Historic Buildings


DW Collier Engineering, Inc. specializes  in design of replacement heating and cooling systems for historic buildings.  We will design a replacement system in accordance with current building and energy codes, obtain permits from all applicable state and local agencies, and provide fully engineered design documents for use in the selection of a licensed contractor to install the new system.  

We understand the attachment that can exist between a building and its owner.  We also understand how to provide a modern heating and cooling system within the constraints often presented by historic construction.  We deliver new systems designed around space and structural restrictions such that oftentimes you see no real evidence of the new system, except for the renewed reliability, new level of comfort, and reduced utility bills.
