I arrived at our clients home for a two system cooling maintenance inspection. I began by replacing both air filters in the attic. I then proceeded outside to test and inspect the electrical components for both outdoor units. I found the downstairs unit capacitor, and contactor to be near failure. I showed this to our client and he elected to replace both of these components under warranty after the repair was completed The compressor start amps were still exceedingly high. I showed our client the advantage of having a hard start kit with the reduced amps. He declined to have this added to his unit at this time. I did wash both outdoor condensers as part of maintenance. Then proceeded upstairs to inspect the blower wheels for both attic units. Both Have dust accumulated on the wheels. I showed this to our client and he elected to monitor them at this time. Both units are cooling on departure.
