Professional Aircond Chemical Wash — FREE Gas Top-Up Included

Aircond Chemical Wash in Petaling Jaya

Is your air conditioner not cooling as well as it used to? Are you noticing a musty smell every time the unit turns on, or water dripping from the indoor unit? These are all signs that your aircond needs more than a basic wipe-down. A professional aircond chemical wash is the most effective way to restore your unit to peak performance, and at PJ Kool Aircond Service, it is our most requested service for good reason.

Why Chemical Wash Is Essential for Malaysian Homes

Malaysia’s tropical climate means your air conditioner works harder than units in cooler countries. The combination of high humidity, dust, and constant operation creates the perfect environment for mould, bacteria, and grime to accumulate deep inside your aircond. Over time, this buildup coats the evaporator coils, clogs the drainage pipe, and forces the compressor to work overtime just to maintain a comfortable temperature.

A chemical wash addresses all of these problems in a single service visit. By fully dismantling the indoor unit and applying an industrial-grade chemical solution, we dissolve stubborn deposits that regular cleaning simply cannot reach. The result is noticeably colder air, lower electricity bills, and a healthier indoor environment for your family.

What Happens During a Chemical Wash

When our technician arrives at your home in Petaling Jaya, the first step is always a thorough inspection. We check the current cooling output, listen for unusual sounds, and examine the drainage for any signs of blockage. This initial assessment helps us identify any underlying issues beyond routine maintenance.

Next comes the full dismantle. Unlike a standard cleaning where only the filters and front cover are removed, a chemical wash requires us to take apart the entire indoor unit. The front panel, air filters, blower wheel, fan barrel, and drainage tray are all carefully removed and set aside. This gives us unrestricted access to the evaporator coils, which is where the majority of dirt and biological growth accumulates.

We then apply a professional-grade alkaline chemical cleaning solution directly to the coils. This solution is specifically formulated to break down grease, dissolite mineral deposits, kill mould spores, and eliminate bacteria without damaging the delicate aluminium fins of the evaporator. The chemical is left to soak and react before being thoroughly rinsed away with clean water.

While the coils are being treated, the drainage pipe receives a high-pressure flush. Blocked drainage is the number one cause of water leaking from aircond units in Petaling Jaya homes, and this step ensures the condensate can flow freely. The blower wheel and other dismantled components are also individually cleaned and dried.

Once everything is spotless, we reassemble the unit with care. The refrigerant gas pressure is measured, and a FREE top-up of up to 10 psi is included at no additional charge. Finally, we run the aircond and measure the output temperature to confirm it is performing at the correct level. Most customers notice an immediate difference in cooling power.

Pricing That Makes Sense

We believe in transparent, upfront pricing with no hidden fees. Our chemical wash rates are based solely on your aircond’s horsepower rating:

• 1.0 to 1.5 HP: RM 160 per unit
• 2.0 to 2.5 HP: RM 190 per unit
• 3.0 HP: RM 210 per unit

Every tier includes the same comprehensive service: full dismantle, chemical coil wash, drainage flush, component cleaning, and FREE gas top-up. There are no surprise charges at the end of the job.

For customers with multiple units, we offer attractive package discounts. Many homeowners in Petaling Jaya have three to five aircond units across bedrooms and living areas, and servicing them together saves both time and money. Contact us for a custom quotation if you have more than one unit to service.

Signs Your Aircond Needs a Chemical Wash

Not sure whether your unit needs attention? Here are the most common indicators that it is time to book a chemical wash:

Reduced cooling performance is the most obvious sign. If your aircond is running but the room does not feel as cold as it used to, dirty coils are almost certainly the culprit. The layer of grime acts as insulation, preventing the refrigerant from absorbing heat effectively.

Unpleasant odours when the unit starts up indicate mould or bacterial growth inside the unit. This is not just a comfort issue but a health concern, especially for household members with allergies or respiratory conditions.

Water leaking from the indoor unit typically means the drainage pipe is partially or fully blocked. Left unattended, this can cause water damage to walls and ceilings.

Higher electricity bills without a change in usage patterns suggest your aircond is working harder than it should. A clean unit operates more efficiently, which translates directly into energy savings on your monthly Tenaga Nasional bill.

Unusual noises such as rattling or gurgling can indicate loose components or trapped debris within the unit. A full dismantle during chemical wash allows us to identify and address these issues.
