Hong Kong is densely populated

Any model or style of air conditioner will cause dust and dirt to accumulate inside and outside the air conditioner after a period of use, which will block the air outlet or drain, resulting in the air conditioner’s cold and hot air system not being able to perform at its maximum efficiency, and even causing the air conditioner to generate Water accumulation and bad smell. This will not only increase energy consumption and electricity bills, but more seriously affect the air quality of the home, causing bacteria to grow and affecting the health of the family.

FAQ

Frequently Asked

Can't find the service you need? Feel free to call or email us

My air conditioner is leaking water. Can this be fixed during the cleaning?

We have encountered many cases of air conditioners leaking water. The leakage is usually caused by a clogged drainage pipe. During the cleaning process, we use a high-pressure water jet to clear the blockage in the drainage pipe, followed by cleaning with specialized chemicals, which can effectively resolve the water leakage issue

Do window units need to be removed for cleaning?

Generally, if the environment permits, we prefer to remove the window unit for cleaning. This allows us to thoroughly clean all parts and components of the air conditioner. However, if the environment does not allow it, or if the unit is already damaged, we will avoid dismantling the unit

If the air conditioner isn't cooling enough, does it always mean the refrigerant needs to be replaced?

As long as the air conditioner is working properly, the refrigerant circulates within the system and does not need to be refilled. If refilling is required, we first ensure that the cooling unit's location is accessible and there is enough space for the work. For typical residential settings, the condenser is usually placed on the building's exterior wall, and scaffolding may be needed to complete the job

How long does it usually take to clean an air conditioner?

If the surrounding environment is normal, the entire process—from preparation, protection, and dismantling to high-pressure cleaning, followed by cleaning with specialized chemicals, reassembly, and final post-cleaning—typically takes around 45 to 60 minutes

What payment methods do you accept?

Air conditioning repair fees are to be paid in cash, and payment will be collected on-site upon completion of the service.

What should I do if there is an issue with the air conditioner after cleaning?

Each service comes with a 30-day post-service warranty. If any issues or malfunctions occur after the air conditioner cleaning, the cost of the repair includes after-sales service. We will provide free maintenance, so you can rest assured.

Customer Reviews

The dripping problem with my home air conditioner has been bothering me for years! I was originally thinking of just replacing it… but then I saw your company’s service on Facebook, so I decided to give it a try! To my surprise, it was truly a pleasant experience! Master Lai is very nice, and the cleaning was thorough and professional! He explained the causes of mold in the air conditioner and the sources of dust, and also analyzed and solved the issue of the unit’s installation angle. He even gave me tips on future maintenance! From now on, my air conditioner will rely on you! I’ll definitely recommend your service to my friends
