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.

Who pays for duct sealing in rentals?« Back to Previous Page

After the heavy storms we had last month, I noticed a persistent damp smell coming from the ceiling of the living room. The landlord mentioned that they were looking into sealing some ducts in the building, but I’m not sure if this is something my landlord should be taking care of or if it’s part of their responsibility as a tenant. Could anyone give me advice on who typically handles duct sealing in rental properties?

Duct sealing can be a crucial step to improve indoor air quality and energy efficiency. In the UAE, especially in Dubai, landlords are typically responsible for maintaining the overall condition of the property, which includes ensuring that the HVAC system is functioning properly. This means they should also address issues like duct leaks or damage that could lead to damp smells.

However, who specifically pays for duct sealing can vary based on several factors including the terms of your lease agreement and local regulations. In general, if a leaky duct is discovered as part of regular maintenance or due to normal wear and tear, it would be the landlord's responsibility to take care of it. But, if the issue was caused by tenant activity or negligence, then you might need to share costs.

In Dubai, there are no specific regulations mandating that landlords pay for duct sealing unless it’s part of a larger maintenance schedule. However, it is advisable to check your lease agreement to see what exactly is covered under maintenance and repairs. If the agreement doesn't specify, it's best to discuss with your landlord about who will cover the cost.

If you're experiencing persistent damp smells or other issues, consider calling in a professional for an inspection before deciding on duct sealing. At Saniservice, we offer comprehensive indoor environmental quality assessments which can help identify the source of odors and provide recommendations. You can reach us at 800-MOLDS (800-66537) or email hello@saniservice.com for more information.

Remember that proper maintenance is key to a healthy living environment, so it’s worth investing in professional services if the smell continues despite your landlord's efforts.
