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.

Can sealing ducts fix basement mustiness?« Back to Previous Page

After the heavy rains last month, I noticed a musty smell creeping into our basement, even though we don’t use it much. My partner suggested it might be due to water damage seeping in through gaps around the ducts, but I’m not sure how to address it. Has anyone here dealt with similar issues and can advise on sealing those ducts properly?

Sealing ducts can indeed be part of the solution for basement mustiness, but it's just one piece of the puzzle. In dubai/Uae, we've seen many cases where moisture and dampness issues are often linked to gaps or cracks around HVAC ductwork in basements or crawl spaces.

Firstly, before jumping into sealing, a professional inspection is recommended. The local building regulations might not be stringent enough to cover all residential conditions, so having an expert assess the situation can ensure you're tackling the right areas. Here at Saniservice, we've found that water damage seeping in through gaps around ducts is quite common and can definitely contribute to that musty smell.

If your inspection confirms that moisture infiltration is indeed coming from outside through these gaps, sealing them would be a good start. You'll want to use a specialized sealant designed for HVAC systems; standard home caulk might not provide the necessary durability against humidity or temperature changes. We recommend using an expanding foam sealant which can create a tight, long-lasting seal.

However, duct sealing alone may not fully address your issue. In many cases, particularly after heavy rains like you experienced, it's crucial to look at other areas too. Check for any water leaks in pipes, windows or doors, and make sure the basement has adequate ventilation. If the area is damp, consider installing a dehumidifier or a whole-house fan system to help reduce moisture levels.

Remember that in Dubai/UAE, humidity can be quite high especially during certain times of the year so maintaining proper indoor air quality throughout your home remains important for preventing mustiness.

If you're not sure where to start or how to proceed, don't hesitate to give us a call at 800-MOLDS (800-66537) or send an email to hello@saniservice.com. We're here to help and can provide tailored advice based on your specific situation.

Lastly, always ensure any sealing work is done by professionals who are familiar with local climate conditions and regulations, as this can vary across the uae/Dubai region.
