Is dampness from AC causing poor air quality?« Back to Previous Page

After the heavy rains last month, I noticed a persistent dampness in the corner of my bedroom, even though the AC was running full blast. It's concerning because it started to affect the quality of air, and my kids have been complaining of coughs and runny noses. Could this be related to improper ventilation or some other issue with the AC system?

The persistent dampness issue in your bedroom could indeed be linked to improper ventilation or other AC system malfunctions. The UAE has stringent regulations regarding indoor environmental quality (IEQ) and air conditioning systems, especially in the context of preventing mold growth and ensuring healthy living environments.

Firstly, it is crucial to understand that moisture is a breeding ground for microorganisms such as molds, which can significantly impact IAQ. In Dubai, according to the UAE Building Code 2018 (B/C 2018), all buildings must be equipped with adequate ventilation systems that comply with ASHRAE standards to prevent dampness and ensure healthy air quality.

Given your situation where the AC is not effectively addressing the dampness issue, it's highly recommended that you have a professional inspection. This can help identify whether there are issues such as insufficient dehumidification capacity in the AC system or if there are leaks in the ductwork allowing outdoor moisture into the conditioned space.

Moreover, ensure that your HVAC filters are regularly cleaned and replaced to prevent dust and debris from clogging them, which could lead to reduced airflow and increased humidity. Regular maintenance checks by a certified HVAC technician can also address any latent problems within the AC unit or system.

If you suspect mold growth due to moisture accumulation, it's important to act swiftly. Mold spores can cause respiratory issues, particularly in children and individuals with allergies or asthma. The UAE Ministry of Health advises against DIY mold remediation; instead, contact a professional service provider like Saniservice at 800-MOLDS (800-66537) for safe removal.

In addition to AC system optimization, consider enhancing your building's overall ventilation strategy by installing additional exhaust fans in the bathroom and kitchen areas. This can help reduce indoor humidity levels and minimize the risk of mold proliferation.

Lastly, maintaining a relative humidity level below 60% is ideal to prevent moisture-related issues. You may want to invest in a portable dehumidifier for your bedroom until the AC system is properly diagnosed and repaired by an expert.

Remember, the quality of air inside our homes can greatly influence health and comfort. Addressing this issue promptly ensures a safer and healthier living environment for you and your family.
