5 Signs You Need AC Repair in Austin This Summer
Posted on July 10, 2025 by Delta HVAC Team

The Texas summer is no joke, and a reliable air conditioner is a necessity, not a luxury. A sudden breakdown can be stressful and expensive. The good news is that most AC units provide warning signs before they fail completely. By recognizing these signs early, you can schedule a repair and avoid a costly emergency. Here are the top 5 signs you need professional AC repair.
1. Weak or Warm Airflow
If you notice that the air coming from your vents is weaker than usual or isn't as cold as it should be, this is a major red flag. This could be caused by anything from a simple clogged filter to a more serious issue like a failing compressor or low refrigerant levels.
2. Strange Noises
Your AC system should operate relatively quietly. If you start hearing unusual sounds like grinding, squealing, clanking, or banging, it's time to call a professional. These noises often indicate a problem with the motor, a loose part, or a broken component inside the unit.
3. Unpleasant Odors
A musty or moldy smell coming from your vents could mean there's mold or mildew buildup in your ductwork or unit. A burning smell could indicate an electrical issue. Neither should be ignored, as they can impact both your health and your system's safety.
4. Frequent Cycling
While it's normal for your AC to cycle on and off to maintain the temperature, excessively frequent cycling is a problem. It could be a sign of a faulty thermostat, a clogged filter, or an improperly sized system. This not only wears out your system faster but also drives up your energy bills.
5. Moisture or Leaks
While some condensation is normal, excessive moisture or active leaks around your indoor unit are not. This could be due to a clogged condensate drain line, which can lead to water damage and mold growth, or it could be a refrigerant leak, which is a more serious health and safety concern.
