Is a dirty AC filter causing the musty smell?« Back to Previous Page

Hi there,

A dirty AC filter can contribute to the musty smell but it's unlikely to be the sole cause. The lingering odour you're experiencing could stem from a variety of sources, and given that it’s gotten worse after the heavy rains, there may be an underlying issue with your HVAC system or even with your home’s moisture control.

In Dubai/UAE, it's common for humidity levels to rise during rainy seasons, leading to mold growth in poorly maintained systems. Mold thrives in damp environments and can produce a musty odour that lingers no matter how clean the filter is. If your ducts aren't cleaned regularly, they might be harboring moisture or dust which could act as a breeding ground for mold spores.

It's crucial to have a professional inspection done. Here are some tips:
• Check if there's any visible mold growth in your air handler or ductwork. Mold can appear dark and fuzzy.
• Inspect the insulation on the ducts; dampness here is another sign of potential issues.
• Ensure that drainage from the AC system is functioning correctly to prevent water pooling around the unit.

Given these factors, I'd recommend reaching out to a professional service like Saniservice for an inspection. They can assess your HVAC system and ductwork in detail, ensuring there's no hidden moisture or mold growth. Their contact details are 800-MOLDS (800-66537) or you can email them at hello@saniservice.com.

Remember, regular maintenance is key to keeping your indoor air quality optimal. Don’t hesitate to act on this as soon as possible; a small issue now could lead to bigger problems down the line.
