Ductless systems are increasingly popular among homeowners because they run quietly. If you have one in your Bethel Park, PA home and hear anything other than a dull hum, you have a problem. Call for help if you hear these five sounds coming from your ductless system.
1. Hissing or Bubbling
If you hear hissing and bubbling while your system runs, you likely have a refrigerant leak. Since this substance is vital for cooling, a leak can reduce system performance and cause system damage. Leaking refrigerant can cause health hazards, so you must get professional help from an HVAC maintenance technician as soon as you hear this sound.
2. Clicking or Tapping
While there’s nothing wrong with hearing a click sound at startup, you should not hear continuous clicking while the system runs. Repeatedly clicking and tapping sounds during operation mean that you probably either have a problem with your control board or electrical components. Ignoring this problem can lead to complete system failure.
3. Banging or Clanking
Banging or clanking sounds mean that there can be loose components in either the indoor or outdoor unit. This could be something as simple as a loose fan blade or something more serious. Either way, continuing to run the unit can cause further damage.
4. Buzzing or Vibrating
Electrical issues or a failing capacitor often cause buzzing sounds. Continuing to run your system in this condition can damage it and even potentially cause electrical fires in extreme cases.
5. Squealing or Screeching
High-pitched squeals or screeches are not normal and usually point to a motor or fan issue. If you don’t address these problems quickly, these components can overheat or seize up.
If you hear any of these sounds at all, don’t wait to call for help. Catching the issue early can save you money and prevent a major breakdown. Contact Denillo Heating & Cooling for ductless mini-split system repair services straight away.
