Common Problems That Cause Air Conditioners to Run Constantly

A/C Unit

As the summer heat ramps up in South Florida, you know how crucial a properly functioning air conditioner is to survive the sweltering heat. But if your A/C just won’t quit running, you may have a problem on your hands. A bigger one than just higher than normal energy bills and inconsistent temperatures in your house. Here are a few of the most common reasons why your A/C may be running constantly and what you can do about it.

Air Filters

One of the most common culprits to a constantly running A/C is a dirty air filter. When your filter is clogged with dust and debris, it restricts airflow, causing your A/C to work harder and longer to cool your home. Make sure to clean or replace your air filter regularly to keep your A/C running efficiently.


Refrigerant leaks are another sneaky issue that can cause your AC to run non-stop. Low refrigerant levels can disrupt your A/C’s cooling process and put a strain on the system. Our skilled HVAC technicians can detect and fix any refrigerant leaks to ensure your A/C is operating at its best.


The thermostat, often overlooked, plays a crucial role in your A/C’s performance. If your thermostat is malfunctioning, it may not accurately read the temperature in your home or may have outdated programming, causing your A/C to run endlessly. Our team can help diagnose and repair thermostat issues or even upgrade to a smart thermostat for better control and energy savings.

System Size

Believe it or not, an undersized A/C unit can also lead to constant running. If your A/C is too small for your space or showing signs of aging, it may struggle to keep up with the demand, resulting in non-stop operation. Our Lindstrom experts can assess your A/C’s performance and provide recommendations for repairs or a replacement, tailored to your needs.
