How do I get my employees motivated? How do I get the phones to ring more? How do I keep busy all year long and avoid the slow seasons? How do I make more profitable sales? Just about every service contractor complains about one or more of these issues, but they all can be eliminated with very little effort.
Now that the nation is finally showing signs of emerging from the worst recession since the 1930s, the latest long-range seasonal forecast from the National Weather Service indicates HVAC contractors may get some relief from the cold, hard times of the last couple of years with a hotter than normal summer in much of the country.
This article, reprinted from an EXHAUSTO white paper, discusses the benefits of demand-controlled ventilation (DCV) systems in multi-story, multi-residential buildings, which include improving building energy efficiency, enhancing comfort and other key performance factors. It reviews the application of DCV in new, retrofit and renovated building projects.
This job is a three-story office building with an air handler on each floor with a refrigerant coil in each air handler. A 75-ton condensing unit serves the three 25-ton air coils.

New York state homeowners now have an added incentive to install micro-combined heat and power (micro-CHP) systems. The New York State Public Service Commission approved tariff filings that pave the way for homeowners who install the systems to receive credit for excess electricity they generate and sell back to their utilities.
If a sheave is not balanced, it will have an inherent uneven distribution of weight. This uneven weight distribution magnifies vibration and noise when rotated and as speed of rotation increases. Unbalanced sheaves can also lead to premature life of other drive components due to the vibration and stresses placed on the components.

Among other things, the amended NDAA expands the number of employees who are eligible to take Family Medical Leave Act (FMLA) qualifying leave.

Facility managers are hunting for ways to operate more efficiently and conserve energy. We know more now than we did even a few years ago about where to look for unnecessary waste. We also know how to quantify the dollar value of that opportunity. That allows you to create a more accurate proposal that’s more likely to be approved and achieved.
In steam systems that have not been maintained for three to five years, between 15 percent to 30 percent of the installed steam traps may have failed - thus allowing live steam to escape into the condensate return system. In systems with a regularly scheduled maintenance program, leaking traps should account for less than 5 percent of the trap population.
Albert Einstein said that imagination is more important than knowledge. It’s obvious that the executives at Disneyland and Einstein are of the same mindset. That’s because at Disney, their imaginative minds created a promotion that is pure genius. It’s the “Give a Day, Get a Disney Day” celebration and it’s truly amazing!
