Here's a summary of the work completed: **Filtration:** * Checked the pleated 2-6" and pleated 1" filters. * Replaced the filters with the customer's spare 16x25 filters. **Electrical Components (Tested and Working):** * Verified proper operation and amperage of the blower motor, condenser fan motor, compressor, blower run capacitor, compressor run capacitor, fan run capacitor, compressor start capacitor, contactor, and electrical wiring. **System Components (Inspected and in Good Condition):** * Confirmed the blower wheel, secondary drain pan, primary drain pan, and electrical wires are secured and in good working order. **Condensate Drain System:** * Cleared the drain line. * Cleaned out the primary and secondary pans. * Tested the safety switch. * Verified the drain line is connected and strapped down. **Measurements:** * Return air temperature: 70.0°F. * Supply air temperature: 118.0
