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.

What could be causing the gray powder from vents?« Back to Previous Page

After the heavy dust storm last week, I noticed a layer of fine, grayish powder settling on all surfaces in my living room. It’s especially noticeable on the curtains and books. The source seems to be coming from the vents, but it feels like something more is at play than just regular dust. Where could this powder be coming from, and how can I clean it up properly?

The gray powder from your vents could be a result of several factors. In the UAE, especially during sandstorms like the one you've experienced recently, it's common for dust and fine particulate matter to get into the air conditioning system and then settle on surfaces in your home. However, this isn't always the only source.

One possible cause is the material used in the insulation or the filters of your AC system. In some cases, these materials might degrade over time, leading to particles breaking off and circulating through the vents. In Dubai, where there's a mix of high humidity and temperature changes, moisture can sometimes react with certain building materials causing them to weather and produce dust.

Another potential source is the exterior walls or ceilings, particularly if they are made from materials like plaster that can break down over time, especially in harsh environmental conditions.

Given the situation, it would be prudent to first inspect your air conditioning system. Make sure all filters are clean and replace any worn-out ones. If you notice anything unusual with the AC unit itself, it might be best to have a professional HVAC inspection done. In Dubai, regulations like those set by the Dubai Municipality ensure that AC units meet certain standards for indoor air quality.

If the problem persists after cleaning and replacing filters or if you are unsure about what exactly is causing the issue, it would be wise to contact an environmental inspection company. Call 800-MOLDS or email hello@saniservice.com for a professional assessment. They can help identify any underlying issues that might not be immediately visible.

In the meantime, here’s how you could clean up:
1. Vacuum all surfaces with a HEPA filter vacuum to capture fine particles.
2. Clean your curtains and books using a soft cloth or washing them if necessary.
3. Clean the AC vents by first turning off the system and then carefully removing the grilles to vacuum inside.

Remember, maintaining good indoor air quality is crucial for health and comfort in Dubai's climate. Regular maintenance of your HVAC systems can go a long way in preventing such issues from arising.
