That depends on whether you're using a fixed bar return grille or a stamped face grille. In our opinion, the fixed bar return grille (also known as a high-flow return grille) will give you more bang for your buck. This is because the louvers are positioned further apart to allow for more air to pass through the grille, making a fixed bar return grille more aerodynamic and energy-efficient than a stamped faced grille. Benefits include:
- A high-flow return grille produces less static pressure, which lowers energy bills and helps to prolong your HVAC system's lifespan.
- A correctly sized fixed bar return grille will reduce noise and facilitate optimum airflow throughout your home for health and comfort.
Furthermore, a dirty, damaged, or obstructed air filter grille can make an HVAC system work harder, which takes more energy and leads to higher costs. An overworked HVAC system can also lead to temperature irregularities and lower air quality.
For energy efficiency, ensure your air filter grilles are secure, clean, and undamaged. It’s also a good idea to replace your filters every thirty days to ensure optimum air quality and temperature comfort.
