Several factors can result in a noisy ductless mini-split in your Northshore, LA home. Some sounds are normal and part of the operation. However, mechanical problems and malfunctions can lead to very loud noises that are out of the ordinary.
Sound of Expansion and Contraction
If the housing of your ductless mini-split unit experiences expansion and contraction because of changes in temperature, this can cause loud sounds. You may notice a loud pop or cracking noise as minor movement occurs. These sounds are usually harmless if you don’t notice them frequently and there’s no damage to your HVAC system.
Debris-Caused Rattling Noises
If any debris accumulates on the interior of your ductless system, this can cause a rattling sound to occur when your equipment runs. This is common in exterior equipment, where grass, leaves, twigs and other debris are present. Routine maintenance and inspections can keep your system clear.
Gurgling Sounds From Moisture
Ductless mini-splits often run a defrost cycle to prevent any interior components from freezing up during the air conditioning process. When this cycle runs, it can result in gurgling or clanking sounds from ice melting and breaking apart. This process is normal but shouldn’t result in any moisture pooling near the system or leaking out of it.
Electrical Malfunctions and Abnormal Sounds
If your mini-split is experiencing electrical problems, this can result in buzzing or humming sounds. You may also hear crackling inside your system when it is starting up or running. Turn it off immediately, and call for assistance if you suspect an electrical malfunction.
Abnormal ductless mini-split sounds can come on without warning or increase over time. Scheduling a routine inspection and maintenance for your system can ensure everything is working correctly and as quietly as possible.
