PROBLEM

Storer Services was called to evaluate air-conditioning units serving rest area bathrooms that were not cooling properly. The system consisted of Addison 12.5-ton split systems with heat pumps and RenewAire energy recovery ventilators.

The spaces were experiencing inadequate cooling and elevated humidity levels, creating an uncomfortable environment and indicating underlying system performance issues.

SOLUTION

A detailed inspection uncovered multiple contributing problems. The control system software and hardware were not properly interfacing with the Addison units, limiting system performance. The energy recovery ventilator fan was also inoperable due to a clogged outside air inlet screen filled with dust and debris.

Our technicians performed a full system restoration, including cleaning the inlet screen, repairing refrigerant leaks, replacing defective components such as the condenser fan motor, and properly charging and tuning the refrigerant system.

To ensure year-round performance, a follow-up service was scheduled during colder weather to fine-tune heating set points and make any additional adjustments needed for optimal operation.

LEGACY

Following service, the HVAC systems were restored to full functionality, providing reliable cooling, heating, and significantly improved humidity control.

The facility now benefits from a more comfortable and properly conditioned environment, with performance exceeding previous expectations. The successful repair highlights the value of thorough diagnostics and proactive follow-up to ensure long-term system reliability.
