Upon my arrival to lockhart, tx., i found that there are two ac systems, and Older unit and a newer Goodman system. Found that older system is in bad shape and needs a lot of maintenance on it, the indoor heat transfer media is dirty and the outside system is too, the starting components are in rough shape and need replacing. On the newer system it also need a cleaning and attention to the outdoor system. Called customer and explained to him findings, he would like a estimate for a new system.
