Yesterday my AC started hissing. The noise is coming from around the area of the evaporator and is not related to the blower. It seems to only occur when freon is cycling through the lines. Leak/low freon condition?
How dangerous are freon leaks inside the home? Does it pose a heath hazard? Also, when the hissing doesn't occur (intermittent as of about 35 minutes ago), if I put my ear up to suction and intake lines, I can hear a little gurgling. Is that normal?
Thanks for the help. I rent and I'm concerned that my landlords fix will be to simply recharge it and I'm concerned about freon continuously leaking inside the condo.
On an HVAC board they mentioned that low airflow can cause issues. I went to check my filter and it was clogged. I was supposed to have changed it last month, but it was stuck in there and I was in a rush. I forgot to go back and get it. So I'll see if it runs smoother with the new filter installed.

Obviously, all of these are related and a snake is involved.

You win! That's the most ADD post of the day! And now I have Toy Story quotes running through my head.
Actually, it could be a good sound, that of refrigerant boiling in the evaporator. If the hiss is actually refrigerant escaping through a leak you won't hear it for very long.

The hissing stopped this morning before I left for work.
Well, I turned off the AC before heading out the door. We'll see if I have a comfortable night or a not-so comfortable night tonight.

Do you see a relationship between these two?
Setting the AC at one temp level and leaving it there is best for the system.
If out of the house for an extended time turnig it up a few degrees (72 to 76) is OK...
but don't turn it off altogether.

BTW, have you gotten those thermometers yet?
Haha. You know what I meant!
I have read so many varying account on changing the AC levels or leaving them at one level that its impossible to tell who was being truthful. So I did an experiment and set the AC to one level -- 72 -- for 50 days. I just paid my highest energy bill ever, so I certainly isn't more efficient to run it at a constant level all the time. My typical behavior before was to run it at 70 overnight and 78 during the day. I think I will go back to that model. I had also been told to leave the blower on 24x7 -- and that has turned out only to be a money hog. I get circulating the area constantly while I am cooling from 78 to 70, but then it can be turned off.
I am not sure what your intention was by suggesting the thermometers?? Were you suggesting I bypass the lockout?
In any regard, it intermittently hissed on start-up last night, but it cooled the air. This morning I awoke in a 78 degree house. Must be a leak since its still running, but not blowing cold air.
