Air Conditioner Not Cooling? Common Causes and What to Check First

Air Conditioner Not Cooling? Common Causes and What to Check First

Before you call for AC repair, there are a few things you can check yourself. Here is a troubleshooting guide for the most common reasons your air conditioner is not cooling properly.

Start With the Basics

Before calling a technician, check your thermostat settings. Make sure it is set to cool, the temperature is set below the current room temperature, and the fan is set to auto. A thermostat set to heat or with dead batteries can easily mimic a broken AC. Next, check your circuit breaker panel. A tripped breaker can shut down your entire cooling system, and flipping it back may solve the problem immediately.

Check Your Air Filter

A clogged air filter is one of the most common and easily fixed causes of poor cooling. When the filter is dirty, airflow is restricted, which forces your system to work harder and can cause the evaporator coil to freeze. Check your filter and replace it if it looks dirty. Most filters should be replaced every one to three months depending on the type and your home environment.

When to Call a Professional

If the basics check out and your AC is still not cooling, it is time to call a licensed HVAC technician. Common professional-level issues include refrigerant leaks, compressor failures, faulty capacitors, and frozen evaporator coils. These problems require specialized tools and training to diagnose and repair safely. Attempting DIY repairs on refrigerant systems can cause further damage and may violate EPA regulations.
