Rooftop Unit Diagnostics and System Troubleshooting
We deliver commercial HVAC rooftop repair in Westborough, MA. Our technicians use commercial-grade tools to identify electrical faults, refrigerant issues, and control system failures. We also document our findings so that you can understand the cause and scope of the rooftop HVAC repair in Worcester County before we start work.
Electrical, Thermostat, and Control System Repairs on RTUs
Electrical problems cause some of the most disruptive rooftop unit failures in commercial buildings. Our electricians inspect and repair contactors, capacitors, control boards, wiring, and thermostat connections. We can also address building automation system integrations.
Refrigerant Leak Detection and Repair
Low or leaking refrigerant reduces cooling capacity, putting strain on compressor components. Our technicians use leak detection equipment to look for refrigerant issues before recharging the system. We repair the source of the leak and confirm proper charge before we finish.
Airflow, Blower, and Ductwork Repairs on Rooftop Units
Restricted or uneven airflow often traces back to a rooftop unit problem. We inspect blower assemblies, belts, motors, and ductwork connections to find the source. We then restore proper airflow balance so that every zone in your building hits the temperature it needs.
Preventive Maintenance for Commercial Rooftop Units
Scheduled maintenance reduces the frequency and severity of RTU repairs over time. We build maintenance plans around your facility’s operating schedule and equipment needs.
