Replace the 4 inch filter that wasn’t standard for us to replace however, I did it for Sue Travis this time as she knows that in the future, the 4 inch filter is an added cost Cleaned out the platform inspected the wiring, harnesses and electrical connections verified proper voltage and amp draw system is working great at this time. We will be back in the spring to do the outdoor air conditioning cleaning as that will be the last visit. Need to renew next time we go out there for the air air-conditioning heating for preventative maintenance.
