Hey i just now noticed a bubbling type of sound coming from the ac unit,
its a 2001 honda accord ex with the climate control, it stops and then starts up again its annoying to say the least lol, anyone know of this problem

 

Check that water drains from the evaporator drain line when AC is engaged. Low humidity can sometimes make this difficult; too little moisture to cause a drain. Hadrly ever have that problem in Houston. If no water draining, you may be accumulating enough water to hear the water sloshing around inside the evaporator housing.

I've also heard some hissing/gushing sounds from evaporator when charges begins to get low. When compressor cycles off the system equalizes pressure across expansion valve and noise is generated.

good luck

 

are you sure the noise is coming from the a/c compressor? have you checked your radiator overflow tank/coolant level lately to make sure that it has nothing to do with that?

 

is it during operation or afterwards when you turn it off? if it is afterwards it's normal as the pressure equalises the in system.....my home ac unit does that all the time

 

thanks for the quick reply, it makes the noise during operation, kind of like a
gurgiling of some type if that makes sense, at first it did it every once in awhile but it has picked up

 

we had same kind of issue in a few earlier cars 94-95 ,while under warranty , what we did was to evac the a/c system and keep it under vacc for 3-5 hours then recharge it ,, that tip came straight from honda tech line ..
it might be a waste of money and time but you might want to give that a shot ,, without any of us hearing the actual noise it is kind of hard to diagnose properly
