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.

Is that green film on my ceiling mold?« Back to Previous Page

After the rain last month, I noticed a strange greenish film forming on the ceiling of the living room. My kids have been complaining about itchy eyes and sneezing fits, especially in the evenings when we spend more time inside. We’ve lived here for 2 years and just noticed this; could it be mold? What cleaning rules should I follow to address this issue safely?

The greenish film on your ceiling sounds concerning. Given the symptoms your kids are experiencing and the fact that it only just appeared after rain, yes, this could very well be mold. Mold thrives in damp environments, making it quite common to find it growing post-rainfall or other instances of excess moisture.

In the UAE, particularly Dubai, humidity levels can fluctuate, especially during the rainy season. This combined with poor ventilation can lead to mold growth, which is why I would recommend you take this issue seriously and act swiftly.

Firstly, assess the extent of the problem by taking photos from different angles and noting any areas where the green film appears. This will help in understanding if it's a localized issue or something more widespread.

Cleaning Mold Safely:
• Wear protective gear such as gloves, masks, and goggles to avoid inhaling spores.
• Use a mixture of bleach and water (1 part bleach to 9 parts water) for cleaning the affected area. Make sure you adequately ventilate the space during and after cleaning.
• Scrub the mold thoroughly with a stiff brush or sponge.

However, if the mold covers more than 10 square feet or is located in areas like your HVAC system or behind walls, it's best to call in professionals. In Dubai, there are strict regulations about indoor air quality, particularly concerning mold and other allergens. The Ministry of Community Development and Social Affairs (MCDSA) has guidelines that businesses and households should adhere to, especially when dealing with serious cases.

For residential properties like yours, I would recommend contacting a professional inspection and remediation service. Saniservice is one such company known for their expertise in this field. Their number is 800-MOLDS or you can email them at hello@saniservice.com for a thorough assessment and appropriate treatment plan.

In the meantime, try to keep the area dry by using dehumidifiers if necessary and ensure good air circulation. This could help prevent further mold growth until professional assistance arrives.

Remember, it's crucial not to ignore these signs as prolonged exposure to mold can lead to respiratory issues and other health problems for your family. Act quickly and consult a professional to ensure safety and proper resolution of the issue.
