t have the funds or ability to install a central air conditioning system, then you may want to consider going with a simple window unit air conditioner. They work great for apartments, or several of those rooms in a home that never seem to cool down. Here is some more information.


The cost of a window unit air conditioner depends primarily on the size of the unit and the size of the room it needs to cool. They range from $100-$300 for a room that is 150-400 square feet, or $300-$800 for larger rooms. Get in touch with a licensed HVAC contractor for more cost information.


They offer good air quality if the filter is maintained.

Window unit air conditioners are generally inexpensive to maintain.

They have the potential to cool down an area as big as 2,000 square feet depending on the size of the unit.


Window unit air conditioners cost more to operate than portable or central air conditioning systems.

Many people consider them to be eyesores.

Window unit air conditioners are considered to be one of the noisiest air conditioning units available.


If properly installed, window unit air conditioners are very sturdy, lasting an average of 10 years. If you aren’t entirely sure how to install your unit, seek the help of a professional, or make sure you follow the manufacturer’s directions carefully.


In order to ensure that your air conditioner is working properly and not harming the air quality in your space, it’s essential that you take the right steps to maintain it.

  1. Before cleaning, remove the air conditioner from the window.
  2. Take out the air filter and clean it with warm, soapy water. Let dry and put it back in the unit.
  3. Remove all dust and particles from the outside and inside of the air conditioner by using a vacuum.
  4. Clean out the drain hole with a small bottle brush.
  5. Reinstall the air conditioner.

Common Questions and Answers

How important is the square footage of a room when choosing a wall unit air conditioning system?

It’s very important. Even if you choose an air conditioner for a 700-square-foot space and put it in a 400-square-foot space, it won’t work very efficiently. Make sure you know your square footage before making a purchase.


While air conditioning (in its most primitive form) was invented at the beginning of the very beginning of the 20th century, the window unit air conditioner didn’t come on the market until just after WWII. They skyrocketed in popularity, selling 74,000 units in 1948, then 1,045,000 by 1953.
