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.

How We Handle Commercial HVAC Projects

GENMECH HVAC follows a military-disciplined process on every commercial job: systematic diagnosis, transparent communication, and precision execution. No guesswork, no shortcuts.

  1. 1

    Initial Assessment & Diagnostics

    We arrive with OEM level diagnostic tools for Trane, Rheem, Bryant, and Lennox. Full system inspection covers refrigerant pressures, electrical, mechanical components, and controls. We find the root cause, not just the symptom.

  2. 2

    Transparent Diagnosis & Options

    You get a clear explanation of what’s wrong, why it happened, and your options: repair vs. replace, short term fix vs. long term solution. No industry jargon. No pressure. Real numbers.

  3. 3

    Precision Repair or Installation

    Factory spec parts. Manufacturer procedures. Whether it’s a compressor rebuild on a chiller or a 20 ton RTU swap, every repair meets or exceeds OEM specifications. No shortcuts.

  4. 4

    System Verification & Documentation

    After every job, we run a full system test, performance verification, and documented results. You know exactly what was done, what was measured, and what to watch for. We also recommend a PM plan to prevent the same issue from recurring.
