The ac unit does not turn on but when we turn on the unit from the house something is running, but when we go out back that unit is not running at all. SInce the house was vacent for some time we are thinking maybe someone switched it off but i have no idea how to check any of these things. WE checked the fuses and everythig is fine. We called the landlord and have not heard anything back.. When we turn the unit on inside the house we hear soemthing but it is not the AC

the vents are not blowing air and all the circuit breakers inside the house are switched to the "on" Posistion.

Check around the outside fan part. There should be a metal box, about three inches wide and six inches high. Inside that there's a black square thing with a handle.
TURN OFF THE AC FROM THE INSIDE, then yank really hard on the handle of the black thing. The black thing will come clear out, and on the back of it you should see a pair of fuses. They usually have copper coatings on the top and bottom. Mine are the size of shotgun shells, but my sister's house (which is smaller) has ones about an inch tall each.
If you've got a multi-meter, you can test them to see if they're broken. Switch it to ohms. Click the red and black together (without a fuse) and you'll see what sort of resistance a circuit with current going through it gets. Take them apart, and there is no circuit to test.
Now put one on one side of the fuse, and one on the other side of the fuse. It doesn't matter which. If the fuse is still good, there will be a circuit, with resistance similar to clicking the red and black of the multimeter together. If the fuse is bad, there will be no current. Get new fuses if either one is bad, and then put the box back in right.
This outside thing on the porch sometimes gets clogged like a radiator, it will build up a lot of dust that makes it work less efficiently, and that can strain the fuses... and increase your bills!
When the system is off, and the fuses are out, get a hose around, and spray down inside from the top. Spray on the fan, and aim around at the otusde. Then spray the sides of the thing down all over from the outside. Yuck! all sorts of brown goop will slosh out. You can unscrew the fan cover to get out stuff that piles up inside too.
Hope that helps.

Are the vents blowing air? Somesystems have TWO circuit
breakers , one for the compressor unit and one for the blower fan. Check your circuit breaker panel
Usuall behind a door or in a closet. And make sure they are all flipped on. Some units have a disconnect
box outside with the unit. the newer ones are circuit breakers, if it is off, flip it to the on posistion.

It is possible the indoor unit has a belt from the motor to the fan that is broken. And maybe someone has removed fuses in outdoor unit. Or possibly with the belt broken and outdoor compressor continuing to run the compressor is now bad. Turn off all power to indoor unit and remove cover to see if there is a belt broken. Then check outside for blown fuse in power panel. Some more expensive units will automatically shut themselves down if the pressure gets too high on the compressor and you have to remove power to unit to reset.

On the outside of the house next to the ac there is a circuit box check the fuse out there. pull it out and flip it over then try the air. When we moved into our house it was winter and the builder put it in that way so the air could not be turned on in the winter.

The AC unit has two assemblies. The compressor unit which you see outside, and an expansion chamber inside the house...most likely in the attic or in a closet. This inside unit has a fan which circulates air from your house across the cooling coils. What you are hearing is most likely the inside fan.

you may have a refrigeration professional come to exhibit screen the instruments and verify their EER rankings. in the adventure that they are older instruments, they gained't carry out as effectively as will more moderen instruments, even inspite of the undeniable fact that they are operating actual. besides, electricity utilization is determined by how properly insulated is the abode and how cool you need save same.
