Many homeowners believe that they need to replace their HVAC system every 10 years or so. However, this is a myth that Temperature Control, Inc. would like to debunk. With proper maintenance and care, your HVAC system can last much longer than a decade.

The Truth about HVAC Lifespan

  • A well-maintained HVAC system can last 15-20 years or more.
  • Regular maintenance, such as cleaning or replacing air filters, can extend the lifespan of your system.
  • Factors like usage, climate, and the quality of the initial installation also affect the lifespan.

Benefits of Keeping Your HVAC System

  1. Cost Savings: Replacing an HVAC system can be expensive, costing thousands of dollars.
  2. Energy Efficiency: Newer systems may be more energy-efficient, but proper maintenance can keep your existing system running efficiently.
  3. Environmental Impact: Replacing a functioning system contributes to waste and pollution.

When to Consider Replacement

While replacement may not be necessary every 10 years, there are instances when it might be the better option:

  • If your system is older than 20 years and requires frequent repairs.
  • If your energy bills are consistently high despite maintenance.
  • If your home’s heating and cooling needs have changed significantly.


At Temperature Control, Inc., we believe in maintaining and repairing existing HVAC systems whenever possible. Regular maintenance and timely repairs can extend the lifespan of your system, saving you money and reducing your environmental impact.
