YAHVAC thread

(Yet Another HVAC) thread.

So uhm. I work in a hot warehouse. Drive home in a car that has no AC. Get home to find my apt scorching hot. All this under the Florida sun. I can repair computers, cars and other crap but HVAC stuff is totally out of my element. Hopefully I may learn a thing or two based on the responses here.

As I mentioned previously, I live in an apartment complex. I would usually call maintenance to come have a look at it, but they're all off their shift. The AC unit is on the roof (don't ask) So, I have no direct access to it. I tried to "reboot" it by shutting off the inside unit switch, the circuit breaker and the ac control and it tries to turn on, but only for a few moments, then shuts off.

Sometimes, Ill find the inside unit fins (after the air filter) would freeze solid along with a copper tube coming from the roof.

I also hear the inside unit makes a constant hissing noise. Not a leaking type noise but the same noise you hear when its about to turn on. In my case, it doesn't.

So that's it. Let me know if there's anything I could do to fix this. Otherwise, Ill probably end up drowning in my own sweat as I sleep tonight.

Thanks.

certainly you should be able to contact the maintenance to come out afterhours.

 

[El Guaraguao]

Actually, you're absolutely correct. Just learned that there is, indeed, an emergency maintenance crew in my complex. Should be here soon.

Bout to say most places have that. Mine broke down a few weeks ago and emergency maintenance (2 guys) were out here in about 10 minutes and the repair took about an hour (whole new outside unit).

 

[El Guaraguao]

Apparently having a broken AC is not an emergency. So I have to wait till 8am tomorrow to go bitch and possibly smash something at the office.

This is how I feel right now. http://www.youtube.com/watch?v=G7LrMoLba0c

Yep, straight down to the fan that JUST broke.

Iceing Evap - Dirty filter, Dirty Evap coil, or Low Freon. My first thoughts.

.

 

[El Guaraguao]

The filter is pretty much new. The evap coil fins look clean, should I open it up the unit and see if theres more dust anywhere? Before I open it, I would shut down all power to it for obvious reasons. As for the Freon, that might be the case.

 

[weadjust]

Let it thaw out and then try turning on again. May work for a little while until it freezes again. May not work but worth a shot.

 

[El Guaraguao]

Yeah, I let it thaw out. Rebooted the power and still freezes and shuts off. The copper pipe starts to freeze pretty quick too.

 

[El Guaraguao]

Yeah, Im pretty much convinced my unit needs more Freon\coolant. I managed to get my fan working, so Ill doing it third world country tonight, heh.
