Repair and maintenance for commercial rooftop package units (RTUs), split systems, and light commercial facilities.

Common Symptoms

• Temperature fluctuations impacting dining rooms, retail floors, or office suites
• Server room or equipment closet temperatures climbing above safe thresholds
• Rooftop unit (RTU) making loud belt-squeal or bearing grinding noises
• Elevated utility charges and peak demand charges on commercial electric meters
• Fresh air economizer dampers stuck open or closed, violating ventilation codes

Possible Causes

• Worn blower drive belts or misaligned pulleys in rooftop package units
• Economizer actuator motor failure or faulty enthalpy sensor calibration
• Three-phase electrical phase imbalance or failed magnetic motor starter contactor
• Multiple-stage compressor lockout on low-pressure or freeze-stat safety
• Severely neglected commercial air filtration racks loading down blower static

Safe Homeowner Checks

• Verify building management thermostat schedules are set to occupied cooling modes
• Check for tripped circuit breakers in commercial distribution panels
• Confirm that roof drainage does not allow standing water to pool around RTU bases

Frequently Asked Questions

What is the most common cause of commercial rooftop unit failure?

Failed blower belts, dirty condenser coils exposed to harsh roof radiation, and failed economizer actuators are among the most frequent service issues in commercial rooftop units.

How quickly should a server room cooling failure be addressed?

Immediately. Modern server hardware generates intense heat loads that can cause irreversible hardware damage and data center outages within 30 to 60 minutes of cooling loss.
