What is a routine maintenance task for improving HVAC efficiency?

• A. Cleaning the outdoor unit
• B. Regularly replacing or cleaning air filters
• C. Insulating the ductwork
• D. Adjusting thermostat settings

Answer: (B)

Regularly replacing or cleaning air filters is a fundamental routine maintenance task that significantly influences HVAC efficiency. Air filters trap dust, dirt, allergens, and other particles to improve indoor air quality and ensure that air flows freely through the system. When filters become clogged, they restrict airflow, which forces the HVAC system to work harder to maintain the desired indoor temperature. This increased strain can lead to higher energy consumption, reduced system lifespan, and an increased likelihood of breakdowns or inefficiencies. Therefore, maintaining clean filters not only enhances energy efficiency but also supports the overall performance and longevity of the HVAC system.
