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.

Is poor duct cleaning causing mold growth?« Back to Previous Page

After the heavy dust storm last month, I noticed a persistent greyish film on the windowsills of our living room, which is right next to the HVAC ducts. My kids have been complaining of itchy eyes and runny noses since then, and I suspect it might be related to some mold growing in the vents. Could this be due to poor duct cleaning? What should we do to prevent this from happening again?

Yes, poor duct cleaning can indeed lead to mold growth. In the UAE, especially during dust storms like the one you experienced, uncleaned HVAC systems and ducts are prone to accumulating contaminants that can foster mold development. Mold thrives in damp environments - which is why it's a common issue post-dust storms when humidity levels rise.

In Dubai, as per the UAE Building Code 2018 (UAE-BC), HVAC systems must be regularly maintained to ensure indoor air quality and prevent health issues. This includes periodic cleaning of ducts and filters to remove dust, debris, and other allergens that can irritate sensitive individuals like your kids.

The greyish film you're seeing on the windowsills could very well be mold spores dispersing from the HVAC system. Mold not only poses a health risk but also deteriorates the quality of indoor air, leading to symptoms such as itchy eyes, runny noses, and respiratory issues—exactly what your kids are experiencing.

To address this issue, I strongly recommend calling in professional duct cleaning services. Saniservice, for instance, offers specialized treatments that can thoroughly clean your HVAC system, removing not only visible dirt but also mold and other allergens. Their team utilizes advanced techniques such as HEPA filtration to ensure the air you breathe is free from contaminants.

Moreover, it's crucial to address the underlying conditions that might be promoting mold growth. This includes ensuring good ventilation in your home to reduce humidity levels, checking for any water damage or leaks, and sealing gaps around windows and doors to prevent outside moisture from entering.

Regular maintenance of your HVAC system should also include replacing filters every 3-6 months and inspecting the ductwork annually by professionals. Doing so can significantly reduce the likelihood of mold growth and improve overall indoor air quality.

So, do not hesitate to contact Saniservice at 800-MOLDS or email hello@saniservice.com for a thorough inspection and cleaning service. Remember, clean air is crucial for your family's health, especially in such challenging environmental conditions as the recent dust storm.
