Wondering why your AC is running non-stop?

On hot summer days in Texas, there’s nothing quite as comforting as the cool, refreshing air provided by your air conditioner. However, if you’ve ever noticed that your AC seems to run endlessly, you might start to worry about your energy bills and the health of your cooling system.

Air conditioning units operate in cycles to maintain a desired indoor temperature efficiently. When you set your thermostat to a specific temperature, the AC unit works to cool the air until it reaches that point and then cycles off. During this off period, the system’s fan continues to circulate the cool air to maintain the temperature, but the compressor, which consumes the most energy, is not actively cooling. This cyclical operation allows the AC to maintain comfort without running continuously, ensuring both energy efficiency and preventing unnecessary wear and tear on the system.

If your AC unit runs constantly, it’s a sign that there may be a problem that needs to be addressed to optimize its performance. In this article, we delve into the most common reasons an AC unit runs continuously and what you can do to address the issue, ensuring both your comfort and your wallet remain in good shape.

1. Inadequate Sizing

One of the most fundamental factors affecting your AC’s runtime is whether it’s appropriately sized for your space. An air conditioner that’s too small for your home will struggle to cool it down, leading to continuous operation as it tries to maintain a comfortable temperature. Conversely, an oversized AC can also run for extended periods, cycling on and off frequently, which is inefficient and can lead to wear and tear on the system.

Solution: Consult a reputable AC company to perform a load calculation for your home, ensuring that your AC unit is the right size for your cooling needs.

2. Thermostat Settings

Your thermostat plays a pivotal role in controlling your AC’s runtime. If you set the thermostat too low or leave it on the “cool” setting for an extended period, the AC will keep running to maintain that lower temperature, even when it’s not necessary.

Solution: Adjust your thermostat settings to a comfortable yet energy-efficient temperature. Consider using a programmable thermostat to create temperature schedules that align with your daily routine.

3. Air Leaks and Insulation

If your home has poor insulation or air leaks, the cool air from your AC can escape, causing the system to work harder and run longer to maintain the desired temperature. Common culprits for air leaks include gaps around windows and doors and/or insufficient insulation in walls and attics.

Solution: Identify and seal any air leaks in your home, and consider adding insulation to improve energy efficiency. This will help your AC system work less to maintain a comfortable temperature.

4. Dirty Filters and Coils

A dirty air filter or evaporator coil can impede the airflow through your AC system, causing it to run longer to cool your home adequately. When airflow is restricted, the system’s efficiency drops, and it must compensate by running more frequently.

Solution: Regularly clean or replace your air filters as recommended by the manufacturer and schedule HVAC maintenance checks with a professional to ensure coils and other components are clean and functioning optimally.

5. High Humidity

Home humidity levels play a significant role in your comfort during hot weather. When the humidity is too high, your AC has to work harder to remove moisture from the air, resulting in longer runtimes.

Solution: Consider using a dehumidifier in conjunction with your AC system to maintain comfortable humidity levels. This will reduce the workload on your AC and improve overall comfort.

6. Refrigerant Issues

Refrigerant is the lifeblood of your air conditioning system. If there’s a refrigerant leak or the system is low on refrigerant, it will struggle to cool your home efficiently, leading to extended runtimes.

Solution: If you suspect a refrigerant issue, schedule professional AC services immediately. An experienced HVAC technician can inspect your system, repair any leaks, and recharge the unit.

7. Extreme Outdoor Conditions

Sometimes, an AC running non-stop might be due to exceptionally hot and humid weather conditions. During extreme heatwaves, your AC may have to work harder and run more frequently to maintain indoor comfort.

Solution: While you can’t control the weather, you can take steps to help your AC cope, for example, using blackout curtains, sealing air leaks, keeping up with professional and DIY AC maintenance, and reducing heat-producing activities indoors
