The clicking sound is usually the relays in the control unit making or releasing. When they click does anything turn on? Check the control unit that is located inside the lower unit of the air conditioner. Remove the cover and listen for the clicking sound. If it sounds as if the relays are clicking, try removing power from the thermostat and see if that stops it. There are three relays on the board, one is the compressor, one is the fan relay and the other is for heat. See if you can pinpoint which one is clicking and go from there. It is either that you have a bad thermostat or a bad relay board.

you need to clean this section of coils badly. Get a plant or weed sprayer. go to a a/c parts supply store and get some coil cleaner. Tell the staff that you need something to clean the coils on your a/c coil. Tell them what kind of a/c you have abd they will assist you in the purchase of the proper chemicals. Make sure to read directions for the use of the chemical and also wear all necessary protection equipment, i.e. safety glasses, gloves. Follow the instructions on the chemical as how to clean your coils. Once the coils are cleaned you still may need to have the pressures checked on your unit. It won't help to check the pressures on your unit when coils are dirty since that will give you false readings. So you need to start by cleaning the coils. Good luck Dave
