Air conditioning is a system that introduces cold air into a warm space to make it more comfortable. Air conditioning is generally used when temperatures are above 70 degrees. It is used in cars, houses, offices, retail stores, restaurants, and other indoor facilities. Unlike heat, air conditioning is considered a luxury and can be dispensed with. Heat is considered a necessity and every home should have it. However, when there are heat warnings, a lack of air conditioning can present a problem for many older people who can live in older brick houses. Without air conditioning, these types of homes literally turn into an oven at certain temperatures and can be fatal.

Alternatives to air conditioning are fans, electric or hand-held, or open windows. Air conditioning is mainly used in the summer when temperatures are higher. Therefore, electricity bills are usually higher in the summer months. Many electric companies offer budget billing, which balances high and low bills into one constant monthly payment. Budget billing is based on usage and may gradually increase over time as usage increases.

There are two types of air conditioners that are mainly used in homes. Window style units are placed in a window. The window air conditioner mainly cools the room they are in. The more expensive units can cool more than the surrounding rooms. Window air conditioners are electrically powered. They are placed in windows because the heat in the room is passed outside and exchanged with the cold air that enters. Alternatives to window air conditioning units are wall mounted air conditioners, which do not need to be placed in a window. Window units are more common in older homes.

New construction generally has built-in central air conditioning. Central air conditioning runs the air throughout the home with the actual unit located outside. A thermostat controls the temperatures in the house. Older thermostats must be manually changed to the desired temperature. Newer thermostats are programmable. Temperature settings can be programmed to change at certain times of the day. This can help reduce electricity bills by allowing the house to be warmer when it is empty. The operation of central air conditioning uses a lot of electricity, but is generally more energy efficient than window air conditioning. Many older homes use window units or do not have air conditioning.
