Air conditioners are complicated systems that rely on several elements, including a compressor, evaporator coil, condenser coil and refrigerant to regulate your home’s temperature and humidity level. While these machines are generally sturdy and reliable, it’s not unheard of 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 linked to several origins.
This is a common air conditioner sound you might 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 inside air collects on the evaporator coil and drips into the drain pan underneath. This pan was created to collect and direct the condensed water a safe distance away from your home via a drain line.
Then again, if the drain becomes blocked or damaged, water can accumulate in the pan, producing a dripping or splashing noise as freshly collected condensate drips into the pool underneath. If the dripping noise becomes a nuisance, locate the drain pan under the indoor portion of your air conditioner and clear it.
Also, take AC dripping sounds as a signal that the condensate drain line is clogged and should be cleared. A float switch ought to automatically shut off your conditioner before the drain pan overflows and causes 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 correct the issue before your unit will operate normally again.
While air conditioners make condensate as a component of the cooling process, they do not run on or use water. This means your AC shouldn’t sound like running water. If you hear this noise, 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 vital ingredient in the cooling process. If a leak forms or air has become trapped in the refrigerant line, you can hear gurgling or bubbling as the refrigerant flows. Additionally, your system may 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 indicate one of these problems:
