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.

Does landlord cover duct sealing for damp smell?« Back to Previous Page

After the rain last month, I noticed a persistent damp smell coming from the hallway near the HVAC unit. My landlord assured me they would take care of it, but I’m not sure if that includes duct sealing. We’ve lived here for 2 years and just noticed this issue, so I want to make sure I’m not overlooking anything. Does my landlord have responsibility for duct sealing, or should I bring up the need with them specifically?

Duct sealing is indeed an important aspect of maintaining good indoor environmental quality. In the UAE and specifically Dubai, HVAC systems play a crucial role in keeping our living spaces comfortable, but they can also be breeding grounds for moisture issues if not properly maintained.

In your case, a persistent damp smell coming from near the HVAC unit could indicate a few potential issues such as duct leaks allowing cold air to escape, leading to condensation or perhaps an underlying moisture problem. While your landlord is responsible for ensuring that the building is in good condition and safe to live in, this often includes regular maintenance of the HVAC system.

However, it's not uncommon for landlords to have a limited understanding of all aspects of their property's maintenance needs. Duct sealing falls under the category of HVAC system maintenance and should be addressed if there are signs of moisture or other issues. The UAE Building Code (UAE Federal Law No. 17 of 2004) does not specifically mandate duct sealing as a regular service, but it is recommended to prevent air leaks and ensure efficient operation of the HVAC system.

Given that you've noticed this issue only now after living there for two years, I would recommend bringing up your concerns with your landlord. Explain the situation in detail and request a professional inspection by an HVAC specialist or a remediation company like Saniservice (call 800-MOLDS or email hello@saniservice.com if you need assistance). This will help identify whether duct sealing is indeed necessary and can provide peace of mind.

Regular maintenance, including duct sealing, is especially important in Dubai where the climate can be quite harsh. Proper sealing helps to reduce energy consumption by ensuring that air moves efficiently through the system without unnecessary loss.

Remember, ignoring moisture issues could lead to more serious problems such as mold growth or structural damage over time. Therefore, addressing this now might prevent bigger issues later on. It's always a good idea to have any concerns about your living conditions discussed directly with your landlord and potentially supported by professional advice.

Stay dry and safe!
