I meticulously cleaned the flue pipe and heat exchanger using a brush and vacuum to ensure optimal airflow and efficiency. The oil filter, nozzle, and strainer were replaced to maintain the system's performance and prevent any potential blockages. I thoroughly inspected all electrical connections and safety mechanisms to confirm they were secure and functioning correctly. Combustion and smoke tests were conducted to verify the system's efficiency and safety. The results showed an oxygen level of 4.5%, carbon monoxide at 16 ppm, and no visible smoke, indicating the system was operating within safe and efficient parameters.

Upon arrival, the unit was off. I inspected the indoor unit, finding the air filter and evap coil clean and in good condition. After turning the unit on, the indoor unit started, but the condenser hummed without activating. I shut off the power at the condenser and opened the electrical compartment. Inside, I discovered a mouse nest and chewed-up high and low voltage wires. I repaired two low voltage wires, one high voltage wire, and replaced a wire terminal. Additionally, I checked the capacitor, which was found to be internally open on both legs. With customer authorization, I replaced the old capacitor with a new one. After restarting and testing, the unit is now functioning properly.

Upon arrival, the unit was off. I began by inspecting the evaporator coil and air filter, both of which were in good condition. Next, I examined the condenser coil and discovered some dirt buildup. To address this, I rinsed the condenser coil with water to remove the buildup. After ensuring the coil was clean, I started the system with both zones running. I then found that the system was low on refrigerant. With customer authorization, I added 15 oz of R410A to the system, which brought the subcooling up to 14.5, within the manufacturer’s specifications. The unit is now functioning properly. Additionally, I recommend installing a DATS discharge air temperature sensor at the zone panel. This sensor will shut off power to the condenser when low air temperatures are detected, preventing ice buildup on the indoor coil, a common issue in zoned systems when only one zone is operating at full capacity.
