How Long Do Evaporator Coils Last?

The average coil should last 12 to 15 years. In general, you can expect your evaporator coil to last as long as your HVAC system, but that's not always the case. In many cases, evaporator coils last about 12 to 15 years and can be expensive to replace. However, you do have some control, since your maintenance routine and the quality of your HVAC system can influence the lifespan of the coils.

Repair or Replace?

When it comes to air conditioner coil repairs and replacements, the age of your system is a key factor. If you have an older system, your technician may suggest it’s time to replace your HVAC unit instead of simply fixing your evaporator coil. After all, most HVAC systems only last about 12 or 15 years, so if your coil is failing after 10 years of hard work, it’s likely a sign of things to come as your system starts to break down. They’re vital parts in your system, so it’s not uncommon for overworked coils to malfunction before you notice problems elsewhere.

Make It Last

While the average HVAC coil lasts less than two decades, there are a few things you can do to help extend the lifespan of your coil (and potentially your system). Regular maintenance and filter cleaning can help keep your system in tip-top shape. It's also good to ask your HVAC technician during your yearly maintenance checks about the quality of your filters, since higher quality filters can help manage dust buildup in particularly dusty spaces.
