Package and split rooftop air conditioning systems are the workhorses of the heating, venting, and air conditioning world. These heating, ventilation, air conditioning, and cooling (HVAC) units are smaller and relatively less costly than large chiller plants, so building owners tend to ignore them, but poor maintenance comes at a price. Systems that are not properly inspected and serviced run harder and less efficiently than they should. This means added power and peak-load costs for the building owner.  G&B Environmental, Inc has tools that measure and verify these kind of conditions and can report this information to the manager to make cost-effective maintenance decisions that will help improve the bottom line.  Calln 1-800-466-2018n for more information or visitn www.gbenvironmental.comn
