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.
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. System is likely in need of demand tech to diagnose. Thermostat is not blank but shows low battery warning.
-Performed CMA Full Service on 9 Split System Heat Pumps and 1 Dehumidifier. -Office Building System: Compressor side of dual run capacitor tested very weak. No room to add additional capacitor, recommend replacement of dual run capacitor. System is over 20 yr old R22 refrigerant. Customer should consider replacing system. -Building H: Dehumidifier run into existing drain line. Vent on wrong side of trap. Recommend adding EZ Trap to properly vent and service drain line. -Building J: Blower motor capacitor tested weak. Recommend replacement of capacitor. Outdoor fan motor hot to the touch. Compressor megged as caution. Windings deteriorating and due for shorting/failure. Signs of heat damage at condenser unit wiring. Temperature difference in cooling not as expected. Air handler approximately 20 yr old. Condenser approximately 30 yr old. R22. Replacement of system is recommended. -Building L: Compresso
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
