Brooklyn Building Automation Company

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.

LL97 Note: Brooklyn buildings over 25,000 sq ft face escalating carbon penalties starting 2024. A properly tuned BAS is one of the highest-leverage ways to cut energy use without capital equipment spend — see our LL97 guide or ask us about your building's exposure.

Our Brooklyn BAS installation process

How Denair takes a Brooklyn property from controls audit to a fully automated, LL97-ready building.

01

Controls & equipment audit

A certified technician walks your Brooklyn property, documenting every mechanical system and existing control point to build an accurate automation plan.

02

Sequence of operations design

We design the control logic and integration points around your building's real occupancy and load profile — not a one-size-fits-all template.

03

Fixed-price proposal

You receive a clear, itemized quote for hardware, programming, and integration before any wiring begins. What we quote is what you pay.

04

Installation & commissioning

Certified technicians install, wire, and commission the system, verifying every point and sequence before handing over the dashboard.

Working In Brooklyn

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.

Brooklyn BAS & controls FAQ

Straight answers about building automation and HVAC controls installation in Brooklyn — no marketing fluff.

How quickly can Denair get a BAS project started in Brooklyn?
Denair can typically schedule an initial controls audit within a few business days of your call, with most straightforward Brooklyn commercial projects moving from audit to fixed-price proposal within one to two weeks. Emergency controls failures on existing BAS installations are handled same-day, with technicians on-site typically within 4 hours.
Is Denair certified to work with 75F, Honeywell, and Johnson Controls systems?
Yes. Denair's controls technicians are factory-trained on 75F, Honeywell/Resideo, and Johnson Controls platforms, along with the major RTU and VRF brands those controls typically integrate with. That means your BAS is programmed and commissioned to manufacturer specifications, not a generic install.
How does a BAS help with NYC Local Law 97 compliance?
LL97 sets carbon emissions limits for NYC buildings over 25,000 sq ft, and HVAC scheduling inefficiency is a major contributor to excess energy use. A properly tuned BAS applies optimized start/stop scheduling, setback strategies, and demand-based ventilation automatically — reducing energy draw without new mechanical equipment. Denair includes an LL97 impact estimate with every BAS design for qualifying Brooklyn buildings. Read our full Local Law 97 breakdown for filing deadlines and penalty tiers.
What does a BAS installation cost for a Brooklyn commercial building?
Pricing depends heavily on building size, the number of control points, and whether we're integrating with existing equipment or starting fresh — most Brooklyn commercial BAS projects range from a single-zone retrofit to a full building-wide rollout. We provide a fixed, itemized proposal after the initial site audit so there are no surprises once work begins.
Can Denair integrate a new BAS with our building's existing pneumatic controls?
In most cases, yes. We regularly integrate legacy pneumatic and early-generation DDC controls into a modern automation layer using transition modules and updated sensors, avoiding the cost of a full rip-and-replace. During the site audit we'll tell you plainly if full replacement is the better long-term option for your building.
