The Evolution® 987M A unit with an AFUE of up to 97 percent is available in a new high-efficiency line of gas furnaces. The fully modulating gas furnace has load matching performance. A modulating gas valve is capable of adjusting from 40 to 100 percent of capacity.
When the U.S. government offered up to $1,500 in tax credits for higher efficiency appliances, HVAC contractors got their foot in the doors of consumers who might not normally have considered buying high-end. Since the tax credits were reduced in 2011, the same selling opportunities have dried up too — or have they?
The U.S. Department of Energy (DOE) announced that it has received the first official submission by a manufacturer to its voluntary challenge for a new generation of high-efficiency cost-effective air conditioners for commercial buildings.
The University of Texas Arlington has commissioned two new high-efficiency chillers that will serve the main campus cooling loop and provide projected annual energy savings of nearly $200,000.
We all create our own individual histories every day. At the same time, we become part of a larger history. With that in mind, we asked a few industry colleagues what the most significant changes were that they have witnessed in the HVACR industry.
The HVAC landscape is changing now, as the tax credits have been reduced, the economy is still recovering, and prices on equipment keep increasing. Add in declining home values and higher-than-normal levels of unemployment, and many contractors are facing larger challenges when it comes to selling high-efficiency units.
As HVAC products get more and more efficient, the logical question is what level will they top off at? The laws of physics can limit the efficiency levels of air-source heating and cooling equipment. The laws of economics also come into play, as the cost for each incremental escalation in efficiency can substantially increase the cost of the equipment.
This is a product round-up for new high-efficiency systems for light commercial and commercial applications. It highlights a variety of rooftop units and air handlers.
The NEWS’ annual Cooling Showcase has traditionally introduced the latest air conditioning units available for the upcoming summer season. The intent is to help contractors prepare for this busy period by doing the research that will help them to distinguish between brands. In this issue, we focus on the commercial side of the air conditioning industry.
