Do window untis own freon like a car's ac? I be wondering because the one in my house blow's hot nouns now. It's possible that if it does use freon it would be out because it be ran on illustrious for over a year straight, even in the middle of winter. And also, if they do use freon can it be recharged/refilled approaching a car or do I own to buy a new one?
Answers:    They do use freon, although, it is presently a less ozone depleating type than it be years ago. But it is hard to notify from a distance what the problem might be.

One common problem is if the motor starter capacitor for the compressor go out, so the compressor cannot start. When I bought my home, the window AC have been working fine, after suddenly the second summer, the compressor did not kick surrounded by. But it is glued into the top partly of a second floor window and does not own a slide out chassis, so I am using a portable upstairs (on wheels next to a dryer duct like hose). The one on my first floor is built into the wall and is still going strong since 1972 (I checked its serial#).

The seal in the compressor usually do not dribble unless an AC is NOT used for a long period of time and they dry out. But not sure what climate you live it that you run it adjectives year. It may not be good to run it if too cold out (unless it is also a steam pump).

One car I have got a pinhole freon dribble in the evaporator when the saloon was 2 years old-fashioned. But I have not have any trouble with the AC on a 13 year outdated service truck or 14 year old saloon (purchased new).

With all the pane ACs made in China, not sure if they are repairable or disposable (my city picks up appliances once per year surrounded by the spring).
all ACs entail freon, regardless if it is the car AC, pane unit or internal unit. You're right, if you are reception hot air you are probably out of freon. However, freon does not evaporate or disappear. You hold a leak somewhere and you want to call an AC repairman to find the overflow. Usually they can find it easily beside a colored dye which they place in the lines. the dye will come out of the connections or broken copper lines. They will replace O rings or fix your lines and imbue your unit beside freon and your good to step.
