Customer Showcase

Commercial HVAC Project Showcase — Design-Build Solutions Across CT & RI

What You’ll Find in Our Project Portfolio

For over 40 years, Controlled Air has been engineering, installing, and servicing complex commercial HVAC and energy systems for facility owners, property managers, and general contractors throughout Connecticut and Rhode Island. This showcase represents a cross-section of that work — real projects, real clients, and real results.

Each project in our portfolio reflects our design-build approach: we don’t just install equipment, we evaluate your building’s needs, engineer the right solution, manage the installation, and stand behind the result with ongoing service and maintenance. Whether it’s a full mechanical system replacement, a high-efficiency cogeneration install, or a building automation upgrade, our team handles every phase in-house.

Types of Projects You’ll See Here

Our commercial HVAC project portfolio spans a wide range of system types and building categories across Connecticut:

Energy & Cogeneration Systems — Combined heat and power (CHP) installations, gas heat pump systems, and microgrid projects for schools, recreation centers, YMCAs, and commercial facilities. These projects deliver measurable reductions in energy costs and carbon footprint.

Rooftop Unit (RTU) Replacement & Installation — Commercial rooftop unit replacements for hospitals, office buildings, retail facilities, and breweries. We work with leading manufacturers including AAON, Carrier, Trane, and Lennox to specify and install the right equipment for each application.

Boiler Replacement & Hydronic Heating — High-efficiency boiler replacements and hydronic heating upgrades for schools, senior living facilities, and large commercial buildings. Brands include Lochinvar, Weil-McLain, and PK Boiler.

Chiller & Cooling Tower Installation — Chiller plant design and installation for healthcare facilities, industrial manufacturers, and large commercial office buildings.

Building Automation & Controls Upgrades — Johnson Controls and ABB building management system (BMS) installations for libraries, office campuses, and multi-use facilities. Smart controls that reduce energy waste and give facility managers real-time visibility.

Specialty & Custom HVAC Solutions — From ductless split systems in historic buildings to precision air handling for hospital histology labs, pharmaceutical environments, and biotech facilities — we solve complex problems other contractors won’t take on.

Facilities & Industries We’ve Served

Our project experience spans virtually every commercial building category, including:
Hospitals and outpatient medical centers · K–12 schools and higher education · Recreation centers and aquatic facilities · YMCAs and community centers · Bioscience and pharmaceutical labs · Manufacturing and industrial plants · Arenas and large public venues · Breweries and food production facilities · Office buildings and corporate campuses · Senior living and multi-family residential · Libraries and municipal buildings · Museums and cultural institutions

This breadth of experience means that whatever your facility type or project complexity, Controlled Air has likely done something similar — and done it well.

Working With Us

Every project in this portfolio started the same way: with a conversation. If you’re a facility manager, property owner, or general contractor in Connecticut or Rhode Island evaluating your options for a commercial HVAC project — a system replacement, an energy efficiency upgrade, or a new design-build installation — we’d welcome the opportunity to discuss your needs.

Our process is straightforward: speak with a sales engineer, schedule a walkthrough, receive a detailed quote. From there, a dedicated project manager guides your project from equipment procurement through final commissioning.

We’re licensed in Connecticut (CT S1 302788) and Rhode Island (RI R/M1 & P/M 00007776) and have served the region since 1980.
