How Long Will HVAC Systems Last

How Long Will HVAC Systems Last
  • Opening Intro -

    A HVAC system is a significant investment and you need to get as much use of it during its lifespan.

    Generally, HVAC systems can last as long as 15 or 25 years but there are many factors that might affect the lifespan.


Factors Affecting HVAC Lifespan

Some of the factors that are likely to reduce the lifespan of your HVAC system include the following

  • 1) Poor or lack of maintenance which accelerates the wear and tear of the system leading to a shorter lifespan of your HVAC system.
  • 2) Improper usage of the HVAC system such as heating or cooling when the doors or windows are open.
  • 3) Poor installation procedures resulting in poor functionality of the entire system.
  • 4) Poor initial quality or defective components
  • 5) Installation of the HVAC system in corrosive or salty areas such as in the coastal areas.

Typical HVAC Lifespans

The lifespan of an HVAC system mostly depends on the type. Here are some of the known lifespans for common HVAC equipment.

  • 1. Boilers –

    They have a longer lifespan than furnaces and can last as long as 20 to 35 years. You should replace your boiler if you notice the heat exchanger is leaking.

  • 2. Furnace –

    With proper maintenance, gas furnaces can last as long as 20 or 30 years. It should also be replaced when the heat exchanger starts leaking since it’s the most critical and expensive components. Poorly maintained systems or those of questionable quality may last for 10 years. Oil furnaces only last for 10 to 15 years because of the maintenance problem often caused by inefficient fuel.

  • 3. Air Conditioners –

    Most air conditioners last for 15 to 20 years but some have a lifespan of 10 years. If the HVAC system is installed in the coastal areas, the AC might last for 7 to 12 years due to salt exposure. You should replace the air conditioners and heat pumps when the compressor fails or if there any leaks or corrosion on the condenser.

  • 4. Heat Pumps –

    They can last for 10 to 20 years depending on how frequent they are used. The average lifespan is 15 years. Heat pumps usually have the same function as air conditioners. However, they provide both cooling and heating functions so they are usually used for longer periods. In the coastal areas, heat pumps are likely to fail prematurely and have a lifespan of 7 to 12 years.

  • 5. Ductless Mini Splits –

    Similar to the heat pumps, ductless mini splits also provide both cooling and heating functions. They have a typical lifespan of 10 to 30 years but it’s shorter in the coastal areas.

other valuable tips:

Note that, these might be the typical lifespans of different HVAC equipment but many homeowners often replace their HVAC system sooner. The system is bound to become less reliable and efficient with age. Eventually, there will be a notable increase in utility and repair costs.

If your system is already 10 or 15 years old, upgrading to a newer and more efficient model can save a lot of utility costs effortlessly.
