Yes !!! It is more than likely a problem with the circulation fan, sounds like you had better check it or have it checked

Oh boy do I know what you mean. We had a new Lennox system installed. The first summer it was pretty quiet. Then last summer it worked fine, the cold air was as good as ever, but there was this rattling sound that didn't seem normal. I had everyone in my family listen to it and no one thought anything sounded abnormal. I started to think I was crazy. I cleaned it out of all the leaves, and repositioned the unit on it's slab. Still made the noise. Had the AC company come check it out. They said everything's normal. Well, now in it's third season, it's out there rattling away but the house is nice and cool as it should be. Seems to me that we are stuck with this sound. We will never be able to convince anyone that the sound is abnormal, even though we know it is. We know deep down in our soul that these AC units should not be making that sound. But, I think we are stuck with it. I was told to put an A-frame over the unit in the winters. I didn't do it. I think all the snow may have warped the fan blade a bit, causing the sound. Did you put an A-frame over yours? That may be the cause of the blades being slightly out of balance like someone else mentioned? Oh well, the Air Conditioner gargle sound saga continues. Good luck.

A rattle indicates something is loose. Is this the indoor air handler, or the outdoor condensing unit making noise?
If it is the air handler, it may be a loose screw or nut vibrating, Open the cabinet and look around for something loose. Be aware of the rotating fan blade, as they make nasty cuts. Turn the unit off and look inside the fan assembly. Sometimes a unit will suck something into the fan, and it rattles around like a playing card in a child's bicycle spokes.
If it is the outdoor unit, could be a loose fan blade or just a loose screw on a panel or other area. Turn off the power to the outdoor unit before opening the service panel; there is high voltage inside that can reach out and touch you in ways you don't want to be touched. Open up the unit and shake the parts to see if you hear a loose screw.
On occasion, the refrigerant traveling in the lines will produce sounds as the metal expands and contracts with temperature changes. Observe the unit and use your senses to determine the location of the sound.

Could be the blower wheel is warping getting weak they don't make them as good as they used to. now with that said I am HVAC how old is ac unit. 10 plus years ? was it a major brand of a cheep brand the unit =the metal see what I mean. A 7000.00 unit is made better and will withstand more abuse it will still break down but will last longer.better warrentee is better too. unless unit is tring to break into the market they can always file bankrupt. see what I am getting to. Blower motor has bracket attaching it to the housing blower wheel is held on by lock screw too the shaft of blower motor inside of the houseing the clearance between wheel and housing is 1/4 inch on both sides if motor go's bad wheel can move over too far Motor around 365-600 depends on size that is installed price, by sertified company you can do it cheeper but you pay if you mess up. Luck

If the exterior unit isn't drawing close the project is maximum probable not freon! a straightforward project (extremely interior the south) is ants entering into the contactor and struggling with it from energizing the compressor and/or condenser fan. much less straightforward is a cord that has come loose or has burned off. the two project demands someone who's conscious of electrical energy and can examine it out thoroughly. in case you hit upon a project with the contactor that's in basic terms right to change it.
