Upon arrival spoke with customer and explained what we would be doing today. Went to attic system first. Coil was clean, it has been replaced before. Blower is clean. Coil no leaks, system inside is working good but no drain safety’s. Went downstairs. Found coil was frosting up and was rusted and leaking. Showed customer and we called for a territory manager. Blower was clear, heat exchanger checked out good. Went outside, attic outdoor, contacter and capacitor checked out within specs. Fan and compressor checked within specs. Refrigerant pressures are within manufacturing specs. Crawl outdoor, pressures where extremely low, and compressor Megohmed green but is showing a little wear. Got options for customer.
