If your air conditioner is not working properly and your AC is not blowing cold air, it can be a frustrating experience—especially during hot weather. Understanding the common causes can help you determine whether it’s a simple fix or if you need emergency air conditioner repair. Here’s what might be wrong with your system and what you can do about it.

1. Dirty or Clogged Air Filter

A dirty air filter restricts airflow, making it harder for your central AC to cool your home. If you haven’t changed your filter in a while, replace it and see if your system starts working more efficiently.

2. Thermostat Issues

Sometimes, the problem isn’t with your AC but with your thermostat. Make sure it’s set to “cool” mode and that the temperature is lower than the room temperature. If the display isn’t working, you might need to replace the batteries or the thermostat itself.

3. Low Refrigerant Levels

Refrigerant is essential for cooling your home. If your system has a refrigerant leak, your AC won’t be able to produce cold air. Signs of low refrigerant include warm air from vents, ice on the coils, and hissing sounds near the unit. This issue requires HVAC emergency repair from a professional.

4. Frozen Evaporator Coils

If your AC is not blowing cold air, the evaporator coils may be frozen due to restricted airflow or low refrigerant. Turn off the system and let the coils thaw before restarting. If the issue persists, call for 24-hour A/C repair.

5. Blocked or Dirty Condenser Unit

Your outdoor condenser unit needs proper airflow to function. If it’s covered in dirt, leaves, or debris, your AC may struggle to cool your home. Clean the area around the unit and remove any obstructions.

6. Electrical or Compressor Issues

If your AC isn’t turning on at all, there could be an electrical problem or a failing compressor. A tripped breaker might be the culprit, but if resetting it doesn’t work, it’s time to call a professional to fix your central AC.

When to Call for Emergency HVAC Repair

If troubleshooting doesn’t fix the issue, or if you experience any of the following, it’s time to call for 24-hour heating and cooling services:

• Your AC won’t turn on at all.

• Your unit is leaking refrigerant or water.

• Your system is making loud or unusual noises.
