AC repair completed in Stafford today on a Lennox system that wasn't cooling properly. Diagnostic testing showed multiple issues: failed capacitor reading only 31μF (should be 45μF), refrigerant pressure significantly low indicating a leak, and condenser fan motor drawing excessive amperage. Replaced dual-run capacitor with OEM equivalent and installed new heavy-duty condenser fan motor after confirming bearings were failing in original. Located refrigerant leak at Schrader valve core and replaced it. System required 2.5lbs of R410A to bring to proper charge. Also found disconnected condensate safety switch which was reinstalled and tested to ensure proper shutdown if drain line clogs. All electrical connections checked and tightened. System now cooling efficiently with proper temperature drop across coil. Homeowner very relieved to have AC working again with our same-day service during this heat wave! Left detailed invoice with 1-year warranty on all parts and labor.
