The myth w/ higher SEER.

Many folks feel that by installing higher SEER (seasonal energy efficiency ratio (or rating)) equipment they will automatically see higher efficiency & lower utility costs. This could not be further from the truth if the system is not sized, designed, installed & maintained properly. An ideally installed 10-12 SEER system is more efficient than an oversized, poorly installed & never maintained 15-21 SEER system.

Systems need to per sized per each application, have proper ductwork design & installation, & be routinely serviced. Without those components, there is no efficient system.
