Claim This BusinessCrest Mechanical Services Inc has operated from Hartford, Connecticut since 1964, holding state HVAC license HTG.0391112-S1 alongside plumbing and fire protection licenses. The company maintains an A/EOE designation and earned Connecticut DAS Small Business Enterprise certification. Across 14 verified customer reviews, the contractor achieves a 4.3-star average rating, reflecting decades of consistent service to commercial facilities throughout the state.
This third-generation family-owned contractor distinguishes itself through bonded project capacity up to $12 million per job and a full-time safety officer, a rare investment among regional mechanical firms. Their credentials span five state-licensed trades under one roof: HVAC, sheet-metal fabrication, process piping, plumbing, and fire protection. Owner-partners combine 120+ years of mechanical construction experience, enabling value engineering during project estimates without sacrificing installation quality.
Reviewers consistently highlight fast response times and personable technicians. Tamaris Brandon, a construction professional, noted 'experienced technicians with great personalities and fast response time' following service. William Scalzo praised the owners directly, stating they 'taught me so much' about mechanical systems. The company offers same-day commercial service calls across Connecticut, and maintains a documented track record with 4 of the past 5 years receiving safety excellence awards from the Connecticut Association of Builders and Subcontractors.
Among 7 visible reviews, 5 award perfect 5-star ratings citing fast response, professional demeanor, and expertise. The sole 1-star review addresses an off-duty employee incident unrelated to service quality. The 4-star rating from Hank Cullinane reflects a typical positive but restrained assessment.
