Rooftop Unit (RTU) Service in Nashville
Rooftop unit repair, gas heating service, replacement, and maintenance in Nashville. Call Harpeth Air about RTU faults and service for your commercial building.
Nashville's Rooftop Unit Specialists
A packaged rooftop unit can serve one tenant space or a larger area of a commercial building. When cooling, heating, or airflow changes, the affected unit, controls, and spaces need to be considered together. Harpeth Air provides RTU repair, replacement, and maintenance in Nashville and Middle Tennessee.
RTU problems can involve compressors, fan motors, belts, ignition components, refrigerant circuits, economizers, or controls. Describe the symptoms and any fault codes you already have when calling about service.
For an aging unit or repeated breakdowns, discuss both the repair and the replacement scope. Equipment selection is only part of a rooftop changeout: roof access, curb fit, lifting arrangements, electrical connections, and controls also affect the work.
Rooftop Gas Heat and Fall Startup
Cooling performance does not confirm that a rooftop unit's heating section is ready for colder weather. Gas-heating service can involve the burners, heat exchanger, ignition and flame safety, pressure switches, controls, combustion, and airflow. The unit's condition and maintenance scope determine the work needed.
For a unit that will not heat or repeatedly locks out, explore commercial heating diagnosis and repair. To plan seasonal checks, discuss commercial preventive maintenance and the roof access your property requires.
RTU Services We Provide
RTU Repair
We provide rooftop unit diagnosis and repair for cooling, heating, airflow, and control faults. Repair timing depends on the diagnosis, access, technician availability, and the parts required.
RTU Replacement
Harpeth Air provides RTU replacement and changeouts, including curb and crane coordination. Discuss equipment selection, electrical and control connections, site access, and startup requirements before approving the project.
RTU Maintenance
RTU maintenance can include filters, coils, belts, electrical components, refrigerant systems, controls, drains, and heating components. Confirm the applicable tasks, materials, and visit schedule in the maintenance scope.
Economizer Service
Economizers use outdoor air for cooling when conditions allow. Damper, actuator, sensor, and control issues can affect their operation. Harpeth Air offers economizer repair and service as part of its rooftop unit work.
Access and Scheduling for Rooftop Work
Roof access arrangements matter before a visit. Share the access method, unit location, on-site contact, and any property requirements so they can be considered when planning service.
For replacement work, discuss crane setup space, curb compatibility, tenant notification, and the equipment shutdown window. Confirm responsibility for site approvals and any work by other trades in the proposal.
Common RTU Problems in Nashville
Outdoor exposure, debris, equipment wear, and changing building demand can contribute to RTU problems. These are examples of issues to discuss, with the final repair or maintenance scope determined by the equipment condition.
Compressor failures from dirty condenser coils and resulting high head pressure
Inspect coil condition and diagnose the cause of high operating pressure before selecting the repair.
Economizer dampers stuck open or closed, wasting energy and causing comfort issues
Annual economizer calibration and component replacement as needed.
Condensate drain blockages causing water leaks into the building
Discuss drain inspection and cleaning in the maintenance scope for the affected unit.
Gas valve and ignition failures in heating season
Fall maintenance with combustion analysis and ignition system testing.
Belt wear and failure causing loss of airflow
Confirm belt inspection and any replacement materials in the maintenance or repair scope.
Why choose Harpeth Air for rooftop unit service
Harpeth Air offers repair, maintenance, and replacement for commercial rooftop equipment. That gives building owners options for addressing a current fault and planning the next stage of equipment care.
Call with your property address, unit details, and symptoms to discuss service availability. If replacement is being considered, share known access restrictions and the operating hours your project needs to account for.
Plan rooftop service before the site visit
A rooftop repair and a full changeout have different access, equipment, and scheduling needs. Start with the information you already have; there is no need to climb onto the roof to prepare a request.
Identify the unit and affected area
Share the roof plan or unit number, make and model if available, symptoms, and the space served. Explain whether the problem occurs in heating or cooling mode and whether one unit or several units are affected.
Explain the site requirements
Discuss roof access, an on-site contact, building operating hours, and any shutdown restrictions. For replacement, raise crane access, curb compatibility, and landlord approvals.
Compare repair and replacement
Review equipment condition, repair history, parts lead times, and replacement scope. Ask what the proposal includes for controls, electrical work, lifting, startup, and disposal.

Frequently Asked Questions
How long do commercial rooftop units last?
RTU service life varies with equipment design, use, exposure, condition, and maintenance history. Age alone does not decide whether to replace a unit. Review recurring faults, component condition, parts availability, and operating needs before choosing a repair or replacement.
When should I replace my RTU instead of repairing it?
Compare the repair scope and cost with the condition of the whole unit, past failures, parts availability, and a replacement proposal. For a changeout, include curb compatibility, electrical and control work, lifting access, and the shutdown window in the comparison.
Can you replace my RTU with a higher-efficiency model?
A replacement can include higher-efficiency equipment, but the value depends on building demand, operating hours, utility costs, and installed cost. Ask for a comparison that includes the assumptions behind any projected savings instead of relying on a general payback estimate.
Do you service RTUs from all manufacturers?
Harpeth Air services commercial rooftop units from major manufacturers, including Carrier, Trane, Lennox, York, and Daikin. Share the make, model, unit size if known, and the issue so we can discuss the equipment at your property.
