I conducted a comprehensive AC maintenance service, starting with the replacement of the air filter using the customer-provided Air Ranger filter. I meticulously cleaned the coils and rinsed them to ensure optimal performance. Additionally, I inspected all electrical connections, voltage distributors, and the compressor, confirming that everything was functioning normally. The ductwork, recently installed by our team, is in excellent condition. The unit is a 16x25x1 model, and all components are now operating efficiently.

Job WO-TNFR655366 involved a thorough cleaning and inspection of an air conditioning system. The evaporator and condenser coils, along with the unit cabinet, were meticulously cleaned to ensure optimal airflow and heat transfer. All high- and low-voltage wiring and electrical connections were inspected for security and visible defects, with all connections found to be secure. The condensate drain and safety controls were tested and verified for proper operation. The system was run in both cooling and heating modes to confirm functionality. The filter passed inspection, and the thermostat terminals were at 25V. The heat and power storage devices passed, as did the air distribution system. Voltage enhancement and power storage devices were also tested and passed, with a minor issue found and resolved in the 40mf power storage device. Duct cleaning and aeroseal duct cleaning are scheduled for a return visit.

I performed maintenance on two gas furnaces, focusing on AC components. Both units were inspected, with filters checked and found to be in good condition. The first unit did not achieve a 20-degree delta T, capping at 12 degrees despite running for over 15 minutes. The indoor coil had significant rust, and a level one blower cleaning was conducted. The second unit had a 5-degree delta T, with the indoor coil also heavily rusted. The blower passed a tissue test, so no cleaning was done. The outdoor coils were cleaned with a coil cleaner and water.

No AC. Unit out on fault at the heat pump. Customer had the wrong filter type in the unit and had a mess cover over top the outside unit. He said he was told it was ok to do so. In a normal situation with a normal unit you can do this. And its highly efficient, so anything hinder its efficiency. The unit will protect itself and go into a fault. Removed the filter and mesh cover. Cycled unit multiple times to make sure it would shut on and off. No faults. All operations running normal. 20 delta t. Advised these calls that are related to maintenance can be chargeable. Made him aware of the filter type (spun fiberglass merv 4/30day cycle frequency to change them.
