Is your once-reliable air conditioner suddenly blowing hot air, leaving you sweltering instead of cool? Don’t despair! Several common culprits could be behind this frustrating situation. Before calling in an HVAC professional, there are a few simple troubleshooting steps you can try to get your cool air flowing again. Visit now Texas Strong Air Conditioning

Checking the Obvious:

  • Thermostat Settings: Double-check your thermostat settings. Ensure it’s set to “cool” mode and the desired cool temperature is selected. You might be surprised at how often a simple setting mistake can cause a big problem.
  • Fan Mode: Verify the fan is set to “auto” instead of “on.” In “on” mode, the fan will constantly circulate air, potentially blowing warm indoor air even when the AC isn’t actively cooling.

Airflow Issues:

  • Clogged Air Filter: A clogged air filter is a frequent culprit for AC woes. A dirty filter restricts airflow, hindering the system’s ability to cool the air effectively. Check your air filter and replace it if necessary. Most filters require replacement every 1-3 months, depending on usage and filter type.

Outdoor Unit Blues:

  • Dirty Condenser Coil: The condenser coil, located outside your home, releases heat from the refrigerant. Over time, the coil can accumulate dirt, leaves, and debris, reducing its ability to dissipate heat. Carefully clean the condenser coil with a soft brush or hose (avoid using a pressure washer, which can damage the delicate fins).

Beyond the Basics:

If you’ve checked the thermostat settings, air filter, and condenser coil, and your AC is still blowing hot air, it might be time to call in a professional. Here are some potential causes that require professional attention:

  • Low Refrigerant Levels: Your air conditioner relies on refrigerant to absorb heat indoors and release it outdoors. Low refrigerant levels can significantly reduce cooling efficiency. A qualified technician can diagnose a refrigerant leak and recharge the system if necessary. Important note: Never attempt to add refrigerant yourself, as it’s a pressurized system that requires specialized training and tools to handle safely.
  • Frozen Coils: Frozen evaporator coils can also prevent your AC from cooling properly. This can be caused by restricted airflow, low refrigerant levels, or a malfunctioning system component. A technician can diagnose and address the root cause of the frozen coils.

Preventive Maintenance:

By following these simple troubleshooting steps and scheduling regular maintenance by a qualified HVAC professional, you can keep your air conditioner running smoothly and efficiently, ensuring cool comfort throughout the summer.
