One common problem is damage or wear to the system, such as damaged fans, damaged wiring, or faulty switches. Another major cause of reduced efficiency is faulty ductwork. Due to poor installation, damage or general wear and tear like holes and gaps may appear in the ductwork. This lets air escape, so less air reaches your living space.
