5 Common Issues Causing AC Units to Turn Off

When the heat of summer makes everything unbearable and sweat runs down your face, your air conditioning unit becomes essential for comfort. Any issues with its cooling performance become very apparent, amplifying your discomfort. While reaching out to an air conditioning technician in Provo can provide some respite, it’s also wise to explore the possible reasons behind your unit frequently shutting off.

Thermostat Problems

A malfunctioning thermostat might result in your air conditioning unit cycling off and on too often. If the thermostat cannot accurately gauge the temperature, it sends incorrect signals to the AC’s control system, which can lead to erratic operation. Symptoms of a dying thermostat battery include flickering, blank, or dim displays, so consider replacing the batteries first.

Clogged Air Filter

For your AC system to function efficiently, it requires unhindered airflow. Air filters that are not changed regularly may become clogged with dust and debris, limiting air circulation. Insufficient air intake could cause the unit to switch on briefly and then shut down as a safety precaution. Inspect your air filters for any buildup.

Inadequate Thermostat Location

A thermostat situated close to a sun-exposed window, under supply vents, or in a warmer section of your house may yield erroneous temperature readings. This can mislead the thermostat, making it think the room is at a different temperature than it actually is. To rectify this, consulting a technician who specializes in air conditioning services in Provo may be necessary to reposition the thermostat appropriately.

Incorrect Unit Size

If your air conditioning unit is oversized, it may cool the space too rapidly, leading to poorly planned refrigerant cycles. This can cause the unit to power down shortly after starting and then activate again prematurely, leading to inefficient operation.

Contaminated Condenser Coils

Regular maintenance of your AC unit is critical, particularly before the summer heat begins. When condenser coils accumulate dirt and debris, they struggle to expel the heat being extracted from inside the home, leading to potential overheating and subsequent shutdown.

In Provo, staying comfortable during the summer months relies on effective air conditioning. Ensure that your AC system is serviced annually to prevent inconsistent cooling and avoid expensive repairs.
