Upon my arrival in Smithville, for an air conditioning evaluation. I began by verifying system safety and its performance. I then flushed and treated the indoor water removal system. While servicing the outdoor system I cleaned the electrical cabinet and washed the unit using water. I had a few concerns regarding both systems today. I gave options to the customer to correct early stages of bacteria inside the main house unit, installing a performance enhancement system on the main house unit as well. Regarding the guest unit I recommended unit replacement due to the age being from 1996 and the air movement system bearings have leaked out oil, I have options to replace motor however customer would like comfort consultant to come out and give replacement estimate.
