Complete 1 system a/c repair and preventative maintenance check. Did not change the filter. Tested mechanical and electrical components. Found weak blower capacitor (7.5uf), recommend a repair. Found system with no overflow protection switch, recommend adding on to serve as a backup to pan water safety switch and to help protect furnace from potential water damage. Tested refrigerant pressures. Recommend hard start kit to take a load of the compressor so it starts smoother, runs smoother and therefore lasts longer. Recommend surge protection to protect equipment from power surges. System is cooling at this time. Thank you so much for your business today!
