Why is my AC running but not cooling?

5 Reasons Why Your AC Is Running But Not Cooling

Why is my AC running but not cooling? As summers are rolling-in, nothing is more frustrating than finding that your air conditioner is running but not cooling.

We know how difficult this is in the extreme heat of the United Arab Emirates. In this article we are going to help you understand why your air conditioner is not cooling the house and most importantly what you can do to fix your air conditioner.

Your air conditioner is more than just an annoyance when it turns on but doesn’t cool your space, it’s a sign that something is not right.

Let’s examine the seven most frequent reasons for this annoying issue and how to effectively address them: 

  • Thermostats Issues

Let’s start by examining the first potential part of your AC which could be the thermostat because issues could stem from it. If your thermostat is providing inaccurate temperature readings or experiencing poor communication with the air conditioning system, it could lead to ineffective cooling. To address this, consider replacing or calibrating the thermostat for precise temperature control and proper communication with the AC equipment.

  • Dirty Air Filters

If your air conditioner’s thermostat is functioning correctly but you’re still not experiencing cool air, the next step is to check your system’s air filter. Located in or near the indoor air handler unit, the air filter captures dirt, dust, and other airborne particles, ensuring cleaner and more efficient operation of your AC system.

A clean air filter is crucial for proper airflow and cooling effectiveness. If upon inspection you find the air filter to be clean and unobstructed, you may need to address other potential issues affecting your AC system’s performance.

  • Blocked or Clogged Condenser Coil

One common issue could be a blocked or clogged condenser coil. Over time, dirt, debris, or leaves can accumulate and block the condenser coil, reducing cooling effectiveness and hindering heat exchange.

Regular maintenance, including cleaning the condenser coil to remove accumulated debris, is essential to ensure unhindered airflow and efficient heat exchange. Additionally, maintaining sufficient clearance around the condenser unit by trimming foliage can help optimize performance.

  • Refrigerant leaks

Refrigerant plays a crucial role in the cooling process of your air conditioning system. As it cycles through the system’s interior and outdoor coils, it absorbs heat energy and humidity from indoor air, transforming from liquid to gaseous form and releasing heat outdoors. However, refrigerant leaks can lead to low refrigerant levels, diminishing the cooling capacity of the AC system and potentially causing damage.

To address this issue, it’s essential to identify and repair refrigerant leaks promptly. Once the leaks are fixed, the system needs to be recharged with the appropriate amount of refrigerant to restore optimal cooling performance.

  • Damaged Heat Pump

Lastly, damage to the heat pump can compromise its ability to transfer heat properly, reducing the AC system’s cooling capacity. To address this issue, damaged parts of the heat pump should be replaced or repaired to restore effective heat transfer and maintain the system’s operation.

Regular maintenance and prompt resolution of any issues are essential for ensuring optimal performance and longevity of your air conditioning system.
