Is it normal for air conditioner to run all day?
On a normal summer day, you can expect your air conditioner to run somewhere around 15 minutes during every cooling cycle. But if your cooling cycles are lasting 30 minutes, an hour or all day long, there's a good chance that something is amiss with your system.
Your air conditioner is getting old. As air conditioners get older, they begin to lose their ability to properly cool your home. Various system components can begin to become inefficient, and your air conditioner will have to run much more often than it used to in order to keep your home cool. A new air conditioner will not only have shorter cooling cycles, but will also consume much less energy.
Your home has air leaks. Air leaks can develop around your windows and doors, as well as in your ductwork. These leaks allow conditioned air to escape your home, which means your air conditioner has to keep producing more cool air and runs more often than it should. To avoid this, be sure to seal the leaks in your home, especially in the areas around your windows and doors.
Your cooling coils are dirty. When your cooling coils are dirty, your air conditioner has a much harder time removing heat from your home. That’s why it’s so important to have them cleaned during an annual tune-up, or to contact Four Seasons if yours are dirty.
