ACT Commercial HVAC Emergency Repair FAQ
What qualifies as a commercial HVAC emergency?
A commercial HVAC emergency is a failure that threatens business operations, production, inventory, equipment, building safety, regulated environmental conditions, or occupant use of the facility. Examples include chiller shutdowns, boiler failures, loss of process cooling, control-system failures, frozen piping risks, ventilation failures, and widespread loss of heating or cooling.
Does ACT provide 24-hour emergency HVAC service?
ACT provides 24/7 priority emergency response for Priority Maintenance Program clients and approved priority accounts. Other commercial facilities should call 845-565-COOL to confirm current emergency availability.
Can ACT repair large commercial and industrial HVAC systems?
Yes. ACT services large-capacity rooftop units, commercial and industrial chillers, cooling towers, boilers, pumps, air handlers, VRF systems, ventilation equipment, and connected building controls.
Does ACT service production-critical HVAC systems?
Yes. ACT works with facilities where HVAC supports production, sterilization, laboratory conditions, pharmaceutical operations, food processing, temperature-sensitive materials, and other critical processes.
Can ACT diagnose HVAC controls during an emergency?
Yes. ACT troubleshoots Building Automation Systems, Direct Digital Controls, sensors, actuators, controllers, VFDs, communication networks, and equipment sequences. Automated Logic Corporation is a primary controls systems vendor for ACT.
Will ACT recommend replacing the equipment immediately?
Not automatically. ACT takes a repair-first approach. We recommend replacement when repair is unreliable, unsafe, unavailable, or no longer makes operational sense.
What information should I have when calling?
Provide the facility address, equipment type, affected area or process, alarm messages, current indoor or process conditions, when the failure began, and any recent repair or control work. Do not delay the call to collect information you do not already have.
