Arrived at our clients home for a single system cooling inspection. Our client did provide a filter to be replaced today. Once replaced I proceeded outside to test the electrical components of the unit. Everything passed inspection today. I did also wash the coils of the outdoor unit and showed these pictures to our client. Both indoor and outdoor units are without surge protection. I proceeded inside and tested the supply temperature as well as the blower motor amps. The motor is reading high draw due to the dust collected on the wheel. I also showed these findings to our client and she requested an estimate for a drain pan replacement and a blower wheel cleaning. The unit is still operating and cooling properly.
