Under ordinary circumstances, ductless AC systems operate exceptionally quietly in comparison to their ducted counterparts. Nevertheless, things can occasionally go wrong, leading your system in Pigeon Forge, TN, to produce some strange and troubling noises. Here are three ductless AC system sounds that you absolutely shouldn’t ignore:
Buzzing
Buzzing generally indicates the presence of an electrical or mechanical issue of some kind. If the issue is electrical, your ductless AC system may have an exposed wire, a faulty blower motor or a bad contactor. If you don’t call on professionals to address these problems, your system’s efficiency will decline, saddling you with higher energy bills.
If the issue is mechanical, your system may have dirty condenser coils, loose bolts or fan blades that have fallen out of position. Scheduling AC maintenance is the way to take care of such things.
Grinding
Do you have a multi-zone ductless HVAC system? Each air handler unit relies on the smooth operation of a series of mechanical components. These components require lubrication to work properly. If that lubrication fades, the parts may begin grinding against one another. As a result, they will wear one another down.
Hissing
While there’s usually some wiggle room around precisely what any given AC noise might mean, this is not the case with hissing. This sound always indicates a refrigerant leak. When air bubbles enter your system’s refrigerant lines and displace the refrigerant that has escaped, you may also hear gurgling noises.
Since refrigerant is poisonous and can inflict permanent bodily damage if you inhale enough of it, evacuate your home as soon as you know that there’s a leak. Ask HVAC service technicians to plug the holes in your system’s refrigerant lines and replace the refrigerant you’ve lost.
If you know what to listen for, you can take action to stop air conditioning issues before they worsen. Once you hear trouble looming, call LB Chase Mechanical to request AC repair services in Pigeon Forge, TN.
