3 Causes for Strange Noises in Your Ductless AC System

Ductless air conditioners allow you to avoid all of the trouble of bulky ducts. But like any mechanical system, they can experience trouble, especially without proper maintenance. Since ductless AC systems should operate quietly, strange noises almost always point to trouble. Here are three odd noises that the ductless AC system in your home in Peoria, AZ, might make and their likely causes.

Hissing

If you hear hissing or bubbling noises, your ductless AC system is probably leaking refrigerant. The hissing comes from gaseous refrigerant flowing out of holes in your system’s refrigerant lines, and the bubbling occurs because air bubbles have formed in the refrigerant lines after the refrigerant’s outflow. A chlorine-like or ether-like smell in the air should further confirm this suspicion.

Refrigerant is extremely dangerous, and you should evacuate your home and ask trained HVAC service technicians to deal with this problem. Under no circumstances should you attempt to either stop the leak or replace the refrigerant on your own.

Rattling

Two things typically cause rattling sounds to come from your ductless AC system. Either some of the nuts, bolts or screws in one of the system’s parts have come loose, or dust, pebbles and other debris have found their way into the system. When these things happen, the loose parts and the debris may both rattle around as the ductless AC system does its work.

HVAC service technicians can deal with such issues when they administer maintenance on your ductless air conditioner. You should let service technicians clean your system, inspect its parts and perform a tuneup at least once per year.

Grinding

Ductless air conditioners use a series of oiled bearings to enable each of their air handler units to function with as little friction as possible. Over time, however, these bearings will lose lubrication and may therefore start producing grinding noises.
