Upon arrival filter was clean. Went over indoor with customer, coil is rusted and found leaking. Blower is alittle dirty. Wires all tight. Drain is clear but no drain safety’s. Showed customer the return and how it chokes down as well as a return he didn’t know about. Went outside, system is low on pressure, fan amped at .9amps. Compressor is running at 5.56amps, run load are 18.7amps. Megohmed compressor and it is green. Coil is alittle dirty. Lineset size is correct but where it goes threw the wall there is no protective sleeve. Showed everything to customer and explained the issues. Recommend replacement of indoor unit, lineset and fixing the return. Sent customer emailed copy of membership form to look over as well
