Having serviced hundreds of commercial HVAC systems in the DFW climate, we've found that these units typically last 12–15 years with proper maintenance. That's shorter than the 15–20 year national average, since this part of Texas experiences extreme summer heat. If you don't commit to regular maintenance for your unit, it could fail in as little as 7–10 years. We've found that quarterly preventive maintenance can extend your HVAC system's lifespan by 25–40%.
