What common maintenance task can extend the life of an HVAC system?

Regularly changing filters is a crucial maintenance task that can significantly extend the life of an HVAC system. When air filters become dirty or clogged, they restrict airflow and reduce the system's efficiency. This can lead to the system working harder to maintain the desired temperature, resulting in increased wear and tear on components, potential overheating, and higher energy costs. By changing the filters on a regular basis, you ensure that the airflow is unobstructed, allowing the system to operate more efficiently and reducing the likelihood of mechanical failures.

In contrast, skipping annual inspections can lead to unrevealed issues that, if left unchecked, can cause major problems down the line. Reducing system operating times might seem beneficial, but it's not a sustainable solution and doesn't address underlying inefficiencies. Using higher-grade refrigerant, while potentially beneficial in some contexts, does not directly influence the longevity of the system in the same immediate way that maintaining clean filters does. Regularly changing filters is a proactive approach that supports the overall health and efficiency of the HVAC system.
