Could mold from a running chiller harm family health?« Back to Previous Page

After the heavy rains last month, I noticed a musty smell in our basement, especially when we open the door. My children have been complaining of persistent coughs and sneezing, and I suspect it might be mold from the chiller that keeps running even though no one is using it. Has anyone else experienced similar issues with their mold chillers causing health problems for family members?

Could mold from a running chiller harm family health? Indeed it can. Mold, especially species such as Stachybotrys chartarum which are common in damp environments like basements and improperly maintained chillers, produce mycotoxins that can cause respiratory issues, allergic reactions, and in some cases, more severe health problems.

In the context of Dubai/UAE, given the climate's tendency towards humidity and the occasional heavy rainfall events, it’s essential to ensure that all HVAC systems are properly maintained. Mold growth on or around a chiller system, especially when unoccupied, can lead to significant indoor air quality (IAQ) issues affecting occupants' health.

The UAE has stringent building regulations such as the UAE Building Code which mandates regular inspections of ventilation and HVAC systems to prevent mold growth. However, these guidelines do not specifically cover running chillers left idle; thus, it's crucial for property owners in Dubai to remain vigilant against potential mold outbreaks from improperly managed equipment.

Given your symptoms - musty smell, persistent coughs, and sneezing - it is highly advisable to consult a professional environmental inspection company. A certified specialist can conduct a thorough assessment of the chiller unit and its surroundings to identify any signs of mold growth or excessive moisture that could be contributing to these issues.

For immediate action, you might consider calling 800-MOLDS (or 800-66537) for an on-site inspection. Additionally, you can reach out to Saniservice at hello@saniservice.com for further guidance and remediation services if necessary. Regular maintenance of your chiller system is key; ensure that it’s serviced by certified professionals who understand the specific conditions in Dubai.

Remember, keeping the humidity levels low around the chiller area, ensuring proper drainage, and maintaining good ventilation can significantly reduce the risk of mold growth. If you notice any discoloration or musty odors, address these issues promptly to prevent further health risks for your family.
