COMMERCIAL HVAC
VRF, chilled water, rooftop, and high-purity air systems engineered for facilities that can't go down.
Advanced Sheetmetal & Mechanical designs, fabricates, and installs commercial HVAC systems across Connecticut for owners and general contractors who can't afford a system that "mostly works." Our crews work in laboratories, healthcare, cleanrooms, and other critical environments where pressurization, filtration, and temperature stability are non-negotiable.
We integrate sheetmetal fabrication, piping, and controls coordination under one roof, which removes most of the handoff risk that drives change orders and schedule slips on mechanical jobs.
Multi-zone Mitsubishi, Daikin, and LG VRF design-build for office fit-outs, healthcare suites, and adaptive reuse.
Air- and water-cooled chillers, pumping packages, glycol loops, and primary/secondary distribution.
RTU replacements, custom AHU installs, and 100% outside air units for labs and isolation suites.
Pressurization cascades, HEPA terminal housings, fume hood exhaust, and stainless duct for high-purity environments.
Boilers, heat exchangers, hot/chilled water reset, and steam to coil/process loads.
We coordinate directly with your BAS contractor and CxA to make sure sequences, sensors, and trims match design intent.
Most of our HVAC work lands inside facilities where downtime carries real cost, like interrupted research, lost batches, or patient impact. We plan tie-ins, shutdowns, and phasing around your operations, not around our convenience.
Yes. Our duct shop and pipe crews are in-house, which lets us prefab to BIM, hold tight schedules, and avoid relying on third parties for critical work.
Single-room renovations through multi-million-dollar facility builds. The common thread is critical-environment requirements in labs, healthcare, cleanrooms, and process spaces.
Our installation crews primarily work the eastern two-thirds of CT, and we can support service calls statewide.
The earlier we're on a project, the more we can value-engineer, prefabricate, and de-risk the install. Let's talk specs, timeline, and budget.
Variable refrigerant flow design-build for commercial fit-outs.
Central plants, distribution, and lab process cooling.
RTU installs, replacements, and custom AHUs.
ISO classed environments and pressurization.
Research and analytical lab HVAC.
Keep installed systems performing.
