Completed comfort call inspection of residential HVAC system located in basement utility closet. Documented existing furnace unit and associated ductwork, plumbing, and electrical connections through photographic assessment. Equipment shows normal operational wear with dust accumulation on surfaces and components, consistent with standard residential use requiring routine maintenance attention.

I successfully replaced the refrigerant pumping system, ensuring optimal performance. The old system was carefully removed, and a new, efficient unit was installed. I checked for leaks, calibrated the system, and tested it to confirm proper operation. The job was completed with attention to detail, ensuring the system meets all safety and performance standards.

Work Order (WO) TNFR651557 involved the replacement of the electronic control circuit system. The process began with a thorough diagnostic assessment to identify the faulty components. Following this, the old system was carefully dismantled and removed. A new electronic control circuit system was then installed, ensuring all connections were secure and properly configured. Post-installation, extensive testing was conducted to confirm the system's functionality and reliability. The job was completed efficiently, restoring optimal performance.

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 cleaning and inspection of the air conditioning system. This involved cleaning the evaporator and condenser coils, and the unit cabinets to ensure optimal airflow and heat transfer efficiency. All electrical connections were inspected for security and defects, with no issues found. The condensate drains and safety controls were tested and verified. The system was operated in both cooling and heating modes, with a ΔT of 23°F. All components, including the heat exchanger and air distribution system, passed tests. The outdoor unit was also inspected, with all voltage readings and devices within acceptable parameters.

During the inspection of the AC system, I thoroughly examined its components and performance. Despite its age, the system is operating efficiently and remains in decent condition, ensuring it will likely last through the summer. I highlighted the benefits of becoming a Gold Club Member, which includes two visits annually. Each visit involves a light cleaning and comprehensive testing of safety and efficiency, providing peace of mind before the heating and cooling seasons. The annual membership fee of $239.40 offers significant savings on potential repairs or replacements in the future.

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.

Performed a comprehensive cleaning and operational inspection of six mini split indoor heads and two outdoor units. Services completed today included cleaning all washable air filters, inspecting and testing condensate drain systems, and verifying proper operation in fan-only, heating, and cooling modes for each system. Electrical readings were tested and confirmed at 120V across all units. Temperature performance was verified with all systems producing proper supply air temperatures in heating and cooling modes. No error codes or fault codes were present at the time of service. Findings are as follows: Basement Solo System (S/N Y0501400) operated properly in all modes with return air temperature of 70°F, heating supply air temperature of 101°F, and cooling supply air temperature of 48°F. Office Unit (S/N E029591) operated in all modes with return air temperature of 71°F, heating supply air temperature of 101°F, and cooling supply air temperature of 43°F; however, the air distribution
