Troubleshooting Tips for an AC That Feels Hotter Than Usual

Summertime is in full swing, and your air conditioning system becomes your closest ally in battling the sweltering heat. However, there might be times when you notice that your AC isn’t performing as it should. If you find that your AC seems hotter than usual, don’t panic; there are several potential reasons for this issue, and some of them can be easily resolved. In this blog, we will explore common causes for an underperforming AC and provide you with simple troubleshooting tips to help you regain your comfort and coolness.

  1. Check the Thermostat Settings

Before jumping to any conclusions, start with the most basic step – checking your thermostat settings. Ensure that the thermostat is set to “cool” mode and that the temperature is set at the desired level. Sometimes, a simple human error like accidentally switching the mode or adjusting the temperature can lead to the AC blowing warm air.

  1. Inspect the Air Filter

A dirty or clogged air filter is one of the most common reasons for reduced cooling efficiency in an air conditioner. A blocked air filter restricts the airflow, causing the AC to work harder and not cool the air effectively. Regularly inspect your air filter and replace it if it appears dirty or if it has been more than three months since the last replacement.

  1. Examine the Outdoor Unit

The outdoor unit of your AC system, known as the condenser unit, plays a crucial role in heat exchange. If it is covered in dirt, debris, or leaves, it can hamper its performance. Turn off the AC, and carefully clean the unit’s exterior using a hose to remove any obstructions. However, avoid using high-pressure water, as it could damage the delicate fins.

  1. Inspect for Refrigerant Leaks

Low refrigerant levels are a common cause of reduced cooling capacity. If your AC is low on refrigerant, there might be a leak in the system. It’s essential to have a professional HVAC technician inspect and repair any leaks and then recharge the refrigerant to the appropriate level.

  1. Clean the Evaporator Coils

The evaporator coils are responsible for absorbing heat from the air inside your home. Over time, these coils can become covered in dust and grime, reducing their ability to cool the air efficiently. Schedule regular maintenance with a professional technician to clean and maintain your AC system, including the evaporator coils.

  1. Check for Air Duct Leaks

Leaky air ducts can lead to cooled air escaping before it reaches your living spaces, resulting in a less effective cooling performance. Inspect your air ducts for any visible leaks or hire a professional to conduct a thorough inspection and repair any issues.

  1. Ensure Proper Insulation

Insufficient insulation in your home can lead to heat entering and cool air escaping, making your AC work harder without satisfactory results. Make sure your home is adequately insulated, especially in areas like the attic and walls, to maintain a comfortable indoor temperature.


Experiencing an AC that seems hotter than usual can be frustrating, especially during scorching summer days. However, with a systematic approach to troubleshooting, you can often identify and resolve the underlying issues. Remember always to prioritize safety and consider seeking professional help for more complex problems. Regular maintenance and proper care of your air conditioning system will not only enhance its performance but also prolong its lifespan, providing you with a cool and comfortable environment all summer long. Stay cool!
