Commercial Heating Repair & Service in Nashville
Commercial heating repair in Nashville for gas rooftop units, unit heaters, and heat pumps. Call Harpeth Air about no heat, ignition faults, or fall maintenance.
Heating Service for Nashville Commercial Buildings
A heater that will not start, runs without warming the space, or repeatedly shuts down can disrupt a business as cooler weather arrives. Harpeth Air provides commercial heating diagnosis, repair, and maintenance for businesses in Nashville and Middle Tennessee.
Our commercial heating work includes heater diagnosis, pressure-switch replacement when indicated, and maintenance involving burners, heat exchangers, flame safety, controls, combustion, and airflow. The equipment assessment determines which work is appropriate; a fault code alone does not establish the cause.
Call with the property address, affected space, and equipment information you already have. We can discuss service availability, access, and the proposed assessment. Parts, repair scope, and any follow-up work depend on the findings.
Commercial Heating Equipment and Service Needs
Gas Rooftop Units
A packaged unit may cool the building normally but develop a fault when heating is first needed. Heating service considers the gas-heating section, ignition sequence, safeties, controls, and airflow. Share the roof access arrangements when booking rooftop unit service.
Commercial Unit Heaters
Unit heaters in shops, warehouses, and other commercial spaces can have ignition, flame-safety, control, or airflow problems. Note the heater location, mounting access, fuel type if known, and which work areas are affected so the visit can be planned around your building.
Commercial Heat Pumps
Heating complaints can involve equipment operation, thermostat or building controls, airflow, or supplemental heat. Describe whether the issue affects one zone or the whole building, and share any alerts and recent changes to the operating schedule.
No Heat, Ignition Faults, and Repeated Shutdowns
Useful details include whether the blower runs, whether the unit starts and then stops, which thermostat or building-control zone is calling for heat, and when the problem began. Share fault messages already visible to your facilities team; you do not need to open the equipment or climb onto the roof before calling.
Diagnosis follows the equipment's heating sequence and considers the controls and conditions involved. A pressure-switch or flame-safety fault requires investigation before replacing a component. For a building with conflicting schedules, setpoints, or zone complaints, commercial HVAC controls service may be part of the assessment.
Discuss the diagnosis, proposed repair, parts requirements, and any shutdown before approving work. Where recurring problems or equipment condition raise replacement questions, compare the repair with a defined replacement scope.
Plan Fall Heating Maintenance Before Daily Use
Fall is a useful time to review heating operation, equipment condition, and occupied-hour schedules. Start with an equipment list and note unresolved heating complaints from the previous season. Discuss burners, heat exchangers, ignition and flame safety, controls, combustion, and airflow for gas equipment; the agreed tasks should match the units at your site.
A commercial maintenance plan can address seasonal service alongside repairs identified during a visit. Confirm covered equipment, visit frequency, findings, and repair approvals in your service agreement.
Prepare a commercial heating service request
Bring the information you already have. There is no need to open a heater, reset a safety control, or access the roof to gather details before calling.
Identify the affected spaces
Note which tenant, room, or work area is without heat, when the issue started, and whether it is constant or intermittent. Include any alerts already visible on the thermostat or building controls.
Share the equipment and access
Provide the unit identifier, heater type, make, and model if available. Explain roof or elevated-equipment access, site restrictions, and who can meet the technician and authorize work.
Plan the next step
Discuss current availability and the diagnostic visit. If requesting fall maintenance, identify covered units and agree on the inspection, cleaning, operating checks, and reporting appropriate to that equipment.

Frequently Asked Questions
What commercial heating equipment can I call about?
Contact Harpeth Air about gas-heated rooftop units, commercial unit heaters, and commercial heat pumps. Share the manufacturer, model if available, location, and symptoms so we can discuss the equipment and service needed at your building.
Can you help when a commercial heater will not start?
Yes. Harpeth Air provides commercial heater diagnosis and repair, including ignition, pressure-switch, flame-safety, and control issues. Similar symptoms can have different causes, so the equipment needs an assessment before choosing a repair. Call to discuss the next available visit and any access requirements.
What should a fall commercial heating visit cover?
The scope depends on the equipment and its condition. For gas heating, discuss burners, heat exchangers, ignition and flame safety, controls, combustion, venting, and airflow. For heat pumps, discuss heating-mode operation, controls, and any supplemental heat. Confirm applicable tasks, materials, and reporting in the maintenance scope.
Does a pressure-switch fault always mean the switch needs replacing?
No. A pressure-switch fault needs diagnosis in the context of the heater and its operating sequence. The assessment may identify a switch problem or another condition affecting operation. Safety controls should not be bypassed to keep a heater running.
What if I smell gas at the building?
Leave the affected area immediately. From a safe location, call 911 and your gas utility emergency line. Do not stay inside to troubleshoot or wait for a routine HVAC appointment.
