Commercial HVAC Repair

Commercial Rooftop Unit Repair

When a rooftop unit goes down, comfort complaints can turn into lost productivity fast. Comfort Solutions Heating and Cooling provides responsive commercial RTU diagnostics and repair to restoring cooling, heating, airflow, and control issues with a clear plan and professional workmanship.

Fast RTU Troubleshooting and Accurate Diagnostics

Commercial rooftop units are complex systems. Electrical, refrigerant, gas heat, controls, and airflow all work together. We isolate the failure quickly, explain what is happening in plain language, and recommend the most cost-effective path to get your building stable.

Common Rooftop Unit Problems We Fix

• RTU not cooling or not heating
• Short cycling, lockouts, and nuisance trips
• Low airflow, hot or cold zones, and comfort imbalance
• Sensor, thermostat, or building control communication issues
• Refrigerant leaks, frozen coils, and poor capacity
• Ignition, burners, gas valve, and heat exchanger concerns
• Fan motor, belts, bearings, and economizer issues
• Storm or hail-related damage assessments and repairs

All Brands, Small to Large Commercial Systems

We service and repair all major RTU brands and a wide range of commercial setups, including:

• Split systems (commercial furnaces and AC)
• Ductless systems for offices and tenant spaces
• Makeup air units, unit heaters, infrared heaters

Repair vs. Replace

Sometimes the best decision is repair. Other times, repeated breakdowns and high operating costs make replacement the smarter long-term move. If replacement becomes the better option, we will walk you through sizing, efficiency, and lifecycle cost, not just the lowest upfront price.

Commercial Maintenance and Service Plans

Preventative maintenance is one of the best ways to avoid emergency calls during peak season. We offer commercial maintenance options designed for property owners, facility managers, and tenants, focused on reliability, performance, and predictable budgeting.

Financing Support for Commercial HVAC Upgrades

If your RTU or commercial system needs replacement, Comfort Solutions Heating and Cooling can help you explore financing options so you can upgrade equipment without stalling other building priorities.
