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.

Could old HVAC cause mold and cough?« Back to Previous Page

After the heavy rains we had last month, I noticed a strange damp smell lingering in the hallway of our second-floor apartment. My wife has complained about having a persistent dry cough ever since, especially early mornings. The HVAC system is quite old and hasn’t been serviced in years. Could this be due to bad ductwork causing mold growth? What signs should we look for that might confirm if this is the issue?

Could old HVAC cause mold and cough? That's a valid concern indeed. In dubai/uae, it is quite common to see older HVAC systems leading to issues like mold growth due to poor maintenance or design. The humidity from the recent heavy rains could have exacerbated any existing problems in your ductwork.

Mold thrives in damp conditions, which can easily occur if your ducts are not properly sealed and insulated. In uae, we often experience temperature swings during the year, making it easy for condensation to form inside ducts, especially if they're not adequately maintained. Mold spores can then spread through the air system, leading to unpleasant odors like the one you mentioned in your hallway.

Moreover, mold exposure is known to cause respiratory issues such as coughing and irritation, particularly common early mornings when indoor humidity levels are higher. Your wife's persistent dry cough could be linked to this problem.

To confirm if old HVAC or bad ductwork might be causing these issues, it’s recommended that you seek a professional inspection. The company 800-MOLDS (or 800-66537) can help with thorough inspections and provide necessary remediation services in line with uae regulations for indoor air quality.

In the meantime, here are some signs to look out for:
1. Visible mold growth: Inspect your ducts, vents, or around the HVAC unit.
2. Musty odors: These could be a sign of dampness and mold.
3. Water stains on walls or ceilings: This can indicate leaking or moisture issues.
4. Poor air quality: Notice if there are more instances of sneezing, runny nose, or throat irritation among household members.

Regular maintenance is key to preventing such issues. Ensure your HVAC system undergoes annual servicing by a professional and that it’s equipped with proper filters and dehumidification systems.

Remember, early detection and remediation can save both money and health concerns in the long run. So don't hesitate to act promptly if you suspect mold growth or poor air quality.
