Is Your AC Unit Constantly Running? Here's What Could Be Going Wrong

With sweltering summers becoming more common, an efficiently working air conditioning (AC) unit isn’t just a luxury; it’s a necessity. However, when an AC system begins to operate continuously, it doesn't just strain the unit but also significantly impacts energy bills and indoor comfort. Understanding the common culprits behind a continuously running AC unit is key to identifying quick fixes and when to call in the experts. This guide provides insights into why your cooling system may be working overtime and how to address these issues effectively.

Clogged Air Filters

When the air filter becomes clogged, it restricts airflow, causing the system to work harder to cool your home. This can lead to the unit running constantly in an effort to reach the set temperature.

Refrigerant Leaks

Refrigerant is crucial for the cooling process in your AC unit. If there is a leak in the system, it can result in a low refrigerant level, causing the unit to run continuously as it struggles to cool your home. A refrigerant leak should be addressed promptly by a professional HVAC technician to prevent further damage to your system.

Thermostat Issues

Faulty thermostat settings or a malfunctioning thermostat can also cause your AC unit to run constantly. If the thermostat is not calibrated correctly or is located in direct sunlight or near heat sources, it may inaccurately read the temperature in your home, leading to the continuous operation of the system.

Oversized AC Unit

An oversized AC unit may cool your home quickly but will cycle on and off frequently, causing increased wear and tear on the system. In some cases, an oversized unit may run constantly in an attempt to maintain a stable temperature, resulting in higher energy bills and reduced efficiency.

Poor Insulation or Air Leaks

Inadequate insulation or air leaks in your home can lead to significant heat gain, forcing your AC unit to work harder to cool the space. If warm air enters your home through gaps in windows, doors, or walls, the system will struggle to maintain a comfortable temperature, resulting in continuous operation.

Dirty Condenser Coils

Over time, dirt, debris, and grime can accumulate on the condenser coils of your outdoor unit, inhibiting heat transfer and reducing the efficiency of the system. When the condenser coils are dirty, the AC unit must work harder to remove heat from your home, causing it to run constantly.

Mechanical Malfunctions

Various mechanical issues, such as a faulty compressor, defective fan motor, or damaged components, can also cause your AC unit to run continuously. These issues require professional diagnosis and repair by an experienced HVAC technician.

In conclusion, if your AC unit is constantly running, it's essential to address the issue promptly to prevent further damage and ensure optimal performance. Contacting an HVAC contractor for inspection and repair can help identify and resolve any issues affecting your cooling system.
