I conducted a comprehensive preventive maintenance check on three air conditioning systems. This included blowing out the drain lines, inspecting and replacing air filters with the customer's assistance, and testing the condensate pumps. The condenser was rinsed, and I checked all electrical connections, pressures, and temperatures. All systems operated correctly. In the in-law unit, I identified low refrigerant levels, adding 10 oz of R410a to achieve optimal subcooling. The compressor side capacitor was below the manufacturer's rating, so I replaced it with a new one. After installation, I started and tested the system to ensure proper function.

We conducted a comprehensive maintenance check on the air conditioning systems. This included performing two preventive maintenance checks, inspecting the indoor evaporator coil and blower compartment, and ensuring all electrical connections and safety features were operational. We measured voltage and amperage, examined the air filter, and rinsed the condenser coil. The drain line was cleared, and the condensate pump was tested. Refrigerant levels were checked, and the capacitor was inspected. Temperatures were taken, and thermostat functionality was verified. We identified a slight refrigerant decrease in the main floor unit and added 8 oz of R22 after authorization. The second-floor air filter was found to be heavily clogged, potentially causing hair to reach the coil. We recommend monitoring the air filter and considering a unit replacement for the first floor due to rising compressor amp levels.

During the service, I thoroughly inspected the wiring and valve systems. Upon examination, the main house zone valve's stem was found to be partially depressed, preventing it from fully closing. Despite attempts to manually push it down, the valve remained unresponsive. With the valve in a partially open state, it was inadvertently closing the end switch, causing power to be sent back to the boiler and initiating its operation. Given the valve's condition, it is imperative to replace it before the onset of winter to ensure proper system functionality.

Upon inspection, the zone valve for the main part of the house was found to be open, even with the thermostat removed. The power head was disconnected, but the valve remained open, indicating a faulty power head. After replacing the power head, the valve opened when the thermostat was turned on but failed to close when turned off, suggesting a short circuit. Despite the thermostat being disconnected, 24 volts were present at the valve terminals. Tracing the wires, a section was replaced, but the issue persisted. Further troubleshooting is required, and the power head will need to be replaced again.
