One of my a/c blows air but not cooling. We left it on the other day and left for an hour or so. When we came back it looked like smoke coming out the top. After a moment of panic to get the dog out we found it was mist. What do I do now? I suspect the refrigerant was blowing out. |

I had a similar thing happen to one of my roof top a/c's. It turned out to be the start and run capacitor. Easy to replace and not too costly!
Don't know what the mist would be!

Bob,
IF it was really mist, it was oil and freon vapor from a cracked line which just happened. It could also be oil from the electrolytic capacitor which probably has a 1/4" rupture disc in the end between the connections. A quick diagnosis is easy: Set the fan on the lowest speed (quietest) with the thermostat at the highest temperature setting. Then turn the thermostat down until it clicks, and listen carefully to what happens. If the compressor starts and runs, you have a freon leak. If you hear a hum for about two seconds, then silence, the start capacitor probably blew. Capacitor is cheap and easily replaceable. Also possible that the compressor is locked, which would have blown the first capacitor, and will destroy the new cap. shortly. A locked compressor=a new unit.

Leaking freon isn't going to mist for very long..... From the time
of rupture, to you seeing it... welll.....
We had a Coleman build up with ice. The damned thing
looked like it was steaming outside. Of course, until we got
all the ice melted off the fins, it just blew hot air... Hopefully,
that's all that's wrong with yours? (not setting the temperature
too low while running the fan on high, solved the problem) |
