When trouble strikes your ductless AC system in Richboro, PA, you’ll probably hear it happening. However, it isn’t always simple to understand what causes each of the noises you hear. Keep reading to learn about three of the most common ductless HVAC noises and what they mean.
1. Hissing or Bubbling
If you hear hissing from your ductless AC, it probably means that refrigerant has leaked out of the system through a hole in its refrigerant lines. Bubbling noises mean that air bubbles have formed within the lines where the refrigerant used to be.
Refrigerant is quite toxic, and you should not attempt to refill your system with it on your own under any circumstances. Instead, evacuate your home as soon as you notice signs of the leak and ask HVAC technicians to take care of the issue.
2. Rattling
If there are rattling sounds coming from your ductless AC, it’s likely that either there’s debris in your system, or one or more components have become loose. The appropriate solution for both of these problems is to schedule professional maintenance or repair service.
3. Grinding
Each air handler unit in a ductless AC needs a set of oiled bearings to function. Over time, however, these bearings may lose their lubrication, causing the parts of the air handler to grind up against one another.
This noise can be especially jarring. Without prompt action, the friction on the bearings may cause significant damage to the air handler.
We strongly advise you to listen closely for any odd noises from your ductless AC. Your proactive response to such things can mean the difference between staying cool or sweating through the summer.
