Air condition won't work

Remove spark plug. Then try it. Sometimes filled with gas.

I wonder if they shorted a wire a during install. That is where I would begin.

You are saying it causes the breaker to trip?( or was past tense?) sounds like there is a short somewhere. that's why nothing comes on

Make sure the fuel is fresh (not older than 30 days). Never use old fuel unless it has an additive such as "Stabil" in it. Remove and clean or replace the spark plug. Make sure it is getting spark. With the plug out, shoot a couple good shots of carb/choke aerosol cleaner into the engine. Reinstall plug immediately. Choke it and try to start it. If you can get it running that way, the normal fuel flow through the carburetor may resume. Any other number of things could be wrong, but the machine has to have 1. Compression 2. Clean Fresh Fuel 3. Clean Air 4. Strong Spark (blue color). Mostly, the problem with these is a fuel supply problem, which consists of the fuel filter, fuel lines, internal parts of the carburetor and condition of ALL sealing gaskets on the engine. Any air leak will result in a no start condition. There is no majic fix. The ethanol in the gas now wrecks havoc on these little machines. Check all the above. Try the carb cleaner and post back with results.

I will assume this is a central air conditioning system. From what you tell us about the symptoms a few things come to mind for you to check.

1. Change your thermostat and see if that cures your problem.
*The following steps requires the use of a multimeter and work around electricity, use due caution or call a professional.*
2. Check the contactor inside the outside unit while you have the thermostat calling for cool and see if it is pulled in or if it is stuck. If you are not comfortable around high amp electricity then please call a professional in your area to make these checks.
3. Check to see if the thermostat wires going to the outside unit are sending 24 to 28 volts to the unit. This will tell you if the problem is outside or inside the home. If there is no voltage there then check at your furnace to see if the t-stat is sending the power on the Y connection.

There is much more to check but this should get you going in the right direction and will locate the problem in most cases.
Hope this helps.

TEST YOUR ALTERNATOR AND HAVE THE BATTERY CHECKED IF THEY ARE OK
YOU MAY HAVE ELECTRICAL SHORT

Most of time it is a battery problem.... try with another battery, before purchasing new one....
If another battery does not works then get it serviced.
Battery has certain time period life (mostly it is expressed in, "no. of times charge") after that battery power deteriorates...
Or if battery has been water clogged then also battery power deteriorates.... (for water clogging may happens exposure of battery to humid conditions)
Please rate the answer if you find it useful...
thanks for rating....
