A common issue we see in our Decatur service area during intense heat is air handler fan failure or strain on older systems. The sustained high temperatures can overload components, causing the system to struggle or shut down. Our service technicians are familiar with these local climate challenges. We can perform a thorough inspection, which may include checking refrigerant levels, cleaning coils, and testing the fan motor and capacitors, to diagnose the problem quickly. For commercial systems, we also offer preventative maintenance plans to help avoid these peak-season failures.
