What Is the Difference Between Chemical Wash and Chemical Overhaul?
Understanding the difference is important because it directly affects the price.
Standard Chemical Wash: The technician sprays chemical cleaning solution onto the evaporator coil, blower fan, and drainage components while they remain in place. The unit is partially disassembled (front panel and filters removed) but the main components stay mounted on the wall. This is faster and more affordable.
Chemical Overhaul: The technician fully disassembles the indoor unit. The evaporator coil, blower fan, drain pan, and other components are removed from the wall bracket and soaked in chemical solution. Each part is cleaned individually and thoroughly before reassembly. This is more time-consuming but delivers the deepest possible clean.
For most residential units that receive regular maintenance, a standard chemical wash is sufficient. A chemical overhaul is recommended for severely neglected units or those that are more than 5 years old and have never had a deep clean.
What Affects the Price?
Several factors influence the final cost of your chemical wash:
1. Unit Type and Size
Larger units with higher horsepower ratings cost more because they have bigger coils, larger blower fans, and require more chemical solution. Ceiling cassette units are also more expensive to service because they require more labour to access.
2. Accessibility
If your indoor unit is installed in a hard-to-reach location, such as above a wardrobe, in a high-ceiling area, or behind furniture that needs to be moved, technicians may charge extra for the additional labour and time required.
3. Condition of the Unit
A severely dirty unit that has not been serviced in years will take longer to clean. Some companies charge a premium for units in exceptionally poor condition because they require additional soaking time and chemical solution.
4. Number of Units
Most companies offer discounts when you service multiple units at once. This is because the technician is already at your location with all the necessary equipment. Common multi-unit discounts in PJ:
| Number of Units | Typical Discount |
|---|---|
| 2 units | 5-10% off total |
| 3-4 units | 10-15% off total |
| 5+ units | 15-20% off total |
5. Brand of Aircond
While most technicians charge the same regardless of brand, some premium brands like Daikin or Mitsubishi Heavy Industries units with complex designs may cost slightly more due to the additional time needed for disassembly.
Red Flags in Pricing
When comparing quotes from different aircond companies in Petaling Jaya, watch out for these warning signs:
Prices that are too low: If someone quotes you RM60 to RM80 for a chemical wash, be suspicious. At that price, they are likely just doing a standard cleaning and calling it a chemical wash. Genuine chemical cleaning solutions cost money, and the labour involved takes at least an hour per unit.
No upfront pricing: Reputable companies will give you a clear price before the technician arrives. If a company refuses to quote over the phone or says “we need to see first,” they may be planning to upsell you on-site.
“Free inspection” that leads to expensive repairs: Some companies offer free inspections as a way to get into your home, then pressure you into unnecessary repairs like gas top-ups or part replacements.
Hidden charges: Always ask whether the quoted price includes everything. Common add-on charges include transportation fees, materials fees, or charges for washing the outdoor unit.
How to Get the Best Value
Bundle Your Services
If you have multiple aircond units, schedule them all for the same visit. You will save on per-unit costs and the technician can work more efficiently.
Sign Up for a Maintenance Package
Many aircond companies, including PJ Kool Aircond Service, offer annual maintenance packages that include standard cleanings and chemical washes at a bundled rate. These packages typically save you 15-25% compared to booking each service individually.
Do Not Skip Standard Cleanings
Regular standard cleaning every 3-4 months (at RM50-RM80) keeps your unit in better condition, which means the chemical wash goes faster and is less likely to require the more expensive overhaul treatment.
Ask About the Chemicals Used
Quality matters. Professional-grade aircond chemical solutions are pH-balanced and designed specifically for aluminium fins and copper coils. Cheaper alternatives can corrode components over time. It is worth paying a bit more for a company that uses proper cleaning agents.
Is It Worth the Money?
Absolutely. Consider the maths:
- Annual chemical wash: RM150 to RM200
- Electricity savings from a clean unit: RM20 to RM50 per month (RM240 to RM600 per year)
- Extended lifespan: A well-maintained unit lasts 12-15 years versus 6-8 years for a neglected one
- Compressor replacement (if neglected): RM800 to RM2,000
- New unit (if the old one dies prematurely): RM2,000 to RM5,000
A yearly investment of RM200 in chemical washing can save you thousands in the long run while keeping your electricity bills lower and your indoor air quality healthier.
