A ductless system in Abbeville, LA, shouldn’t make any sounds. If you’re hearing loud noises coming from the mini-split system, something is definitely amiss. This situation requires that you have a service technician determine what’s causing the noise. For now, we will discuss why your ductless system sounds so noisy.

Is the Ductless System Short-Cycling?

Short-cycling is when the system constantly turns itself off and on without remaining on for a long enough period. When this occurs, the compressor may be the issue, but it could also be a malfunctioning thermostat. It’s important to address this issue right away because your HVAC system may die before its life expectancy expires.

Do You Hear a Hissing Sound?

If the system vibrates or creates a hissing sound, you may have air bubbles in the refrigerant line. When there’s a leak in the refrigerant line, air bubbles appear. If there’s a leak in your system, we must send a service technician to fix it right away because a leak may lead to a severe breakdown.

Do You Hear a Rattling Sound?

Rattling sounds occur because there’s a loose part within your system. The rattling may be coming from the condenser; if this is the case, the condenser may have debris inside. Components within your system become loose with wear and tear, but one of our service technicians can tighten these components for you.

Do You Hear a Grinding Sound?

Your ductless system has air handlers, and these air handlers have oiled bearings. These bearings prevent too much friction from occurring in your system, but they wear down as time goes by. When this happens, friction increases inside the air handler, and you may begin to hear grinding.

If you have been hearing the sounds described above, contact Desormeaux’s Heating & Air Conditioning, Inc so we can repair your ductless system. Our service technicians have knowledge and experience working on ductless systems and can provide maintenance tips as well.
