Is this a wndow unit or central air system? if this is a window unit , your problem is it only needs cleanning (dirt dbber nest-- trash around the back blades-- or the unt is twisted and rubbing the fan shroud. Last but not least, the slinger ring around the back blades (a ring around the end of the blades thats picks up water in the bottom of the unit and sling it on the coils to help cool the hot gases....Thank-you Thank you Thank you very much!

I want to fix my split system ac.


You are referring to the air handler portion of AC. One of the fan blades is hitting something. Kill the power to all of ac and air handler and open up the air handler by removing the panel facing you exposing the fan. Manually turn the blade and look for the offender. Bend back into place, put back panel and tape up properly and turn all breakers back on.

Ir maybe just moving the fan motor itself slightly will do the trick. Whatever is easier and works will do.

Very loud when fan is running


This is likely caused by a faulty blower motor bearings, or the fan has something in it or it could possibly have broken. Shut down power to unit, remove cover and inspect the fan shaft, blades, and spin it. it should freely spin. If it hangs up you likely have a bad blower motor.

Unit makes a loud rattling noise when operating


Hello, most likely the fan blade is either loose or cracked at the hub causing the blade to hit the fan shroud. You will either have tighten the fan blade or have to get a replacement.

I have a 25000 ac window unit i purchased new last year 04/2011 it statrted making a loud noise sort of sounds like fan loose or hitting somethong? i turned it off imediately and contacted store...


Pull the innards out (after unplugging it) and look for a broken blade. It is not very difficult to replace but you must make sure not to break any freon lines while swapping out the blade. A critter could also be in there so be careful.

My air conditioner unit outside is making a very loud banging noise. It sounds almost like a small jack hammer. i noticed it this mornin and immediately turned off my system. Any ideas?


Hi!!

Have you taken a look at it???? It sounds to me like the condenser fan blades are bent or something fell in thru the grill that the blades are hitting on. If this is the case, TURN OFF POWER TO UNIT AT BREAKER BOX , remove the screws around the grill or cover
to get to the blades and fix the problem..

Don't forget to rate this post!! Good Luck!!

Makes loud noise while cooling. sounds like fan is hitting something. a/c is 4 years old, in the wall, problem just began July 2009. Lowering fan speed, or energy saver setting do not help.


That's because it probably is.Shut it off.Pull it out.Set it on a table by the outlet or a/c housing.Plug it into the same outlet.Keep fingers away from the blade and visually watch it.

My guess is the fan blade loosened on the shaft and needs to readjusted and tightened.Or the wires need to be moved out of the way of the blade and tie down(not on the fan blade either foo!!!).
