I arrived at our clients home for a 2 system maintenance inspection. Our client had recently replaced his air filters and did not need them changed today. I began outside by testing the electrical components for both outdoor units. Almost everything passed inspection today with exception of the upstairs capacitor and both units had very high start amps. Both units already have compressor savers attached. After washing the outdoor coils it did help reduce the start amps for the units. But this is also normal to see with units this age. I proceeded upstairs to the attic and checked the temps true split and blower motors for both units. Both indoor blower wheels have significant dust accumulated on them. We discussed cleaning blower wheels as well as replacing the capacitor but our client would like to monitor them at this time. Both units are have the exterior fan motor also working relatively hard according t9 manufacture specifications.
