If you are fortunate to have a Daikin aircon in your home, you should understand how essential aircon is in Singapore, especially when the sun hits. Since an aircon keeps your home refreshingly cool, it is important to consider a Daikin aircon servicing regularly to ensure the device can operate for optimal performance.
We strongly recommend servicing your Daikin aircon with a six-month interval by a daikin professional service. However, to cut your budget low, here are some tips on what you can do to ensure your lovely Daikin aircon do not give you any problem in the long run.
Daikin air conditioning maintenance is important to ensure your Daikin aircon perform at top-notch condition and cut down your electricity bill. Below are daikin air conditioner maintenance checklist.
It is one of the important components in the Daikin air conditioner system as it helps to get rid of any harmful substance available in the air in your room. Furthermore, when the air filters are dirty, it would be difficult to purify the air even you are using the aircon throughout the day, your room may not be as fresh as it would when your air filter is still intact. Therefore, it is vital to clean the Daikin aircon filter at two weeks interval to keep it clean.
To clean the air filter, first, you will have to remove its casing. After this, remove the filter to wipe it off. Then prepare a mixture that contains water and non-abrasive cleaning agent to clean. You need to make sure the filter has dried completely before returning it to the air con. Always check the filter regularly if it needs replacement.
A good Daikin aircon servicing should include every component of your aircon. Therefore, you need to check daikin condenser unit for obstruction as it helps to convert a refrigerant a liquid to a vapor, and it must not be blocked. If there are any blockages, it should be removed immediately.
The air ducts are an essential component in an aircon to keep your house clean. However, continuous usage may lead to the accumulation of dust and debris. Hence, air ducts should not be overlooked in your Daikin aircon servicing. It would be best if you cleaned it regularly. Thus, a professional assistant is recommended to clean the ducts at least once a year.
A Daikin aircon consists of a heat exchanger popularly referred to as condenser far. It’s a specific component that helps to minimize the energy consumption when the aircon is working. This fan is located at the back of Daikin aircon units. It is important to keep the fan clean whenever you are using the aircon as it is among the aircon components that need regular care. Doing this will help prevent accumulated dirt from the fan that can adversely affect the aircon’s performance and avoid the risk of repair.
Daikin aircon always looks great when it is newly installed in your building. To retain this exterior appearance, you need to regularly clean its air outlet with a microfiber cloth as the top of the aircon can collect dust easily. Therefore, clean it with a clean microfiber cloth to retain its appealing look. However, to clean its front panel, you need to remove the panel first and clean it with normal water and non-abrasive soap. Then dry it completely and return to its initial position.
Furthermore, if you see any of these following signs, you need to schedule an appointment with a professional aircon service or Daikin professional to prevent the complete break of your aircon unit. These signs may include buzzing, vibrating noise, leakage issues, cranking noise, and the likes.
