Pricing transparency is often the biggest hurdle homeowners face when booking aircond services in Petaling Jaya. You see a low starting price online, but the final bill tells a different story once the technician adds “necessary” extras.
Hidden charges for gas top-ups, travel fees, and “difficult access” are unfortunately common in the Klang Valley. These surprises can easily double your expected cost.
At PJ Kool Aircond Service, we operate differently because we believe you should know the exact figure before you book. Our team provides upfront, all-inclusive quotes. This guide details our complete 2026 pricing for aircond chemical wash services in Petaling Jaya.
Wall-Mounted Unit Chemical Wash Prices
Wall-mounted split units are the standard for residential cooling in Malaysia, especially models from Daikin, Panasonic, and York. Keeping these units clean is critical because a clogged filter can increase energy consumption by up to 15% according to recent energy efficiency studies.
Here is the breakdown of our chemical wash costs based on horsepower:
| Unit Size | Chemical Wash Price | Free Gas Top-Up |
|---|---|---|
| 1.0HP to 1.5HP | RM160 | Included |
| 2.0HP to 2.5HP | RM190 | Included |
| 3.0HP | RM210 | Included |
These prices cover the entire cleaning process.
You receive canvas wrapping, chemical application, high-pressure flushing, blower fan cleaning, drainage clearing, and a free gas top-up. We ensure your unit runs efficiently to help you manage your Tenaga Nasional Berhad (TNB) electricity bills.
Ceiling Cassette and Ducted Unit Prices
Ceiling cassette units are frequently installed in commercial lots in SS2 or larger semi-D homes in Damansara. These systems rely on internal drainage pumps rather than gravity, which makes them more prone to water leakage if “bio-slime” blocks the pipes.
Because of their complexity and ceiling position, they require more technical expertise to service safely.
| Unit Size | Chemical Wash Price | Free Gas Top-Up |
|---|---|---|
| 2.0HP to 3.0HP | RM280 | Included |
| 3.5HP to 4.0HP | RM350 | Included |
| 5.0HP to 6.0HP | RM400 | Included |
Ducted systems and centralised air conditioning require a site visit for an accurate quote. Contact us for a custom assessment based on your specific duct configuration.
What Is Included at Every Price Point
We adhere to a strict 8-step protocol for every job to ensure quality and safety. This process applies whether you have a small bedroom unit or a large commercial cassette.
The 8-Step Cleaning Protocol
- Pre-service inspection: We test the unit’s current airflow and cooling performance to identify pre-existing faults.
- Canvas wrapping: Technicians install a waterproof canvas bag around the indoor unit to protect your walls and furniture from splashes.
- Chemical coil cleaning: An alkaline-based solution is applied to break down stubborn grease and mould without corroding the delicate aluminum fins.
- High-pressure water flush: This step blasts away the dissolved grime from the evaporator coil and drain tray.
- Blower fan cleaning: We remove heavy dust buildup from the blower barrel, which is the primary cause of weak airflow.
- Drainage pipe clearing: High-pressure water clears the drain line to prevent the jelly-like algae buildup that causes leaking.
- Free gas top-up: Technicians check refrigerant pressure (PSI) and top it up to manufacturer specifications.
- Post-service test: A final check ensures the unit blows cold air and the swing mechanism works correctly.
The only variable in our pricing is the size and type of the unit. Larger units simply require more time and a higher volume of chemical solution.
The Value of Free Gas Top-Up
This inclusion sets PJ Kool’s pricing apart from the standard market practice in Petaling Jaya. Gas top-ups are necessary when pressure drops, yet many competitors treat this as an expensive add-on.
Most aircond service companies in the Klang Valley charge significant fees for refrigerant:
| Service | Typical Market Price |
|---|---|
| R410A gas top-up (wall unit) | RM80 to RM120 |
| R32 gas top-up (wall unit) | RM100 to RM150 |
| R22 gas top-up (older units) | RM80 to RM100 |
R32 gas, which is standard in newer units for its lower environmental impact, has seen price fluctuations recently. By including this in our flat rate, we protect you from variable costs.
A RM160 chemical wash with us is often cheaper than a competitor’s RM120 base rate once you add their RM100 gas charge.
Factors That Can Affect Your Final Price
Our published prices are fixed for standard chemical washing. However, specific situations may require different approaches or additional labour. We always discuss these variables with you transparently before starting any work.
Multiple Units Discount
Servicing three or more units in a single visit allows us to optimize our travel and setup time. We pass these operational savings directly to you. Ask about our multi-unit packages if you are cleaning the whole house.
Severely Neglected Units (Chemical Overhaul)
Units that have not been serviced for over two years often suffer from deep internal clogging that a standard wash cannot reach. In these cases, a “Chemical Overhaul” is required.
This process involves:
- Pumping down the refrigerant gas.
- Dismantling the entire indoor unit from the wall.
- Soaking individual components in a chemical bath.
An overhaul is more labour-intensive and priced separately. We will only recommend this if the standard wash will not solve your airflow or cooling issues.
Access Difficulties
Most units are installed in accessible locations. However, units placed above immovable heavy wardrobes, in stairwells requiring high ladders, or inside cramped ceiling voids may incur a small surcharge. This fee covers the extra time and safety equipment needed to access the unit without damaging your property.
How PJ Kool Compares to Competitors
Smart homeowners should compare quotes to ensure they get the best value. Here is a direct comparison of our all-inclusive model versus the typical itemised billing found elsewhere in Petaling Jaya:
| Service Item | PJ Kool | Typical Competitor |
|---|---|---|
| Chemical wash (1.5HP wall) | RM160 | RM100-150 |
| Gas top-up | Free (included) | RM80-150 extra |
| Travel/transport fee | Free | RM20-50 |
| Inspection fee | Free | RM30-50 |
| Total | RM160 | RM230-400 |
The price you see on our website is the price you pay at the end of the service. You avoid the stress of negotiating with a technician in your living room.
How to Avoid Hidden Charges from Other Companies
If you decide to shop around, you must ask specific questions to protect your wallet. Unscrupulous providers often omit details to make their base price look attractive.
Essential Questions to Ask
- Does the price include gas top-up? Always verify this first. If not, ask for the specific cost per PSI for R32 or R410A gas.
- Is there a transport or call-out fee? Some companies add RM30 to RM50 just for arriving at your doorstep in areas like Ara Damansara or Kelana Jaya.
- What exactly is included in the service? Ensure the quote covers blower fan cleaning and drainage flushing. Cleaning only the filters and cover is not a chemical wash.
- Is there a warranty on water leakage? A reputable service should offer at least a 30-day warranty on workmanship, specifically regarding water leaks after service.
- Is the quote per unit or for the whole job? Clarify if the price is for a single unit or a package to avoid misunderstandings upon payment.
Clear answers indicate a professional company. Vagueness or “it depends” responses are usually red flags for hidden costs waiting to happen.
