Spoke with customer over the phone about repair vs. replace. He is going to speak with his wife and contact us back.

Performed ESA, tech found leak in evaporator coil. Coil was also caked up and covered in nicotine. Tech cleaned off coil and informed homeowner of findings. Homeowner stated her uncle is the one that set up today’s visit and to contact him. Uncle is Terrell Marshall 443-472-3895. Field supervisor is to contact Mr. Marshall to inform him of his options.

UNIT #1 (300 WING)-4 TON TRANE SPLIT HEAT PUMP

UNIT #8 (DINING ROOM)- 3 TON TRANE SPLIT SYSTEM HEAT PUMP

Upon inspection on System #6 tech confirmed leak at evaporator coil on 2 year old system and will need to order new coil. System #7 has 215v coming into unit and 24v coming out of transformer but is not coming back through alarm relay. Alarm company needs to replace relay to get unit back running.

LINESET REPLACEMENT

Dropped off reserve tank of nitrogen. Left 01451 filter dryer.

-Installed EZ Trap on Air Handler 3 & 4 per prior approval. Insulated trap with insulating tape, cleared drain lines with compressed nitrogen. -Replaced 7.5 mfd outdoor fan motor capacitor on HP-4 per prior approval. Observed no status light at heat pump control board. Verified no voltage at heat pump by jumping Y and R circuit. Verified air handler disconnect in on position.

Upon arrival tech began inspecting GP #2 and found Circuit 2 contact had 2 burnt wires due to loose connections causing the contactor to fail. Tech replaced 3 phase contactor and Circuit 2 began working. Compressor amps and pressures were within range. System back operating at this time.

Performed routine maintenance per CMA agreement. 3 gas package units- Full Service on Kitchen, Inspections on 2 Dining Room Units, 2 Make Up Air Units, 1 DOAS system, 6 exhaust fans Challenges present - GP 2, upon starting the inspection, the technician observed circuit 2 was being called for, however, the compressor was not running. Technician shut off system, waited a few minutes and then restored power. Circuit 1 came on as normal. When circuit 2 was called for, the compressor amped to around 44, then went back to 0. Technician checked compressor to ground and got OL. GP 2 - on circuit 1 initially it was cooling properly, with a 18 degree delta t. During inspection, technician heard the reversing valve, seem to de-energize. Tech checked delta t and found it to be 0 as if system was not cooling. System continued running and then after about 10 minutes, the same noise was present and the system started to cool again. Tech assessed electrical connects and everything appears to be co

Tech inspected mini split and ran all 3 zones in heat and cooling. Ran each zone individually in heat and cool. ohmed eev’s, thermistors and checked all components on system and everything read within range. Tech reached out to LG tech support and they suggested it has a potential leak in the unit. Tech added 2lbs and 8oz of R410A to system to get them by for now and wanted us to return sometime next week to perform level 4 leak search and figure out exactly where the leak could be located. Homeowner gave tech key card for gate access and showed where key for house is located at. Tech returned to perform leak search. Leaks were found at the master bedroom evaporator coil and flare connections. The living room evaporator coil and flare connections. The loft bedroom flare connections. And the suction line for Circuit A at condenser. Tech recovered 3lbs of Freon with factory charge being 4lbs. Pressure tested with nitrogen and soap bubbles all flares and made repair at Circuit A suction a

Unit is 5 years old. Customer was wanting ballpark to replace multizone mini split (1 condenser with 3 heads) gave ballpark over the phone. Customer will think about it and let us know.

Tech found no trouble codes on display at the condenser unit or the airhandlers. Compressor did not seem to be operating, system had standing pressures. Tech opened up the compartment for the compressor and checked for ohm values and compared it to LG standards, which checked out okay. Tech cycled the power to reset the system and tested all 3 airhandler heads and it appeared to operate properly. Tech did catch the middle port starting to build up frost but went away after 10 seconds. Stepper motors of EEVs are operating properly, normal range of refrigerant levels were found. Tech turned off the mini split from the control thermostats and started them up in cool twice and system started up without challenges, Costumer has had multiple challenges in the past with this LG multi head mini split every year and is wanting a permanent solution, meaning replacing it with a Mitsubishi brand. Field supervisor will be notified and will provide a solution to the homeowner. Costumer requested to

Spoke with customer over the phone customer no longer wanted appointment said the single wide was not worth investing in new package system

Upon arrival tech was told 3 zone mini split was not cooling. Tech leak searched condenser coil and 3 evaporator coils and found no leaks. Searched all flare fitting outside with no leaks found. Tech believes one leak is located behind wall were the flare joint was cut and brazed together. Homeowner only wanted to clean filters and 1 blower wheel due to potentially wanting to replace everything. Tech installed leak freeze and 3.5lbs of R410A to get unit running for the time being.

Customer is going to see how long unit will last until replacing. Did not leave quote at this time.

Tech washed and serviced unit and found no challenges at this time. Tech put key back where it was under the condenser.

Performed CMA filter change. Tech replaced and disposed of all existing air filters. Also washed make up air unit filters, photos on file.

-Performed CMA Inspection on 11 split system heat pumps. -Split System 1: Compressor failed megohm test at last maintenance. Windings shorting and compressor likely due for failure. Compressor contactor dark and pitted. Recommend replacement of contactor. 2 pole 30 A. Provided estimate $270.23. Outdoor fan motor amperage slightly high. Outdoor fan motor capacitor tested weak. Recommend replacement of capacitor. Provided estimate $209.77. Observed melted connection at air handler high voltage wiring. Recommend installing split bolts at high voltage wires (3 phase). Provided estimate $172.41. Recommend rewire of heat strips using contactors. Further diagnosis of heat strips should be performed upon approval of wiring repair. System has been recommended for replacement. System should be left off at air handler until wiring repairs may be made or system replaced. -Split System 2: Found proper low voltage on R circuit coming from transformer. Circuit runs to fire alarm junction box then b

Tech found thermostat satisfied and system running properly. Refrigerant pressures appeared a little low, but outdoor temperature was 50 and outdoor temp needs to be at least 60 to get accurate pressures, subcooling and superheat measurements. Tech recommends coming back out on a warm day to diagnose refrigerant pressures. Thermostat satisfied at 76, return temp is 76 supply temp is 55. Tech informed customer to keep an eye on it and we will be back in February to do the maintenance

PERFORMED CMA FULL SERVICE ON 2MAKE UP AIR UNITS, 3 GAS PACK UNITS, 6 EXHAUST FANS, 1 DOAS UNIT, AND 2 HEAT PUMP CONDENSERS. ALL SYSTEMS PERFORMING PROPERLY.

Upon inspection of system number 6 tech found low charge as previously found, tech performed leak search on system after approval from Mr. Jeff. Tech found no leaks at evaporator coil or at condensing unit. Tech found lineset leaking at suction line. Looks like lineset is original to building. Will need to get quote to Lumenant to replace approximately 70ft of lineset. System is down for now, tech replaced 5MFD run capacitors on system 2,3, and 7. Billing out for todays visit. Photos on file.

Techs preformed CMA FULL SERVICE on 11 split systems. Split System #8 is down due to compressor being shorted to ground, tech recommends replacing system. Split System #1 is operating at this time but compressor failed megohm test, tech recommends replacing system. Split System #6 is down due to low refrigerant possibly caused by leak in Evaporator coil. Maintenance staff asked if system was under any kind of warranty. Tech told office will look into warranty information for system and advise luminant on solution for issue. All other systems are operating at this time but may be in need of minor repairs. Tech has attached estimates to invoice for any minor repairs needed. Tech also attached system performance reports to invoice along with pictures.

Tech was informed living room a/h was hotter then the rest tech did find living room a/h was furthest from condenser once tech turned a/h by its self liquid line would freeze up but when tech would add another a/h head liquid lines would unfreeze tech did that to each individual head and each individual head liquid line would freeze if no other head was on tech added 1lb of refrigerant to the living room head a/h started blowing out 49 degrees like the others tech was unable to get temps below 59 earlier until tech added 1lb tech got approval for leak search tech found a faint detection on upstairs bed room head tech spoke with customer due to how faint detection and tech could not pin point location of leak customer would like to wait to see how long it will take to leak enough to have issues arise again when performing esa in 6 months customer would like leak search again to see if leak is more present
