Since air conditioners maintain a comfy indoor environment, notably during sweltering summers, a well-functioning AC system not only cools your home but also enhances indoor air quality and reduces humidity. AC that doesn’t cool as it should cause a slew of issues, comprising:


A non-cooling AC system can make your home unbearably hot, causing discomfort for you and your family.

Increased Energy Consumption:

When your AC struggles to cool your home, it tends to work harder, resulting in higher energy bills

Poor Indoor Air Quality:

If your AC isn’t functioning flawlessly, it may not appropriately filter the air or regulate humidity levels, resulting in poor indoor air quality and potential health issues.

Damage to your AC system:

Ignoring the problem and consistently running a malfunctioning AC system can lead to further damage, ultimately requiring more costly repairs or even replacement.

Common Reasons for AC Not Cooling

There are several reasons why your AC system may not be cooling your home as it should. Some are encompassing below:

  • Incorrect thermostat settings
  • Dirty or clogged air filters
  • Blocked or restricted airflow around the unit
  • Low refrigerant levels
  • Malfunctioning components, such as the compressor or fan motor

Now that you’re aware of the common reasons for AC not cooling. Let’s unveil some basic troubleshooting steps you can take to resolve the issue.

You haven’t been maintaining it and one of the biggest issues with furnaces is that they are dirty. This is what it restricts airflow and prevents the system from lighting up the burners.
You didn’t calibrate the equipment when it was being installed to make sure it works right
The blower capacitor could be dead. The capacitor starts the furnace and a dying capacitor tends to lead to blower malfunction.
Your refrigerant levels could be getting too low, which results in your heat strips coming on more often than you wish. Your gas bill will suffer because of this!
Components (aka heat pumps) that have failed to start can prevent the blower of your indoor or outdoor unit from starting.
The inducer motor has burnt out and gotten dirty, which can cause safety switches to turn the furnace off.
Ductwork design and installation were not properly done. When builders and HVAC contractors cut corners, you will never really be able to properly heat up your home.

Basic Troubleshooting Steps

Before calling a professional, try these straightforward steps, saving time and money by redressing the issue yourself.

Check Your Thermostat Settings

First and foremost, ensure your thermostat settings is preset to “COOL” mode and the desired temp is lower than the current room temperature. Afterward, verify the fan is set to “AUTO” instead of “ON.” The fan setting to ON signifies it will continuously blow air, even if the AC isn’t actively cooling. Also, check the batteries regularly and replace them if required for a battery-powered thermostat. A weak battery might cause the thermostat to malfunction, leading to cooling issues.

Inspect the Air Filters

Clogged or dirty air filters can significantly impact your AC system’s performance, as they restrict airflow, making it difficult for your AC to cool your home effectively. Additionally, dirty filters can cause the evaporator coil to freeze, further exacerbating the issue. Hence, examine your air filters and replace them if they are filthy or clogged. Consider changing your air filters every 1-3 months, depending on usage and environmental factors.

Ensure Proper Air Flow Around the Unit

Ensure there’s proper airflow around your indoor and outdoor AC units. For the indoor unit, check that no furniture or other items are blocking the air vents or return grilles, as blocked ducts can significantly restrict airflow and decrease your AC system’s cooling capacity.

Subsequently, for the outdoor unit, inspect the area for any debris, such as leaves, branches, or trash, that may obstruct airflow. If you find any obstructions, carefully remove them to ensure the outdoor unit is getting proper airflow.


More Advanced Troubleshooting Steps

If you’ve tried the basic troubleshooting steps and still have issues with your AC system not cooling, try more advanced troubleshooting. But, more significantly, it’s crucial to acknowledge if you’re not confident or comfortable in handling these steps, and it’s a prudent and safe choice to seek assistance from an expert.

Examine the Condenser Coils

Importance of Clean Condenser Coils

The condenser coils release the heat absorbed by the refrigerant from your home. Dirty or clogged condenser coils can reduce your AC system’s efficiency and cooling capacity. When the coils are dirty, the AC system needs to work harder to remove heat, resulting in higher energy bills and potential damage to the system.

How to Clean Condenser Coils

How to Clean Condenser Coils

  • Turn off the power to your AC unit..
  • Remove the protective grille or panel to access the coils.
  • Use a soft brush, like a refrigerator coil brush, to gently remove dirt and debris.
  • Be cautious not to damage the delicate fins on the coils.
  • After cleaning the coils, replace the protective grille and restore power to the unit

Inspect the Refrigerant Levels

Signs of Low Refrigerant

Low refrigerant levels can cause your AC system to struggle to cool your home effectively. Telltale signs of low refrigerant include:

  • Warm air blowing from your vents
  • Long cooling cycles
  • A hissing or bubbling noise from the AC unit
  • Ice forming on the refrigerant lines


How to Add Refrigerant

Adding refrigerant to your AC system is not a DIY task. Thus, it’s essential to call a professional HVAC technician to check and refill refrigerant levels, as handling refrigerant requires specific tools and expertise.
