I have a Yorkville Diamond 90 installed in my home. The air conditioning is somewhere between cold and lukewarm... definitely not ice cold. It's now 81 degrees in my house and it's not moving downwards, and won't until the sun goes down. The house is only about 4-5 years old. I know that I'm supposed to clean the coils on the inside unit... well, the installers sealed up the thing real good with silicone, etc. and didn't leave a manual. I can't see how in the world to get to the coils to clean them, or even if that's what's wrong. I know where the coils are, but the way to get to it is so small that I don't know how I can effectively clean it. There is also a small amount of water leaking from the one drain hole that doesn't have a pipe attached to it... just a few drops every once in a while. Can someone please give me a hint on where to start? It pisses me off to think that I'll have to call back the installers and have them charge me $60-80/hr. to take several hours of their time dismantling the whole AC unit for a simple cleaning. If need be, I can take pics to show the situation, whatever it takes. We're going nuts in this steamhouse.

well.. is yer air filter clean? if not,, that equals dirty A/c coils. Also even if the lwo side is cold you may be low on refridgerant! granted this could also cause things to frezze up(ice over) but youd notice a drop in air flow then, id say your coils are dirty,, they need to be cleaned,, ya need to change that filter once amonth(if its a cheap one) and have the pressures checked on your unit!, you could have a small leak, if they come to ""fix"" it make sur ethey do it right,,not just show up,, drop in a said amount of refridgerant and charge ya 80$,, have them find and fix the leak,,it may cost more,, but do it now you wont have to have it re-charged 3 years or less down the road! id go more into what goes into cleaning the coils and other a/c BS,,but since ive been on a roof all day,, fixing other folks units im kinda not into tapping into my brain right now,,,, give me 3 more beers and a chance to cool off and i may ad dmore down the road! |

Is this a new house? If so, then you may have been screwed, HEREs waht happened to me, I had a house built in 1998, the HVAC guys installled a AC/heat sytem, the only thing is, they undersized the outside condensing unit. So, my house would not be cool in the summer it did what is happening to you, the temp would climb during the day with the AC on, never shut off, and only start to cool down when the sun went down. I called the builder who called the HVAC guys, who told me flat out, I needed to UPGRADE to a larger system. Well I did, but not through them. I found out from a buddie of mine who does HVAC work, that this is a standard practice among alot of HVAC guys on new construction, to undersize the AC system, home owner then calls then that first summe,r and they UPGRADE to a larger outside unit, they will have installed the correct coils inside. |

Thanks... I've been digging at it with a screwdriver and socket set trying to figure out how to get to the underside of the coils. They are really caked. There's a triangular piece of metal there... It seems like if I can get it off, I can clean the coils. The distributor coupling is in the way though, and I'm pretty sure... no, really sure,... that I don't want to disconnect it.  I'm gonna keep trying to wiggle it out somehow and I'll keep checking in here in case someone has some more ideas. |

the coils wont just come out,,unless you cut the lines,, YOU dont WANNA do that lol.....idtell ya how to take it out,,but i have yet towork on that kinda unit,, but to me they all look the same,, a few bolts here and there,,, if not you may need to hire someone, DONTuse an acid to clean it,,, go get some non acid stuff ,, we use some stuff made by "'ace"' not the hardware store,,butt he brand,,its an alkinine, foaming cleaner,, and use a brush and hose to clean them also,,but carefull dont bend the fins,,, sorry to lazy to let the new spell check work! |
Same thing happened to me, see this thread I started today also http://www.ar15.com/forums/topic.html?b=1&f=5&t=350606 Good luck, Lord knows I need it |

Update: I was able to get the plate off of the front of the coils, so I could get my shopvac hose in there with a brush attachment. I was able to get about 95% of the scum off of the coils. It's got to be a lot better than it was... it was like a layer of felt over the coils. I was able to get it pretty clean without much damage to the fins. I am not sure if I'm going to use a solvent or not. The hardware stores are closed, and they look pretty clean. Any household solvents I could mix up tonight to put a finishing touch on this thing? |
