Air conditioners are complex systems that rely on many different parts, such as 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 unheard of 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 worrisome noises can be traced back 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 most likely to blame. As your air conditioner functions, moisture from the inside air gathers on the evaporator coil and drips into the drain pan beneath it. This pan was created to collect and move the condensed water away from your home via a drain line.
Although, if the drain becomes blocked or compromised, 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, find 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 should 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 fail. Plus, if your AC keeps turning itself off because of a full drain pan, you’ll need to solve the problem before your unit will operate normally again.
While air conditioners produce condensate as a component of the cooling process, they do not run on or utilize water. This means your AC shouldn’t sound like running water. If you hear this water noise, it could mean the evaporator coil has frozen over and is now thawing and dripping water onto the ground.
This can take place for a few reasons, including:
Refrigerant is a vital element of the cooling process. If a leak has formed or air has become caught in the refrigerant line, you might hear gurgling or bubbling as the refrigerant flows. Along those same lines, your system could possibly gurgle due to overcharged refrigerant. Always leave AC repairs to a professional who can ensure the right refrigerant charge.
A hissing noise from your air conditioner could indicate one of these malfunctions:
