Nothing to complain about
Our HVAC installers replaced a 10 ton Carrier unit at a coffee shop in Berkeley, California. After a 7am crane lift to remove the old unit and place the new unit, our technicians proceeded to reconnect all electrical, drain lines, and installed the economizer. System pressure tested. Sensor and thermostat replaced. Unit started up and operational. Install complete.
Approved refrigeration repairs scheduled today for two commercial coolers. Unit #1 needed a new high pressure transducer, which our technician replaced. System #2 needed a leak check and repair. After pumping down the system and pressurizing with nitrogen, our technician located two refrigerant leaks: one on the second stage filter core housing and another on the suction line. Repaired both leaks and tested system. Units are operating normally again and have dropped down to correct operating temperatures.
RESSAC HVAC-R technician was dispatched to school in the bay area reporting water leaks. Facility manager had previously called a roofing contractor and they found leaks to be coming from a 15 ton York package unit. Unit is very old and after inspection technician found seals around doors and ducts are wearing out. Technician resealed and taped all weak points around unit. Due to age and condition this unit would be a good candidate for replacement. Recommend installation of new unit when budget allows.
