Expert Commercial HVAC Repair in Nashville
A commercial HVAC failure can interrupt work, affect tenant comfort, or leave part of a building unusable. Harpeth Air provides commercial HVAC repair in Nashville and Middle Tennessee for rooftop units, split systems, VRF systems, chillers, and building controls.
No cooling, weak airflow, repeated shutdowns, and temperature complaints can have different causes. A useful repair assessment considers the equipment, controls, airflow, and service history before selecting a component to replace.
Call with the property address, symptoms, and equipment information you have. Tell us how the problem affects your business and discuss the next available service visit. Timing depends on the work, site access, technician availability, and any parts needed.
For no heat, ignition trouble, or a heater that keeps shutting down, see our commercial heating repair services. Gas rooftop equipment, unit heaters, and commercial heat pumps have different diagnostic needs.
Commercial HVAC Repair Services We Provide
Equipment Outages
For a unit that has stopped heating or cooling, describe the affected space and any alerts when you call. Call to discuss service availability and access requirements.
Diagnostic Services
Diagnostic work helps distinguish equipment faults from airflow or control issues. Discuss the symptoms, previous repairs, and any recent changes to the building or system.
Scheduled Repair
A known fault or worn component may be suitable for planned repair. Ask about parts availability, the expected scope, and any shutdown needed so you can coordinate the work with building occupants.
System Performance Restoration
A running system can still leave rooms too warm, too cold, or short of airflow. Harpeth Air provides commercial system service, including work on controls, refrigerant systems, and air distribution.
Equipment We Repair
Common Commercial HVAC Problems in Nashville
Cooling demand, outdoor debris, changing occupancy, and equipment wear can all affect a commercial system. These symptoms are useful to mention when arranging service; an on-site assessment determines the cause.
Compressor Failure
Often caused by refrigerant leaks, electrical issues, or lack of maintenance. We diagnose the root cause, not just the symptom, to prevent repeat failures after compressor replacement.
Refrigerant Leaks
Commercial systems with extensive refrigerant piping are susceptible to leaks at joints, fittings, and coils. We use electronic leak detection and nitrogen pressure testing to locate and repair leaks accurately.
Economizer Failures
Damper, sensor, or control faults can affect outdoor airflow and comfort. Economizer repair may involve the actuator, sensors, controls, or related components, depending on the diagnosis.
Condenser Coil Fouling
Nashville cottonwood, pollen, and debris clog condenser coils, causing high head pressure and compressor strain. Regular coil cleaning is part of our maintenance programs, but we also provide coil cleaning as a standalone service.
Control and Thermostat Issues
Commercial buildings often have complex control systems that can malfunction due to sensor failures, wiring problems, or programming errors. We troubleshoot and repair all types of commercial controls from simple thermostats to full BAS platforms.
