Four key points when choosing a service
Charges and scope explained before booking
Quotation will be based on published pricing and on-site conditions. Please specify the service items and applicable surcharges before booking; if extra work is needed, the scope and fees will be explained first
Clean by model, not just the casing
Arrange cleaning according to the structure of window units, split units and commercial air conditioners, addressing internal dirt and checking drainage. Explain the work steps before cleaning, and confirm the dismantling method and service scope according to the model and on-site conditions.
Protected during work, checked upon completion
Before cleaning, inspect the unit condition and arrange waterproof protection. After cleaning, provide before-and-after comparison photos, clean up the work area and test the unit, and explain daily maintenance to the customer. Notes
After-sales support with follow-up on issues
The cleaning service includes a 90-day warranty. Issues caused by cleaning will be handled according to the applicable terms; dripping and leakage must first have the cause verified. Not all faults are considered solvable by cleaning
Damage during cleaning guaranteed:If damage is confirmed to have been caused by our staff during the air conditioner cleaning process, our company will bear the cost
Cleaning equipment and site protection
Pressure-washing equipment is used on accessible cooling fins, fan wheels and soiled components. Wet-vacuum equipment helps collect wastewater and work around drainage points. Water pressure, nozzle position and dismantling methods must suit the unit, its components and the site; higher pressure is not necessarily better.
Before cleaning, isolate the power and arrange protective covers and wastewater collection to protect electrical components, walls, furniture and other equipment. After cleaning and reassembly, check operation and drainage.
Cleaning products and equipment models
Our previous equipment guide featured BBJ cleaning products and WORX wet-vacuum equipment. Product information is separate from the service scope: products and tools are selected for material compatibility, manufacturer instructions and site requirements. The same brand or model is not guaranteed for every visit.
Cleaning is not repair, medical-grade disinfection or a guarantee of complete stain removal. Some oil contamination, corrosion and faults cannot be resolved with more pressure or detergent. Electrical work and internal dismantling should be arranged with suitably qualified personnel.
SERVICE PROCESS
From preparation to cleaning completion
Learn about each service step

Cleaning procedures and service scope vary by model and site conditions.
Common questions before choosing
When choosing an AC cleaning company, what should you look at besides price?
You should also understand the cleaning scope, the procedures arranged by model, water protection, post-cleaning checks, and after-sales follow-up terms. OPOExpert Air Conditioning provides public pricing, actual work records, and excerpts of customer messages, so service details can be checked before booking.
If the air conditioner is not cold enough or is dripping water, will cleaning always solve it?
Not necessarily. Dust buildup or blocked drainage may require cleaning, but refrigerant leakage, parts failure or circuit faults may require repair. The decision should be made based on the actual condition; cleaning should not be treated as the solution to every fault. You may first enquire with the model, symptoms and site photos.
Can household and commercial air conditioners use the same cleaning arrangement?
Both must be confirmed according to the model, quantity, and work location. Home window-type units and split-type units have corresponding cleaning procedures; commercial units in offices, shops, or restaurants require separate confirmation of system structure, working height, drainage, and site conditions, and home rates and procedures cannot be applied directly.
If there is a problem after cleaning, how does the 90-day warranty and damage compensation apply?
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. If damage is confirmed to have been caused by our staff during the air conditioner cleaning process, the company will bear the cost. You may contact customer service with the service date, issue details and photos to verify the records and follow-up method.
