In this short video, Derek Cole explains that HVAC systems in the Sandhills region typically last 12–15 years due to the local heat and humidity. He notes that reaching the 10‑year mark is not early, but rather the point when homeowners should start evaluating maintenance or replacement options. Cole emphasizes that systems usually don’t fail abruptly; they first show gradual wear: reduced efficiency, lower airflow, higher energy bills, and longer run times. These symptoms often go unnoticed until a particularly hot summer day when the system appears to stop working.

Most systems last about 12 to 15 years here in the Sandhills in this climate with the heat and humidity. And if you're sitting at year 10, that's not early. You're right in the window of when you need to start looking at maintenance or replacement. And here's the truth most people don't hear. Most systems don't just break, they break down first. They wear down first. Efficiency drops, airflow drops, energy bills go up, run times get longer, and you don't even notice it until one hot summer day when the system seems to not be working.
