The last thing I am is an A/C expert, so I told my wife I was going to where I knew the experts were. My inside unit of my A/C started making a clicking noise from the area that the power wires go into it. You can hear the clicking from across the room, ie. click, click, click, etc. It will click for maybe 30 seconds and then the unit comes on and from what I can tell the clicking stops. It doesn't do this all the time. Could it be bad contacts? I guess there are some in there. This is a Heat Pump unit.
Thanks for your help.
