The average lifespan of an HVAC system is 15-20 years. With proper maintenance, many homeowners can extend its lifespan to 20 years or more. Prolonging life expectancy can provide a better financial return as well as flexibility to shop around for a replacement as your unit nears the end of its lifecycle.

When to Repair and When to Replace

Prolonging the life of your HVAC system may make sense in the short-term, but consider the long-term effects of an aging system. There are technological advances in the heating and air conditioning industry every year. Within 10-15 years, more efficient systems will replace current models. Consider your average annual energy costs, maintenance costs, and new equipment costs to determine whether you should repair or replace your current model.

5 Tips to Improve Life Expectancy

Whether you decide to invest in a new system or need some extra time from an older model, these tips will help you get the most from your HVAC system:

  1. Invest in an annual tune-up. Maintenance is key to equipment longevity. Talk to your heating and air conditioning company about yearly maintenance programs. Draft a list of questions for your next service technician appointment. Service professionals often have additional tips for improving the performance of specific unit makes and models. With an annual tune-up, you can enjoy peace of mind.
  2. Follow recommended energy efficiency guidelines. An HVAC system that works hard throughout the year will wear out faster than one operating in an optimized environment. Invest in efficient insulation throughout your home. Repair ductwork leaks. Program your thermostat to automatically adjust for when you are home and away.
  3. Change air filters. Air filters not only improve air quality throughout a home, they enhance heating and air conditioning performance every cycle. Most equipment guidelines recommend changing the filter every four to six weeks. Environments with poor air quality (e.g., pollen, dust, other allergens) may require filter changes more often. If you have a reusable air filter, such as an electrostatic air filter, you may need to clean it once a month.
  4. Avoid closing doors and blocking air vents. Closing doors to unused rooms and blocking individual air vents may contribute to moisture and dust buildup within the system. Keep your home open for improved performance and proper air filtration.
  5. Monitor the outdoor portion of your system. Buildups of leaves, grass, snow, and pollen may force your unit to work harder to cool or heat your home. Brush off the outdoor system regularly. Inspect runoff pipes to prevent blockages and debris.
