Get the Cool Back In Your Home

When the summer heat in Charleston reaches its peak, the last thing you want is an air conditioner that fails to blow cold air. This issue can transform your home from a comfortable sanctuary into a sweltering hotbox. Understanding the common causes behind this problem can help you identify the right solution quickly.

1. Dirty Air Filters

One of the most frequent culprits is a dirty air filter. Over time, dust and debris accumulate in the filter, obstructing airflow and significantly reducing the system’s efficiency. This blockage can prevent your AC from blowing cold air. Regularly checking and replacing your air filters can prevent this issue and improve air quality in your home.

2. Low Refrigerant Levels

The refrigerant is the lifeblood of your air conditioning system, absorbing heat from your home’s interior and releasing it outside. Low levels due to leaks or other issues can impair your AC’s ability to cool the air effectively. If you suspect a refrigerant leak, it’s crucial to contact a professional HVAC technician, as handling refrigerant requires specialized knowledge and equipment.

3. Faulty Thermostat

Sometimes, the problem isn’t with the air conditioner itself but with the thermostat. A malfunctioning thermostat can fail to communicate properly with the AC unit, leading to inadequate cooling. Ensure your thermostat is set correctly and consider upgrading to a smart thermostat for more precise control over your home’s temperature.

4. Frozen Evaporator Coils

The evaporator coils in your AC unit are responsible for absorbing heat from the air in your home. However, if the airflow is insufficient or if refrigerant levels are too low, these coils can freeze over, preventing your air conditioner from cooling the air effectively. Regular maintenance is essential to keep these coils in good working condition.

5. Worn Out Compressor

The compressor is the heart of your air conditioning system, circulating the refrigerant between the evaporator and condenser coils. A malfunctioning compressor can lead to poor cooling performance. Compressor issues are complex and typically require professional diagnosis and repair.
