"It was my pleasure to work with Des Crowley as an engineer on an unusual repurposing of a cold storage warehouse to a furniture store. Des was extremely helpful in surveying the building, establishing reasonable r-values for existing construction and working on the design of a suitable hvac system for the new use. He was able to take my schematic design to a design build spec with minimal assistance and the owner has been pleased with the installation and operation of this project. i would be most happy to work with Des again especially for his knowledge of current costs of hvac systems."
