If you decide to buy central air conditioning, choose one that has a seasonal energy efficiency ratio (SEER) of 13 or more. If you reside in a warm climate then buy at least a number 14. When it comes to room air conditioners, you need to buy one with an energy efficiency ratio (EER) of 11 and up.

When shopping for an air conditioning unit for the window, chose one that is suitable based on the room’s size and the number of windows in the room. Which directions the windows face towards is also significant to your decision.  Bigger is not necessarily better. If you buy an AC unit that is too large for the room then it will cost you more because the unit has to work twice as hard.

Regular maintenance on your air conditioning unit is an important way to lower your electric bill. At the start of every cooling season have the unit inspected by a professional service. During the cooling season you can do your part as well. On a monthly basis, change the filter for optimum use.

Depending on where you live and the climate, the two things in your home that use up the most energy are the heating system and the air conditioning system. If you currently have an AC that is older and has a SEER number that is 8 or less you are contributing to a higher energy bill. To lower your electric bill, purchase a more energy efficient AC with a higher SEER number.

Your air conditioning condenser should be placed in a shady area where it has plenty of space to get rid of the heated air that it takes out of the house. Make sure nothing is obstructing it from doing its job.
