Air conditioners are complex systems that rely on various parts, which includes a compressor, evaporator coil, condenser coil and refrigerant to regulate your home’s temperature and humidity level. While these machines are typically strong and reliable, it’s not unusual for AC units to make strange sounds, which may indicate that something is wrong. One of these sounds is dripping, gurgling, bubbling or running water. These worrying noises can be traced back to several causes.
This is an often reported air conditioner sound you might hear on hot, humid days and is no reason you should be alarmed. Simple condensation buildup is most likely the culprit. As your air conditioner performs, moisture from the inside air collects on the evaporator coil and drips into the drain pan beneath it. This pan is designed to catch and move the condensed water clear of your home via a drain line.
Then again, if the drain becomes clogged or compromised, water can accumulate in the pan, leading to a dripping or splashing noise as freshly collected condensate drips into the pool underneath. If the dripping noise becomes too irritating, find the drain pan under the indoor portion of your air conditioner and remove the water.
Also, take AC dripping sounds as a signal that the condensate drain line is blocked and should be cleared. A float switch is supposed 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 be forced to fix the issue before your unit will run normally again.
While air conditioners produce condensate during the cooling process, they do not run on or use water. What this means is your AC shouldn’t sound like running water. If you hear this sound, it might 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 ingredient in the cooling process. If a leak has developed or air gets caught in the refrigerant line, you might hear gurgling or bubbling as the refrigerant flows. Similarly, your system may gurgle because of overcharged refrigerant. Always leave AC repair work to a professional who can make sure the proper refrigerant charge.
A hissing noise from your air conditioner could signify one of these problems:
