Buyers Guide: Things to Consider Before Buying a Window Air Conditioner

Energy Efficiency: If you have a huge consideration about how much energy you air conditioner would be consuming, then you would need to look out for it’s energy efficiency rating. You spend less on home electricity bills, if the energy efficiency rating is high.

Some window air conditioners have an energy-saver switch, which ensures that the fans stop at intervals. Some others have sleep modes, which cause the room temperature to rise at night.

The BTU (British Thermal Unit) of the window air conditioner should also be considered when saving energy. The faster an air conditioner can cool a space, depends on the number of BTUs it has. Consequently, higher BTU air conditioners can cool larger spaces. They however, require a lot of electrical energy as well. As a result, higher BTU means higher electrical bills.

The size of your space: Another thing you should consider before you go ahead to purchase your window air conditioner, is the size of the space you want to cool. A large space would require an air conditioner with high BTU, or you could go with the square footage of the room you want to cool.

It is important to get the right size unit for your space, because you don’t want to end up getting a high capacity you don’t need, which will make you have high electricity bills. On the other hand, a unit that is too small for your space will be inefficient.

The height and width of the window opening is also an important measurement to consider, to ensure that the unit fits perfectly.

Features: You may want to consider the features that the air conditioner has, before you purchase it. Some of the different features are, energy saver, night mode, a check filter indicator, which reminds you to change or clean the filter.

A good number of window air conditioners come with remotes, which come in handy for adjusting temperatures. Some are even WiFi-enabled, which means you can operate your air conditioner from your phone.

Price: You, of course need to determine how much you want to spend on the air conditioner. The prices are dependent on the different features of the air conditioner. A good number of them are affordable.
