Why isn't cool air coming out when i turn on the air conditioner

You could be low on refrigerant. If you are familiar with automotive ac you can check this by renting a set of ac gauges and reading pressures. If you prefer to have a shop take a look, use this link to find a good one near you.https://repairpal.com/repair-shops Alex

Does the little *AC light* on the switch turn on when the ac is turned on on?
