Why is professional AC cleaning important in Dubai homes and offices?

Dubai’s climate creates constant high humidity inside AC systems, which encourages microbial growth. Without proper cleaning, AC units can circulate contaminants throughout indoor spaces.

How is Saniservice different from standard AC cleaning companies in the UAE?

Most AC cleaners focus on visible dust. Saniservice follows a scientific indoor environmental remediation process that targets microbial sources, moisture behavior, and airflow contamination.

Is AC mould common in Dubai buildings?

Yes. Due to year-round AC use, high humidity, and sealed buildings, AC-related microbial growth is extremely common in Dubai residential and commercial properties.

Why does simple AC duct cleaning often fail to solve air quality issues?

Duct cleaning alone does not address coils, drain pans, humidity imbalance, or microbial reservoirs. Without correcting these, contamination quickly returns.

How does Saniservice assess whether an AC system is contaminated?

We begin with system inspection and risk assessment, examining moisture patterns, airflow paths, and areas prone to microbial growth rather than relying on visual assumptions.

Why is fogging not an effective AC disinfection method?

Fogging treats air temporarily but does not remove contamination from coils, drains, or surfaces where microbes grow. It masks symptoms without solving root causes.

Can bleach be used safely inside AC systems?

Bleach fails because it does not penetrate biofilms, can corrode components, and does not correct humidity conditions that allow regrowth.

How does humidity affect AC hygiene in the UAE climate?

Humidity is the primary driver of microbial growth. Without addressing moisture behavior inside the system, cleaning alone will not deliver lasting results.

What does “medical-grade AC disinfection” actually mean?

It refers to controlled cleaning and disinfection methods aligned with indoor environmental health standards, not perfumes or cosmetic sanitizers.

How does Saniservice verify that AC cleaning was effective?

Where required, we use pre- and post-intervention validation methods to confirm that contamination levels have been meaningfully reduced.

Is AC cleaning necessary even if there is no visible mould?

Yes. Microbial contamination often exists inside coils and drains long before visible signs appear, especially in Dubai’s climate.

How often should AC systems be cleaned in Dubai?

Frequency depends on usage, humidity levels, and building type, but most UAE properties require more frequent intervention than cooler climates.

Can poor AC hygiene affect health?

Contaminated AC systems can circulate microbial fragments and irritants that may worsen respiratory symptoms and indoor comfort.

Why does Saniservice sometimes clean less than other companies?

Our methodology focuses on correct intervention. We avoid unnecessary disturbance that can spread contamination or damage system components.

Is this service suitable for villas, apartments, and commercial buildings?

Yes. The same scientific principles apply across residential, commercial, and sensitive environments in the UAE.

How does Saniservice handle AC cleaning in occupied spaces?

We use controlled procedures designed to minimize disruption and prevent the spread of contaminants during cleaning.

What role does airflow play in AC contamination?

Improper airflow allows moisture and particles to settle, creating ideal conditions for microbial growth inside the system.

Can AC cleaning reduce recurring odours?

Yes, when odours are caused by microbial growth or trapped moisture, addressing the source eliminates the problem rather than masking it.

Why is source identification important before disinfection?

Disinfection without understanding the cause leads to recurrence. Our process identifies why contamination formed in the first place.

Who should consider Saniservice’s AC cleaning and disinfection service?

Clients in Dubai who prioritize verified indoor air quality, occupant health, and long-term building performance rather than superficial cleaning.

Does landlord need to clean HVAC ducts?« Back to Previous Page

After the rain last month, I noticed a persistent moldy smell coming from the living room vents. My landlord hasn’t mentioned anything about cleaning the ducts since we moved in two years ago. The filters are clean, but the smell persists even after running the AC for hours. Should I bring this up with my landlord, or is it something that falls under their maintenance responsibilities?

Absolutely, it's understandable to be concerned about the moldy smell coming from your living room vents. In Dubai and the UAE, maintaining indoor air quality is crucial, especially given our climate conditions. According to local regulations, landlords are generally responsible for ensuring that the HVAC system in rental properties is in good working condition and free from issues such as mold growth.

The moldy smell you're experiencing could indicate a need for duct cleaning. Even though your filters are clean, it's possible that mold or other contaminants have built up within the ductwork itself over the past two years. Ducts can accumulate dust, debris, moisture, and unfortunately, mold if not properly maintained, leading to unpleasant odors and potential health risks.

In Dubai, regulations mandate regular cleaning of HVAC systems to prevent such issues. However, it's important to note that just because a landlord hasn’t mentioned anything doesn't necessarily mean they are neglecting their duties. It’s still wise to bring this up with your landlord as part of routine maintenance discussions.

However, if the smell persists despite clean filters and regular usage of the AC, I would recommend considering a professional inspection. Companies like Saniservice can provide thorough duct cleaning and ensure that all areas of your HVAC system are free from contaminants. They can also offer advice on how to prevent such issues in the future.

Remember, maintaining good indoor air quality is not just about comfort; it’s essential for your health and well-being. So, if you decide to go ahead with a professional inspection or cleaning, don’t hesitate to get multiple quotes from reputable companies like Saniservice.

If you feel uncomfortable discussing this directly with your landlord, consider writing them an email detailing the issue and suggesting a professional inspection. This approach can help ensure that the matter is addressed without any conflict.

Call 800-MOLDS or 800-66537 for more information on how to proceed or email hello@saniservice.com to schedule a consultation.

Hope this helps!
