If you’ve noticed your air conditioning system struggling to keep up, especially during hot days, you might be experiencing issues with your AC capacitor. This component is crucial for the efficient operation of your HVAC system, and when it fails, it can cause a significant downturn in performance.
At Green Energy Mechanical Inc., we’ve seen our fair share of these issues right here in Milton, MA. In this guide, our team will explain why your AC capacitor keeps failing and when to contact Milton’s premier AC repair team.
What Does the AC Capacitor Do?
The AC capacitor is essentially the battery that helps power the motors responsible for running your air conditioning system. It stores the electrical energy needed to start the compressor and the fan motors. Without a functioning capacitor, your system might not start up or may malfunction while running.
This component is integral in ensuring a smooth and efficient operation of your AC unit, acting as a critical enabler for the starting cycle of the motors. A failure in the capacitor means that the motors do not receive the necessary initial boost, leading to ineffective functioning or a complete system halt.
Common Reasons for an AC Capacitor To Fail
Capacitors are subject to wear and tear, just like any other component of your HVAC system. If your AC capacitor keeps failing, here are a few possible reasons.
Heat Exposure
Capacitors are particularly sensitive to heat. Inside an air conditioning unit, if the capacitor is exposed to excessive temperatures, it can lose its ability to hold an electric charge. This typically occurs when the unit is placed in direct sunlight or in a poorly ventilated area. Overheating not only reduces the capacitor’s efficiency but also significantly shortens its lifespan, making regular checks and proper installation crucial.
Electrical Overloads
Your AC capacitor is designed to handle a specific voltage. When this limit is exceeded due to power surges or lightning strikes, it can lead to capacitor failure. This is a common issue during stormy weather, and it underscores why surge protection is vital for your home’s electrical systems. A well-installed surge protector can help prevent these voltage spikes from damaging your HVAC components.
Improper Installation or Faulty Equipment
If your AC capacitor keeps failing, it could simply be due to improper installation. Incorrect installation may lead to continuous operational stress, while factory defects in capacitors can also precipitate early failures.
Using high-quality, correctly installed capacitors can significantly reduce the risk of failure. It’s essential to ensure that HVAC professionals handle installation and maintenance to avoid these issues.
How To Determine If the Capacitor Is the Problem
Identifying a failing capacitor can be tricky without professional tools, but there are signs you can look out for:
- System Struggles to Start: If your AC system hesitates upon startup or you hear a humming noise, it might be due to a failing capacitor.
- System Shuts Off Randomly: A faulty capacitor can cause your AC system to shut down unexpectedly due to a lack of power to run the motors.
- High Energy Bills: An inefficient capacitor might make your system work harder, which can lead to higher energy bills.
If you notice any of these signs, it’s best to call a professional to inspect your system. Handling capacitors can be dangerous due to the electrical charge they hold.
What To Do When You Have a Failing AC Capacitor
If your AC capacitor is failing, there are a few things you can do to get it back up and running:
- Contact a Professional: Handling electrical components can be hazardous. Trained technicians can safely diagnose and replace faulty capacitors, ensuring your system runs smoothly.
- Regular Maintenance: Prevent capacitor issues before they start with regular maintenance checks. These can help identify potential problems early on, saving you time and money.
- Upgrade Your Capacitor: Consider upgrading to a higher-quality capacitor if failures are frequent. This might be more cost-effective in the long run.
