In this video segment, Derek Cole explains that HVAC systems rarely fail suddenly; instead, they typically exhibit warning signs before a complete breakdown. He identifies common early indicators such as dirty coils, clogged filters, and components that begin to weaken. As these issues develop, the system continues to run but works harder, leading to longer runtimes, reduced efficiency, higher energy bills, and diminished home comfort. If these signs are ignored, the system will eventually stop functioning entirely. Cole emphasizes that recognizing and addressing these warning signs through proper maintenance can prevent the final failure.

Systems don't usually stop working overnight. They can stop working overnight, but usually give warning signs. They usually have dirty coils or clogged filters or components start to weaken. The system itself still runs, but it's working harder, it's working longer, it's working less efficient. You start seeing higher energy bills, you start getting less comfort at home. You start getting longer runtimes until one day it finally stops running. It finally quits, and that can be prevented.
