In this article, we will explore the best places to buy AC capacitors locally, their strengths and weaknesses, and answer some FAQs. Let’s get started!


AC capacitors are an essential component to keep your air conditioning running smoothly. When capacitors fail, your air conditioning system can stop working, leaving you to swelter in the summer heat. Finding a new capacitor, however, can be a challenge for many people as they may not know where to start looking. Luckily, there are several options when searching for where to buy AC capacitor locally.

In this comprehensive guide, we will explore the different places you can look to purchase AC capacitors. We’ll also dive into the strengths and weaknesses of these options, giving you a clear idea of what will work best for you. Let’s start with the different types of AC capacitors and their main function in air conditioning units.

Types of AC Capacitors

AC capacitors come in two main types: start capacitors and run capacitors. The start capacitor provides a boost of power to the motor to initiate the rotation of the AC unit’s compressor. The run capacitor works continuously while the unit is running to keep the motor running and provide a stable flow of electricity. Make sure to get the right capacitor for your AC unit to ensure it works efficiently.

Where to Buy AC Capacitor Locally

There are several options when it comes to purchasing AC capacitors locally. Here are some of the most popular choices to consider:

1. HVAC Supply Stores

One of the most reliable options is to visit an HVAC supply store in your area. These stores specialize in heating and cooling components and often have a variety of capacitors available. The staff can help you find the right capacitor for your AC unit, making the process much more manageable.

Pro: HVAC stores carry a wide range of capacitors, and the staff can assist you in selecting the right one.

Con: HVAC stores can be more expensive than other options.

2. Home Improvement Stores

Another option is to visit a home improvement store, such as Home Depot or Lowe’s. These stores often have a selection of capacitors available, and prices may be lower than at an HVAC store. However, staff at these stores may not be as knowledgeable about AC capacitors’ specific needs.
