Humidification, Dehumidification + Mold: Page 1. THE HVACR CONTRACTOR’S WEEKLY NE WSMAGA ZINE SINCE 1926 August 6, 2012 | $5.00 | Visit us online at www.achrnews.com, Twitter, Facebook + LinkedIn SkillsUSA Draws Big HVACR Field By Peter Powell Of The NEWS Staff fyi hvac briefs K ANSAS CITY, Mo. — Who says young people do not want to be a part of the HVACR industry? Amidst the 5,600 vocationally-inclined individuals competing in 94 contests at the annual SkillsUSA National Leadership and Skills Conference, there were 58 in the HVACR event. That was the largest number ever to take part in the HVACR competition. They had come through local, state, and regional events to reach the national stage. They had committed to sometimes long travel to get to Kansas City, Mo., for five days of meetings and activities. Then they spent eight hours being tested in brazing, refrigerant recovery, and air measurement, as well as ser-vicing of air conditioning, heating, refrigera-tion, and geothermal equipment — all under the eyes of judges from the manufacturing, wholesaling, and trade association sectors. That day-long hands-on testing in Bartle Hall at the downtown Kansas City Convention Center was preceded by a written exam. Away from the actual competition, con-testants sat in on seminars, a number of which focused on soft skills in terms of cus-tomer relations and selling oneself, which were seen as valuable for those seeking to be • See SKILLSUSA | page 19 Price Increase • Lynxspring (Lee’s Summit, Mo.) announced a 3-5 percent price increase on their JENEsys product line, effective Sept. 1, 2012.

Taking Whole-House Approach to Battle Moisture, Mold By Herb Woerpel Of The NEWS Staff A s more and more homeowners be-gin to understand that controlling humidity is crucial to comfort, inter-est in humidification and dehumidi-fication solutions has continued to grow. Rick Tullis, president, Capstone Mechani-cal, Waco, Texas, said contractors should be aware of the factors that limit mold’s ability to multiply throughout an indoor environment. “We are surrounded by many types of molds and microbes, no matter how clean we keep our homes. Our best hope is to limit the growth of the mold and prevent it from setting up an active colony,” he said. “To do that, we need to do what any good military siege strategist would recommend, prevent the enemy, in our case mold, from getting the food and water it needs to flourish.” Tullis suggested contractors consider rec-ommending an effective filtration process during HVAC installation, to limit airborne dust that commonly serves as a food source for mold. “Those sources of food can be controlled; however other food sources may be more diffi-cult. In one case, a homeowner’s mold problem was due to their antique book collection and there wasn’t a good solution other than remove the books from the home,” he said. Speaking from experience, Tullis encour-ages contractors to examine plumbing and roof leaks, as well as air moisture. “In my own house, it took hard rain with strong southerly winds to expose a poor flashing installation from my roof when the house was built four years ago. I discovered the problem a few weeks later, as I found mold growing on the ceiling of the guest bed-room closet,” he said. “Additionally, a poorly installed, designed, or maintained mechanical system may offer a host of potential moisture pitfalls including gaps in piping insulation that may allow con-densation on the suction line, low discharge air temperatures, cracked drain pans, poorly • See WHOLE-HOUSE | page 11 A end this FREE Webinar!
