What should be monitored regularly to ensure an HVAC system operates efficiently?

Monitoring the cleanliness of air filters and ductwork is essential for the efficient operation of an HVAC system. Dirty air filters can restrict airflow, making the system work harder to achieve the desired temperature, which can lead to increased energy consumption and potential system failure. Additionally, accumulated dirt and debris in the ductwork can restrict airflow and impact indoor air quality, further stressing the HVAC equipment. Regular inspections and maintenance of both air filters and ductwork help to ensure optimal airflow, enhance system efficiency, and prolong the lifespan of the HVAC system, ultimately fostering a healthier indoor environment. In contrast, focusing only on temperature settings or the aesthetic qualities of the system does not directly ensure its efficient operation, and while the type of refrigerant is important, it is not something that typically requires routine monitoring for efficiency.
