If your air conditioner has been acting strange lately, don’t ignore the signs — it could be on the verge of a complete breakdown. At Planz Heating & Air Conditioning, we help Villa Park and Chicagoland homeowners avoid mid-summer emergencies by identifying and fixing small issues before they become major repairs. Recognizing early warning signs can save you from going days without cooling during the hottest stretch of the year.
One of the most common red flags is a sudden drop in airflow. If your vents are barely pushing out air, it could be a clogged filter, failing blower motor, or even a frozen evaporator coil. Another sign is inconsistent temperatures throughout your home — if some rooms are much warmer than others, your system is likely struggling to distribute air evenly. You might also hear new noises like grinding, rattling, or buzzing. These sounds usually point to loose parts or internal damage that could lead to system failure.
High energy bills are another clue. If you’re paying more each month but getting less comfort, your AC is working harder than it should — and that often means it’s nearing the end of its lifespan. Whether you’ve noticed one of these issues or several, it’s time to schedule a professional inspection.
