The phrase “out of sight, out of mind” may as cliché as the day is long, but when HVAC contractors were asked to share their maintenance tips for rooftop units, the overused expression popped up again and again as they described how most building owners treat their rooftop HVAC equipment.

With the price of photovoltaic (PV) panels falling rapidly, utilizing solar energy has suddenly become a cost-effective choice for many large retailers, who are now embracing the technology with open arms.

The new Carrier WeatherExpert 10-ton unit exceeds the parameters of the recent U.S. Department of Energy (DOE) Rooftop Unit (RTU) challenge, the company announced.

The project goal was to update HVAC equipment for a 17,000-square-foot research facility within the university's 800,000-square-foot medical center north building on its Nashville, Tenn., campus. 

It’s time again for the annual Cooling Showcase. The intent is to help contractors prepare for this busy period by doing the research that will help them distinguish between brands.

With building owners and managers looking to wring savings from every square foot of space, manufacturers have introduced a wide array of advanced energy-efficient technologies that are designed to lower utility bills without compromising comfort.
