Commercial HVAC Repair in Tupelo, MS

What we repair on commercial systems

• Compressors, contactors, and electrical controls on rooftop units
• Blower motors, belts, bearings, and drive assemblies
• Economizers, dampers, and actuators that stick or fail closed
• Refrigerant circuit faults, including leak identification
• Gas heat sections and safety controls on package units
• Thermostats, zone controls, and building control interfaces
• Condensate and drainage problems on rooftop and closet equipment

Why commercial diagnosis takes a different approach

Commercial units often have multiple stages, multiple circuits, and economizer or ventilation logic that a residential system does not have. A unit that appears to be low on capacity may in fact be pulling in outdoor air through a damper that failed open.

We check the whole sequence, including ventilation and controls, before condemning mechanical components. That avoids replacing a compressor to solve a damper problem.
