The Severn Group

The Severn Group holds a 4.5-star rating drawn from 13 client reviews and operates as a commercial-focused HVAC contractor serving Upper Marlboro and the broader Washington D.C. metropolitan area. Since formally launching operations in 2002, the company has concentrated on complex mechanical and plumbing systems for commercial properties, institutional facilities, and new construction projects. Their service window covers Monday through Friday from 9 AM to 5 PM, with 24-hour emergency availability for contracted clients. The company maintains active specializations in chiller and cooling tower installations, boiler replacements, medical gas systems, and custom sheet metal ductwork, areas requiring specialized licensing and technical expertise beyond standard residential HVAC work.

What distinguishes The Severn Group from typical residential HVAC companies is their project delivery model capabilities and equipment expertise. The company handles negotiated contracts, design-build arrangements, mechanical-general contracting, and service repair or replacement projects. Their equipment portfolio includes chiller systems and cooling towers, components typically found in office buildings, data centers, and institutional complexes rather than single-family homes. Additionally, they install and service medical gas systems, positioning them uniquely for healthcare facility work in the Maryland market. Their blog addresses commercial-specific concerns including HVAC short cycling prevention, water conservation strategies in commercial plumbing systems, and comparing chilled water versus direct expansion cooling methods for commercial buildings, a technical depth uncommon among residential-focused contractors.

Several reviewers specifically mention receiving prompt, quality service during difficult situations. One client describes Steven Castillo delivering excellent service with rapid response time. Another review notes Kyle Gil earning a perfect 10-rating for their interaction. A Spanish-language review from Melvin Dubon simply states excellent service. However, one reviewer documented a significant contrast, M S reported receiving no callback or follow-up communication after an initial inquiry, representing a notable gap in customer service responsiveness that prospective clients should weigh against the overwhelmingly positive feedback.
