What We Do

Our HVAC Controls Contractor Services in Brooklyn

Design, installation, integration, and ongoing support for the building automation systems that keep Brooklyn’s commercial HVAC efficient and code-ready.

⚙️

Building Automation System Design

We design BAS architecture around your existing equipment mix — whether that’s Carrier RTUs, VRF systems, or a legacy pneumatic system due for an upgrade.

📶

75F & Honeywell Controls Integration

Certified installation and integration of 75F and Honeywell/Resideo smart control platforms, unifying scheduling, zoning, and alarms across your Brooklyn portfolio.

🚨

Emergency Controls Support

A controls fault can take an entire building’s HVAC offline, not just one unit. Our technicians typically reach Brooklyn sites within 4 hours to restore control and scheduling.

🌿

LL97-Ready Energy Management

We configure demand-based scheduling, setback strategies, and real-time monitoring specifically to reduce the carbon exposure driving LL97 penalties.

📊

Remote Monitoring & Fault Alerts

Cloud-connected dashboards flag equipment faults before tenants notice, giving your team the data to act early instead of reacting to complaints.

🔄

Legacy System Retrofit & Upgrade

We migrate aging pneumatic or proprietary control systems to modern, open, and serviceable platforms — with NYC DOB filings and full commissioning included.

LL97 Note: Brooklyn buildings over 25,000 sq ft face escalating carbon penalties starting 2024. Smart controls with demand-based scheduling routinely cut HVAC energy use by up to 30% — one of the fastest, most measurable paths to reducing your building’s LL97 exposure. Ask us about your building’s exposure.

From site survey to smart building

One partner handles every step. Here’s how we design and deploy your controls system.

Building & equipment survey

A certified technician walks your Brooklyn property, documenting every zone, unit, and existing control point to build an accurate systems map.

Controls architecture design

We design a platform — 75F, Honeywell, or a hybrid approach — matched to your equipment, budget, and energy goals, not a one-size-fits-all package.

Fixed-price installation proposal

You receive a clear, itemized quote for hardware, integration, and commissioning before work begins — no hourly surprises.

Installation, commissioning & training

Certified technicians install and commission the system, then train your building staff on scheduling, alerts, and day-to-day operation.

Questions we hear every day

Straight answers about hvac controls contractor in Brooklyn — no marketing fluff.

How quickly can Denair respond if our Brooklyn building’s controls system fails?

Denair provides 24/7 emergency support across Brooklyn with technicians typically on-site within 4 hours. Because a controls failure can affect an entire building’s HVAC rather than a single unit, we prioritize these calls and carry diagnostic tools for both modern and legacy control platforms.

Which control platforms does Denair install and service?

Denair is a certified installer and service provider for 75F and Honeywell/Resideo building automation platforms, and we regularly integrate controls with Carrier, Trane, AAON, Daikin, Mitsubishi Electric VRF/VRV, and LG VRF equipment. We also service and gradually migrate legacy pneumatic and proprietary systems.

How do HVAC controls help with NYC Local Law 97 compliance?

LL97 sets carbon emissions limits for NYC buildings over 25,000 sq ft, and inefficient scheduling — running equipment at full capacity when it isn’t needed — is one of the largest avoidable sources of building emissions. Smart controls with demand-based scheduling and real-time monitoring routinely cut HVAC energy use by up to 30%. Denair includes an LL97 impact assessment with every new controls installation for qualifying Brooklyn buildings.

What does a controls system installation cost for a Brooklyn building?

Pricing depends on the number of zones, existing wiring condition, and platform selected, but every project is quoted as a fixed price before installation begins. Many buildings see the investment pay back within a few years through reduced energy costs alone.

Can Denair integrate new controls with our existing rooftop units and VRF systems?

Yes — Denair specializes in integrating 75F and Honeywell platforms with existing Carrier, Trane, Daikin, and Mitsubishi Electric VRF equipment, so you get unified scheduling and monitoring without replacing equipment that’s still performing well.
