Field-Diagnosed Failures – Tempe Commercial Stock

RTU High Head – ASU Campus Load

Tap for diagnosis

High occupancy + construction dust. We measure approach temp, foam-clean microchannel coils, restore head pressure to sub-325 psi, and document delta.

Economizer Failed – Mill Ave Retail

Tap to flip

Sensor drift or stripped actuator gear. We calibrate per ASHRAE 90.1, restore free cooling, cut compressor runtime by 35-45%.

VFD Comm Loss / Harmonics

Tap to flip

BACnet comm drop or THD >8%. We re-terminate, install line reactor, restore bypass contactor – same-shift.

Tempe's Commercial HVAC Failure Patterns

Tempe's unique mix of high-density ASU campus buildings, Mill Avenue foot traffic, and South Tempe industrial warehouses creates three distinct failure vectors. 74% of our Tempe emergency calls involve condenser coil fouling from construction dust near the 202/101 corridors. Campus buildings see VAV control failures from DDC pressure sensor drift. We address all with precision diagnostics.

High occupancy load: ASU classroom buildings run 20-30% higher cooling demand. We check compressor staging and recommend VFD speed resets.
Mill Avenue retail: Glass-front storefronts create solar gain. We measure envelope load and recommend reflective films or economizer schedule changes.
South Tempe industrial: Warehouse RTUs often have undersized condenser coils. We recommend upgraded coils or additional condenser fan staging.

Local field data: Tempe facilities on our bi-annual PM schedule see 77% fewer after-hours calls and 26% lower cooling energy spend.

Most Frequent 24/7 Calls – Tempe Commercial

Condenser Coil Fouling

Construction dust + urban pollution. We chemical foam-clean, approach temp from 30°F to 12°F, restore heat rejection.

VFD Overvoltage Fault

Utility spikes near ASU campus. We install line reactor, adjust decel ramps, verify bypass contactor.

Supply Fan Belt Failure

Sheave misalignment. We laser-align, install cogged belts, verify static pressure setpoint.

Burning Smell from RTU

Blower motor winding failure. We megger-test, replace motor, check all electrical connections.

Short-cycling

Dirty evap coil or bad suction pressure transducer. We clean and recalibrate.
