Should My Ductless System in Viera, FL, Make So Much Noise?

Ductless systems are incredibly popular. That’s in large part to their energy efficiency and the amount of control they give Viera, FL, homeowners over their heating and cooling. These systems should run in near silence, though. Learn what’s happening with your ductless system if it’s making a lot of noise.

Buzzing Sounds

Buzzing sounds can point to a variety of problems, some more worrisome than others. For instance, if there’s a loose component on the outside of your ductless mini-split, it may buzz while the system runs. However, buzzing can also point to electrical problems that make your ductless system inefficient and less effective.

Rattling Sounds

Much like buzzing sounds, a rattling noise coming from your ductless mini-split may not point to anything major. If a panel on the outside of the system comes loose, it’ll rattle. However, rattling sounds that persist when all panels are tightly in place point to other issues.

The most common cause of these rattling noises is a loose internal component. When you notice one of these, you need to ask a professional HVAC service technician to diagnose and repair the issue.

Hissing Sounds

Your ductless mini-split relies on refrigerant to heat and cool your home. This refrigerant runs through the system through narrow tubes that help with heat transfer and keep your home at the temperature you set on the thermostat.

If a small hole forms in one of these lines, you’ll have a refrigerant leak. These holes also create a hissing sound that you’ll hear any time the system runs. Not only is it unsafe for you to attempt refrigerant line repairs on your own, but it’s illegal for unlicensed individuals to handle refrigerant.
