have opted not to display their products at the Expo because of the high costs
involved and a questionable return on investment. But due to the particular
northeastern market, which is a valuable part of their business, even the
world’s largest HVAC manufacturer, Carrier Corp., had several of its top
commercial and residential products on display.
