Eby Construction made the decision to move into a new corporate office and renovate an office, warehouse, and shop area. Because Dean E. Norris, Inc. has partnered with Eby on many projects, Eby selected Dean E. Norris, Inc. to complete their mechanical system construction  utilizing the design-build approach. The two 22,000 square-foot pre-engineered metal buildings had dated, inefficient mechanical equipment. Dean E. Norris, Inc. installed a Mitsubishi Variable Refrigerant Flow (VRF) system and energy recovery ventilation (ERV) in the office. A VRF system has many advantages of installation which include: Energy Efficiency Ultra Quiet Operations Aesthetics Lower Lifecycle Cost Safety Zoned Comfort (The individual can control the space to their comfort. The office space has over twenty zones.) We also installed new piping and plumbing throughout the two buildings. New plumbing...
