I have a 2007 Chevrolet HHR and recently noticed that after the air conditioner has been running for a while it will alternate between ice cold air to very warm air. Could the freon be running low?

The air conditioner in my home seems to be blowing cold air, it feels cold anyway. But our thermometer doesn’t get below 80 or higher. I checked the filter and replaced it but that does not do anything. Can anyone clue me in on anything?

My air conditioner used to blow air fast, now it is very low. I can barely feel the air coming out of the vent. A few weeks ago the air froze and we had freon put it in, but it still blows air very slowly and it stays warm and humid in the house. The vents feel cold to touch, but its not

So lets say you want to air condition a room. But, the room has no window to put an air conditioner in. Is this at all possible? Like, is there any type of air conditioner you can set up in a room, without using a window? Thanks.

How does an air conditioner, and a heater work? I’ve always been curious about it, plus one of the vents is leaking water, :\ and I always wanted to know how an air conditioner uses water.
