Recognizing a Bad AC Capacitor: Symptoms and Solutions

What is an AC Capacitor?

The AC capacitor is essentially a small electrical device that stores energy and helps start the compressor and fan motor in your air conditioning system. Without it, your unit may struggle to operate efficiently or could fail altogether.

Common Symptoms of a Failing AC Capacitor

• If you hear humming or buzzing sounds coming from your air conditioning unit, it may indicate that the capacitor is failing.

• A typical sign of a bad capacitor is when the air conditioner doesn’t turn on at all.

• If your AC turns on and off sporadically, this could be another symptom of a failing capacitor.

• A malfunctioning capacitor can force your system to work harder, leading to higher energy costs.

• If your air conditioner feels unusually hot, it might be due to an issue with the capacitor.

• Another telltale sign is if you notice uneven cooling throughout your home.

How Does an AC Capacitor Work?

AC capacitors store electrical energy and release it as needed to help start motors within the air conditioning system. They play an essential role in balancing electrical loads and ensuring smooth operation.

Types of Capacitors Used in Air Conditioning Systems

1. Start Capacitors

• These are designed for short-term use during startup.

2. Run Capacitors

• These remain engaged during regular operation, helping improve efficiency.
