We have a 2-story house with 2 a/c units, one for each floor. The downstairs one isn't cooling house, so I looked outside and it wasn't on...go to fusebox and it's tripped...i untrip it and it trips again...what could be causing this? it's on its own circuit...house built last year (moved into in february), with new rudd units...any ideas?

Ok, I pulled out the disconnect next to A/C unit outside...then when i flip the breaker, it doesn't trip...so it's something to do with A/C unit broken or disconnect shorted? it can't be a faulty breaker switch since it doesn't trip if no disconnect in...so A/C repairman needs to come out...house is only 18 months old...if a/c not under warranty and i have to replace it, i'm not gonna be happy

You most likely have a locked rotor in the compressor.
You will need to call a reputable AC contractor.
If you do not know of one, contact the manufacturer, and they should be able to refer a good one in your area.
Good Luck

I just had the exact same thing happen...
Your compressor has gone out. When it is tripping the breaker everytime you turn it on, it is because the unit is trying to pull down too many amps at once. Before this was happening, were you finding that you lights dimmed when the unit kicked on? That 's usually a tell-tale sign that your a/c unit is struggling to run. With as hot as it has been these past few weeks, this is happening alot, as the a/c repairman that replaced my unit (sadly, I did not have a warranty) stated that he had replaced over 50 units in the matter of two weeks and had a waiting list that extended for another two weeks.
Find your warranty papers and call whomever installed it. If it less than a year old, then your compressor and labor to replace it should be covered.
****most new units have a 5 year warranty on parts, 5 to 10 year warranty on the compressor and a 1 year warranty for labor cost---check your home warranty paperwork for your warranty information on your HVAC units---if the house is new, you should be covered********

do the AC unit have fuised disconnect next to them?
if so try this...
turn off the 2 pole breaker at the main panel
turn off the fused disconnects in the OFF position ( usually down ), open up the disconnect, wearing dry leather gloves and with a cheap 7 dollar non contact inductance tester ( known as air wiggys ) check for voltage.. there should be none present ).. pull the 2 fuses out from the sockets holders , shut the disconnect cover, go back to the main panel, turn on the breaker...
does it hold or does it trip?
if it holds then your wiring from the panel to the disconnects is fine, the problem lies from the disconnect LOAD side to the unit it self.
Call a AC technician out to see if the compressor froze up, or to see if one of the 2 wires from the LOAD side to the inside of the AC terminal block was nicked and thus shorting out ( and I could tell you how to check for that,but for that you need a bit of experience to check things out. and a continuity tester. ) or if for some reason 2 wires are tied together from the LOAD side of the disconnect to the AC ( that would be a instant dead short )
turn the power off at the main panel that feeds the AC unit, go back the disconnect, open it , check for no voltage , and install the fuses back ).. now call the AC tech

how many circumstances are you going to interchange the breaker until now you're attentive to it is not a defective breaker? The A/C is pulling too many amps. there is something incorrect with it, no longer the wiring. Contactors are fairly a lot regular. If the contactor factors are rated at sufficient amps, the variety isn't significant. by way of fact the previous answer suggested, you relatively shouldn't have faith a random pal. you like a qualified guy or woman to do this. My wager is that that is low on freon, yet there are different motives? Does it cool whilst that is working? in basic terms curious, that is no longer a DIY interest.

There is a short in the wiring, or the compressor locked up. You will need a repairman to come out and fix it. Call your contractor and he should send someone out.
It will be under warranty. good luck.

Call the AC contractor who installed it. It should be under warranty yet. Don't keep trying to get it to work, you can make it worse.

UT OH.! when you go to trip the breaker back......do you turn it all the way OFF then ON.? If it still trips you have a short somewhere.....

trip the breaker all the way off
then turn it on
if it trips you've got a short, probably on the compressor lines

there could be a couple of things,you could have a short in the wires or your compressor wires are burnt,you should have a warranty from the company or builder.
