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 AC unit cause musty smell after storms?« Back to Previous Page

After the heavy storms we had last month, I noticed a strange musty smell lingering in our nursery. It’s really concerning because my children spend so much time there. The area under the window seems particularly bad, and it looks like some mildew is starting to form. Has anyone else experienced this issue with their AC unit after such weather?

Yes, AC units can indeed cause musty smells after storms. In our region of Dubai/UAE, we have experienced similar issues post heavy rainfall and strong winds. The moisture that enters the building via open windows or through leaks can foster mold growth, leading to those unpleasant odors.

In your case with the nursery, it's important to note that UAE regulations require buildings to be equipped with proper ventilation systems designed to handle such conditions. However, after storms, it’s crucial to inspect not just the AC unit but also any areas where water may have pooled or been absorbed into materials like carpets or wall panels.

The area under the window seems particularly suspect. This spot could indicate an issue with condensation buildup from the AC system. When air conditioning units run, they dehumidify the air, producing condensate. If drainage is poor, this moisture can accumulate and create a breeding ground for mold spores.

I recommend having a professional inspection done to ensure that there are no leaks or improper ventilation issues in your nursery. The UAE has stringent standards regarding indoor environmental quality (IEQ) which cover areas such as humidity levels, temperature control, and air quality. Ensuring compliance with these regulations is key to maintaining a healthy environment for children.

Moreover, addressing the musty smell should not be taken lightly given that children are more susceptible to respiratory issues. If you notice any discoloration or mildew growth, it’s essential to act quickly to avoid potential health risks.
