What’s the Life Expectancy of Your Commercial HVAC System?


Efficient heating and cooling systems are essential to the comfort of your building’s occupants and are also crucial to reaching and maintaining good indoor quality levels. Understanding the factors that affect the lifespan of your HVAC system can help you find ways to make it last longer.

Read on to learn more about the life expectancy of commercial HVAC systems.

The Lifespan of Commercial HVAC Systems

The life expectancy of HVAC systems varies by manufacturer, but most agree that the average is 15 to 25 years. However, a major factor that affects how long they last is proper maintenance. A well-maintained commercial HVAC system can even last for more than 25 years.

HVAC maintenance involves changing air filters, having a professional inspection performed yearly, addressing heating and air conditioning repairs and replacing worn components. Cleaning the air ducts and internal and external parts of the system is also part of the process.

A commercial HVAC system that’s not maintained can last for as little as five years. Even if you invested in a high-efficiency system, its performance will start to suffer and decline after its second year if not maintained.

Other Factors Affecting HVAC Lifespan

Certain kinds of air conditioners are designed to have a longer life than others. For example, some cooling systems use a two-stage mechanism that helps them last longer, as they aren’t exposed to constant on-off cycles. Moreover, a poorly-installed HVAC system is more prone to early failure and system breakdowns.

Like any equipment, heating and cooling systems age and wear down with use. Usually, the more you use your system, the faster it will experience wear. This is one reason why HVAC systems in extremely cold or hot places have shorter lifespans.
