Can the Everclean Green Force Field be used in existing older HVAC systems as well newly installed units?
Yes. The key for gaining system efficiency is to get 400 CFM per ton of airflow through the A/C. Currently, the nations 89-million HVAC systems average about 265 CFM — caused by starved airflow from dirty, restrictive filters, and loaded A/C coils. By keeping the coil clean and eliminating the restrictive filter, the system (old or newly installed) can get 400 CFM per ton, causing a big jump in energy efficiency on a continuous basis. With an adjustment in fan speed and refrigerant charge (lower for both), the system (old or new) can get a big drop in energy use, perhaps up to 35% less energy needed.
