Arrived on site to perform spring tune up on a Rheem unknown age of unit original to home. Condenser located on side of home. Furnace and Evaporator coil located in attic. Client stated he knows system is old but is still working good. Cycled cooling washed condenser coil inside and out. Unit really dirty from lack of maintenance in previous years. Primary control is burnt up and black on pittings and is going out. Secondary motor controls is below range and bad as it’s weak and will keep on getting low. Recommend replacing before completely fails. Compressor started up are at Max. Recommend a compressor booster kit to help reduce high start ups and prolong compressor life. Fan motor has been leaking a lot of oil and bearing are starting to seize up and is working hard. Motor pulling 1.1 and unable to find what’s it Max rated for as condenser unit has no information. Unit uses R-22 and is no longer around. Pressure are good. And cooling home at 20 degrees. Inspected indoor unit
