HVAC Testing & Balancing — Ulster County, NY

Ulster County stretches from the Hudson riverfront west into the Catskill Mountains — a large and varied territory whose HVAC TAB needs span acute care hospitals, public universities, industrial energy facilities, and the wave of Catskills resort development that has accelerated since 2020. Our Fishkill office sits 35-45 minutes from Kingston, Ulster's county seat, giving us reliable access throughout the county for the full range of testing, adjusting, and balancing work we perform.

Industries and facility types in Ulster County

Healthcare

HealthAlliance of the Hudson Valley — operating Benedictine Hospital and Kingston Hospital campuses, now within the Westchester Medical Center Health Network — is Ulster County's primary acute care system. The Benedictine campus in particular has undergone ongoing renovation and expansion, generating recurring TAB work. As with every hospital in our coverage area, we provide the Joint Commission-compliant pressurization documentation, room-by-room airflow readings, and outdoor air verification that healthcare specifications require. Ellenville Regional Hospital, in the county's southern tier, rounds out the acute care picture for communities west of the Shawangunks.

Higher education

SUNY New Paltz is a comprehensive four-year university with an active construction and renovation program. New York State University construction follows SUNY design guidelines and requires TAB documentation that satisfies both NYSED capital project review and NYSERDA energy code requirements. SUNY Ulster — a community college with campuses in Stone Ridge and Kingston — generates similar TAB work on a smaller scale. We have experience with the SUNY documentation format and the expectations of the state capital project oversight process.

Energy and industrial

Ulster County's industrial base includes utility infrastructure and specialty manufacturing. Energy facilities — including generation and transmission assets operated by Central Hudson Gas & Electric and others — require precision mechanical documentation for both new construction commissioning and ongoing operational verification. Industrial HVAC systems at this scale often involve process cooling, controlled-environment production areas, and complex exhaust systems that go well beyond standard commercial TAB. Our documented experience with industrial and energy facility work satisfies the specifications these clients require.

Catskills hospitality

The Catskills resort revival has brought significant new construction to the Ulster County area. Kartrite Resort and Indoor Waterpark — one of the largest indoor waterpark resorts in the Northeast — represents the complexity and scale of hospitality TAB work we handle in the region. Large resort facilities combine guest rooms, meeting and event spaces, food and beverage, and specialized recreational environments (pools, water features, spa) under a single roof, each with distinct ventilation requirements. We have the experience to balance and certify systems of this type and produce the commissioning documentation that resort operators and their engineers need for turnover.

Residential and new construction

Ulster County's residential market has expanded significantly as remote workers and second-home buyers have sought Catskills locations. New residential construction is subject to New York's IECC energy code, which triggers blower door and duct leakage testing requirements. We provide both through our residential testing program, serving Ulster County builders, homeowners, and energy auditors directly — and documenting compliance for NYSERDA incentive programs including the EmPower+ and Clean Heat initiatives.

Why Ulster County clients choose dL Flow Tech

The clearest answer is that NEBB-certified independent TAB is rare in the mid-Hudson Valley, and rarer still above Kingston. Contractors and engineers working in Ulster County have historically had to reach into the New York metro area for certified TAB — adding travel cost, scheduling friction, and a firm with no relationship with the local AHJ, the local utility, or the local construction community. We are a Hudson Valley firm first, with 40 years of relationships in this region. Our Fishkill location makes Ulster County efficient to serve, and our credentials make us the right choice for any job that requires NEBB certification.

Services available in Ulster County

Full TAB scope including air balancing, hydronic water balancing, duct leakage testing, blower door testing, commissioning, retro-commissioning, ventilation verification, fire and smoke damper testing, sound measurement, and LEED and energy code documentation. Residential blower door and duct leakage testing available throughout the county.
