HVAC Controls, Retrofits & Temperature Automation for LIC
As a Long Island City building automation company, Denair handles the full scope — BAS design, legacy system retrofit, temperature controls installation, and energy management software — matched to LIC's fast-changing commercial and industrial building stock.
Building Automation System Installation
We engineer a controls architecture around your building's actual equipment mix and occupancy patterns, then install and commission a system built to run for decades. See building automation in Queens for our neighboring coverage.
Legacy Controls & Building Management System Retrofit
Replacing an aging or unsupported BAS platform with 75F, Honeywell, or Johnson Controls hardware — without ripping out working field devices unnecessarily.
Remote Monitoring & Fault Alarms
24/7 visibility into every zone, unit, and setpoint from a single dashboard, with automated alerts routed to your team before a fault becomes a comfort complaint.
Temperature Controls Installation
Demand-based scheduling and setback strategies tuned to Long Island City's actual occupancy hours, typically cutting HVAC energy spend by 15–30%.
LL97 Automated Compliance Reporting
Your BAS becomes your compliance engine — automated emissions and energy-use reporting formatted for NYC Local Law 97 filings, reducing manual tracking.
Preventative BAS Maintenance
Scheduled calibration, sensor verification, and software updates that keep your controls platform accurate and your building performing to spec year-round.

A Building Automation Contractor for LIC's Changing Skyline
Long Island City's building stock has shifted faster than almost any other NYC submarket. Former manufacturing and warehouse buildings along the waterfront and around Court Square have been converted into loft offices and residential towers, often retaining the original high-ceiling, open-floor mechanical layout while operating a completely different occupancy pattern than the building was ever designed for. Newer ground-up high-rises near the waterfront present the opposite problem: modern equipment that arrived pre-wired for a specific BAS platform, which then needs to be integrated or replaced as ownership or management changes.
That combination — legacy industrial shells carrying modern occupancy loads, and newer towers with platform-specific equipment — is where a properly scoped building automation system pays for itself fastest. In a converted loft building, we typically find oversized rooftop units still running on their original factory schedule, wasting significant energy outside business hours; tying that RTU into a modern BAS with occupancy-based scheduling is often the single biggest LL97 win available without touching the mechanical equipment itself. In newer towers, our work is more often about breaking vendor lock-in — integrating a proprietary BAS platform so building staff aren't stuck calling one manufacturer for every service call.
We cover Long Island City end to end, from the Queensboro Bridge waterfront through Court Square and into Sunnyside, with the same certified technicians who service our HVAC controls and temperature controls installation accounts across the neighborhood.
