UAE Residents Warned: Dirty AC Systems Can Trigger Allergies, Respiratory Issues

As the summer months approach in the UAE, residents are being urged to check their air conditioning systems to prevent potential health risks. With the rising temperatures, many residents are relying heavily on their ACs, unaware that poorly maintained systems can contribute to indoor air pollution, triggering allergies, headaches, and respiratory issues.

According to experts, the UAE's hot and humid climate creates an ideal environment for mold and bacteria to grow inside poorly maintained AC systems. Dr. Sherin Hussain, a specialist in internal medicine at Medeor Hospital, Abu Dhabi, warned that dirty AC systems can worsen symptoms such as coughing, allergies, nasal congestion, headaches, and shortness of breath. This occurs when dust, mold, and moisture build up inside filters and air ducts, circulating through indoor air.

The buildup of mold and bacteria in AC systems is often caused by a mix of heat, humidity, trapped moisture, and dust accumulation inside the unit. Over time, untreated filters, ducts, and drain pans can reduce airflow and cooling efficiency while circulating contaminants indoors. Maintenance companies have reported a significant increase in resident inquiries related to mold buildup during the summer months, with up to 30% of homes experiencing some form of mold buildup inside AC systems.

Children, elderly residents, asthma and allergy patients, and people with weaker immune systems are among the most vulnerable groups. Experts recommend that residents service their AC systems before peak summer usage and clean or replace filters regularly. Families are also advised to watch out for musty smells, fix leaks or condensation issues quickly, and monitor recurring symptoms, especially if they improve after leaving the house.

Residents can also help reduce moisture buildup by avoiding switching off AC systems for long periods during humid months and keeping temperatures between 26°C and 28°C in fan or auto mode. As summer temperatures climb further across the UAE, experts emphasize that AC maintenance is no longer just about comfort, but also about maintaining healthier indoor air quality.

In addition to regular maintenance, residents can take steps to prevent mold growth and reduce indoor air pollution. This includes ensuring proper ventilation, using a dehumidifier, and avoiding the use of strong chemicals or pesticides indoors. By taking these precautions, residents can minimize the risks associated with poorly maintained AC systems and create a healthier indoor environment for themselves and their families.

The UAE's climate and geographic location make it prone to extreme temperatures and humidity levels, which can exacerbate the growth of mold and bacteria in AC systems. As the country continues to experience rapid growth and urbanization, the importance of maintaining good indoor air quality cannot be overstated. By prioritizing AC maintenance and taking proactive steps to prevent mold growth, residents can protect their health and well-being, particularly during the hot summer months.
