Arrived on site to perform spring tune up on a 2004 unit. Condenser located in back yard. Client stated no issues just wanted service and filter replaced. Cycled unit. Washed condenser coil inside and out. Checked electrical compartment and components. Found primary starter worn out and looks to be original. Recommend replacing due to burnt up pittings on contact points. Secondary is good and Lola to have been replaced. Unit added a compressor booster kit. Fan motor was replaced in past and is good. Start up amps are good and in place. Run amps are in range and pulling 11 amps max rated for 19. Checked pressure and are good and cooling home. Replaced filter and inspected indoor unit and ducting. Dusting is good and new as it was just replaced recently. Slight dust just need to stay on top of filter more. No protection on either unit. Recommend adding surge protectors on unit to protect from electrical and power outage and more cause of the condenser dose not have any disconnect and hi
