Signs Your Commercial HVAC Needs Service
Commercial HVAC systems often show early warning signs before major failure occurs. Schedule professional service if you notice:
Uneven temperatures across zones. Hot and cold spots that don’t match thermostat settings often point to failing zone dampers, BAS calibration drift, or ductwork issues.
Unusual noise from rooftop units. Grinding, banging, or screeching sounds from commercial RTUs typically indicate bearing failure, loose components, or compressor issues needing immediate attention.
Energy bills climbing with no usage change. A 15-20% spike in HVAC-related energy costs usually means equipment is working harder to maintain the same output. Refrigerant leaks, fouled coils, or controls drift.
Frequent short cycling. Units turning on and off rapidly indicate oversized equipment, low refrigerant charge, failing contactors, or thermostat/sensor problems.
Refrigerant odor or moisture around equipment. Any visible leak, ice buildup, or chemical smell around chillers, condensers, or refrigeration units requires immediate professional diagnosis.
BAS alerts or override codes. Building automation systems throwing repeated alarms or requiring manual overrides signal controls failures that compound into larger system problems.
