service a commercial refrigeration unit that was not holding the correct temperature. The customer reported that perishable goods were spoiling faster than normal. After inspecting the system, I discovered a faulty temperature control thermostat that was causing the unit to shut off prematurely. I verified the issue by testing continuity and observing the system’s cycle behavior. I replaced the thermostat, monitored the temperature drop, and confirmed the unit reached and maintained the correct setpoint. The system is now operating efficiently, and the issue has been resolved.
commercial air conditioning issue where the tenant reported warm air blowing from several vents. After inspecting the rooftop unit, I found that the condenser coil was heavily clogged with dirt and debris, restricting heat transfer and reducing cooling efficiency. I confirmed the problem by checking refrigerant pressures and airflow, both of which were outside normal operating ranges. I thoroughly cleaned the condenser coil, checked the filters, and verified that the blower motor and compressor were functioning properly. After a full system test, the unit is now cooling effectively, and interior temperatures have stabilized.
The building manager reported inconsistent heat and cold spots throughout the office. Upon inspection, I found that one of the rooftop units had a faulty thermostat that wasn’t communicating properly with the control board. I verified the issue by checking voltage readings and confirming the unit wasn’t cycling correctly. I replaced the thermostat, reprogrammed the settings, and tested the system to ensure even heat distribution. After verifying airflow and temperature balance throughout the zones, the system is now running efficiently and maintaining proper comfort levels.
