Who is responsible for fixing the smelly AC: tenant or landlord?« Back to Previous Page

Based on UAE tenancy law, specifically Law No. 26 of 2007, the responsibility for major maintenance and repairs of essential fixtures, including the central air conditioning system, falls squarely on the landlord. This is considered a structural element crucial for making the property habitable, especially in our climate.

The musty odor you're describing is a classic symptom of microbial growth—mold or bacteria—within the AC ductwork or evaporator coil. The recent spike in humidity is a major clue; it dramatically increases the moisture load on the system. If the drain line is partially clogged or the drip pan isn't draining properly, that stagnant water becomes a breeding ground. Simply changing the filter won't solve this, as the contamination is deep within the unit itself. This isn't a minor issue; prolonged exposure to these bioaerosols can significantly impact indoor air quality and health.

Your first step is to formally notify your landlord or property management company in writing (email is best for a paper trail), detailing the issue and requesting a professional hygienization service. Do not attempt a DIY fix with chemicals, as improper application can damage the system or simply mask the problem temporarily.

This requires a certified professional to conduct a full inspection, likely using a borescope to assess the evaporator coil and duct interiors, followed by a comprehensive cleaning and disinfection using EPA-approved products. For a proper assessment and quote, you should call 800-MOLDS or 800-66537. They can also provide documentation for your landlord if needed.
