Kenwood Central Air Conditioner

You dont just add "GAS" to an a/c. First thing to do is to trouble shoot the unit!! When you turn the thermistat clock wish is it clicking ?? if not maybe its bad or open. If it is then turn the thermistate all the way to the left, turn on the A/C to cool. Then slowly turn up the thermistat and see if you hear the compressor comming on and staying on?? If you dont and you will if its working then you have a bad start cap or a wire is burnt off one of the terminals or the click-on inside the wireing cover is open.. Now if it starts and shuts off it could just be a capacitor or even the compressor its self. Iv'e use window shaker type a/c and repaired them for years in NYC and seem some really old ones that were condistion as these older units have copper cooling coils(eveporators) and copper exhaust coils(condenser coil) in the back and the front of the unit. Now days most manufacturers use aluminum coils and I think there garbage as they dont hold a charge for a long peroid of time and they glue them together. so remember thid\s when your looking for a replacement unit as it wont last but a few years if its aluminum!! Good Luck
