The old unit was placed there in 1989, and you can see by the exhaust marks that it was no longer running at high efficiency.
Fortunately, our location allowed easy access by a crane for loading and unloading. Note the skylights in the office area that let in ample natural light into the workplace.
The new units use a environmentally sound refrigerant of R-410A.
We hope that by bringing natural daylight openings into our building's design, and following enviornmatally sensitive operating methods, we can illustrate to others the benefits of thinking toward environmental and efficient design. We may even become a "leader" in the LEED field.
