Why Does My Ductless AC System Make Loud Noises?

A ductless air conditioner can give you a convenient way to keep your Houston, TX, home comfortable when the temperatures rise. In general, this kind of system should work quietly, but some situations can result in excess noise. If you hear loud noises coming from your ductless AC system, you may need to address any of these problems:

Loose Components

Over time, components like nuts, bolts, or fan blades can loosen and move out of place, resulting in loud vibrations that may disrupt your household. In this case, you can ask a service technician to open up your system, tighten connections and make adjustments to ensure quieter operation.

Electrical Issues

Faulty wiring, a loose connection, or some other sort of electrical problem could result in a noticeable buzzing or humming. You’ll want to address this kind of situation promptly since it could increase the risk of an electrical fire.

Worn-Down Parts

If you hear squealing or whining, you may have to deal with a broken fan motor or belt. Under normal operation, these parts will move smoothly and quietly. If compromised, they can make high-pitched noises and potentially fail at any point.

Refrigerant Leak

Refrigerant exiting out of the system through a small hole can make a hissing or whistling noise. It plays a crucial role in HVAC, allowing heat to transfer from one place to another. With low refrigerant, your system will have trouble keeping your home cool, and the leaking refrigerant could potentially endanger people at your home.

A ductless AC system shouldn’t make too much noise, so reach out for professional assistance if you notice loud sounds coming from your mini-split. If you live in the Houston, TX, area, contact Roberts Air, LLC to set up a ductless HVAC repair appointment right away.
