Building automation
and HVAC controls
contractor in Queens
for every equipment brand
From BAS integration to VFD retrofits, we design and install controls that work across your existing equipment — whatever the manufacturer. Centralized building automation cuts energy costs and builds the performance record LL97 compliance requires.
Our HVAC Controls Services in Queens
Building automation, controls integration, and VFD/temperature controls upgrades for Queens commercial buildings — designed to work across whatever equipment you already have installed.
Building Automation System (BAS) Integration
We design and install BAS platforms that unify scheduling, monitoring, and alarms across every mechanical system in your Queens building — regardless of equipment brand.
Temperature Controls Retrofits
Replace aging pneumatic or legacy thermostats with modern digital controls that give your team precise, zone-by-zone temperature management.
VFD Installation & Upgrades
Variable frequency drives on fans and pumps cut motor energy use significantly by matching output to actual demand instead of running at full speed continuously.
Legacy Controls Replacement
We integrate new controls with your existing Carrier, Daikin, Mitsubishi, LG, or other rooftop and VRF equipment — no need to replace equipment to modernize how it's controlled.
Remote Monitoring & Alarms
Get real-time alerts on equipment faults, temperature drift, or scheduling errors before they become tenant complaints or emergency calls.
LL97 Energy Performance Tracking
Centralized controls generate the ongoing energy usage data your building needs to document performance and reduce carbon exposure ahead of LL97 filing deadlines.
From equipment audit to full automation
One partner designs, installs, and commissions your controls.
Controls & equipment audit
