properties that run smart

Most BAS upgrades are phased floor-by-floor or system-by-system, so tenants and building operations continue normally throughout the project. Denair schedules controller swaps and points programming during low-occupancy windows whenever possible, and legacy equipment stays online until the new system is fully tested. For most Long Island City commercial buildings, disruption is limited to brief scheduled downtimes communicated well in advance.

In most cases, yes. Denair's technicians are trained across 75F, Honeywell/Resideo, Johnson Controls, and several legacy DDC platforms, so we can often integrate new points and sequences into your existing system rather than requiring a full replacement. If your current platform is truly at end-of-life, we'll tell you honestly and scope a realistic upgrade path instead of pushing an unnecessary rebuild.

LL97 penalizes buildings over 25,000 sq ft for excess carbon emissions, and HVAC operation is typically the largest emissions driver a building controls directly. A properly tuned BAS reduces unnecessary run-time, corrects sequencing errors that waste energy, and produces the real-time reporting data Long Island City building owners need for LL97 filings and audits. Denair includes an LL97 exposure review with every BAS project.

Cost depends heavily on building size, the number of points and sequences involved, and whether we're integrating with existing hardware or designing from scratch — a single-floor retro-commissioning project costs far less than a full multi-building DDC rollout. Denair provides a fixed, itemized proposal after the controls audit, so you know the full cost before committing, with no per-point change orders sprung on you later.

Denair remains your ongoing BAS partner after commissioning — monitoring alarms remotely, adjusting schedules seasonally, and dispatching a technician within hours if a controller or sensor fails. Because we designed and installed the system, our team already knows your Long Island City building's sequences, which means faster troubleshooting than starting fresh with an unfamiliar vendor.
