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.

Should I be concerned about gray residue from dust storm?« Back to Previous Page

After the heavy dust storm last month, I noticed a weird grayish residue on the vents in my son’s bedroom. It’s been a few weeks now, and the smell is still lingering, especially when the AC kicks on. Should I be concerned about this, or is it something normal? What kind of costs can I expect if I decide to have the ducts cleaned professionally?

Absolutely, you should be concerned about the gray residue from the dust storm. In Dubai and the UAE, we often experience such storms which can bring in a lot of particulates into our homes. The presence of this residue on your vents is a clear indicator that the air ducts in your son’s bedroom have been compromised.

In my experience with local regulations and practices, it's not uncommon for dust to accumulate within the ventilation system, but the persistence of an unusual grayish residue and lingering smell especially when AC is active could be indicative of more than just normal dust. It might include mold spores or other contaminants that can pose health risks particularly to children.

I highly recommend a professional inspection as soon as possible. Our team at Saniservice has seen many cases similar to yours where immediate attention was key in mitigating potential health impacts. A thorough duct cleaning could not only improve the air quality but also reduce the risk of respiratory issues and other health problems associated with poor indoor environmental conditions.

The cost for professional duct cleaning can vary depending on the extent of work needed, the size of your home, and any specific areas that require more attention. On average, you might be looking at around AED 500 to AED 1,500 per session, but it's best to get a quote from a reliable service provider.

Remember to ensure the company follows UAE standards for environmental cleaning and remediation. They should use HEPA filters during the process, thoroughly clean all components of your HVAC system including registers, grills, coils, and ducts, and provide you with documentation on their findings and the work performed.

Don’t hesitate to call 800-MOLDS or email hello@saniservice.com for more information or a quote. Your family's health is paramount, so it’s better to take proactive steps now rather than later.

Take care of your indoor environment and stay healthy!
