5 Signs Your AC Needs Immediate Repair Before Summer

Summer in Texas is no joke. The last thing you want is for your air conditioning unit to fail when the temperatures soar into the triple digits. By catching AC issues early, you can save money on extensive repairs and keep your home comfortable all season long.

1. Blowing Warm Air

If you feel warm air blowing out of your home's vents, check the thermostat. Make sure it's switched to cooling mode and set it lower than your home's current temperature. If your vents still blow warm air, your compressor may be failing or your system could be low on refrigerant.

2. Poor Airflow

Poor airflow is a common sign that your AC isn't working efficiently. A clogged air filter, a broken motor, or an issue with your ductwork could be to blame. If you notice weak airflow in certain rooms, it's time to call a professional.

3. High Humidity Levels

Your AC should automatically moderate humidity levels. If your home feels sticky and uncomfortable, your equipment needs repair or you may need a whole-house dehumidifier.

4. Frequent Cycles

Your air conditioner should go through relatively routine cooling cycles. While it may turn on more frequently on the hottest days of summer, it shouldn't cycle on and off constantly. If you notice frequent cycling, you might need a tune-up.

5. Bad Odors

If you smell unpleasant odors coming from your HVAC system, you'll want to deal with the issue before it gets worse. A musty smell usually indicates mold or mildew inside your unit or ductwork.
