Does Your AC Sound Like It’s Dripping Water?

As the weather continues to grow hotter each day, you might notice that your HVAC unit is making a dripping noise. This sound, which can plague both residential and commercial air conditioning units, is an indication that at least one element in your unit is not working as it should. Here’s how you can troubleshoot your HVAC unit when you hear a dripping sound.

Condensation Drain

Most commonly, a clogged or worn out condensation drain is what is causing your air conditioning system to make a dripping sound. If the drain is easily accessible, simply clear the clog or replace the drain. Note that different HVAC units have varying ways to deal with water, so it’s important to consult the manual before jumping in. At All Temp, we will gladly ensure that the condensation drain is in working order.

High Water Feed Rate

Water feed rate, or the amount of water that is going into your HVAC unit in order for it to function, can cause water to overflow and spill, causing a dripping sound. In this case, we recommend contacting a professional for repair.

Low Refrigerant

When the refrigerant is low in your air conditioning unit, the pressure in the entire system is lowered. When this happens, the evaporator coil tends to freeze over, and as it melts, water will overflow into the drain pan. Another sign that your unit is low on refrigerant is poor air circulation. 

Drain Pan

As your unit ages, certain parts will wear out. This includes the drain pan, which is susceptible to both damage and rust. A damaged drain pan will be unable to catch water, causing a dripping noise as drops fall through the pan and onto the floor. Fixing a damaged drain pan is as simple as replacing it. 

A properly maintained air conditioning unit should run quietly. If your unit is making any noise, contact All Temp, air conditioning experts located in St. Cloud.
