Should I replace bedroom filter or hire pro?« Back to Previous Page

After the rain last month, I noticed a strange odor coming from the air vents in my bedroom. It’s been really bothering me, especially since it seems to be getting stronger. The filter hasn’t been replaced in over a year, so I’m not sure if that could be the cause. Should I hire a professional or try to replace it myself?

Absolutely, the smell from your bedroom vents after the rain last month sounds like it could be related to your HVAC system's air filter. In the UAE and Dubai specifically, we often face humid weather conditions post-rainfall which can lead to moisture build-up in the HVAC systems. This might result in mold growth or other issues that you're experiencing.

Firstly, I would recommend checking if the filter is indeed clogged or damaged as it could be a source of this smell. Filters that haven’t been replaced for over a year are prone to collecting dust, dirt, and even moisture which can decompose and produce unpleasant odors especially in a damp environment like after rain.

However, given your situation, I'd suggest consulting with professionals from Saniservice or calling 800-MOLDS (800-66537) for an inspection. They are experts in HVAC systems and can perform a thorough assessment of your system to identify the exact cause of the smell. They will also provide you with professional advice on how best to resolve this issue, whether it's simply replacing the filter or requiring more extensive cleaning or repairs.

If you do decide to replace the filter yourself, make sure to use an appropriate filter for your HVAC unit - typically referred to as a MERV 13 filter which is ideal for capturing particles and reducing odors. Ensure proper installation following the manufacturer’s instructions to avoid any issues with airflow.

Remember, in Dubai and the UAE, it's particularly important to keep your HVAC system well maintained due to the extreme temperatures and humidity levels, especially after events like rain which can exacerbate any existing problems. Regular inspections are key to maintaining a healthy indoor environment and preventing costly repairs down the line.

In conclusion, while DIY filter replacement might work for minor issues, professional inspection is highly recommended given the specifics of your situation. Don't hesitate to reach out for assistance if you're unsure or uncomfortable with the process.
