HVAC System Life Expectancy & Tips for Maintaining Performance

Posted on May 17th, 2015 by carrolladmin

Recent research indicates the average life expectancies of various HVAC equipment tends to linger around the same ranges.   However, each system has unique characteristics that may lend to fluctuations in life expectancy.  Regardless of age, regular preventative and seasonal maintenance as well as the quality of installation play an important role in determining lifespan.  Here’s a general breakdown of the average lifespan for some of the most common HVAC system components:

Air Conditioning Unit: up to 15 years

Outdoor Air Compressor: up to 15 years

Heat Pump: 10-15 years

Gas & Oil Furnaces: 15-20 years

Boiler: 30-40 years

Electric Baseboard Unit: up to 20 years

Mini Split: 12-15 years

Your HVAC system is likely both the most expensive system, as well as the one that uses the most energy in your home. Data published by the Department of Energy estimates that nearly ½ of your home’s yearly energy consumption is strictly attributed to keeping it cool and warm.  Whether your system is a recent upgrade or the home’s original system, there are some things you can do to help your equipment last longer and run more efficiently.  Consider these tips to extend your HVAC system life expectancy…

  • Regularly change the air filter
  • Clean the outdoor condenser
  • Use a programmable thermostat
  • Avoid closing off heat and air registers in unused rooms
  • Run the attic fan periodically during cooling season
  • Invest in preventative maintenance and seasonal system tune-ups


HVAC technology has come a long way.  While many of the homes in our area are equipped with traditional, basic HVAC systems and components, there are some new technologies available for those wanting to upgrade.  Hybrid systems and radiant systems are two of the newer, more popular energy efficient HVAC technologies.  Solar systems are gaining momentum, but have yet to take off as expected in years to come.
