How to clean central air conditioner
With the arrival of summer, the frequency of use of central air conditioners gradually increases. However, after long-term use, dust, bacteria and mold easily accumulate inside the air conditioner, which not only affects the cooling effect, but may also be harmful to health. Therefore, it is crucial to clean your central air conditioner regularly. This article will introduce you to the cleaning methods, steps and precautions of central air conditioners in detail.
1. The necessity of cleaning central air conditioners
After long-term operation of the central air conditioner, a large amount of dust and bacteria will accumulate in the filter, evaporator, condenser and other components, leading to the following problems:
| question | influence |
|---|---|
| Reduced cooling effect | Dust blockage leads to poor airflow and reduced cooling efficiency |
| Air quality deteriorates | Bacteria and mold spread through the air, causing respiratory diseases |
| Increased energy consumption | System operation resistance increases and power consumption increases |
2. Central air conditioner cleaning steps
Central air conditioning cleaning mainly includes cleaning of filters, evaporators, condensers, air ducts and other components. Here are the specific steps:
| steps | How to operate |
|---|---|
| 1. Turn off the power | Ensure safety and avoid risk of electric shock |
| 2. Clean the filter | Remove the filter, use a soft brush or vacuum cleaner to remove dust, then rinse with clean water and let dry |
| 3. Clean the evaporator | Spray it with special detergent, let it sit for 10 minutes and then wipe it with a soft cloth. |
| 4. Clean the condenser | Use a high-pressure air gun or soft-bristled brush to remove surface dust |
| 5. Check the air duct | If the air duct is seriously contaminated, it is recommended to contact a professional team for deep cleaning |
| 6. Disinfection and sterilization | Spray with air conditioner-specific disinfectant to kill remaining bacteria |
3. Recommendations for cleaning frequency of central air conditioners
Depending on the environment and frequency of use, the cleaning cycle of central air conditioners varies:
| Usage scenarios | Recommended cleaning frequency |
|---|---|
| home use | Clean the filter every 2-3 months and deep clean once a year |
| office | Clean the filter once a month and deep clean every six months |
| public places | Clean filters every two weeks and deep clean quarterly |
4. Things to note when cleaning central air conditioners
1.Safety first: Be sure to turn off the power before cleaning to avoid electric shock.
2.Avoid rinsing directly with water: The circuit part is strictly prohibited from contact with water to avoid damage to the equipment.
3.Choose a dedicated cleaner: Ordinary cleaners may corrode air conditioner components, so neutral or air conditioner-specific cleaners must be used.
4.Replace filters regularly: For replaceable filters, it is recommended to replace them regularly according to the instructions.
5.Professional cleaning services: For complex components such as air duct systems, it is recommended to contact a professional cleaning team.
5. The difference between DIY cleaning and professional cleaning
| Project | DIY cleaning | Professional cleaning |
|---|---|---|
| Cleaning range | Surface visible parts only | Including all systems such as air ducts and hosts |
| cleaning tools | basic tools | Professional equipment |
| Disinfection effect | Average | Thoroughly |
| cost | low | higher |
