Why Is My AC Running But Not Cooling?

 It’s a hot summer day, your AC is running, but your home still feels warm and uncomfortable. Sound familiar? You’re not alone. Many homeowners face this issue and often ask, "Why is my AC running but not cooling?"

At Duct Professor, we’ve helped countless customers with this frustrating problem through expert AC service in Chicagoland. Let’s break down the common causes and what you can do about it.

1. Dirty Air Filter

A clogged air filter restricts airflow, preventing cool air from circulating effectively. This is one of the simplest and most common reasons your AC might be underperforming. Regularly replacing or cleaning your air filter is an essential part of an AC tune-up in Prospect Heights.

2. Low Refrigerant Levels

Refrigerant is what cools the air in your AC system. If it’s low or leaking, your unit may run continuously without cooling your home. Only a licensed HVAC technician should check and recharge your refrigerant levels.

3. Thermostat Issues

Sometimes the problem isn’t with your AC unit—it’s with the thermostat. If your thermostat is malfunctioning or set incorrectly, it may not be signaling your AC to cool properly.

4. Dirty or Blocked Condenser Coils

Your outdoor condenser coils release heat from your home. When they're dirty or blocked by debris, your AC can’t cool efficiently. Regular maintenance, like an AC tune-up in Prospect Heights, keeps these coils clean and working properly.

5. Faulty Compressor or Electrical Components

The compressor is the heart of your cooling system. If it’s failing, your AC may run but won’t cool effectively. This type of issue requires professional diagnosis and repair.

6. Your AC Is Too Old or Undersized

If your air conditioner is over 10–15 years old, or wasn’t properly sized during installation, it might not cool your space effectively anymore. This may be a sign it’s time to consider a new AC installation in Prospect Heights.
