Why Is the Ductless System in My Columbia, SC, Home So Loud?

Ductless mini-split systems have lower operating costs than many other heating and cooling equipment types. Thus, having one in your Columbia, SC, home could leave you with lower energy bills and a smaller carbon footprint. However, a ductless mini-split system isn’t impervious to problems. The development of loud, jarring noises is one of the first signs of issues.

Rattling

Time and the constant movement of air could cause mounted components to come loose. If you hear rattling or clanging sounds coming from your ductless mini-split’s outdoor condenser, tightening loose bolts could solve the problem. During a routine maintenance service, we check for loose and worn parts and replace or tighten them as needed.

Hissing

Hissing sounds at your mini-split’s outdoor condenser may indicate a refrigerant leak. As air bubbles form along refrigerant lines, you’ll hear hissing or bubbling noises nearby.

Refrigerant leaks force ductless mini-split systems to work harder. If you ignore them, they could lead to compressor failure or collapse.

Buzzing

Mini-splits are hard-wired into residential electrical systems. If there’s a short along your mini-split’s connections or other electrical issues, you may hear a faint but persistent buzzing sound.

Ongoing electrical problems can also fill the area with the faint scent of burning wires and thin, whitish smoke. Rather than attempting to troubleshoot them yourself, turn your ductless mini-split system off and schedule repair services. Otherwise, you risk further damage and a costlier ductless HVAC system repair.

Skipping routine ductless mini-split system maintenance increases the likelihood of issues and shortens equipment lifespan. From loose components to odor-causing biological growths, we can help you avoid many common performance-related problems.
