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 AC unit post-storm causing mildew odor?« Back to Previous Page

After the heavy rain last month, I noticed a strange odor coming from the air vents in my living room. It smells like mildew and has persisted even after cleaning everything thoroughly. The AC unit is located right next to the window that got damaged during the storm. Could this be related to the filter needing replacement?

Yes, it sounds like your AC unit might be the culprit for the mildew odor coming from your vents. The storm you experienced caused damage to the window near your AC unit, which could have introduced moisture into the system. In the UAE and Dubai, humidity can still be high even after rain, especially during summer months.

When there's excess moisture in an HVAC system, it can create a perfect environment for mold and mildew growth. This is particularly common with air conditioning units that haven't been checked or cleaned since the storm. The filter might have become saturated with water, leading to this issue. It’s important though to ensure no other parts of your AC unit were damaged during the storm.

Before you replace the filter yourself, it's advisable to get a professional inspection. In Dubai and UAE, regulations require that HVAC systems are maintained regularly for both comfort and health reasons. A professional can also check if any other components in your system have been compromised by water damage and need repair or replacement.

You may want to call 800-MOLDS (800-66537) or email hello@saniservice.com to schedule an inspection. They are experienced with handling such cases, especially after natural disasters like heavy rainstorms.

Once you get the go-ahead from a professional, replace the filter and any other parts that were affected by moisture. Ensure your AC unit is properly cleaned and disinfected. It’s also beneficial to check for leaks in the system and make sure all connections are tight.

Regular maintenance of your HVAC system can help prevent such issues in the future. In Dubai, it's common practice to have an inspection done twice a year – once before summer and once before winter when you start relying heavily on AC or heating systems.

Remember, maintaining proper air quality is crucial for health, especially with conditions like mold which can cause respiratory problems. Keep your home well-ventilated if possible, but ensure the ventilation system itself isn’t causing issues.

Stay proactive about your HVAC maintenance to avoid such unpleasant situations in the future!
