Blowing hot air when set to A/C is almost always a stuck blend door, dead blend door actuator, or a cracked or disconnected blend door actuator vacuum line. The blend door is inside the a/c ducting under the dash, but the actuator will be accessible outside the ducting.

Hi!
It
appears we have an Air lock scenario and you will need to perform a
system Bleed.
Park
the vehicle on level ground, when cold remove coolant filler cap,
start engine and leave to idle, turn heater on full and blower to
max. When engine reaches operating temperature watch and listen near
coolant filler, keep clear as gurgling and hopefully a boil over
should occur. Top up with very warm coolant and wait as it may do it
again.
Check
for heat inside vehicle if warm replace coolant cap but keep an eye
on temperature gauge as the ~Air lock may have moved on from heater
matrix/core so proceedure needs to be carried out again from COLD.

SOURCE: air conditioner blows hot air from dash
On most cars when you push a button or slide a lever to change your choice of location where you want the air to blow out louvers move inside the dash to redirect the air to your chosen location. When you switch from heat to AC other louvers move. These louvers are often powered by vacuum lines running from the engine. If one of these louvers is stuck or if you have a vacuum leak in one of the lines it may be causing your problem.
SOURCE: air conditioner started blowing hot air
your a/c compressor is not working.
you have to have the system checked by an air conditioning place or the dealer as to what the cause is.

Get your ac filter replaced. My car did the same thing for a year until I figured out what the problem was.
SOURCE: When I turn on the air conditioner it is blowing hot air.
heater core is going bad my dodge ram truck did the same thing for about three months then steam startedcoming out of the vents it was antifreeze i have not fixed it yet i just bypassed it for now cause its hot and i have to take the dash completly out to get to it, and yes my airconditioner was blowing out hot now immediatly after i bypassed it blows cold again.you have to find where it goes into the motor on both sides so follow the hoses from firewall then buy a 3ft hose to go from one side of motor to the other problem fixed! well that is you wont have a heater until you change the heater core
