Aircond Chemical Wash Price in Malaysia (2026 Guide)

One of the most frequent concerns homeowners in PJ and KL share with us is the confusion surrounding aircond service rates.

You see a banner for RM60 on a lamp post, but then you get a quote for RM150 from a reputable company.

We understand how frustrating this price disparity feels.

The reality is that “chemical wash” has become a loose term in 2026, covering everything from a quick spray to a full dismantle.

We are going to break down exactly what you should pay, why the prices vary, and how to spot a quote that is too good to be true.

This guide provides the transparency you need to make the right choice for your home.

Average Chemical Wash Prices in Malaysia (2026)

Market rates have adjusted slightly this year due to rising labour and material costs.

We have compiled the current standard rates for a proper, deep-clean chemical wash in the Klang Valley.

These figures reflect professional services that use safe chemicals and proper drainage methods.

Unit Type	Price Range (per unit)	Best For
Wall-mounted (1.0 - 1.5 HP)	RM100 - RM160	Standard bedrooms
Wall-mounted (2.0 - 2.5 HP)	RM130 - RM200	Living rooms / Master bedrooms
Cassette (ceiling-mounted)	RM180 - RM280	Offices, cafes, retail shops
Ceiling concealed / ducted	RM250 - RM400	Luxury condos, commercial sites
Floor standing	RM200 - RM300	Event halls, large showrooms

Be aware that these ranges cover the labour and chemicals for a standard service.

The “Overhaul” vs. “Wash” Distinction

A major point of confusion for customers is the difference between a general chemical wash and a chemical overhaul.

We find that many competitors use these terms interchangeably, but they are very different procedures.

1. General Chemical Wash (Canvas Method): The technician places a bag (canvas) around the unit and uses a high-pressure jet with chemicals. The unit stays on the wall.
2. Chemical Overhaul (Dismantle): The technician pumps down the gas, removes the entire unit from the wall, and takes it apart to clean every individual component.

An overhaul typically costs RM50 to RM100 more than the standard wash prices listed above.

Always ask the technician which method they are quoting for before they arrive.

Multi-Unit Discounts

Servicing a single unit often incurs a minimum trip charge effectively built into the price.

We always recommend grouping your service requests to lower the cost per unit.

This efficiency saves our technicians travel time, and we pass those savings back to you.

Number of Units	Typical Savings	Strategy
2 units	RM10 - RM20 off total	Service the master bedroom and living room together
3-4 units	10-15% discount	Full home service (most popular for condos)
5+ units	15-20% discount	Combine orders with a neighbour

At PJ Kool, we offer competitive multi-unit packages for homes and offices across the Klang Valley. Our prices include the gas top-up that other companies charge separately.

What Affects the Price of a Chemical Wash?

The final bill depends on more than just the type of air conditioner you own.

Technicians consider five specific variables when calculating a fair quote.

1. Refrigerant Gas Type (R22 vs. R32/R410A)

Newer air conditioners typically use R32 or R410A gas, which is standard and readily available.

Older units (10+ years) often run on R22 gas, which is being phased out globally and has become significantly more expensive.

We have to charge more for R22 top-ups simply because the supply is scarce and the cost price is high.

2. Inverter vs. Non-Inverter Technology

Inverter units are excellent for energy saving, but they contain sensitive electronic boards that are easily damaged by water.

Technicians must take extra precautions to wrap and protect these circuit boards during a chemical wash.

This additional care and risk management can sometimes add a small premium to the service cost.

3. Accessibility and Height

A standard ladder reaches up to 10 feet, which covers most residential installs.

Units installed above stairwells, on double-volume ceilings, or requiring scaffolding present a safety risk.

We may need two technicians for these jobs—one to stabilize the ladder and one to clean—which naturally increases the labour cost.

4. Level of Contamination (The “Jelly” Factor)

Neglected units often develop a thick, jelly-like biofilm in the drainage pan.

Clearing this blockage requires repeated flushing and stronger chemical applications to prevent immediate leaking after service.

Extremely dirty units may require a full dismantle (overhaul) rather than a standard wash to truly solve the problem.

5. What’s Included in the Service

This is where pricing gets tricky. A “chemical wash” from one company might not include the same things as another. Always confirm:

• Is the gas top-up included or charged separately?
• Does the service include drainage pipe clearing?
• Is there a call-out or transport fee?
• Are there surcharges for weekends or public holidays?

At PJ Kool, our chemical wash price includes gas top-up, drainage clearing, and a full inspection — no hidden fees.

Price Comparison: PJ Kool vs Industry Average

Many low-cost advertisements rely on “bait and switch” tactics where the base price is low, but necessary add-ons inflate the final bill.

We believe in a single, transparent price that covers the job from start to finish.

Service Item	Industry Average	PJ Kool Approach
Base Chemical Wash	RM80 - RM120	RM120 - RM150 (All-in)
Gas Top-Up (up to 20psi)	RM50 - RM80 extra	Included (Free)
Drainage Flushing	RM30 - RM50 extra	Included (Free)
Transport Fee	RM30 - RM50	Waived for PJ/KL areas
Warranty on Leaking	7 Days (or none)	30 Days
TOTAL ESTIMATED COST	RM190 - RM300	RM120 - RM150

When you factor in all the extras that competitors charge, PJ Kool’s all-inclusive pricing often works out cheaper than the “cheap” services advertised online.

Red Flags: When the Price Seems Too Good

You should be cautious of chemical wash services priced below RM80 per unit in 2026.

Operating costs for transport, quality chemicals, and skilled labour make it impossible to offer a genuine service at that price point.

We often see three common issues with “budget” providers:

• The “Acid” Short-Cut: Unscrupulous technicians use harsh industrial acid instead of proper coil cleaner. This cleans the unit instantly but corrodes the copper coils, leading to gas leaks within 6 months.
• The Gas Leak Hoax: The technician claims your gas is empty and charges RM150 to refill it. Fact check: Aircond gas is a closed loop system; if it needs refilling, there is a leak that must be fixed first.
• The 15-Minute Wash: A proper chemical wash takes 45 to 60 minutes per unit. If they are done in 15 minutes, they likely only brushed the filters.

A genuine chemical wash requires professional-grade chemical solutions, proper equipment, and skilled labour. There’s a baseline cost that legitimate companies can’t go below.

How to Get the Best Value for Your Money

Here are our tips for getting quality aircond service at a fair price in the Klang Valley:

1. Ask for all-inclusive pricing — confirm gas top-up and extras are included
2. Service multiple units together — you’ll get a better per-unit rate
3. Book during weekdays — some companies charge more on weekends
4. Choose a company with transparent pricing — no surprises when the bill comes
5. Don’t chase the lowest price — focus on value, not just cost
6. Schedule regular maintenance — preventive care is always cheaper than emergency repairs
