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 greenish-black substance on ceiling mold?« Back to Previous Page

After the heavy rain last month, I noticed a strange greenish-black substance growing on the ceiling near our bedroom window. It’s only in one corner, but it looks pretty concerning, especially since my kids have been complaining of constant coughing. Is this something that should be addressed by the landlord or am I overthinking it?

The greenish-black substance on your ceiling sounds like it could be mold. Mold is quite common in the UAE, especially after heavy rains like the ones we had last month. The presence of such a substance can indeed be concerning, particularly if it's near where your children are sleeping and they're experiencing persistent coughing.

In the UAE, including Dubai, mold growth is regulated by various health and safety standards to ensure the well-being of residents. According to the UAE Ministry of Health and Prevention (MoHP) guidelines, dampness and moisture issues must be addressed promptly to prevent the proliferation of mold. Failure to do so can lead to respiratory problems, allergies, and other health concerns, especially for children.

Given that you've noticed this growth near your bedroom window after a rainfall event, it's quite likely that excess moisture has contributed to the mold development. Mold thrives in damp environments, making windowsills and corners prone to such issues.

It is highly recommended that you call 800-MOLDS or 800-66537 for professional inspection and remediation services. This will allow an expert to assess the situation accurately and provide necessary treatment to prevent further growth. At Saniservice, we offer comprehensive mold testing, removal, and prevention solutions tailored to local conditions.

In the meantime, you can take some initial steps:

1. Ensure adequate ventilation in your home.
2. Clean any visible mold with a solution of water and detergent or a mixture of vinegar and water. Be sure to wear gloves and protective clothing.
3. Address potential moisture sources like leaky pipes or poor drainage.
4. Keep the area dry, as prolonged dampness can encourage further growth.

Remember, while these steps may help manage mild cases, they are not substitutes for professional intervention in serious situations. Given your family's health concerns and the persistent nature of the mold, contacting a professional is essential to ensure proper treatment and prevent future issues.

If you decide to seek our services, please don't hesitate to email hello@saniservice.com or give us a call at 800-66537. We're here to help keep your home safe and healthy for everyone living there.
