My air condition keeps popping and cracking....why?

Question

when left running for a while our air unit starts popping and cracking and quits cooling what causes this?

Answer 1

try to be a little bit more definitive with your question.  Is it a window unit?  Is it a central whole house unit?  What is the model number?  When it pops and cracks, where does it happen?

Answer 2

It could be several things. You should call a repair man!

Answer 3

I am having the same problem right now on my 8 year old 10 seer 3 1/2 ton unit. My ac was popping and I found out it was the wires to the compressor. The tech told me that a surge or something melted the plug. The AC unit would trip the breaker due to he had straps keeping in on and not pooping off but that didnt work for long.  I am right now having him put on a new plug wire due to the melted rubber has opened the electric from touching each other and making it pop and all. I hope it was the problem. Mine is a all in one unit and I have a manufactured home.
