At arrival on 09/05/25 Issue: no cool System: whole home Finding: system was cooling at arrival except for the bypass damper that was not opening all the way. We opened the bypass damper and total static pressure went to 0.61 with return 0.15 and supply 0.46. There was some trace of water on the supply plenum at arrival. There is no wet safety switch, no ss1 safety switch, the drain line has an unnecessary U shape P-Trap which could cause obstruction to water flow. Dirty condenser coil, low subcool. Recommendations: Gave option to correct all of that and clean drain line as well. After cleaning the condenser coil. We checked the pressures and the pressures were reading good. No need to add any refrigerant. System is cooling properly at this time. Please credit $224 to homeowner because we did not need to add any refrigerant after cleaning up the condenser coil.
