Brooklyn's building
automation contractor
for smarter,
LL97-ready buildings
Denair is a Brooklyn HVAC controls contractor specializing in building automation system (BAS) design, temperature controls installation, and energy management for brownstone conversions and mixed-use commercial properties. One dashboard, full visibility into your energy use and LL97 carbon exposure.

HVAC Controls & Temperature Automation for Brooklyn Properties
As a Brooklyn building automation company, Denair handles the full scope — BAS design, temperature controls installation, legacy system integration, and energy management software — matched to how Brooklyn's commercial buildings actually operate.
Building Automation System Installation
We design a BAS around your existing mechanical equipment, then install and wire it to spec — no rip-and-replace required in most Brooklyn buildings. Also serving Queens and Long Island City.
Temperature Controls Installation
Zone-by-zone thermostat and setpoint control programmed to your building's real occupancy and load patterns — see our dedicated temperature controls installation Brooklyn page for details.
Legacy Controls & BMS Integration
Many Brooklyn buildings run a mix of pneumatic, DDC, and newer smart controls. We integrate them into a single automation layer instead of forcing a costly full swap.
Building Energy Management Software
Real-time visibility into every zone's temperature, airflow, and energy draw — accessible from a single energy management dashboard your facility team can actually use.
LL97 Compliance via Automated Scheduling
Automated scheduling and setback strategies are among the fastest ways to cut a Brooklyn building's carbon output. Read more on Local Law 97 compliance.
HVAC Controls Support & Monitoring
Remote monitoring catches drift and faults before they become comfort complaints, with a certified Brooklyn HVAC controls contractor technician a call away.

A Building Automation Contractor for Brooklyn's Older Building Stock
Brooklyn's commercial building stock is unlike any other borough we serve. Converted brownstones and mixed-use retail-residential buildings in neighborhoods like Park Slope and Bed-Stuy often carry decades-old pneumatic controls stacked awkwardly alongside newer rooftop units added during later renovations — a mismatch that makes HVAC controls integration more of a puzzle than a clean install. Further south and east, industrial-to-loft conversions in Gowanus, Bushwick, and Sunset Park present a different challenge: high ceilings, exposed ductwork, and mechanical rooms that were never designed with a controls platform in mind.
That mix is exactly where a properly engineered building automation system earns its keep. In a Brooklyn brownstone conversion, for example, we typically find several small, disconnected control zones — one per unit or floor — that a unified BAS can bring under one schedule without re-running conduit through finished walls. In a converted industrial space, the win usually comes from tying make-up air units and exhaust fans into the same automation layer as the rooftop units, since those systems are often installed years apart by different contractors and never talk to each other. See our temperature controls installation options for a lighter-touch starting point.
Our Brooklyn service coverage runs from Sunset Park and Bay Ridge in the south to Greenpoint and Williamsburg in the north, with technicians dispatched from our Bensonhurst office — typically the shortest response radius of any borough we serve.
