Why Does My Ductless Heater Make So Much Noise?

Low humming is usually a normal sound for ductless heaters. Sometimes, they also swoosh. If you hear your ductless heater making another noise, it could signal trouble. Here are the possible causes of the noise you’re hearing from your ductless heater in your Taylorville, IL, home:

Rattling

A rattling sound indicates that something has come loose somewhere inside your ductless HVAC system. Generally, this will likely happen in the outdoor portion of the ductless mini-split. In some cases, it means that something has fallen into the ductless HVAC system, such as debris or even small pebbles that the wind kicked up.

Buzzing

Buzzing sounds can indicate that the ductless HVAC system is drawing too much power for some reason, which can lead to overheating or a tripped breaker. Electrical power overages of this kind are solely a job for a professional service technician.

Whistling

Most of the time, you’ll hear this noise if there’s a refrigerant leak. Your ductless HVAC system won’t work efficiently if it’s losing refrigerant. Because the system loses pressure when this happens, it could damage the compressor because of overworking.

It’s prudent to shut off your ductless HVAC system if you hear any of these noises to prevent further damage If you’re not sure about a noise you hear, it’s wise to err on the side of caution and engage the help of a professional service technician. Never attempt to repair a refrigerant leak on your own; it’s a dangerous substance that can harm your health.
