How Much Does it Cost to Replace an AC Contactor in 2024?

In the complex world of HVAC systems, AC contactors quietly perform a crucial role. These small yet vital components transfer power within your unit, ensuring it operates efficiently.

This post explores the lifespan, common causes of wear, and replacement costs for AC contactors, which range from $200 to $600.

The Role of Contactors:

A contactor is a fundamental component in HVAC systems. Its primary function involves taking a 24-volt signal from the internal components and utilizing it to close a set of contacts. This action facilitates the flow of power, energizing your unit to provide cooling or heating as needed. While often overlooked, contactors are the crucial link between the control signals and the high-voltage power that drives your HVAC system.

From the video:

“This is a contactor. These are a very important part. What it actually does is it takes a 24-volt signal from your inside and then it closes a set of contacts on here to actually send power through to power your unit.

Typically what happens with these is they start to get pitted through overamping and other factors. Typically these will last anywhere from seven to ten years. Cost to replace these is usually anywhere from $200 and up, and that’s what I tell people about this part.”

Lifespan and Wear:

As with any mechanical component, contactors are subject to wear over time. Pitting, a common issue caused by factors like overamping and wear and tear, can affect their efficiency. Typically, contactors are designed to last around seven to ten years before these issues become significant enough to warrant replacement. Regular maintenance can prolong their lifespan, but replacement eventually becomes inevitable.
