Why Is My AC Running All the Time?

You can expect your air conditioning system to run more often when the outdoor temperature rises. But there’s a difference between an AC running often because it’s needed and running almost all the time. Air conditioning systems are designed to work in cooling cycles that continue until the thermostat has registered that the AC has hit the target temperature on the thermostat, after which the unit will cycle down for a stretch. Most cooling cycles will last 10 to 15 minutes, with a similar period in between cycles.

If your AC is running much longer than 15 minutes and seems to be on most of the time (often leading to a house that’s too cool even for a hot day), then you likely have a malfunctioning system. The AC may be in danger of a full breakdown, and you’ll also face extremely high energy bills from all the extra time the air conditioner is blasting away.

Sometimes there is a simple explanation. In other situations, you’ll need to schedule air conditioner repair in Nashville with professionals.

What Can Cause an AC to Run Too Often?

There are several potential reasons why your air conditioner might be running more frequently than it should. Here are some of the most common issues:

  • Dirty air filter: A clogged air filter restricts airflow, causing the AC to work harder to circulate air throughout your home. This extra effort can result in the system running longer than necessary to achieve the desired temperature.
  • Thermostat problems: If the thermostat is malfunctioning or placed in a location that inaccurately reflects the home’s overall temperature (such as near a window or in direct sunlight), it might signal the AC to keep running, thinking the house hasn’t reached the set temperature.
  • Leaking refrigerant: Low refrigerant levels due to a leak can cause the AC to lose its cooling efficiency. The system will struggle to cool the air effectively, resulting in longer run times as it tries to compensate.
  • Undersized AC: An AC unit that’s too small for your home will run constantly as it tries (and fails) to reach the target temperature. The only solution to this problem is to replace the AC and have professionals do a proper sizing.
  • Blocked condenser coils: The outdoor condenser coils can become dirty or blocked, preventing the AC from releasing heat effectively. This condition forces the AC to run longer to cool your home.
  • Duct leaks: If your home’s ductwork has air leaks, the escaping air will cause a cooling deficit—and the AC will need to keep running as it tries to make up for that lost cool air.
