Setpoint Services completed a commercial rooftop HVAC repair at Renzo Gracie Pflugerville after diagnosing a severe refrigerant restriction caused by a plugged liquid line filter drier. Prior to repair, the RUUD rooftop air conditioning system was operating with discharge pressures exceeding 500 PSIG and suction pressure near 20 PSIG, indicating a major restriction that placed excessive stress on the compressor. The refrigerant was recovered, a leaking Schrader valve and restricted liquid line filter drier were replaced, and the refrigeration circuit was pressure tested to locate and repair a refrigerant leak. The system then underwent a triple evacuation and deep vacuum to remove moisture and non-condensables before being recharged with the manufacturer-specified 8-pound refrigerant charge. Final operating pressures stabilized at approximately 60 PSIG suction and 260 PSIG discharge, confirming the rooftop HVAC system had returned to normal cooling operation. Due to the prolonged operation under extreme head pressure, recommendations were provided for future compressor replacement or complete rooftop HVAC system replacement to improve long-term reliability and efficiency. This commercial HVAC repair included refrigerant leak repair, filter drier replacement, refrigerant recovery and recharge, pressure testing, evacuation, and rooftop air conditioning performance testing in Pflugerville, Texas.
