What is the consequence of neglecting regular A/C maintenance?

Neglecting regular A/C maintenance can lead to higher utility bills and longer cooling times. This happens because when an air conditioning system is not properly maintained, its components can become less efficient. For instance, a dirty air filter can restrict airflow, forcing the system to work harder to provide the same level of cooling. This increased workload not only raises energy consumption, resulting in higher utility bills, but can also cause longer cooling times as the system struggles to reach the desired temperature.

In contrast, while increased noise levels during operation can occur due to mechanical issues that might arise from a lack of maintenance, this is not as direct a consequence as the impact on efficiency and costs. Saying that only the compressor experiences a shortened lifespan does not acknowledge the broader range of potential issues affecting the entire unit. Finally, neglecting maintenance does not lead to improved air quality; in fact, it often decreases air quality due to the buildup of dust and contaminants in the system.
