What is one way to enhance the efficiency of an HVAC system?

Regularly replacing air filters is essential for maintaining the efficiency of an HVAC system. Over time, air filters can become clogged with dust, pollen, and other debris, which restricts airflow. When airflow is limited, the system has to work harder to heat or cool the indoor space, causing it to consume more energy and reducing its overall efficiency. By ensuring that air filters are clean and replaced on a regular schedule, the system can operate at optimal performance levels, leading to improved energy efficiency, better air quality, and increased longevity of the HVAC components.

Increasing the outdoor air intake can lead to a higher load on the system, potentially resulting in reduced efficiency if not properly managed. Reducing the size of ductworks may cause airflow issues, as ducts need to be sized correctly to ensure adequate air distribution. Installing a smaller compressor can lead to insufficient cooling or heating capacity for the space, again hampering efficiency instead of enhancing it. Regularly replacing air filters is a straightforward, yet impactful maintenance practice that ensures the HVAC system operates effectively.
