Tech returned to leak search Gas Pack #1. Six 20*20*1 filters were replaced yesterday. Chicken breaded filters are gone. Pressurized system up to 200 psi of nitrogen and trace gas on each circuit. Tech found no refrigerant leaks at indoor coil. Indoor TXV for circuit 1 has some oily residue, but tech confirmed no refrigerant leaks with ultrasonic or soap bubble. Tech found valve core for true suction port leaking. Tightened core, but it still leaked. Replaced core to stop leak. Tech found large refrigerant leak in oily spot at top right corner of micro channel condenser coil. See picture. Confirmed with ultrasonic detector. Need to call customer to quote condenser coil replacement. Due to coil size, at least two techs and a lift are required. 21.3 lbs of R410a and two larger size liquid line filter driers (DHY01470) are also needed. Left nitrogen in circuits. Staff has a bucket beneath fallen ceiling tile in tall ceiling in dining room. Looks like return duct had water dripping. Tec
Maurice Brown 919-648-7757. On arrival, manager on duty reported dining room is running correctly, but kitchen is not. In front of Gas pack 1 on the roof are two old compressors and an old blower motor. Looks like both compressors and belt drive blower have been replaced. We documented shorted compressors in February 2023. Indoor coil is frozen with several inches of thick ice. Compressor 1 (larger circuit is completely frozen up and compressor 2 (smaller) was not running. Four 20*20*1 pleated filters in the ceiling are completely clogged with breading dust. Two inch filters in unit are fairly clean and a few weeks old, but frozen to coil. Both circuits are nearly void of R410a. Under 60 psi of R410a standing pressure tested at both liquid lines and true suction ports. Will need to return at a later date to leak search system after coil thaws out. Tech let Mr Brown know of findings and that system is down. Tech left Y1 and Y2 disconnected and disconnect off. Tech left estimate on
TECH DIAGNOSED SPLIT SYSTEM #5 WHICH IS A NEW SYSTEM, THE POWER HAD WENT OUT. AFTER DIAGNOSTICS TECH FOUND THERMOSTAT WIRE NOT CONNECTED PROPERLY, AND THERE WAS A FUSE BLOWN INSIDE OF AIR HANDLER. TECH TOOK WIRES OIT OF THERMOSTAT AND PUT THEM BACK IN PROPERLY, ALSO TECH CHANGED FUSE IN AIR HANDLER. SPLIT SYSTEM #5 IS BACK RUNNING PROPERLY.
PERFORMED CMA INSPECTION ON 3 GAS PACKAGE SYSTEMS, 6 EXHAUST FANS AND 2 MAKE UP AIR SYSTEMS. ALL SYSTEMS HAVE A PROPER DELTA T AND ARE PERFORMING PROPERLY AT THIS TIME. COMPLETED FILTER CHANGE OF 8-20x20x1 FILTERS,8-16x25x2 FILTERS, 20-20x20x2 FILTERS AND 4-20x25x2 FILTERS. PICTURES AND PERFORMANCE REPORT ARE ATTACHED TO THIS INVOICE.
Found the recently replaced thermostat programmed incorrectly. Thermostat was set for heat pump instead of gas and hot-gas dehumidification mode disabled. Tech corrected the settings and assured both circuits operated prior to departure as well as the hot-gas dehumidification. Temperature dropped throughout visit. No charge per office due to recent CMA visit.
TECH PERFORMED CMA INSPECTION ON 3 GAS PACKAGE SYSTEMS, 6 EXHAUST FANS, AND 2 MAKE UP AIR SYSTEMS. UPON ARRIVAL MANAGER OF STORE STATED THAT THERMOSTAT FOR KITCHEN AREA WAS NOT WORKING PROPERLY, TECH DIAGNOSED THERMOSTAT AND FOUND BUTTONS TO CHANGE SETTINGS AND TEMPERATURE WAS NOT WORKING ON THERMOSTAT. TECH REPLACED THERMOSTAT WITH APPROVAL FROM MRS. HUBBARD, TECH COMPLETED FILTER CHANGE OF 8-20x20x1 FILTERS, 24-20x20x2 FILTERS AND 12-16x20x2 FILTERS. ALL SYSTEMS ARE PERFORMING PROPERLY AT THIS TIME. PERFORMANCE REPORT AND PICTURES ARE ATTACHED TO THIS INVOICE.

Tech preformed CMA FULL SERVICE on 9 Split Systems, 1 Air Make-up Unit, and 2 Exhaust Fans. *Split System #9 is still down from previous diagnosis of failed compressor, compressor shorted to ground. This was diagnosed on 10/5/23. Tech recommends replacing System. *Split System #3 is still down from previous diagnosis on 8/17/23 of failed blower motor, motor is locked up. Compressor also failed megohm test. Due to age and these challenges, tech recommends replacing system over repair. *Exhaust Fan #1 ( dishwasher) is still down with locked up motor, diagnosed on 4/14/23. Tech recommends replacing Exhaust Fan. *Split System #7 is operating at this time but has multiple challenges. Compressor tested in caution area of megohm test. Run capacitor is at lowest tolerance in operating range. Compressor plug has gotten extremely hot at some point and become disfigured. Blower motor is operating at higher amps than FLA listed, indicating motor is beginning to fail electrically. And evaporator c

Tech performed CMA full service on 3 gas package units, 1 make up air unit with condensing towers, 1 make up air without, and 6 exhaust fans. Upon inspection tech found the gas pressure feeding each package unit low. Tech adjusted the gas pressure and confirmed system is operational. All systems are running properly at this time. Tech has attached system performance reports and pictures to this invoice.
Tech performed CMA full service on 3 Gas Package Units, 2 Air Make Up Units, and 6 Exhaust fans. Upon inspection tech found the gas pressure to all package units low. Tech was able to adjust units 1 and 3 to proper pressure but due to corrosion fusing the gas valve adjustment screw closed was unable to adjust unit 2. All systems are running properly at this time. Tech has attached system performance reports and pictures to this invoice.
Tech found wire not connected to ignition board Reconnected and tightened connections Heat and AC working correctly Told managers smell is oil burn off and smell disappeared while on site Thermostat is functioning properly at this time
