Aircond Service Brands
Yes — KL Renovator services all Mitsubishi aircond models across KL & Selangor. KL Renovator services all Mitsubishi aircond models across KL and Selangor — including the MSY Series, MXY Multi-Split and Mr Slim ceiling cassette systems. Chemical wash, gas top-up, PCB repair and Mitsubishi installation handled by certified technicians.
Model: Mitsubishi MSY Series, Mitsubishi MXY Multi-Split, Mitsubishi MFZ Floor Standing, Mitsubishi Mr Slim Ceiling Cassette.
Mitsubishi's MSY Series (wall-mounted) and most current MXY multi-split systems are inverter-based, meaning the compressor runs continuously at variable speed rather than switching fully on/off. This is gentler on the compressor and gives more stable room temperature, but it also means inverter Mitsubishi units should never be serviced with the power still connected — our technicians always isolate power at the MCB before opening any inverter unit.
A humming but non-draining condensate pump on Mr Slim cassette units is usually a clogged drain hose, not a failed pump motor. We flush the drain line first — replacing the pump is a last resort and rarely needed if flushed within the first year of the symptom.
Loud vibration (not just fan noise) from an MSY outdoor unit usually means the rubber mounting feet have degraded or the unit is no longer level on its bracket — a 10-minute bracket check often resolves this without any part replacement.
This is almost always an accidentally-set sleep or timer schedule left active from a previous user, not a fault. We check and clear the timer memory as part of every basic service call.
KL Renovator is an independent HVAC service company, not an official agent or authorised service centre of Mitsubishi. We service, repair and install Mitsubishi units using genuine or OEM-equivalent parts (capacitors, PCB boards, gas, drain pumps) from trusted Malaysian suppliers — never counterfeit or unverified parts. If yourMitsubishi unit is still under manufacturer warranty, we will tell you first whether the repair may affect that warranty, so you can choose to go to the official Mitsubishi service centre yourself if needed. Our job is honest, transparent service — not selling a unit you do not need.

Aircond service for Mitsubishi means a technician checks cooling performance, airflow, drainage, electrical safety and visible wear before recommending basic cleaning, chemical wash, troubleshooting or replacement. The goal is to solve the actual fault without selling unnecessary work.
| Service option | Published price | Best for |
|---|---|---|
| Pressure chemical wash | RM 120 | For Mitsubishi: weak airflow, odour, dusty blower wheel or indoor coil grime |
| Chemical overhaul | RM 420 | For Mitsubishi: severe blockage or water leaking after normal servicing |
| Diagnostic / troubleshooting | RM 88 | For Mitsubishi: unknown fault, tripping, blinking light or noisy outdoor unit |
| New wall-mounted installation | RM 199 | For Mitsubishi: replacing an old unit or fitting a new room |
| Basic service / cleaning | RM 99 | For Mitsubishi: routine maintenance when cooling is still acceptable |
Gas top-up is charged by refrigerant: R22 RM 2.50 / PSI, R410A RM 3.00 / PSI, R32 RM 3.00 / PSI. Extra copper pipe, wiring or access work follows the published material list.

Yes — KL Renovator services Mitsubishi Mr Slim ceiling cassette and MXY multi-split systems in offices, shops and commercial buildings across KL and Selangor.
Mitsubishi P8 indicates an outdoor unit protection fault (often low gas or compressor issue). E6 is a communication error. KL Renovator reads all Mitsubishi error codes.
Most new Mitsubishi models use R32. Some older models use R410A. KL Renovator identifies the correct refrigerant from your model number before topping up.
Uneven cooling on MXY multi-split systems is usually one indoor unit with a dirty filter or coil restricting its airflow, not a system-wide gas issue — since all indoor units share one outdoor compressor, a single blocked unit can seem like 'weak' cooling everywhere. We check each indoor head individually.
Yes — the MXY Multi-Split and Mr Slim ceiling cassette range are commonly used in shoplots and small offices because one outdoor condenser can serve multiple indoor units, saving external wall/roof space. KL Renovator services these commercial setups regularly.
A standard Mitsubishi wall-mounted chemical wash takes 45-60 minutes. Ceiling cassette units or heavily neglected systems may require up to 90 minutes for a thorough deep clean.
Yes. We use genuine or high-quality OEM-equivalent components (capacitors, sensors, PCB boards) for all Mitsubishi units to ensure compatibility and system longevity.
