Why Your Mini Split Makes Noise When Turned Off

Your mini split air conditioner or heat pump makes some noise even when it's turned off for a few reasons:

Condensation Drainage

• The unit produces condensation which needs to drain properly. You'll hear the sound of water trickling or dripping as it drains from the unit. This is normal and ensures humidity levels in your space are balanced.

Fan Operation

• The indoor unit fan may run for a short time after the unit is turned off to dissipate any remaining cool air during cooling mode or hot air during heating mode. This helps avoid temperature fluctuations in the room. The fan will stop once the temperature equalizes.

Defrost Mode

• If you've been running the heating mode, the outdoor unit needs to defrost from time to time. It will temporarily switch into defrost mode, where you'll hear gurgling sounds as the refrigerant flows in reverse. The fan will also run during this process. Defrost mode usually only lasts 10-15 minutes to melt away any ice buildup.

Electrical Components

• You may hear a faint clicking, buzzing, or whirring coming from the unit. This is the normal operation of electrical components like capacitors, relays, and thermostats as they maintain power or click on and off.

Common Causes of Mini Split Noise When Off

If your mini-split is making noise even when it's turned off, something's not right. Here are some common culprits to check:

Faulty Parts

• Unfortunately, components like fans, valves, or compressors can malfunction, causing annoying sounds. The good news is, that many are affordable and easy to replace. Call a pro to diagnose and replace the faulty part.

Refrigerant Issues

• The refrigerant flowing through your unit could be low or leaking, making the compressor work harder. An HVAC tech can recharge the refrigerant, and check for and seal any leaks.

Drainage Problems

• If you hear gurgling or dripping sounds, the drain line is probably clogged. Try pouring a mixture of water and vinegar down the drain to clear it. If that doesn't work, call for service. A clogged drain can damage your unit if left unfixed.

Vibration

• Loud vibrations or rattling noises often mean your outdoor unit isn't level or is making contact with another surface. Have a pro-re-level the unit to stop the vibrations and prevent damage.

By troubleshooting these common issues, you'll get your mini split whisper-quiet again in no time. But always call a licensed HVAC technician for any repair or recharge needs. They have the proper tools, training, and refrigerants to get your unit humming happily and safely again.

How to Troubleshoot and Fix a Noisy Mini Split

If your mini-split is making noises when it's turned off, a few issues could be the culprit. Try these troubleshooting steps to diagnose and fix the problem:

Check the Fan

• The fan inside the mini-split unit could be the source of the noise. Even when the unit is off, the fan may continue to spin for a short time. This is normal and the noise should stop once the fan turns off completely. However, if the fan seems stuck on or is making grinding or squealing sounds, it likely needs repair or replacement. Call an HVAC technician to inspect the fan.

Inspect the Compressor

• The compressor, which pumps refrigerant through the system, can also cause noises when it's malfunctioning. Strange clicking, buzzing, or rattling sounds coming from the compressor usually indicate it needs service. A technician can test the compressor to determine if repairs or a replacement are needed. Leaving a failing compressor unchecked can lead to more serious issues, so it's best to have it inspected as soon as possible. 

Check for Obstructions

• Another possibility is that debris has made its way into the unit, blocking airflow or the movement of parts. Leaves, dirt, small animals, and nesting materials are common culprits. Shut off power to the mini split and use a flashlight to peer inside the unit. Gently remove any obstructions you find. If the problem continues after clearing out debris and the unit seems to be operating normally, it's best to schedule a service call. A technician can fully inspect the unit to pinpoint the exact cause of the noise and perform necessary repairs to get your mini-split running quietly again.
