Please help I can't find the reset button and it is hot here!

Wall unit? If so, I would check end of cord.

Its not a wall unit it's a central air unit

Then I would check the inside breaker(s) and disconnects, you may have 2 breakers in the panel one for inside and 1 for outside unit. Then you should have 1 right next to each unit(inside and out), turn off, then ON

Please help i can't find the reset button and it is hot here!

Not having a model it would be impossible to try and guess, but its doubtful it has a reset button,, turn off all breakers,for a/c unit and furnace,then back on
Let us know if this helps
