What could be a potential consequence of neglecting HVAC system maintenance?

Neglecting HVAC system maintenance can lead to decreased system performance and efficiency because regular maintenance is essential for ensuring that all components of the system are functioning optimally. Over time, dirt, dust, and debris can accumulate in filters, coils, and other parts, obstructing airflow and causing the system to work harder to achieve the desired temperature. This increased workload not only diminishes efficiency but can also result in higher energy consumption and increased utility bills. Additionally, neglected maintenance can lead to wear and tear on essential components, ultimately reducing the system's overall effectiveness in providing heating and cooling, and potentially leading to breakdowns or costly repairs. Regular maintenance helps maintain the system's efficiency, prolongs its lifespan, and enhances its overall performance.
