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 wrong. 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 could hear on hot, humid days and is no cause for alarm. Simple condensation buildup is probably to blame. As your air conditioner performs, moisture from the indoor air collects on the evaporator coil and drips into the drain pan beneath. This pan was created to catch and funnel the condensed water a safe distance away from your home via a drain line.
However, if the drain becomes clogged or damaged, water can accumulate in the pan, producing a dripping or splashing noise as freshly collected condensate drips into the pool below. If the dripping noise becomes an annoyance, 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 creates 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 be forced to fix the problem before your unit will run normally again.
While air conditioners produce 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 noise, it could indicate 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 crucial 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. Additionally, your system may gurgle due to overcharged refrigerant. Always leave AC service work to a professional who can verify the proper refrigerant charge.
A hissing noise from your air conditioner could indicate one of these problems:
