WO-TNFR651552 I conducted a comprehensive warranty repair and club rejuvenation cleaning on a Daikin ductless mini-split system. The process involved recovering the existing refrigerant charge and replacing the outdoor compressor and main electronic control circuit board. The system was pressure tested at 450 PSI and found leak-free. A triple evacuation procedure achieved a vacuum level of 500 microns. The system was recharged with R-410A refrigerant to the specified 2.08 lbs. Performance testing in cooling, dehumidification, and heating modes showed a 23°F cooling differential and a 28°F heating rise. Electrical connections were verified, and the indoor coil was rinsed and cleaned. The condensate system was inspected for proper drainage. The system is now operating normally within specifications.

Upon receiving a complaint about the air conditioning system not cooling, I conducted a thorough inspection. The customer had previously had the system charged multiple times, but the issue persisted. During my assessment, I identified several problems within the refrigerant system. I presented the customer with repair options and explained the potential benefits of each. However, the customer expressed a desire for further consultation with one of our comfort advisors to explore replacement options. I provided the customer with our best repair recommendation and discussed all available alternatives in detail. This ensured the customer was well-informed and could make an educated decision regarding the next steps.

I conducted a thorough HVAC rejuvenation cleaning, including inspecting the air conditioning system. The blower wheel was clean and spinning freely. Static pressure was recorded at.98 in. w.c. with a 23°F Delta T. The voltage distribution system was below spec with 10 ohms of resistance and pitted contacts, so it was replaced. The refrigerant pumping system passed the megaohm test, but the LRA was above spec, so a performance enhancement system was recommended. All electrical connections were secure.

So to the good from a customer service representative experience. After the issues experienced with the first technician I called in and spoke to the service coordinator who within an hour had a service manager on his way to correct the problems of the 1st technician. Paul came out went through the system and completed what we needed as far as cleaning and tune up. Paul took the time to test everything and even discuss questions regarding filter sizes and efficiency questions. Paul resolved what started the day with an absolute negative experience and restored our faith in Moon Air to do the right thing and do the job right.

Greg came out as scheduled. Beyond that the entire experience was less than desirable. He serviced the wrong unit and when it was brought to his attention that he was servicing the wrong unit he made it appear as though he corrected the error and cleaned the correct unit. Technician left with the burner and heater still running with notes stating the thermostat relay needed replaced and notes of needs for the unit we do not use nor have ever had serviced. Sadly this was not a good experience at all.
