Understanding the Role of Capacitors in Your System

In the orchestra of your home’s Heating, Ventilation, and Air Conditioning (HVAC) system, you’ll find various components each playing their own instrumental part to maintain your comfort throughout the seasons. One often overlooked, but vital player is the capacitor. This humble device, while small, plays a pivotal role in ensuring your HVAC system functions smoothly and efficiently.

A capacitor's primary role is to store and release electrical energy at specific times

Storing and Releasing Energy

A capacitor’s primary role is to store and release electrical energy at specific times. You can think of it like a battery; however, instead of providing long-term power, a capacitor delivers short, powerful bursts of energy to start or keep motors running in your HVAC system.

There are two types of capacitors commonly found in residential HVAC systems - the start capacitor and the run capacitor

Types of Capacitors

There are two types of capacitors commonly found in residential HVAC systems – the start capacitor and the run capacitor. Start capacitors provide that initial jolt of energy needed to get your system’s motor running, while run capacitors provide ongoing energy to keep the motor operational.

The start capacitor acts as the initial push, getting the sprinter off the starting block. Once the sprinter is running, the run capacitor takes over, providing the steady energy to keep the sprinter moving towards the finish line.

Giving a Little Push

Imagine a sprinter at the start of a race. The start capacitor acts as the initial push, getting the sprinter off the starting block. Once the sprinter is running, the run capacitor takes over, providing the steady energy to keep the sprinter moving towards the finish line.

The Importance of Regular Maintenance

Regular HVAC maintenance is crucial to ensure these capacitors are in good shape. If a capacitor fails, it could result in an overworked motor or, worse, a motor that won’t start at all, leading to uncomfortable temperatures in your home.

If you are a member of our comfort club, our HVAC technicians at Brooks Heating and Air can check your system’s capacitors during routine maintenance visits. They’ll look for signs of wear and tear or potential failure. If a capacitor needs replacing, we can do it on the spot, ensuring your system continues to work efficiently.
