If central air conditioner turns on but is not blowing through the vents, check the filter. If it is dirty, change it. Change the thermostat into cool, this will defrost the air conditioner.
Heat pumps have a reversing valve in the outside unit. You are hearing a balance of refrigerant pressures when the reversing is energized or de-energized.
The musty smell from your air conditioner when it turns on is likely due to mold or mildew growth in the unit. This can happen when moisture accumulates in the system, providing a breeding ground for these microorganisms. Regular cleaning and maintenance of your air conditioner can help prevent this issue.
you are blowing exhaust through the intake. It doesn't take a rocket scientist to figure out what that means.
An air conditioner works by compressing a gas into a liquid. This creates heat, which is vented outside. The liquid is squirted through a restriction and looses pressure and turns back into as gas, this has a cooling effect. The pipework containing this gas has a fan blowing over it and so cools the air and blows it into the room, or car.
many times it'd the run capacitor (that cylinder) where the wires from the fan run. if the fan is turned on and you hear a hum, tap the blade. if the fan turns, then that's the problem.
When the system shuts down the vapor turns back to a liquid
Your compressor is not working. Through evaporation compressors cool the evaporator coil and the fan blows air across it. So if the fan is blowing hot air the compressor is not cooling the coil. But check to see if the dial inside the fridge is turned to "more cold" , that turns the compressor on.

Sublimation is when a substance turns from a solid to a gas (or the reverse). This can occur when blowing on dry ice or in volcanoes.
There is a penguin in there and it throws ice into the air condicioning and the heat melts the ice and turns it into air.
