Is constant AC running and dripping sound a mold issue?« Back to Previous Page

The AC in my apartment seems to be running constantly, even when it's not very hot outside. This is unusual because usually it only kicks on at night. Today, as I was walking through the living room, I heard a faint dripping sound coming from near the vent by the stairs where the kids play after school. My 6-year-old has been coughing more than usual lately and seems to be getting worse despite trying to keep the house clean. Could this be a sign of mold or some other issue that might affect my family’s health?

The constant running of the AC and the dripping sound from near your stairs vent could indeed be indicative of a moisture-related issue that might lead to mold growth. In the UAE context, especially Dubai, high humidity levels can exacerbate such issues, particularly during cooler months or if there's an increase in water use like after heavy rainfall.

Mold spores thrive in warm, humid environments with ample moisture and organic material for sustenance. Given your observation of a dripping sound from around the vent, it suggests that excess moisture is present within the HVAC system or nearby areas, potentially leading to mold colonization. Additionally, the increase in coughing among family members could be linked to exposure to these airborne spores.

To properly diagnose and address this issue, a professional environmental inspection by a certified company such as Saniservice (call 800-MOLDS or email hello@saniservice.com) is highly recommended. They can conduct thorough tests for mold presence, assess the HVAC system's condition, and identify any underlying issues causing the moisture build-up.

In the meantime, it would be prudent to take some initial steps:
1. Ensure proper ventilation in your living area by opening windows when feasible.
2. Check if there are any leaks or water damage around the vent location and address them promptly.
3. Keep a close eye on indoor humidity levels; using a dehumidifier can help reduce moisture, especially during cooler months.

Remember that addressing mold issues is not just about cleaning visible mold but also ensuring the environment remains free from conditions conducive to its growth. Regular maintenance of your HVAC system and prompt attention to any water-related concerns are key in preventing such problems.
