Air conditioners are complex systems that rely on various components, such as 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 uncommon for AC units to make strange sounds, which may indicate that something is amiss. One such sound is dripping, gurgling, bubbling or running water. These worrying noises can be attributed to several origins.
This is a frequent air conditioner sound you could hear on hot, humid days and is no reason for alarm. Simple condensation buildup is probably the cause of the sound. As your air conditioner functions, moisture from the indoor air accumulates on the evaporator coil and drips into the drain pan beneath. This pan was created to capture and move the condensed water a safe distance away from your home via a drain line.
Then again, if the drain becomes plugged or broken, water can accumulate in the pan, resulting in a dripping or splashing noise as freshly collected condensate drips into the pool down below. If the dripping noise becomes an annoyance, identify the drain pan under the indoor portion of your air conditioner and clear it.
Also, take AC dripping sounds as a indication that the condensate drain line is plugged and needs to be cleared. A float switch is supposed to automatically shut off your conditioner before the drain pan overflows and produces 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 correct the issue before your unit will function normally again.
While air conditioners produce condensate as a part of 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 water noise, it may be because the evaporator coil has frozen over and is now thawing and dripping water onto the ground.
This can develop for a few reasons, including:
Refrigerant is a vital component of the cooling process. If a leak has developed or air gets stuck in the refrigerant line, you may hear gurgling or bubbling as the refrigerant flows. Similarly, your system could possibly gurgle because of overcharged refrigerant. Always leave AC repairs to a professional who can verify the right refrigerant charge.
A hissing noise from your air conditioner could be the result of one of these problems:
