Your cooling system depends on a clean ventilation system to work properly and keep your indoor environment healthy. To ensure that these things occur, you may change your air filter every three months and wipe down the outside covers of your air vents. But sometimes, even your best intentions can inadvertently cause issues with your ventilation system. For example, if your AC seems sluggish, or if your home feels stuffy and unclean, you may need to change your air filter sooner and clean out openings of your air vents.
Under normal circumstances, your AC unit should kick on for a little while, turn off again, and then kick on again when the room warms up and needs more cooling. This should happen only a few times per hour. If the air is switching on and off every few minutes, this is an issue. Your home won't cool properly, and the constant on-and-off switching will wear down the unit prematurely. Known as short-cycling, this AC behavior can indicate a number of problems.
