DCM9 complete; AC; (8) 20x20x2, (4) 20x25x2, (3) 16x25x2, (1) 20x25x1, (1) 16x25x1, (1) 16x20x1, (1) 10x45x1 replaced (2) Washable filters cleaned. All systems are cooling, most units were still on Heat mode, tested systems and returned them to Heat mode.. Outdoor temperatures were a little low for proper testing procedures but refrigerant pressures and temperatures were appropriate for indoor and outdoor conditions. Kitchen unit is cooling, system was extremely low on refrigerant, added 4 lbs of R22 refrigerant. Compressor runs, then binds, shuts down and restarts and repeats the sequence. System cooled the kitchen from 95* to 78* during location maintenance.

Systems are fully functional with the following exceptions. RTU #1 ( Server/office ), : Straight AC; indoor fan blower motor has seized and will no longer spin. Blower motor photo attached RTU #3 ( offices ) : Gas valve fails to open. Input pressure on gas valve 24 in WC. Gas valve max pressure is 1/2 psi or 14 in WC. Gas regulator has failed. 3/4 in pipe diameter Photo attached System #6 ( Kitchen ) : System is approximately 4 lbs low on R22, pressures are low on both high and low sides. Superheat is extremely elevated. Indoor metering device is a piston while the outdoor fan has a low ambient kit that is keeping the system from freezing. System is 27 years old Request replacement quote for System #6 and RTU #1. Request repair quote for RTU #3 and RTU #1
