Shapiro & Duncan Inc operates as a mechanical contractor serving Rockville and the broader Washington metropolitan area from a headquarters at 1 Research Court. The firm holds a 4.3-star rating compiled from 19 customer reviews, with operating hours extending from 7:30 AM through 4:30 PM on weekdays. Their portfolio demonstrates a specialized focus on large-scale commercial construction including healthcare facilities, educational institutions, government buildings, mission-critical operations, life science campuses, corporate offices, transportation infrastructure, and high-rise residential developments.
Rather than pursuing typical residential service calls, this contractor distinguishes itself through capabilities in virtual design construction and prefabrication workflows that compress field installation timelines. They maintain in-house engineering resources alongside specialized project divisions for HVAC controls and commercial service maintenance. Their workforce benefits from zero-dollar premium healthcare options among competitive compensation structures, reflecting an operational scale uncommon among regional contractors.
Customer feedback highlights multiple technicians by name. A reviewer credits Sid with rapid AC resolution and pleasant interaction during a service call. Another client notes Sid and Gus as consistently responsive and reliable for ongoing needs. A property manager at City Vista describes Richard as the dependable expert for HVAC and domestic hot water systems. One negative review mentions aggressive driving behavior by a truck driver, representing the sole one-star rating among reported experiences.
What Customers Say
Six of seven detailed reviews award five stars, citing specific technicians Sid, Gus, and Richard by name for responsiveness and reliability. Customer accounts reference successful servicing relationships spanning five to ten years. One isolated one-star review addresses driving conduct unrelated to service quality.
