Why Greencastle businesses call us
One contractor covers the whole building. The rooftop units, the walk-in cooler, the kitchen line, and the ductwork that ties them together all come from the same company, fabricated in our own sheet metal shop. When something fails you make one call instead of three, and nobody argues about whose equipment it is.
We are the longest-tenured York dealer in the world, and we have been doing this from the same Hagerstown address since 1932. That matters in Greencastle because the buildings we service, we often installed.
