Rats pose a significant threat to HVAC (Heating, Ventilation, and Air Conditioning) systems due to their damaging behaviors. These pests can cause extensive harm, including chewing on wires and insulation within the system. This compromises the electrical integrity and insulation effectiveness, increasing the risk of malfunctions, short circuits, and even fires. Rats’ nesting tendencies obstruct airflow and reduce the system’s efficiency, impacting temperature control and increasing energy consumption. Additionally, their presence introduces contaminants like droppings, urine, and fur, which compromise indoor air quality and can spread pathogens. Rats may also burrow through vents and ducts, further hampering air circulation and distribution.
