Replace Heat Pump Compressor in Chicago

We recently replaced a failed compressor in a water source heat pump at a high-rise condo in Chicago. Compressor replacement in a high-rise environment requires precise diagnostics, careful isolation, and controlled refrigerant handling. Our technician confirmed compressor failure using electrical testing, amperage readings, and winding inspections. After diagnosis, we shut off power and isolated the unit from the building’s water loop system to ensure a safe repair.

We protected surrounding finishes before removing the failed compressor. The refrigerant lines were carefully cut and disconnected while preventing moisture and debris contamination. We installed a new factory-approved compressor and brazed the refrigerant connections to manufacturer specifications.

Next, we pressure-tested the refrigerant circuit with nitrogen to verify leak-free connections. After passing the pressure test, we pulled a deep vacuum to remove moisture and non-condensable gases. We then charged the system with the exact manufacturer-specified refrigerant amount and restored water flow through the heat exchanger.

Once operational, we monitored suction and discharge pressures, checked water loop temperatures, verified condensate drainage, and confirmed proper thermostat operation. The water source heat pump was returned to reliable heating and cooling performance.
