Expert Guide by Microcare – Dubai’s Trusted AC Cleaning Specialists
Dubai’s hot and dusty weather puts extra pressure on air conditioners. Even if your AC seems to be working, dirty coils can silently reduce cooling, increase your electricity bill, and damage internal parts. Unlike other countries, AC coil cleaning in Dubai is not optional ,it is necessary for system health and indoor comfort.
At Microcare, we receive hundreds of service calls every month where customers complain about weak cooling, high DEWA bills, or strange AC smells. In most cases, the root cause is one thing:
Dirty AC coils
What Are AC Coils & Why Do They Get Dirty in Dubai?
An AC system has two main coils:
Evaporator Coil (Indoor)
This coil absorbs heat from the indoor air. When dust builds up on it, cooling efficiency drops.
Condenser Coil (Outdoor)
This coil releases heat outside. Sand, dust, and humidity create thick dirt layers that block airflow.
Dubai’s dusty desert environment, construction areas, and high humidity make coil dirt build-up faster than other places in the world — that’s why coil cleaning must be done more often here.
5 Clear Signs You Need AC Coil Cleaning in Dubai
1. Weak or Delayed Cooling
If your AC runs for 30–60 minutes but still doesn’t cool the room properly, the AC coil is most likely blocked with dust.
Dust acts like insulation and stops heat transfer, meaning your AC must work harder to produce the same cooling.
How Microcare fixes it:
We deep clean evaporator and condenser coils using chemical foam and pressure cleaning to restore original cooling performance.
2. Sudden Increase in DEWA Electricity Bills
Dirty coils = More running time = More electricity consumption
This is one of the first signs Dubai residents ignore.
Even 10% dirt on the coils can increase AC energy usage by 20–30%.
If your DEWA bill jumps without increasing AC usage, coil cleaning is urgently needed.
Microcare Benefit:
After coil cleaning, most customers report lower bills within the same month.
3. Ice or Frost Forming on AC Pipes or Indoor Unit
Ice on the evaporator coil is a MAJOR warning sign.
It means your coil is not receiving proper airflow due to dust blockage, which freezes the refrigerant.
If you keep using the AC like this, the compressor can burn, leading to AED 1,500–4,000 repair cost.
Microcare Tip:
If you see ice or water dripping from the unit — TURN OFF the AC and call us immediately.
4. Strange Smell or Dusty Odor from the AC
Dusty coils trap moisture, bacteria, and mold.
This causes:
Bad smell when you turn on AC
Allergies and sneezing
Breathing discomfort
This problem is common in apartments, villas, and offices near Dubai Marina, Business Bay, JVC, and Al Barsha due to humidity and closed indoor environment.
Microcare removes:
- Mold growth
- Dust layers
- Bacteria buildup
So your AC blows clean, fresh air again.
5. AC Turns ON and OFF Frequently (Short Cycling)
If your AC turns OFF within 2–3 minutes and restarts again — the system is struggling.
Dirty coils cause heat buildup, forcing the AC to shut down for safety.
This damages:
Compressor
Fan motor
Electrical board
Short cycling ALWAYS means the coil is dirty ,and cleaning is needed immediately.
Why AC Coil Cleaning Is Especially Important in Dubai
Extreme Heat + Dust = Fast Coil Blockage
Due to year-round AC usage, coils collect:
- Dust
- Sand
- Mold
- Pollution particles
- Kitchen fumes
- Pet hair
Dubai’s climate makes coil cleaning necessary every 6–8 months (not once in 2 years like other countries).
Dirty Coils Affect Your Health
Dust + moisture = bacteria and fungus
This causes:
Asthma triggers
Skin irritation
Eye discomfort
Bad indoor air quality
Clean coils improve air quality and protect your family.
Increases AC Life & Reduces Repair Cost
Regular coil cleaning prevents:
- Compressor failure
- Gas leaks
- Motor overheating
- Fan damage
A clean AC can last 10+ years. A dirty one may fail in 4–5 years.
