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 mold growing inside air ducts causing smell?« Back to Previous Page

After the heavy rains last month, I noticed a strange moldy smell lingering in the air ducts of our penthouse. Every time we turn on the AC, it’s even more noticeable. The problem seems to be coming from the supply vent in the bedroom. Have any of you experienced similar issues and know how to fix it?

It sounds like you might be dealing with a common issue that many in the UAE face, especially during the wet seasons. Yes, mold growing inside air ducts can indeed cause a musty smell, particularly when the AC is running. In Dubai and other parts of the UAE, we experience periods where humidity levels rise significantly, leading to condensation within HVAC systems and potentially causing mold growth.

Mold thrives in damp environments, and with heavy rains last month, it's not surprising that you're encountering this issue. The smell emanating from your bedroom supply vent suggests that moisture may be trapped or poorly distributed within your ductwork. This can also affect the overall air quality and comfort of the space.

Given the seriousness of mold growth, it’s highly recommended to get a professional inspection as soon as possible. In the UAE, regulations like those found in the Building Code of Dubai (BCD) require proper maintenance and inspection of HVAC systems to ensure they do not compromise indoor environmental quality. The BCD stipulates that air ducts should be free from contaminants such as mold and bacteria.

To help address the issue temporarily until you can arrange for a professional, try cleaning your AC filters regularly. Ensure that any visible dampness or standing water in the air conditioning system is addressed to prevent further mold growth. Additionally, consider running the fan on high speed without cooling or heating to help dry out the ducts and vents.

For long-term solutions, contact a reputable environmental inspection and remediation company such as Saniservice. They can perform thorough assessments of your HVAC system and provide necessary treatments for any existing mold colonies. Their services are available through their hotline 800-MOLDS (800-66537) or by emailing hello@saniservice.com.

Remember, addressing this issue promptly is important not only to improve the air quality but also to protect your health and that of your family. Don't hesitate to act quickly to resolve this situation.
