How Long Can a Commercial HVAC System Last?

It’s important for building managers and owners to have a good understanding of the life expectancy of a commercial HVAC system. This can help you anticipate issues related to normal wear and prepare for the financial requirements of replacing an HVAC unit.

Below HVAC repair specialist Dittmer Air and Heat discusses the average lifespan of commercial HVAC systems, as well as the different factors that could shorten or extend it.

The Expected Lifespan of a Commercial HVAC System

Manufacturers generally claim that commercial HVAC units can last between 15 and 20 years with proper maintenance. More specifically, commercial cooling equipment such as air-cooled condensers, dampers, cooling towers and packaged chillers are normally expected to last around 20 years. If you have a commercial ductless system or a single or multi-zone commercial rooftop unit, these can usually last for about 15 years.

However, if you’ve barely maintained your commercial HVAC system, you can expect it to last for 7 to 10 years. If it’s not maintained at all, your HVAC system will probably make it approximately five years.

Factors Affecting HVAC Longevity

Needless to say, proper HVAC maintenance is key to the longevity of your commercial HVAC system. For experts, “proper maintenance” usually means scheduled preventive maintenance. The routine should include changing air filters, cleaning air ducts and other external and internal components and replacing any worn parts. It also entails a professional HVAC inspection at least once a year.

Additionally, other factors can affect the life expectancy of your HVAC system. For instance, some types of air conditioners, specifically the ones that use a two-stage mechanism, can last longer. Installation quality is also another factor to consider, as poor or incorrect installation can lead to HVAC problems, breakdowns and premature HVAC failure.
