SERVICE DETAILS
Mitsubishi Electric AC cleaning,Repair, Installation and Inspection
Mitsubishi Electric and Mitsubishi Heavy Industries are different brands. When enquiring, please send a photo of the unit model label, so you do not only write "Mitsubishi" and select the wrong equipment details, operating instructions or repair direction.
OVERVIEW
Overview
Mitsubishi Electric AC cleaning, fault inspection, repair and installation arrangements. Mitsubishi Electric AC cleaning first confirms the Mitsubishi Electric unit label, then disassembles and cleans according to the actual model. Check the applicable cleaning process, current price list, inspection fee, and the scope between repair and installation.
KEY CHECKS
Key preparation points before arranging
Check the Mitsubishi Electric label
Confirm the brand from the nameplate on the unit, not just from the remote control appearance or a spoken shorthand. The model numbers of the indoor and outdoor units should be recorded separately, and data from another Mitsubishi brand should not be mixed in.
Identify motorized vanes and sensor components first
If the equipment has motorised air direction, sensors or other add-on modules, identify the dismantling and protection method according to the model before cleaning; all accessories cannot simply be rinsed with water.
Distinguish household and multi-unit systems
If one outdoor unit is connected to multiple indoor units, or the equipment is managed by the building, please state that as well. The number of units to be cleaned, shutdown and fault inspection must be confirmed according to the actual connection scope.
Charges are based on the model; no separate brand pricing.
Household and commercial air conditioning use the relevant current price lists, with additional confirmation based on quantity, unit location and extra work; brand pages do not set unconfirmed prices or maintenance commitments.
Confirm services other than cleaning first
Repairs are first inspected to confirm the cause and quotation; installation is assessed based on the new or old unit, piping, drainage, and power supply scope. Factory authorization, specific parts, and capability for all models are not implied by this page.
CLEANING FIRST
AC Cleaning Scope and Work Arrangement
For Mitsubishi Electric AC cleaning, first confirm the Mitsubishi Electric unit label, then disassemble and clean according to the actual model. For split-type indoor units, the fan drum, cooling coil and drainage are the focus. If several rooms are connected to the same system, first confirm the shutdown scope, and do not apply Mitsubishi Heavy Industries cleaning arrangements.
Inspect first, then clean, and finally test the unit
- First record the condition of the unit, confirm the installation location, removable parts and scope of work, and protect furniture, goods and electronic devices under the unit
- Dismantle and clean the applicable parts according to the actual model and safety conditions, handle dirt build-up, water collection and drainage, and do not treat repairs as included in washing the unit
- After reassembling the parts, test run, check drainage and tidy the site; if there is any pre-existing fault or extra work, it will be explained and quoted first

ViewCommercialAC cleaning price listCleaning maintenance and pricing90-day cleaning maintenance is subject to the terms; pricing is based on model type and number of units
The cleaning service includes a 90-day warranty for problems caused by the cleaning service; dripping and leakage cases must first have the cause verified and the applicable terms confirmed at booking, and not all cases qualify for free repair.
The following are for reference by equipment type only, and do not mean the same brand or venue must use all of the above models. Basic cleaning is priced by model and unit count; outdoor condensers, steam add-ons, special locations and extra work are subject to eligibility checks, and no brand-specific or industry-standard price is created.

FAULT INSPECTIONAir Conditioner Inspection: Identify the Problem FirstIf no repair is carried out, a fixed HK$500 inspection/attendance fee applies; it can be waived from the repair fee if you proceed with the repair.
Provide the indoor and outdoor unit model numbers separately, and explain which room is affected and whether there are any fault indicators. The appearance of the remote control or the abbreviation "Mitsubishi" is not enough to identify a fault; the exact brand, model and operating condition must be checked.
Inspection fee and safety reminder
After the technician visits for an inspection, if the customer does not proceed with the repair or does not accept the repair quotation, a fixed HK$500 inspection/attendance fee will be charged; this is a single charge and is not split into two separate charges.
If you notice a burning smell, smoke, repeated tripping, or water near electrical parts, stop using the equipment first. Do not keep restarting it or dismantle it yourself.
REPAIRAir conditioning repair: confirm the quotation first, then proceedProceed only after the quotation is confirmed; our repair service does not include warranty
Mitsubishi Electric repairs do not use Mitsubishi Heavy Industries fault codes or parts information. After confirming the fault location, we will check the required parts, availability and scope we can handle; where multiple connected units are involved, separate local repair from system work.
Keep costs and maintenance separate
If you agree to proceed with repairs, HK$500 can be deducted from the repair fee; please check the deduction and amount payable when confirming the quotation.
Our repair service does not include a warranty, including repair parts and workmanship. Please understand the repair scope and fees before accepting the quotation.
Repair parts must be checked against model and supply. We do not guarantee that parts are available for all models or that same-day repair is possible. We will not treat refrigerant top-up as necessary before the cause is confirmed.
INSTALLATIONAC installation and replacementGeneral installation includes a one-year warranty, separate from the manufacturer's warranty; new power supply wiring and extra works quoted separately
When replacing a Mitsubishi Electric unit, the complete indoor/outdoor unit match, piping, drainage, power supply and installation space must be checked. Do not assume compatibility just because another unit is also called "Mitsubishi". If you want to reuse the old copper pipes, brackets or control equipment, first confirm suitability.
Quote separately for work beyond the basic scope
Pulling a new power supply from the main switch to the unit is not included; please provide the existing power supply location for the technician to assess and quote separately.
First confirm old unit removal, transport, copper pipes (the copper tubes through which the refrigerant flows), drain pipes, fixing and any extra work needed. General installation warranty and the manufacturer's product warranty are separate. Please see the installation service page for the full scope; special systems are not directly subject to general replacement terms.

QUESTIONS
Frequently asked questions
Are Mitsubishi Electric and Mitsubishi Heavy Industries the same brand page?
No. The website separates enquiry entry points for the two brands, but the actual equipment is still based on the label on the unit model, and model numbers, fault codes or parts information are not mixed up.
Enquire about ThreeWhat should be provided for Mitsubishi Electric AC cleaning?
Please provide a photo of the model label, the sticker showing the brand, model and unit serial number, a photo of the entire air conditioner, the quantity, indoor and outdoor locations, and the district. If you cannot find the label, you may first send a photo of the entire unit; no need to dismantle it yourself. If there is water dripping, insufficient cooling, unusual noise or a fault code, please state that as well.
Is this page an official repair centre for Mitsubishi Electric?
This is not a statement from the original manufacturer or an authorised repair centre. This page provides service enquiry information for OPOExpert Air Conditioning. For original warranty, specified parts or specialised systems, please first confirm the applicable scope.
Are the inspection fee and the call-out fee charged twice?
After the technician visits for an inspection, if the customer does not proceed with the repair or does not accept the repair quotation, a fixed HK$500 inspection/attendance fee will be charged; this is a single charge and is not split into two separate charges. If repair is approved, HK$500 can be deducted from the repair cost; please confirm the deduction and the amount payable when confirming the quotation. Inspection does not include cleaning, parts or repair, and related work will only be arranged after the quotation is confirmed.
Is the warranty the same for repairs and installations?
Our repair service does not include a warranty, including repair parts and workmanship. Please understand the repair scope and fees before accepting the quotation. We provide a one-year installation warranty, covering brackets and leaks caused by glass sealing or sealant. For split units, it also covers refrigerant leakage caused by poor refrigerant-pipe connection; not all water leaks or refrigerant leaks are covered by installation warranty. The two services must not be mixed up; for the full scope and exclusions, please see the repair and installation service pages, and special systems must be confirmed separately.
