How Do I Know If My AC Run Capacitor Is Bad?

Introduction

When the sweltering heat of summer hits, your air conditioning unit becomes your best friend. But what happens when that friend doesn't seem to be working quite right? More specifically, how do you know if your AC run capacitor is bad? The run capacitor plays a crucial role in ensuring your AC runs smoothly and efficiently. If it’s malfunctioning, you might face a Season Control Heating & Air Conditioning myriad of issues that can lead to discomfort and costly repairs.

Understanding how to identify a bad capacitor is essential for maintaining your AC system's health. In this article, we'll delve into the nitty-gritty details of AC run capacitors, what they do, how to spot problems, and when to call for professional AC repair in Van Nuys.

What is an AC Run Capacitor?

The Role of a Run Capacitor in Your Air Conditioning System

An AC run capacitor is an electrical component that stores energy and releases it to help start and run the compressor and fan motor. Without a functioning capacitor, your air conditioner may struggle to operate effectively.

Types of Capacitors Used in Air Conditioners

There are two main types of capacitors used in air conditioning systems:

• Run Capacitors: These maintain the operation of the motor during its running phase.
• Start Capacitors: These provide a boost of energy to start the motor before quickly disengaging.

Understanding which capacitor is failing can help pinpoint issues faster.
