AC Running Constantly? Ignore It And You’ll Regret It


When the hot summer months arrive, there's nothing more comforting than the cool air provided by your air conditioner. However, if you find that your AC is running constantly without any respite, it's a sign that something is amiss. Ignoring this issue can lead to various problems, both financially and in terms of your comfort. In this article, we'll explore why you can't afford to overlook your AC running constantly, the consequences it can have, and the common causes behind this issue.

Why you can’t afford to ignore your AC running constantly

When your air conditioner operates non-stop, there are several reasons why it should concern you:


An AC unit that runs constantly consumes a significant amount of energy, resulting in higher electricity bills. This continuous operation leads to unnecessary energy wastage and financial losses in the long run.


The constant running of your AC puts excessive strain on its components, leading to increased wear and tear. The system's critical parts such as the compressor, motor, and fan endure more stress, reducing their lifespan. This continuous strain also raises the risk of breakdowns, leaving you without cool air when you need it the most.


If you choose to ignore your AC running constantly, you're inviting a potential system failure. The continuous operation is a clear indication that something is wrong with your air conditioner. Failure to address the underlying problem promptly can result in complete system breakdown, leaving you with no cooling relief in the sweltering heat.

Most common causes of your AC running constantly

To help you troubleshoot your AC and determine the urgency of the problem, let's explore some common causes of your AC running constantly:

1. Frozen coils

When your AC blows warm air instead of cold air and runs constantly, it's likely that the coils have frozen up. This situation often occurs when the system hasn't received proper maintenance. To prevent further damage, it's essential to turn off the air conditioner immediately and seek professional assistance to diagnose the cause and rectify the issue.

2. Condenser and/or evaporator coils need cleaning

If you haven't serviced your air conditioner this spring, the condenser and evaporator coils may be covered in dirt and debris. This accumulation impedes the cooling process, forcing the unit to work harder to maintain the desired temperature. The increased workload leads to the AC running constantly.

Regular cleaning of both the evaporator coils in the indoor unit and the condenser coils in the outdoor unit is crucial to ensure efficient airflow. Dirt, debris, leaves, and even animal or insect nests can obstruct the coils, hindering their ability to cool effectively. Hiring a professional to perform a thorough cleaning using safe products and appropriate tools is the best way to address this problem.


Ignoring the fact that your AC is running constantly can have serious consequences. It not only wastes energy and increases your utility bills but also puts unnecessary strain on your air conditioner's components, shortening its lifespan. Furthermore, failing to address the underlying problem promptly can lead to a complete system breakdown. To avoid these issues, it's essential to take immediate action and seek professional help when your AC is running constantly.
