If duct cleaners want to grow their business, it’s all about alliances. That was the bottom line from two separate sessions at the 2007 National Air Duct Cleaners Association (NADCA) meeting and exposition.
It’s not surprising that coil restoration was one of the technical topics discussed in length at the 2007 National Air Duct Cleaners Association (NADCA) meeting and exposition. What surprised most attendees was the topic from keynote speaker Bob Davis of Wilson Learning, who zeroed in on the ins and outs of human behavior.
Heat reclaim can be accomplished with either a series or parallel method. In the series approach, when a finned tube heat exchanger is used it is properly termed a heat reclaim coil.
Contractors rode much the same roller coaster that manufacturers and distributors did in 2006. The ever-changing HVAC industry and the multiple factors that affect it brought instability to the arena as contractors adapted to the challenges. The HVAC contractor market primarily mirrored 2006’s construction market. Residential HVAC experienced an expected cooling-off period, but commercial HVAC continued its three-year climb.
Johnson Controls Inc. sold Bristol Compressors Inc. to KPS Capital Partners LP, a private equity firm. Financial terms of the transaction were not disclosed.
On the way to designing the HVAC systems for the new Wynn Las Vegas Hotel, the project’s consulting engineer, architect, and mechanical contractor were confronted with fierce rain storms, rings of fire, and cannon balls of water - without leaving their offices.
The bulge in the supply chain eased in 2006 as distributors adeptly addressed the inventory bottleneck that resulted from the mandatory changes in SEER minimums. Overall, 2006 shipments were down 7.5 percent as compared to 2005.
The gauntlet was thrown down and the challenge was met as HVAC manufacturers took on their biggest test of 2006: Mandated 13 SEER implementation. Although prepared for an intense journey, situations arose throughout 2006 that left this facet of the HVAC industry digging deep to find the solutions.
A lot of people who work on HVAC systems outdoors seem to dismiss the risks associated with their own exposure to contaminants from birds, specifically “pest” birds (wild pigeons, starlings, sparrows, and seagulls). They could be exposing themselves to potentially serious health risks.
Staying safe requires vigilance and the proper tools. Carelessness can be overridden with appropriate training and proper management; however, it also takes the correct tools to reduce the risk of worker injury. The Mack Rack and Kart System is a rack and a cart combined, designed to ease the lifting and transporting of large, heavy objects.
