What Affects Chemical Wash Pricing?
1. Unit Type and Complexity
Wall-mounted units are the industry standard and generally the most affordable to service. Ceiling cassette units, often found in shops or larger living rooms in Menjalara or Desa ParkCity, require significantly more labor to dismantle and clean properly. Ducted systems involve specialized access panels and often require a two-person team.
2. Unit Size (Horsepower)
Larger units possess bigger evaporator coils and blower fans that collect more grime. A 2.5HP unit in a living room processes roughly twice the air volume of a bedroom’s 1.0HP unit. This increased surface area demands more chemical solution and scrubbing time to clear fully.
3. Service Depth: Wash vs. Overhaul
We find that many homeowners confuse a standard chemical wash with a full chemical overhaul. A chemical wash cleans the unit while it remains on the wall using a catchment bag. An overhaul involves pumping down the gas, dismantling the entire unit, and soaking individual parts to remove hardened “jelly” or stubborn oxidation.
4. Location & Access Challenges
Condos with strict management rules or units installed above stairwells often incur small surcharges. High-rise access in buildings like The Henge or Fortune Perdana may require additional setup time for ladders and safety gear.

What Should Be Included in Chemical Wash
When comparing prices, make sure you’re comparing apples to apples. A proper chemical wash should include:
Standard Inclusions:
- ✅ Dismantling the indoor unit casing
- ✅ Chemical cleaning of evaporator coils (using safe, alkaline-based cleaners)
- ✅ Chemical cleaning of the fan blower roller
- ✅ Scrubbing of filters and covers
- ✅ Vacuuming and flushing the drainage system
- ✅ Wiping down the exterior
- ✅ Function testing and airflow check
Often Charged Extra:
- Gas top-up (typically RM50-100 for R410A or R32)
- Outdoor unit cleaning (RM30-50)
- Part replacement (capacitors, sensors)
AC Service Pro Difference:
Our team believes in complete transparency. Gas top-up is FREE with every chemical wash we perform. That is typically RM80+ value included at no extra charge, ensuring your unit runs cold immediately.
Price Comparison: What Others Charge
Based on our market research in Kepong and surrounding areas:
Budget Providers (RM80-100)
These offers often appear in neighborhood Facebook groups or mailbox flyers. The low entry price frequently excludes essential steps like drainage flushing. Gas top-up is almost always an extra charge, pushing the final bill well above RM150. Warranties are rare or very short (3 days).
Mid-Range Providers (RM100-150)
This tier represents the standard market rate for professional technicians. You can expect a thorough job using proper catchment bags to protect your walls. Most companies in this range offer a 7-14 day workmanship warranty.
Premium Providers (RM150-200+)
Services at this level often include deep steam cleaning or full dismantling (overhaul). The technicians usually carry advanced diagnostic tools to check compressor health. A 30-day warranty is standard for this price point.

Hidden Costs to Watch Out For
Some providers advertise low prices but add charges later:
The “Gas Leak” Bluff
Unethical technicians may claim your gas is empty and charge for a full refill plus a “leak repair.” In reality, air conditioning systems are sealed; gas does not evaporate. We only recommend a refill if there is a proven, detectable leak.
Red Flags:
- “Chemical fee” charged separately from the service price
- “Assessment fee” demanded before quoting a final number
- “Drainage clearing” listed as a paid add-on
- Pressure to change working capacitors “just in case”
Questions to Ask:
- Is the gas top-up included in the quoted price?
- Do you use acid-based or alkaline-based chemical cleaners? (Alkaline is safer for your coils)
- What specific warranty do you offer on water leaking after service?
- Does the price change if the unit is very dirty?
Multi-Unit Discounts
Most providers offer discounts for multiple units:
| Units | Typical Discount |
|---|---|
| 2 units | 5-10% off |
| 3 units | 10-15% off |
| 4+ units | 15-20% off |
AC Service Pro Pricing:
- 1 unit: RM120
- 2 units: RM110 each
- 3+ units: RM100 each
Is Cheap Chemical Wash Worth It?
Short answer: No.
Here’s why:
Cheap chemical wash often means:
- Diluted chemical solutions that fail to kill mold roots
- Skipped steps (like ignoring the back drainage tray)
- Rushed jobs that leave moisture on the circuit board
- No support when the unit starts leaking two days later
The result:
- Mold grows back within weeks
- Corroded coils from improper rinsing
- You pay a second technician to fix the first job
Investing in proper service:
- Lasts 6-12 months
- Restores airflow to factory standards
- Prevents “jelly” buildup in the drainage pipe
- Protects your warranty
When to Invest in Chemical Wash
Chemical wash pays for itself through:
- Lower electricity bills: A dirty AC works harder, potentially pushing your usage into TNB’s higher tariff blocks (over 600kWh).
- Avoided repairs: Clean coils reduce strain on the compressor, preventing expensive overheating issues.
- Extended lifespan: Regular maintenance removes corrosive grime that eats away at copper pipes.
- Better health: Removing mold spores improves indoor air quality for your family.
