VRF Systems

VRF systems are becoming an increasingly popular choice for heating and cooling in commercial buildings. But just like more traditional HVAC equipment, it’s important to get proper preventative maintenance on VRF/VAV systems to prevent costly repairs and lengthy downtime. Our HVAC Service team can maintain your systems so they keep running efficiently and respond with quick repairs if your systems do experience a breakdown.

Data Center Facilities

Data centers are mission critical facilities and the importance of functioning HVAC systems in them cannot be understated. Without efficient cooling and ventilation, data centers can stop working, leading to significant consequences beyond the facility. LONG can deliver the preventative maintenance necessary to keep HVAC equipment working in data centers, the repairs needed in the event of an emergency, and building automation solutions and analytics that give you better understanding and control on how the various systems in the facility operate.
