Upon arrival homeowner informed me that he feels like the AC never shuts off. Checked refrigerant levels Suction line PSI 128 with saturation at 44 degrees and Liquid line PSI 368 with saturation at 122 degrees which is good. Checked static R: .6 and S: .4 which is higher than manufacturers specifications. Went inside of home and found dirty air filter because they have been doing remodeling on home, took air filter out and put one of company supplied air filter and retested static and R: .28" and S: .3" which was good. I noticed when I arrived that thermostat was set to 68 degrees and it was 75 on thermostat, homeowner informed me that they just turned the AC on and I told them that they need to set it to a temperature and leave because it makes the system work that much harder to try to catch up to temperature because everything in home will heat up. While there it did go down 3 degrees within in the hour but seemed to run longer than normal I found fan was on recirculating mode and
