Life Cycle of HVAC Systems: How Long Do They Last?

Heating, ventilation, and air conditioning (HVAC) systems can last for a significant duration. To get the best value out of your unit, you need to become aware of the most common factors that affect their life cycle. When HVAC systems reach the end of their lifespan, it’s highly advisable to have them replaced rather than spend an endless routine of repairs and costly maintenance services to extend its functionality. Habitual malfunctions often indicate that your unit is about to retire, and it’s probably causing a high influx rate on your electricity bills. So, let’s go ahead and jump over it!

How long do HVAC units last?

There are different kinds of HVAC units. We’ll discuss each of their functions and their expected life cycle.  

Air Conditioner

Air conditioners are central heating and air systems that require occasional maintenance and regular cleaning. The part that you need to keep an eye on in an air conditioner unit is the compressor.  When it starts showing fluctuating failures, it either suggests a major repair or unit replacement. They usually last for an average of 15 to 20 years. However, frequent usage of air conditioners, especially in warm regions, will probably limit the lifespan of the system for only up to 15 years.


Furnaces also function as central heating and air systems with an average lifespan of 20 years, which is quite longer than air conditioners. Typically, furnace units demand standard maintenance methods to make them last as long as they should. The most important feature of furnaces is the heat exchanger. Once this function starts breaking down, you’re better off buying a new furnace than having your old unit repaired.  

Heat Pump

Heat pumps can function as a heating or cooling system. They can last for as short as 10 years, but their life cycle can be extended for 20 years. Based on experience, they often fall out quicker than air conditioners, particularly when used in areas bordering the water.  


Boilers are fuel-powered heating systems most suitable for places with harsh cold weather. They’re designed with old-school technology, but long as the heat exchanger remains working, they can last 20 to 35 years.  

Spit System

Split systems work like central heating and air conditioning for all kinds of weather. They can also serve as a pollutant or allergen prevention unit because it’s equipped with a filtration system. Constant use in coastal areas might cause split systems to last for only as short as 10 years. However, they’re initially designed to function for up to 30 years.  


Two primary factors that affect HVAC systems’ lifespan are (1) the frequency of usage and (2) amount of maintenance methods applied during their functional years. If you wish to extend your HVAC system’s life cycle, you need to invest in regular maintenance methods. By doing this, you can always keep efficiency at an optimal level.
