Completed a system tune up found 19 year old system with good pressures and good capacitor and contactor. System does not have a hard start kit or any surge protection installed recommend hard start kit to prolong life of compressor by taking away a lot of power from compressor during initial start up. Also recommend surge protection to prevent all components in condenser from possibly over heating or blowing all together during a power surge. Also recommend apco UV light to kill and prevent any bacteria or growth from accumulating in house or ductwork. This will also clean and purify air and any unwanted odors in house. System is cooling.
