No one can predict with 100% certainty the exact life expectancy of your HVAC system. So, how will you know it is time to replace an old heating and cooling system in your home? Well, you can use the following average lifespans of the different HVAC systems to estimate the life expectancy of yours:

Air Conditioners and Heat Pumps: 10 to 20 Years

Most air conditioners and heat pumps last for between 15 to 20 years. However, if you reside in a coastal area, the lifespan tends to be much shorter due to slat exposure. Depending on usage frequency, heat pumps can last one or two decades. Both air conditioners and heat pumps are replaced once the compressor fails. You should also plan for replacement when the condenser develops leaks and corrosion.

Furnaces: 15 to 20 Years

With proper maintenance, gas furnaces can last for a maximum of 30 years. You should replace the furnace once the heat exchanger starts leaking. Furnace systems that are poorly maintained may not last more than ten years.

Boilers: 20 to 35 years

Boilers tend to last longer than furnaces. If you properly maintain your unit, expect it to last for up to 35 years. Typical maintenance practice involves the replacement of heat exchanger once it starts to leak.

Ductless Mini-Splits: 10 to 30 years

Except in coastal regions, ductless mini pumps can enjoy a lifespan of between 10 to 30 years, depending on usage frequency. Ideally, these units provide both heating and cooling functionalities and are used for an extended period each day.

Pro tip: If you are looking to extend your HVAC system’s lifespan, strive to maintain your units regularly. Even with proper usage and maintenance, strive to replace your HVAC system sooner. As the system ages, it will gradually become less reliable and efficient, increasing repair and utility costs.

What Does Regular Maintenance Involve?

If you are looking to extend the lifespan of your furnace, boiler, or heat pump, use the following maintenance tips:

  • Change filters regularly
  • Inspect and replace refrigerants routinely.
  • Clean and remove debris from external components.
  • Schedule annual or seasonal tune-ups

Should You Repair or Replace Your Faulty HVAC System?

Fix your HVAC system only if it has five or more years left in its expected lifespan. However, replace the system with a new one if the repair costs go beyond half the cost of a new one.
