When AC is blowing warm air, the most common cause are low freon levels. Due to the lack of freon, there the freon expansion (turning it from liquid to gas) is not sufficient. That means the cooling coil will not be adequately cooled; in fact, it might start to become warmer the longer we run the AC.
How do I fix my AC blowing hot air?

Are portable air conditioners supposed to be hot?
During air cooling process, a portable air conditioner creates hot humid air that is usually directed outside or somewhere through an exhaust hose.

Why is my air conditioner running but not cooling the house?
Condenser Unit is Blocked If your air conditioner is running, but not lowering temperatures inside, one issue could be a blocked or clogged condenser coil. When operating correctly, the condenser fan draws air into the outdoor unit through the condenser coil to pull heat energy out of your home.

How long does it take for a portable air conditioner to cool a room?
In our AC tests, we measure how long it takes a portable air conditioner to lower the temperature in the test chamber from 90° F to 85° F. It takes at least 20 minutes—and often much longer. By comparison, the best window air conditioners can cool the room by 10° F in about 15 minutes or less.
Why does air rise and fall?
When we heat air, the molecules jiggle and zip around faster, which causes them to spread out. When a mass of air takes up more space, it has a lower density. When you have a lower density fluid immersed in a higher density fluid, the lower density fluid rises and the higher density fluid falls.
What happens when the temperature of air cools?
Air is made up of molecules that are constantly in motion. The opposite effect happens when air cools. As the temperature drops, molecules move more slowly, taking up less room. The amount of space the air takes up shrinks, or reduces the air pressure.
How long does an RV air conditioner last?
