Living in the tropics means we are fortunate to enjoy nearly 365 days of sunshine. However, with warm temperatures and high humidity levels, your air conditioner is more than merely a desire – it is a necessity. Fortunately, your AC Company is here to help.

One common issue that can affect your AC’s performance is a faulty capacitor. In this article, we’ll explain the symptoms you might notice, if this is the case.

What Is An AC Capacitor

An AC capacitor is a small, cylinder-shaped component that stores and releases electrical energy.

It helps start and run the motors in your AC system. In simple terms, you might think of it as an electrical battery for your AC.

Warm Airflow From Vents Is A Symptom Of A Bad AC Capacitor

Check your vents. If you notice weak or warm air blowing through your vents instead of cool, refreshing air, a bad capacitor could be to blame.

The capacitor helps start the motors that power the fans and compressor in your AC unit. If it fails, the result could be reduced airflow and warmer temperatures.

Short Cycling Is A Symptom Of A Bad AC Capacitor

Normally, your AC will cycle on and off periodically to maintain your desired temperature.

However, if you notice it’s constantly turning on and off without completing a full cycle, this could indicate a capacitor issue. This is the time to give your AC Company a call for a complete diagnosis.

Unusual Sound Is A Symptom Of A Bad AC Capacitor

Listen to your unit. If you hear unusual noises like clicking, humming, or buzzing, it could be a sign of capacitor trouble. The capacitor helps initiate motor movement smoothly.

AC Won’t Start Is A Symptom Of A Bad AC Capacitor

The most obvious sign of a bad capacitor is when your AC won’t start at all. If you set your thermostat to cool your home, but the AC remains silent, a failing capacitor may likely be the culprit.

Electrical issues can pose safety risks, so it’s very important for a professional to address them right away.

Higher Energy Bills Are A Symptom Of A Bad AC Capacitor

While not as obvious as some of the other symptoms, a failing capacitor can lead to increased energy use. When the motors struggle due to a bad capacitor, they become inefficient, causing your system to use more power.

If you’ve noticed an increase in your energy bill without a rise in usage, it’s worth giving your AC Company a call for a full inspection.

Age Of The Unit Can Be A Symptom Of A Bad AC Capacitor

Capacitors (like other mechanical and electrical components) have a limited lifespan. If your AC unit is more than 10 years old, it is more likely to be susceptible to burning out.

Regular maintenance can help prolong the life of these components, but eventually, the only solution may be to replace the system.

Tips To Avoid A Bad AC Capacitor

To extend the lifespan of your AC capacitors, consider these tips:

• Schedule regular HVAC maintenance check-ups with your trusted AC Company to catch and address issues early.
• Keep the area around your outdoor unit clear of debris and vegetation to allow for proper airflow.
