Keeping a central air conditioner working properly is important for at least a couple of big reasons. First, the obvious: If a central air conditioner is in ill repair, it isn’t going to work when you need it….and you’re going to cook during the hot days of summer. Second, if your central AC works but not very well, you’re bound to use far more energy than necessary to keep your house cool. By keeping your AC unit working well, you can save energy and, as a result, money.
Several different kinds of problems can occur with a central air-conditioning system.
A central AC compressor, located outdoors, should be cleaned before every cooling season.
For example, a central AC unit can stop working entirely, cool poorly, allow dramatic changes in room temperature, drip water, or make strange noises. Although some central air conditioner repairs must be handled by a qualified air-conditioning repair person, you can handle simple repairs and maintenance yourself.
