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.

Why won't mildew go away despite dehumidifier use?« Back to Previous Page

After the rain last month, I noticed a mildew stain forming on the ceiling of my living room. It started as a small spot but has grown to cover about half the area over the past few weeks. Despite using a dehumidifier and opening windows regularly, it doesn’t seem to be getting better. Has anyone else experienced this issue or have any tips on how to prevent mildew from recurring?

Cleaning rules and mildew removal can be quite the challenge, especially in our hot and humid climate here in Dubai. I've noticed a few issues that could explain why your mildew isn't vanishing despite using a dehumidifier. Firstly, just because you have a dehumidifier, it doesn't necessarily mean the air is being sufficiently dried out throughout your entire home. Many units can struggle to keep up with moisture levels when the outside humidity climbs, especially during rainy seasons.

Another factor could be the air circulation within your living room. Mildew thrives in areas that are damp and poorly ventilated. Even if you're opening windows regularly, if there isn't enough airflow, it might not be enough to combat the moisture. Consider using fans or a whole-house ventilation system to help with this.

Additionally, make sure you address any potential water leaks or condensation spots. In Dubai, AC units can sometimes cause excessive condensation, leading to dampness in walls and ceilings if they're not properly installed or maintained. Inspect your unit's drain line to ensure it is clear and functioning correctly. If you find any problems, contact a professional for repairs.

UAE specific regulations state that building owners should maintain their structures to prevent such issues, but sometimes it’s just hard to keep up with all the details. In my experience, it's always best to have an expert take a look at your property. A professional inspection can help pinpoint exactly where moisture is coming from and how to effectively tackle the problem.

Lastly, be mindful of what you're using to clean. Sometimes harsh chemicals can damage surfaces or leave residues that mildew loves to grow on. Opt for mild, natural cleaning solutions like white vinegar, baking soda, and water mixtures. These are effective at removing mildew without causing further damage.

If the situation persists, I strongly advise calling 800-MOLDS (800-66537) or emailing hello@saniservice.com for a professional assessment and remediation service. We can provide tailored solutions to ensure your home stays mold-free.

Remember, it's not just about getting rid of the mildew but also about preventing it from coming back. Proper maintenance and addressing underlying moisture issues are key.
