In the midst of sweltering summer heat and high humidity, the last situation that you want is a non-working air conditioning system. However, faulty parts, old age, and other unpredictable factors can cause inconvenient shutdowns and the need for a professional A/C repair technician. Below, learn about the common reasons why air conditioning systems will fail to operate properly so that you can avoid a breakdown when you need your A/C the most. 

4 Reasons Why A/C Systems Shut Down

1. Fan Issues

The fans inside air conditioning systems help channel air over the condenser and evaporator coil to keep interior spaces cool and expel unwanted warm air. When the fans’ belts are damaged, airflow can be spotty or non-existent. If the fan’s components do not have adequate lubrication or if the motor is malfunctioning, an A/C repair technician will need to make the necessary fixes to prevent permanent damage. 

2. Low Refrigerant Level

Air conditioning systems rely on refrigerant to consistently cool the air within the units. When levels are lower than what the manufacturer recommends, there may be a leak, which can stop cold air distribution. Servicing the system requires more than replenishing the refrigerant. An A/C repair professional will find and fix the source of the leak or damage before replacing the refrigerant. 

3. Faulty Thermostat

Incorrect calibrations on older thermostats may cause a disconnect between the air conditioning system and the temperature settings. On newer, programmable thermostats, it can be an initial challenge to set them properly. This common A/C issue is typically fairly easy to fix. A new thermostat may be needed, or a quick review of the owner’s manual can help with instructions to ensure the settings are correct.  

4. Neglected Air Filters

When the warmer weather approaches, air conditioning systems are working around the clock to keep homes comfortable. Before you turn on your unit for the summer, ensure that your HVAC technician inspects and changes the filter. Most units have air filters, which can help capture dirt, dust, and other pollutants in the air.

When the filters become clogged, proper air circulation doesn’t occur. This can trigger allergies, mold growth, and respiratory problems. Air filters should generally be replaced once a month, especially if there are pets or smokers in the home. Depending on the A/C system, some filters can remain in place for up to three months.
