As the temperatures soar in Ohio, air conditioning systems work overtime to keep homes cool. However, the extreme heat can take a toll on AC capacitors, leading to frequent failures. At Glass City Mechanical, our team of experts has seen firsthand the importance of proper air conditioning services in preventing such issues. In this blog post, we'll explore the reasons behind AC capacitor failures in extreme heat and what you can do to prevent them.

What are AC Capacitors and How Do They Work?

AC capacitors play a crucial role in the operation of air conditioning systems. They store energy and help regulate the flow of electrical current to the compressor and fan motors. However, when exposed to high temperatures, capacitors can degrade and fail, causing the entire system to malfunction. If you're experiencing issues with your AC system, it's essential to contact a professional HVAC maintenance service like Glass City Mechanical to diagnose and repair the problem.

Common Causes of AC Capacitor Failure

There are several reasons why AC capacitors fail in extreme heat, including:

  • Overheating: High temperatures can cause the capacitor to overheat, leading to a decrease in its lifespan.
  • Power Surges: Sudden power surges can damage the capacitor and cause it to fail.
  • Aging: Capacitors have a limited lifespan and can fail over time, especially when exposed to extreme temperatures.

Regular HVAC maintenance can help identify potential issues before they become major problems. Our team at Glass City Mechanical recommends scheduling annual maintenance checks to ensure your AC system is running efficiently and effectively. We serve various locations, including Sylvania and Rudolph, providing top-notch air conditioning services to our customers.

Preventing AC Capacitor Failure

While it's impossible to completely prevent AC capacitor failure, there are steps you can take to reduce the risk. These include:

  • Keeping your AC system clean and well-maintained
  • Ensuring proper airflow and ventilation
  • Upgrading to a high-quality capacitor

Additionally, considering HVAC installation of a new system can be beneficial if your current one is outdated. Our team can help you determine the best course of action.
