Newport NC Heating & Air Conditioning Services

Upon arrival tech was informed system for office was running continuously and blowing hot air. Inspected system and found the relay on the blower control board was shorted causing the blower to engage which also caused the heat strips to come on. Installed a new relay in air handler and tested heat and cooling operation and system is back operational. System is not cooling the best, it is a R22 Freon. Recommends replacing system due to age and Freon type.

Performed ESA on (1) Mitsubishi Mini Split system. All (3) zones working properly at this time. Cleaned all filters/coils, cleared drain lines, and re-secured line-set covers shown in pictures.

- Customer informed tech that the crawl space has excessive moisture, despite 4 dehumidifiers and 2 pumps. - Customer informed tech that their crawl space encapsulation contractor is scheduled to visit next week. - Tech informed customer of all these issues and recommended course of action. Tech examined crawlspace and discovered the following: 1. Trunk line and numerous flex supply ducts are resting on the ground. The insulation and jackets are saturated and should be replaced. 2. Line sets are not insulated and are contributing to moisture issue. Checked drain lines and flushed/vacuumed both drains. 3. PVC drain outlets discharge water onto a downward slope, pushing the water back into the foundation of the home. 4. Dehumidifiers do not seem to function correctly. Course of action: 1. Hire landscaper to install a perforated drain system to direct drain discharge away from home or re-grading slope away from the home. 2. Hire crawl space contractor to remove current standing water

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.

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
