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 a common air conditioner sound you could hear on hot, humid days and is no cause for alarm. Simple condensation buildup is probably the cause of the sound. As your air conditioner operates, moisture from the indoor air collects on the evaporator coil and drips into the drain pan underneath. This pan is meant to catch and funnel 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, resulting in a dripping or splashing noise as freshly collected condensate drips into the pool underneath. If the dripping noise becomes an annoyance, 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 needs to be cleared. A float switch should automatically shut off your conditioner before the drain pan overflows and produces 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 have to correct the issue before your unit will operate normally again.
While air conditioners make condensate during the cooling process, they do not run on or consume water. What this means is your AC should never 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 happen for a few reasons, including:
Refrigerant is a crucial ingredient in the cooling process. If a leak has developed or air has become trapped in the refrigerant line, you may hear gurgling or bubbling as the refrigerant flows. Along those same lines, your system could very well gurgle due to 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:
