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.

Should I worry about AC fog and mildew?« Back to Previous Page

The AC in my apartment seems to be struggling more this summer than usual. After turning it on, there’s a noticeable foggy cloud that comes out of the vents, and sometimes it smells like mildew. It’s been happening for about a week now, and I’m worried it might not just be a temporary issue. Should I call in an HVAC professional or is there something I can check myself?

Absolutely understandable to be concerned about the condition of your AC system, especially during the sweltering summer months here in Dubai. The fog coming out of the vents and the mildew smell can indeed indicate a few potential issues that might need professional attention.

Firstly, let's talk about what you've experienced: the 'fog' or moisture is often caused by warm air from your AC system mixing with cold air, creating condensation. This is usually not an issue, but if it's happening excessively and accompanied by a musty smell, there might be something more serious going on.

In Dubai, it’s common for humidity to rise during summer, which can lead to moisture accumulation in poorly maintained systems or even indicate an internal leak in the AC unit itself. If your AC is older or hasn’t been serviced regularly, it could also harbor mold and mildew – these organisms thrive in warm, humid environments like air ducts.

Given that you've noticed this issue for about a week now, it might be prudent to call in a professional HVAC technician. They can inspect the system thoroughly, ensuring everything is running efficiently and checking for any signs of leakage or contamination. In Dubai, regulations do stipulate that AC systems should be maintained annually to ensure they are operating at their best and to prevent issues like mold growth.

If you're unsure about what steps to take next, I'd recommend reaching out to us at 800-MOLDS or emailing hello@saniservice.com. We can provide a free consultation and help guide you through the process of ensuring your indoor air quality is top-notch.

Remember, maintaining good indoor air quality isn't just about comfort—it's crucial for health. By addressing these issues promptly, you can avoid potential long-term effects from mold exposure, which can lead to respiratory problems.

Take care and stay cool!
