What is a potential consequence of not maintaining HVAC systems properly?

When HVAC systems are not maintained properly, one of the primary consequences can be frequent equipment breakdowns. Regular maintenance, such as cleaning filters, checking refrigerant levels, and inspecting components, ensures that the system operates efficiently and effectively. When these practices are neglected, components can wear out faster or break down entirely due to stress and increased operational demands.

For example, a dirty filter can restrict airflow, causing the system to work harder than necessary, potentially leading to overheating and failure of critical parts like the compressor. Regular maintenance not only helps avoid disruptions in service but also extends the lifespan of the equipment by addressing potential issues before they escalate into significant failures.

In contrast, other choices such as increased indoor air quality or lower energy consumption are positive outcomes of proper maintenance, and improved system longevity can also be a result of regular attention to the equipment. Therefore, the focus on breakdown frequency underscores the importance of ongoing maintenance practices in keeping HVAC systems functioning smoothly.
