Also referred to as mini-splits, ductless HVAC systems provide quiet performance and excellent energy efficiency. However, these systems can sometimes produce unusual sounds. Read on to understand the meaning behind these four noises and how they might affect the comfort of your Allison Park, PA home.

1. Hissing Sound

A hissing sound often indicates a refrigerant leak within your ductless system. The refrigerant absorbs and releases heat, allowing the system to cool or heat your home. When there’s a leak, not only can your unit lose its efficiency, but it can also lead to compressor damage if left unchecked.

Additionally, refrigerant leaks are harmful to the environment. Therefore, it’s essential to address this sound promptly by contacting a professional.

2. Rattling Noise

If you hear a rattling noise from your ductless system, it might be due to loose components. Over time, screws, bolts or other parts can become loose due to the system’s regular operations or external factors. While this might seem minor, neglecting it can lead to more significant problems, such as components wearing out prematurely.

3. Buzzing Noise

A buzzing noise from your HVAC system often points to problems within its electrical system. This could be due to faulty wiring, a malfunctioning capacitor or other electrical components acting up.

It’s essential not to ignore this noise, as electrical issues can be a potential fire hazard or cause further damage to your system. Scheduling regular AC maintenance can help in the early detection and rectification of such issues, helping ensure your system’s longevity.

4. Vibration

If your outdoor unit emits a vibrating noise, it’s likely that it isn’t sitting level. Addressing this issue promptly ensures your unit performs efficiently and prevents undue wear and tear on its parts. We recommend engaging a professional to inspect and, if necessary, readjust the unit’s positioning.
