Why Does Your AC Run Non-Stop? Find Out

Posted on

Air conditioning is necessary for providing optimum indoor conditions during summer. Unfortunately, your system sustains age-related deterioration over time, hindering its operation. For instance, your AC could be failing if it is constantly running without stopping. This issue may result in excess energy usage. Besides that, it makes your system vulnerable to breakdowns. So if your cooling system is running non-stop, hire an AC professional to diagnose and fix the problem immediately. The following are the reasons your AC is running irregularly.

Frozen Evaporator Coil

The refrigerant flows through the evaporator coil, absorbing heat and expelling it outdoors. However, dirt can accumulate on the coil due to system dormancy, restricting heat transfer. In addition, dirt can bypass clogged filters and collect on the coil. A dirt build-up on the coils makes the cold refrigerant flow without absorbing heat effectively. Consequently, the temperature inside the coil will fall drastically, leading to the coil freezing. As a result, the system has to run non-stop to absorb as much heat as possible in the evaporator coil.

Faulty Thermostat

A thermostat will display the room temperature and allow you to adjust it to your desired level. But over time, pet dander, dust, and other airborne particulates build up in the thermostat. This might impede the sensor's operation, leading to false temperature detection. As a result, the thermostat will send erratic signals to the AC, making it continue running cooling cycles. Moreover, the wrong thermostat's location can affect its performance. For instance, placing your thermostat near direct sunlight will cause the AC to detect warmer temperatures. This causes the unit to operate in overdrive to cool your home adequately.

Leaky Ducts

The ducts distribute cool air from the AC to your home through vents. However, critters can invade and eat through your ductwork, causing it to leak air. On the other hand, ducts sustain metal fatigue due to constant temperature fluctuation. That means the ductwork will expand and contract frequently, causing it to weaken and detach. This results in cool air escaping through the holes to unconditioned spaces. As such, your home won't achieve a comfortable temperature, resulting in the AC running inconsistently.

Clogged Air Filters

An air filter removes airborne particulates from air entering through the return registers. Despite that, the filters may clog with contaminants, restricting airflow. As a result, the system will work harder to draw sufficient air for cooling. This causes your AC to run in overdrive to deliver an average cooling output. Thus, you should contact an AC specialist to clean or change your filters as often as required.

An AC that runs without stopping can spike your energy bills and is prone to malfunctions. So, call an AC repair technician as soon as you detect this problem.
