Is AC causing cough and strange noises?« Back to Previous Page

The AC in my apartment seems to be running extra hard lately, especially at night. It’s making a strange humming noise that’s keeping me up, but more concerning is the persistent dry cough I’ve been having since we moved into this new unit last summer. Could the air quality or the way the AC is working be causing these issues?

Absolutely, the AC unit could be contributing to both your cough and the strange humming noise. In Dubai/UAE, where humidity can vary significantly, the air conditioning system plays a crucial role in maintaining indoor environmental quality. It's not uncommon for older or improperly maintained units to cause issues like those you're experiencing.

The persistent dry cough might be linked to factors such as poor air filtration, which could lead to allergens and irritants lingering in the air. In the UAE, we often deal with high levels of dust, pollen, and even mold spores, especially during certain seasons. If your AC is not properly servicing these particles, it can certainly impact your respiratory health.

Regarding the humming noise you're hearing at night, this could be a sign that the unit isn't running efficiently or maybe there's an issue with its components like the compressor or fan. This sound can also indicate that the air flow is restricted due to blockages in filters or ducts, leading to extra strain on the AC system.

It's crucial to have your AC inspected by a professional service provider who understands the local conditions and regulations. In Dubai, you should check if the company adheres to the Building Control Regulation No. 2 of 2018, which governs air quality standards in buildings. An expert can diagnose any issues and recommend necessary repairs or replacements.

Call 800-MOLDS or email hello@saniservice.com for a professional assessment. Regular maintenance is key to ensuring your AC operates efficiently and doesn’t affect the indoor air quality adversely. Keeping up with seasonal cleaning of filters, checking refrigerant levels, and having a thorough inspection can greatly reduce the likelihood of such issues.

Taking these steps will not only address your immediate concerns but also help in preventing future problems that could impact both comfort and health. Remember, the air you breathe indoors matters, especially in a climate like Dubai's where environmental conditions can change drastically.
