Air conditioners are complicated systems that rely on many different parts, which includes a compressor, evaporator coil, condenser coil and refrigerant to regulate your home’s temperature and humidity level. While these machines are generally robust and reliable, it’s not unheard of for AC units to make strange sounds, which may indicate that something is amiss. One of these sounds is dripping, gurgling, bubbling or running water. These worrying noises can be attributed to several causes.
This is a common air conditioner sound you may hear on hot, humid days and is no cause for alarm. Simple condensation buildup is probably the cause of the sound. As your air conditioner performs, moisture from the inside air gathers on the evaporator coil and drips into the drain pan beneath. This pan is designed to catch and direct the condensed water away from your home via a drain line.
Then again, if the drain becomes blocked or compromised, water can accumulate in the pan, producing a dripping or splashing noise as freshly collected condensate drips into the pool down below. If the dripping noise becomes a nuisance, locate the drain pan under the indoor portion of your air conditioner and clear it.
Also, take AC dripping sounds as a warning sign that the condensate drain line is blocked and must be cleared. A float switch ought to automatically shut off your conditioner before the drain pan overflows and creates water damage, but the float switch could always not work properly. Plus, if your AC keeps turning itself off because of a full drain pan, you’ll need to fix the problem before your unit will operate normally again.
While air conditioners produce condensate during the cooling process, they do not run on or consume water. This simply means your AC should not ever sound like running water. If you hear this sound, it could mean the evaporator coil has frozen over and is now thawing and dripping water onto the ground.
This can happen for a few reasons, including:
Refrigerant is a critical ingredient in the cooling process. If a leak has developed or air comes to be trapped in the refrigerant line, you may hear gurgling or bubbling as the refrigerant flows. Along those same lines, your system could possibly gurgle due to overcharged refrigerant. Always leave AC repair work to a professional who can verify the proper refrigerant charge.
A hissing noise from your air conditioner could be the result of one of these issues:
