There are many low cost alternatives available to companies to improve and extend the life of HVAC systems, motors and even lower maintenance cost at the same time. Quantifying savings that really requires no real decision. I have yet to sit across from someone, show them annual savings of thousands of dollars and R.O.I periods of less than 24 months that said "no, we're gonna wait and see". If, that ever happened, my guess is they won't be employed there very long and I will get in the door later. The point here is, take advantage of the commercial market, but do not approach it without being educated first. 411 Energy Experts has accredited CEA training available both on-line and live.
