Do you have the AC running but not cooling your house? If your AC isn’t doing its job, you’re not alone. Many homeowners in Weston, FL, feel frustrated when their system is blowing warm air, especially during peak summer heat.

In this guide, we’ll explain why your AC is running but not cooling, what could be causing the issue, and when to call the pros at Greg’s Air Solutions for help.

1. Why Is My House Not Cooling Down with the AC On?

If you notice the AC running but not cooling, something isn’t right.

You might experience:

  • Weak airflow coming from the vents

  • Cool air is missing, and warm air is taking its place

  • A unit that sounds like it’s working, but your home temperature says otherwise

Sound familiar? Let’s go over the most common causes.

2. Top Reasons Why Your AC Is Blowing Warm Air

If your AC is running but not cooling, one of the following issues could be at play:

Low Refrigerant Levels

Low refrigerant = low cooling. If your refrigerant is leaking, your AC can’t absorb and remove heat effectively. The result? The AC runs but doesn’t cool the air.

Dirty AC Filter

A clogged or dirty filter reduces airflow and makes your system work harder. This is a leading cause of the AC running but not cooling your space efficiently.

Frozen AC Coils

Low refrigerant or airflow problems can cause coils to freeze, stopping your system from cooling altogether.

AC Condenser Unit Not Working

The condenser removes warm air from your home. If it’s damaged or not operating, your AC might be running but still not cooling because the heat isn’t being released outdoors.

3. Electrical & Mechanical Failures That Stop Cooling

If your AC is running but not cooling, but the filter and coils seem fine, internal mechanical problems might be the culprit:

Compressor Failure

The compressor moves refrigerant through the system. When it fails, the system may run, but no cold air comes through.

Capacitor Failure

Capacitors give the motor the boost it needs to start. If they fail, you’ll likely hear the AC hum but feel no cooling.

Blower Motor Issues

The blower circulates cooled air throughout your home. If this component breaks down, airflow suffers—even if the AC is running.

4. DIY Troubleshooting: What You Can Check Yourself

Before calling a pro, there are a few simple things you can check if your AC is running but not cooling:

  • Check and Replace the Filter: A clogged filter is the #1 cause of poor airflow.

  • Reset Your AC Unit: Turn off your system at the breaker and thermostat. Wait 5 minutes and turn it back on.

  • Clean the Coils: Dirty coils block cooling. Use a brush or coil cleaner to remove debris.

  • Thermostat Check: Make sure it’s set to “Cool” and fan on “Auto”—not “On.”

If none of this helps and the AC keeps running but not cooling, it’s time for help.
