Air conditioners are complex systems that rely on various components, including a compressor, evaporator coil, condenser coil and refrigerant to regulate your home’s temperature and humidity level. While these machines are typically robust and reliable, it’s not uncommon for AC units to make strange sounds, which may indicate that something is awry. One such sound is dripping, gurgling, bubbling or running water. These distressing noises can be attributed to several causes.
This is an often reported air conditioner sound you might hear on hot, humid days and is no reason for alarm. Simple condensation buildup is most likely to blame. As your air conditioner performs, moisture from the inside air collects on the evaporator coil and drips into the drain pan underneath. This pan was created to catch and direct the condensed water away from your home via a drain line.
However, if the drain becomes blocked or damaged, water can accumulate in the pan, leading to 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 remove the water.
Also, take AC dripping sounds as a warning sign that the condensate drain line is clogged and needs to be cleared. A float switch should automatically shut off your conditioner before the drain pan overflows and causes water damage, but the float switch could always break. Plus, if your AC keeps turning itself off because of a full drain pan, you’ll have to correct the drain pan issue before your unit will operate normally again.
While air conditioners create condensate as a part of the cooling process, they do not run on or utilize water. This means your AC should never sound like running water. If you hear this sound, it could be because 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 crucial ingredient in the cooling process. If a leak has developed or air gets trapped in the refrigerant line, you may 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 ensure the correct refrigerant charge.
A hissing noise from your air conditioner could indicate one of these problems:
