Ruled by Regulation

摘要

Demanding regulations and evolving environmental protocols continue challenging the HVAC industry. After the push for 13-SEER products went into effect in January 2006, the U.S. HVAC industry began cooling off in terms of annual unit shipments. Shipments aren't looking up for 2007 either. Numbers for unitary air-conditioners for the first six months of the year totaled just 2.6 million, or about 13.4% lower than the previous year. The natural recession of shipments after the 13-SEER surge was exacerbated by the slowdown in U.S. housing sales.
