Excellent service begins by listening to your building. Each has its own distinctive sounds and warnings, and no two environments are alike. We let the building speak, then provide a remedy. City Mechanical has mastered the art of writing in-depth proposals in which complex issues are explained in simple language. Our diagnosis can include a scope of work, equipment and maintenance demands, upgrades for historic buildings, and knowledge of current codes and LEED certifications. All of this is explained in detail before we lay a hand on your eco-system allowing you to make choices with confidence.
