Adrian
September 2026
A commercial customer in Galveston reported an issue with a sensor on their unit.
Adrian found an EC52 code, which is a coil sensor code, and a PC03 code also flashed on the head. He tested each sensor and all were pretty close to spec, but the display on the control board was not working. Adrian changed out the control board.
After the control board was replaced, the unit was running.
Brandon
September 2026
Brandon found the drain lines backed up at a Galveston commercial property, with one draining into the store. He cleared the drains and replaced the PVC with green anti microbial PVC to help mitigate backups. He then installed inline float switches on both units to shut the system down in a future backup and replaced all filters (16x20, qty 8).
Matthew
September 2026
A Galveston restaurant reported that the AC keeps freezing up.
Matthew found that the kitchen unit, the dining area unit, and the dehumidifier all had clogged drain lines, and in the dining area the float switch was cutting off the unit because the drain pan was filled up. He cleaned out the drain lines on all three units and checked pressures on both air-conditioning units.
Pressures on both air-conditioning units were good and the units were cooling well.

The customer reported an issue with humidity and moisture in the duct system.
Brandon found that the upstairs system was oversized and set on too high of air flow, causing high humidity in the space of 70%+. He also found that the downstairs system was oversized, undercharged, and set too high on air flow, causing high humidity. Brandon completed a diagnostic on both systems to identify these causes.
Galveston Island's direct ocean exposure means HVAC outdoor units face constant salt spray that corrodes condenser coils, electrical connections, and cabinet panels far faster than inland locations. Coastal-rated equipment and frequent cleaning are essential.
Galveston's humidity regularly exceeds 80%, forcing AC systems to handle heavy moisture removal alongside cooling. Without proper dehumidification, homes experience clammy air, mold growth, and premature equipment wear.
Galveston's island location makes HVAC systems vulnerable to hurricane-force winds, storm surge, and power surges. Proper equipment anchoring, surge protection, and post-storm inspections are critical for system longevity.
Galveston's mild winters and long, hot summers mean AC systems run 8-9 months per year — significantly more than inland areas. This extended runtime accelerates wear on compressors, fans, and electrical components, making proactive maintenance essential.
