Top Reasons for Ductless AC System Noises in Wilmington, NC

November 20, 2023

Ductless cooling systems in Wilmington, NC save time and money due to improved efficiency and the potential for long-term savings. Such systems are relatively easy to maintain, although there are issues requiring professional attention, too. Read on to learn more about the reasons for ductless AC cooling noises.

Rattling

Rattling means something is loose inside your system, often due to age and regular use. Excess debris causes this problem as well. Reach out to a cooling technician to determine what’s causing the rattling you’re hearing in your ductless AC.

Hissing

A refrigerant line leak typically causes hissing or bubbling noises in ductless ACs. Leaks reduce the efficiency of your system and increase energy costs related to it. Have a technician come over to check out your unit and look for leaks.

Buzzing

A buzzing noise from the outdoor part of your system is often caused by electrical issues requiring professional attention. Regular maintenance helps prevent or minimize this issue. Other reasons for buzzing sounds coming from your ductless unit include:

Broken or loose fan blades
Faulty fan motor
Dirty condenser coils

Lack of Maintenance

A system not well-maintained is more likely to make noises or fail altogether. Generally, an AC system needs an inspection by HVAC professionals at least once a year. It’s a good idea to do this before you use your AC again in the spring and summertime.
