What Is the Furnace Heat Exchanger & Why Does It Need Maintenance?, Nicholasville, Kentucky

Your furnace is comprised of a number of important parts that work together to deliver warm air throughout your home. One of the most crucial components is called the heat exchanger. The sections below explain what the heat exchanger is, how it works, and why it needs to be a part of your annual HVAC maintenance routine.

What Is the Heat Exchanger?

The heat exchanger is a series of metal tubes or coils that collect the heat generated by the furnace's burn chamber. Once these are hot, the blower blows household-temperature air across these coils, so heat is exchanged.

Heat exchanger in Lexington, KYThe warmed air moves through your household ducts and into the home. In other words, the heat exchanger is the part of the furnace that actually heats the air and keeps you warm. It is a vital component, and therefore, requires regular HVAC maintenance. Left uninspected, it could pose a risk to you and your family.

Why Does the Heat Exchanger Need Regular HVAC Maintenance?

The heat exchanger undergoes dramatic temperature changes. These swings cause the affected components to expand and contract, and this can lead to stress cracks. A cracked heat exchanger could allow any of the toxic gases—for instance, carbon monoxide, sulfur dioxide, and nitrous oxide—that are normally vented outdoors to leak into the home.

At high enough concentrations, these gases can be dangerous or even deadly. Therefore, it's important for an HVAC maintenance professional to examine the heat exchanger and other furnace components each year to make sure they're all operating safely.
