Air Conditioning Question
 

So my A/C isn't blowing so cold. I went outside to make sure the damn thing was running and it is. However, I noticed about a quarter inch of frost built up on the fitting that hooks to the insulated tube (as I understand it that's the side going back into the house). I checked both neighbors and their A/C units don't have any frost built up.

WTF? Is this what's causing it to not run cold or is it a side effect of whatever problem I have?

I'm guess the thingy that makes the cold have come lose and is putting the cold to not inside your house. /tkcnut

Spray some Windex on it.

Huh? Either you're being serious or you meant to say "antifreeze".

Sounds like a leak, but that's just me. Once you figure it out and get it fixed, you can fix the AC in my car. :D

Your a-coil is frozen up. You are going to have to turn your heat on to defrost it. Pop open your blower enclosure on your furnace and have a look.

Should this be the problem, the coil is dirty and you need to take a shop vac to it, and also change the intake filter.

You have to change the air filter every once in a while. :)

I was gonna say antifreeze, but I thought that line from "My big fat Greek wedding" sounded funnier.

Antifreeze should be reserved for problems with animals, namely cats.

You probably just have a vacuum line loose somewhere..

You should have given that contractor the job. Let this be a lesson.

Do you have any ****ing cottonwood trees in your neighborhood? :cuss:

No. :)

Brock is probably correct. Most freeze-ups are caused by dirty coils not allowing air to pass. Turn it off, let it defrost and then clean the coils and the area being careful to not get water in the fan motor or other electricals in the area. And, yes you could have a leak or your charge is wrong or a couple of other things but cleanliness is usually the place to start (Both the coils and the filter)

Lucky *******, would you like one? I do think I at least stunted its growth though, finally. It has been an expensive RoundUp investment. :D I think I am going to try and get Tim over here with his gun to finish it off one of these days.

This happened to me once when I lived at an apartment...the maint. guy said to just shut off the A/C and wait for the frost to go away (thaw) and then turn the A/C back on at around 75 and slowly crank it down to your desired temp instead of going from 80ish to 65

Global warming,...but only at your house.

This would be outside in the A/C unit, correct? I went out with the hose and sprayed down the entire unit. There wasn't much dirt on anything.
Where is this filter? Are we talking about the large filter that I change every 2 to 3 months year round, just on the side of the heater?

Same here. Mine was caused because I only had one vent open (my bedroom faces west). That is a no go. Good luck. I gotsta have my A/C.

Is this a wall unit or a installed Central Air unit? If it is a wall unit, you will have a filter inside the front cover and the coils outside on the back. If it is a central air unit, you will have an air return vent with a filter somewhere in the house (maybe more than one if large house/unit) and your coils outside again.

Thanks man. I'm going to give it a little more time then try and crank it up again.

I have the A/C repair guy scheduled out here at 8am, so I just need to get it limping along tonight.

The coil in the furnace is froze up. Turn off the unit outside and turn the fan on in the furnace. Let it run to thaw out the coil. Probably get some water around the furnace. After it si all thawed out, check the filter and make sure the fan is running at high speed. If those are OK, you are probably low on refrigerant (R-22 probably) and need to add some. Have you ever had to add refrigerant to the system?? Also, make sure the outside coil is clean. Wash it out with water to make sure the coils are clean! Hope this helps!

Thanks for the info. I got it all thawed out and I can hear things moving in the tubing between the house and the outside unit again. I have it running and it's cooling some, but not much. I'm pretty sure that the A/C guy is going to want to recharge the f**ker.

Any guesstimate on how much to put in an A/C system sufficient to cool a ~2500sq ft house with LOTS of Southern windows?

A/C Problem
 

Been doing this for 8 years in the Apt. business, could be a few things, 1. Dirty Filter, 2. Could be under charged low on refrigerent 3. Over charged( this probably is'nt your problem, since you haven't had the unit serviced lately). I work on A/C units 8 months out of the year, here in Nevada. So pretty much seen it all. hope this helps.

Mine iced up last year.........the blower was ****ed up I had to have a guy come out and replace it and then it was fine.
