Upon arrival, the indoor temperature was set to and running at 74°F. I conducted a thorough leak search on both the outdoor unit and indoor coil using bubble and inficon leak search methods, finding no leaks. The Delta T was initially 16°F, with the outdoor unit showing 24°F subcooling and pressures of 390 on the high side and 176 on the low side, indicating a slightly overcharged system. With the system off, the ambient temperature rose to 77°F within 35 minutes. I removed 2.4oz of refrigerant until the subcooling stabilized at 11.2°F. After running the system for 15 to 20 minutes, I rechecked the Delta T, which improved to 19°F. The subcooling remained steady at 11.0°F, and the thermostat temperature set to 74°F resulted in a 1°F drop in ambient temperature over 15 to 20 minutes. The thermostat reading was 74/76°F. No fault codes or leaks were detected, and all system parameters are within normal manufacturer specifications.

We completed a comprehensive rejuvenation of the club system. This involved a thorough cleaning of all components, ensuring that dirt, debris, and any potential contaminants were removed. Following the cleaning, we conducted extensive testing to verify the system's functionality and efficiency. Our tests confirmed that the system is operating smoothly without any issues. We meticulously inspected each part to ensure everything was in optimal condition. No concerns were identified during our assessment. We will notify the office, and they will coordinate the next scheduled cleaning.

I meticulously documented the damages and dirt left at the job site by taking clear and detailed photographs. Ensuring no evidence of our work was overlooked, I collected a drop cloth, a duct cleaning remote, and various tools that were left behind. Each item was carefully gathered and secured, ensuring that the site was left in a clean and organized state. My attention to detail ensured that all equipment was accounted for and returned to its proper place, maintaining the highest standards of professionalism and efficiency.

Completed comfort call for customer interested in new HVAC system replacement. Documented existing equipment condition including older air handler with visible wear and dust accumulation, electrical panel with Cutler-Hammer breaker configuration, and current ductwork layout in mechanical room. Customer expressed preference for specific installation technician to perform future system installation work if proceeding with equipment upgrade.

Found faults with the voltage distribution system. Voltage distribution system contacts are severely pitted and rusted. Found incoming 208V–240V line voltage wiring is dry rotted and needs to be replaced. This condition presents a safety issue with the system. Electrical safety circuit fuses are failed and require replacement. Voltage distribution system also requires replacement due to the condition of the contacts and overall deterioration. Refrigerant pumping system readings: R2/C = 5.9 amps R2/S = 17.1 amps S2/C = 5.9 amps Refrigerant pumping system megaohm reading is below 20 megaohms, indicating a faulty refrigerant pumping system. Line voltage measured at 241V. Checked system for refrigerant leaks; no leaks were present at this time. System is NOT functioning at completion of service. System is obsolete, approximately 36 years old, and utilizes R22 refrigerant. Replacement of the voltage distribution system, electrical safety circuit fuses, and line voltage wiring is re

Water Heater Repair: Investigating a client's report of strange noises emanating from the water heater, our team conducted a thorough assessment. The examination revealed a sediment-laden tank as the root cause of the noises. Our technicians performed a meticulous tank drain, eliminating the sediment, and replaced a worn-out anode rod, ensuring not only quiet and efficient hot water production but also extending the lifespan of the water heating system. The client can now enjoy the tranquility of a noise-free water heater and the long-term reliability of their water heating infrastructure.
