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 are 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.

I'm not an expert on this, just have worked through my share of problems with HVAC.

I've had something similar happen when a relay was bad and needed replacement in at least two homes. Also had some issues with wasps getting into a box in another home...beat on it a bit and it started working again.

I've also had some similar trouble when the compressor was nearing the end of its life. It already had the largest capacitor for start up, and then it burned off a terminal block which had to be replaced. It would try to engage the compressor, fail, then try again a short while later.

Probably best to call someone out and do some quick maintenence, check the charge, etc.

If your thermostat has internal batteries, make sure that they don't need to be changed.

Yep, thought about posting the same, but haven't had a click associated with that, just a unit that either wouldn't shut off or wouldn't turn on no matter the indicated temp or set point.
