I performed maintenance on two gas furnaces, focusing on the AC components. The attic unit's delta T reached 22 degrees, with voltages and amps within range. The air handler and indoor coil drain pan were cleaned. The outdoor unit operated in cooling, and the coil was sprayed with water. The basement unit initially reached 23 degrees, and the filter was replaced. The outdoor unit ran in cooling, but a mouse nest was discovered, causing significant wire damage. The disconnect is off due to these issues, and a reschedule is needed for the defrost sensor replacement.

I successfully addressed a leak on the suction line of the unit located above the garage. After repairing the leak, I conducted a thorough pressure test to ensure everything was functioning correctly. I then pulled a vacuum to 390 microns to remove any moisture and contaminants from the system. Following this, I recharged the unit with the factory-recommended 5 pounds of R32 refrigerant. Upon starting the unit, I monitored the pressures and confirmed they were within the acceptable range, ensuring optimal performance and efficiency.

Upon arrival, the unit was found to be in a fault state, prompting a reset. After restarting, the suction pressure was measured at 37 psi. A leak search was conducted using 450 psi nitrogen, which successfully identified a leak on the suction line leading to the head above the garage. To address this issue, a return visit is required with zoom lock fittings for the repair. This detailed inspection and identification of the leak location will ensure a precise and effective repair process. For visual findings, please refer to the provided link.
