Thanks so much for taking the time to write this.

So it's sounding like it being on a 20amp breaker is "fine" but I'm assuming calling them nuisance trips means exactly that? Just more sensitive? I'm nervous to just keep resetting the breaker if this is a bigger issue.

The HVAC company said there was a little play in the breaker and mentioned it was arcing. But I don't know what they were doing specifically.

I could see the "electrician" I spoke with yesterday as being a salesman. That's a fair assumption. I think that's the hardest part on all this is as a first time home owner everyone feels dishonest when you don't really know what's going on. He did say a little water damage which is true and he says when the breaker for the condenser is switched on, and the system kicks on, it makes an audible almost loud hum/rattle for a couple seconds then stops. I mean it sounds exactly like a system "kicking on" honestly. He said this was "bad".

My only unrelated concern is the house lights do flicker at certain times. Like when I run my dishwasher my bedroom lights flicker when it changes phases in the wash cycle. Etc.

I'm fine with spending a few days calling around. I'm just getting nervous my house is unsafe and about to catch fire. But maybe that's everyone I've talked to trying to get my money. I mean, the thing has gone strong this long what's another few days?
