Commercial and residential HVAC, one licensed crew

Commercial VRF, ductwork, controls, split systems, and hydronic heating across Stratford and Fairfield County. Deep commercial capability, plus the residential work you expect.

Our differentiator

Commercial VRF, done by a true specialist

Most local HVAC shops stop at residential. Neftco is built around commercial variable refrigerant flow, the high-efficiency systems that run modern offices, retail, and mixed-use buildings. That commercial depth raises the standard on every job we touch, residential included.

Whether you need a ground-up VRF design, a retrofit of an aging system, or a heavy commercial duct installation, you are working with a contractor who does this work as a specialty, not a side line.

Commercial VRF Systems

Variable refrigerant flow is our specialty. VRF systems heat and cool many zones from a single efficient platform, with precise control and lower operating costs, which makes them ideal for offices, retail, and mixed-use buildings. We handle design, sizing, and clean installation, the depth of commercial capability most local shops do not advertise.

Because one outdoor unit can serve many indoor zones, a building can heat one area while cooling another, with each space on its own setpoint. That means lower energy bills, quieter operation, and tenants who stop fighting over the thermostat. We assess the building, run the load calculations, and spec the system so it performs for the long haul.

Best for: commercial buildings, multi-zone spaces, retrofits, and anyone who wants tight control and lower energy bills.

Split System Install & Repair

Ducted and ductless split systems sized and placed for real comfort in every room. We install new systems clean and to spec, and we troubleshoot and repair existing systems fast when they stop performing. Straight diagnosis, fair pricing, and work that holds up.

Common work: new mini-split installs, system replacements, refrigerant and compressor repair, no-cool and no-heat calls.

HVAC Automation & Controls

Modern controls and building automation that keep temperatures exactly where you want them and cut wasted energy. We set up smart thermostats, zoning, and commercial control systems so your HVAC runs efficiently and gives you visibility into how it performs.

Includes: smart controls, zoning, building automation integration, and scheduling for commercial sites.

Ductwork

Airflow is what makes a system actually deliver comfort. We design, fabricate, and install custom ductwork, then seal and balance it so conditioned air reaches every space, not just the room with the thermostat. Done right, it lowers bills and evens out hot and cold spots.

We handle: new duct design, replacement, sealing, balancing, and airflow correction.

Heavy Commercial Ductwork

Large-scale ductwork for commercial and industrial buildings, engineered for high volume and built to code. From restaurants and warehouses to large retail, we fabricate and install duct systems that handle demanding loads and keep big spaces properly conditioned.

Best for: warehouses, restaurants, retail buildouts, and high-capacity commercial facilities.

Hydronic Heating

Water-based heating delivers quiet, even, efficient warmth that forced air cannot match. We design and install hydronic systems for homes and commercial spaces that want steady comfort and lower heating costs, with proper layout and controls so every zone holds its temperature.

Good for: even whole-building warmth, radiant applications, and high-efficiency heating projects.
