Free Smart Diagnosis
Is your aircond cooling properly? Water leaking? Bad smell? Noisy? Weak airflow? Answer a few quick questions and this tool tells you whether you need a basic service, chemical wash, chemical overhaul, gas top-up, repair or inspection — with the reason for each recommendation and the published starting price.

Alat Diagnostik Masalah Aircond | 冷气问题诊断工具
What is the main problem with your aircond?
Apakah masalah utama aircond anda? | 您的冷气主要出现什么问题？
Choose the main problem you are experiencing — not cold, water leaking, noise, bad smell, weak airflow, not turning on, tripping MCB, ice formation or remote issues.
Answer one or two follow-up questions about severity and timing — e.g. did cooling stop suddenly or gradually, is the leak a drip or continuous flow.
The tool matches your answers against common HVAC failure patterns and recommends the correct service: basic servicing (from RM 99), chemical wash (from RM 120), chemical overhaul (Wall-Mounted Aircon only, from RM 420), gas top-up (from RM 2.50/PSI), repair (diagnostic RM 88, waived with repair).
Each recommendation explains WHY it was made — the likely cause, the fix and how urgent it is.
Send the diagnosis to KL Renovator on WhatsApp with one tap, or read the full problem guide linked in the result.
A technician confirms the diagnosis on-site and gives you a fixed price before any work begins.
Filter cleaning and multi-point check. Right for routine 3–6 month maintenance when the unit cools fine, no smells, no leaks.
High-pressure internal coil cleaning. Right for weak airflow, musty smell, gradual cooling loss, or units not serviced in 12+ months.
Full dismantle and deep clean of the wall-mounted indoor unit. Right for water leaking, ice formation, severe blockage — the permanent fix for drain problems. Ceiling cassette, ducted, floor-standing, portable, window and other non-wall-mounted aircon types require a separate on-site quote.
Precision refrigerant balancing with leak check. Right when cooling drops gradually over weeks or the outdoor unit runs but air stays warm.
Component faults: capacitor, fan motor, PCB, sensor. Right for sudden failure, loud noise from the outdoor unit, or error codes. Diagnostic fee is waived if repaired same visit.
When the problem is unclear or a unit has been untouched for years, an inspection gives a written quote for everything needed — no pressure to proceed.
Definitions
Short, plain-language definitions of the terms used above — written by the technicians who do the work, not copied from a manufacturer brochure.
A pressure chemical wash is a deep clean done with the indoor unit still on the wall. The technician sheets the wall and floor, sprays a coil-safe chemical onto the evaporator fins and blower wheel, then flushes everything out with a pressurised water jet into a catch bag. It removes the mould film and dust mat that ordinary filter washing cannot reach. Published price starts at RM 120 for a 1.0–1.5 HP wall unit.
Most Klang Valley homes need one every 10–12 months; every 6 months if the unit runs overnight or the room faces a construction site.
Basic servicing is the maintenance visit: filters washed, front panel and louvres wiped, drain path flushed, outdoor coil brushed, and cooling temperature plus running current checked before the technician leaves. It keeps airflow and efficiency stable but does not strip mould off the coil. Published price starts at RM 99 per 1.0–1.5 HP unit.
Every 3–4 months is the realistic interval for a bedroom unit in KL; stretch it and the next chemical wash gets harder, not cheaper.
A chemical overhaul is the level above a chemical wash: the indoor unit is dismounted, dismantled into casing, blower wheel, drain tray and coil, and each part is soaked and scrubbed separately before reassembly and a leak test. It is the only way to clear a drain tray that has silted up or a blower wheel packed solid with mould. Published price starts at RM 420 for 1.0–1.5 HP.
Ask for an overhaul instead of another wash if the unit still drips or smells within weeks of a chemical wash.
Side-by-side comparison
Both are cleaning visits, but they clean different parts of the unit and are not interchangeable.
| What to compare | Pressure chemical wash | Basic servicing |
|---|---|---|
| What gets cleaned | Coil, blower wheel, drain tray, filters | Filters, panel, drain flush, outdoor coil brush-down |
| Fixes smell and weak airflow | Yes — that is the point of it | Only if the filter was the blockage |
| Time on site | 45–90 minutes per unit | 20–30 minutes per unit |
| Published price (1.0–1.5 HP) | RM 120 | RM 99 |
In short: Book basic servicing on a 3–4 month rhythm; book a chemical wash when the smell, the airflow or the water dripping tells you the coil itself is loaded.
Chemical wash (RM 120+) cleans the coil in place — right for weak cooling, smells and slow airflow. Chemical overhaul (RM 420+) fully removes and dismantles the indoor unit — right when water is leaking, ice forms, or the unit has not been deep-cleaned in 2+ years. As a rule: wash for performance, overhaul for leaks and ice.
Basic servicing every 3–6 months, and a pressure chemical wash every 12 months — or every 6–8 months if the unit runs 8+ hours a day. Units near busy roads or construction sites need more frequent cleaning due to dust.
This is most often low refrigerant gas or a failing capacitor. Book a diagnostic (RM 88, waived if repaired same visit) or a gas top-up with leak check. KL Renovator measures the pressure with a manifold gauge and confirms the cause on-site.
A musty smell means mould, bacteria and biofilm have built up on the evaporator coil and blower wheel — very common in KL's humidity. A pressure chemical wash (from RM 120) dissolves the biofilm and restores clean airflow. If the smell persists after washing, an overhaul may be needed.
Basic service from RM 99, pressure chemical wash from RM 120 (1.0–1.5 HP wall-mounted), chemical overhaul from RM 420, gas top-up from RM 2.50/PSI (R22) or RM 3.00/PSI (R410A/R32). Ceiling cassette and commercial units are priced separately. Every price is confirmed before work begins.
