What We Do

Our Building Automation System Services in Queens

Design, installation, and ongoing support for BAS platforms — giving Queens facility teams real control over comfort, energy, and compliance.

🖥️

BAS Design & Installation

We design and install DDC-based automation systems sized to your Queens building's mechanical plant — from single air handlers to multi-building campuses — with 75F, Honeywell, and Johnson Controls platforms.

🔄

Legacy Controls Retrofit & Integration

Pneumatic and end-of-life DDC systems are replaced or bridged into a modern BAS without ripping out working equipment, protecting your Queens building's capital investment while unlocking new functionality.

⚙️

DDC Programming & Sequence Tuning

We write and refine sequences of operation so your equipment actually runs the way it was designed to — optimized start/stop scheduling, economizer lockouts, and demand-controlled ventilation.

📡

Remote Monitoring & Fault Detection

24/7 remote alarm monitoring flags failing equipment before tenants notice, routing alerts to our dispatch team so a technician is on-site addressing the root cause, not just silencing an alarm.

🌿

LL97 Energy Optimization via BAS

NYC's Local Law 97 targets buildings over 25,000 sq ft — and a well-tuned BAS is one of the highest-leverage tools for reducing carbon exposure without capital equipment replacement.

📅

BAS Preventative Maintenance & Support

Scheduled system health checks, software updates, sensor calibration, and graphics maintenance keep your automation platform reliable and your Queens facility team confident in the data it's reporting.

LL97 Note: Queens buildings over 25,000 sq ft face escalating carbon penalties starting 2024. A properly tuned BAS is often the fastest, lowest-capital path to measurable emissions reduction — ask us about your building's exposure.

From tangled controls to tuned performance

One partner handles every step. Here's how we do it.

Site & systems assessment

A BAS engineer walks your Queens property, mapping every existing controller, sensor, and sequence to understand what's working, what's failing, and what's simply outdated.

Root cause diagnosis

We don't add new hardware until we understand why the current system underperforms — bad sensors, broken sequences, or a controls platform that was never properly commissioned.

Fixed-price proposal

You receive a clear, itemized scope and price before any programming begins — no hourly surprises, no scope creep billed after the fact.

Programming, commissioning & handoff

Our engineers program, test, and commission every sequence, then walk your facility team through the graphics and alarms so you're never dependent on us to understand your own building.

Questions we hear every day

Straight answers about building automation systems in Queens — no marketing fluff.

How quickly can Denair respond to a BAS failure or alarm storm in Queens?

Denair provides 24/7 emergency response across Queens with controls technicians typically on-site within 4 hours of your call. We monitor client BAS platforms remotely, so in many cases we're already aware of an issue and dispatching before you've picked up the phone.

Which building automation platforms does Denair work with?

Denair is factory-trained across 75F, Honeywell/Resideo, and Johnson Controls platforms, and we regularly integrate legacy pneumatic and DDC systems from other manufacturers into a modern BAS. We take a vendor-neutral approach — recommending the platform that fits your Queens building, not the one we happen to sell.

How does a building automation system help with NYC Local Law 97 compliance?

LL97 sets carbon emissions limits for NYC buildings over 25,000 sq ft, and HVAC operation is one of the largest drivers of a building's energy use. A properly tuned BAS enforces optimized schedules, setpoints, and economizer operation automatically — reducing energy waste without replacing equipment. Denair includes an LL97 impact assessment with every new BAS installation for qualifying Queens buildings.

What does a building automation system installation cost in Queens?

Pricing depends heavily on building size, number of points, existing infrastructure, and platform selection — a single air handler retrofit looks very different from a multi-building campus rollout. Denair provides a fixed-price proposal after a site assessment, with no hourly surprises once you've signed off.

Can Denair integrate a new BAS with our existing Queens building's legacy controls?

Yes — this is one of our most common projects. We assess your existing pneumatic or DDC infrastructure and design an integration path that preserves working equipment while modernizing the points that matter most, phased to fit your building's capital budget.
