Why Is My Ductless Heating System So Loud in Rocklin, CA?

It’s common to hear those who sing the praises of ductless HVAC systems in Rocklin, CA, talk about their ability to perform their work in nearly total silence. Therefore, you should treat any loud noises suddenly emerging from your system as major causes for alarm. Let us tell you about a few noises that might come from your ductless mini-split heating system and what they usually mean.

Rattling

A few different things may explain any rattling noises that coming from your mini-split system. For the outdoor unit, it’s possible that some debris, like a collection of twigs or pebbles, has found its way into the system and begun tumbling around and possibly damaging important components. For the indoor or outdoor unit, a bolt, screw or other little part may have come loose, moved out of its proper place and begun shaking around.

Whatever the reason for this sound, the way to most effectively get rid of it is the same: schedule repair or maintenance services. During a periodic tune-up, trained HVAC service technicians can inspect your system, fasten loose parts and remove any troublesome debris. In the process, they can improve the system’s performance and detect latent problems before they become too serious.

Hissing or Gurgling

Ductless mini-split systems use refrigerant to transfer heat from one area to another, and this substance usually occupies a gaseous state. If any holes emerge in the copper refrigerant lines, you’ll probably start to hear hissing as it escapes. You may also hear bubbling or gurgling once air moves in, displaces the gas and forms bubbles.

Refrigerant is toxic and can endanger your health. Leave the job of handling it, replacing it and stopping leaks to our professionals.

Grinding

Your mini-split system may emit a quiet hum as it operates. While that’s normal, loud grinding sounds are not. These noises usually indicate the presence of some serious mechanical issue, like a malfunctioning blower motor.

You can always trust your ears to alert you to serious HVAC-related problems. As soon as you hear that something is amiss, call Jaguar Heating & Air and let us provide you with professional ductless heating and AC services in Rocklin, CA.
