House AC Unit Still Sealed?

When it does, it is sucking up energy that is required to cause the liquid to gassify. An AC contains far more freon in the form of a liquid than it does as a gas. When the sealed freon loop is breached, the liquid freon returns to its' gaseous state, because it is no longer held under sufficient pressure to maintain a liquid state.

It most likely was not done "properly".

Many people don't understand that an AC works by boiling [gasifying] a liquid. When the high presser liquid freon goes to the low presser side it boils. Then it is compresed so when it goes into the condenser [radiator] it condenses into a liquid. When any liquid boils it is at its boiling temperature. At the atmospheric presser of sea level boiling water is always 212F Freon [R12] is around -22F. Just like when you heat the water, freon takes heat to boil, the heat is from the air in the room you are trying to cool down. So a boiling liquid is what cools the air.
