What can result from a lack of regular preventive maintenance in HVAC systems?

A lack of regular preventive maintenance in HVAC systems can indeed lead to reduced system longevity. Preventive maintenance is essential for ensuring that all components of the HVAC system are functioning optimally and efficiently. When maintenance is neglected, various issues can accumulate over time, such as dirt build-up, worn-out parts, refrigerant leaks, and electrical problems.

These issues can significantly strain the system, leading to increased wear and tear on components like compressors, fans, and coils. Consequently, this can cause parts to fail prematurely, shortening the overall lifespan of the system. Regular maintenance helps to identify and address these issues before they escalate, which ultimately prolongs the life of the HVAC equipment and reduces the need for costly repairs or premature replacement.

In contrast, while other options might seem beneficial or desirable outcomes, they would typically not occur as a result of neglecting maintenance. For example, the reliability of the system would likely decrease, energy consumption could increase due to inefficiencies, and air quality might deteriorate as filters and ventilations are not properly maintained.
