One of the pieces of advice you often see regarding central air systems is that the fan needs to be on the AUTO setting. This setting links the fan to the thermostat; when the air conditioner compressor turns on, the fan will turn on, and when the compressor turns off, the fan will turn off.
For some people, that advice may seem meaningless. If it's hot, they want air circulating to combat the summer heat.
As a homeowner with an air conditioning system, it's beneficial to get your system serviced before you need to use it everyday. As the warm weather approaches, it's time to schedule residential AC services to have your system tuned for the hard work ahead. While you can wait until you need to turn on your air conditioning every day, you are taking the chance that your system is not going to be efficient.
