Why is my AC getting a louder humming sound?« Back to Previous Page

Well, i've encountered similar scenarios in the dubai region where AC units started making louder humming sounds over time. This issue often points towards a few potential causes that you might want to investigate.

Firstly, it could be a sign of worn or damaged components within the ac unit itself. In the uae, we experience high temperatures and humidity levels which can cause wear on parts like fan blades, compressor, or even the electrical connections. If these start to degrade, they can indeed produce unusual noises that increase with usage.

Another common culprit could be an improperly installed or clogged air filter. When filters are dirty or obstructed, it forces the ac unit to work harder which can lead to increased vibration and noise levels. In dubai, where dust and sand particles are a concern due to our environment, regular cleaning of the air filter becomes crucial.

Additionally, loose connections in the wiring can also cause humming sounds especially if they're not securely fastened. This is something that even your landlord's inspection might have missed as it requires a more thorough electrical check-up than just visual inspection.

A less common but still plausible scenario could be a refrigerant leak. Although rare, this would typically present with other symptoms like reduced cooling performance or the ac blowing warm air. However, if there’s a gradual loss of pressure over time, it might manifest as a louder noise.

Given that you're experiencing an increase in the humming sound and it's becoming more noticeable especially during higher usage times, i strongly recommend getting a professional inspection done. In dubai, we have specific regulations regarding indoor air quality which your ac unit must comply with to ensure comfort and safety for residents. A certified technician can pinpoint exactly what’s causing the noise and provide a solution.
