5 Sounds You Don’t Want Your Cape Coral, FL Ductless System to Make

June 28, 2024

Ductless systems come designed to work quietly, so something could be wrong whenever you hear unusual sounds from your system in Cape Coral, FL. Below, we will discuss some ductless noises you shouldn’t hear and what they mean.

1. Banging

As your system advances in age, its components wear out. These worn-out components may become loose and collide with other moving parts, causing a banging noise. Also, you may hear a banging noise when debris falls into the system’s outdoor unit and collides with the rotating fan blades.

2. Whistling

After the refrigerant absorbs heat at the indoor coil during summer, it passes through the compressor, which increases its pressure and temperature. If the refrigerant lines have any damage, the fluid may escape and make a whistling sound.

You may also hear this noise when your air filter is too dirty. This sound occurs as the system draws air through the tiny openings left on a dirty filter. Clean or replace your filter regularly to alleviate airflow issues.

3. Bubbling

A bubbling or gurgling sound indicates holes in the refrigerant lines. The openings allow air to enter and mix with the refrigerant, causing the noise.

4. Rattling

If the screws holding the outdoor unit’s cover panel in place loosen, the cover panel may produce a rattling noise as the system runs. A rattling sound can also occur when your system has loose components.

5. Buzzing

A buzzing noise may be a sign of electrical problems. Always leave electrical repairs to a licensed technician rather than attempting DIY repairs, as the components can harm you.

Allowing abnormal noises to continue for extended periods can potentially cause more damage to your ductless system. Call our experts at Spectrum Air Conditioning and Refrigeration to schedule ductless AC repairs in Cape Coral, FL.
