  Does AC refrigerant have oil in it?

  Yes, many air conditioning (AC) refrigerants contain oil. Oil circulates throughout the air conditioning system along with refrigerant to lubricate various components such as the compressor. This oil is critical to the proper operation and longevity of your air conditioning system. Different types of refrigerants may have different oil formulations, so the appropriate oil must be used for the specific refrigerant being used.

  What happens if you put refrigerant in the high side?

  Introducing refrigerant into the high-pressure side can cause several problems:
  ① Compressor damage: The compressor is designed to handle low-pressure gas on the suction side. Introducing refrigerant into the high-pressure side may overload the compressor with high-pressure gas, which may cause damage or failure.
  ② Safety hazard: The refrigerant pressure and temperature on the high-pressure side are higher, and it may be dangerous to try to add refrigerant to this side. There is a risk of injury from the release of high-pressure refrigerant.
  ③ Inefficient system operation: Adding refrigerant to the high-pressure side may destroy the normal operating pressure and temperature within the system. This can result in poor cooling or heating performance and possibly increased energy consumption.
  ④ System contamination: Introducing refrigerant into the high-pressure side without proper draining and recovery procedures may cause refrigerant and system contamination. Contaminated refrigerant can negatively impact system performance and life.

  Do you recover refrigerant from high or low side?

  When recovering refrigerant from an air conditioning or refrigeration system, it is generally recommended to recover it from the low side. The lower side of the system is the suction side, where the refrigerant is in a gaseous state and is at a lower pressure.
  Recovering refrigerant from the low side helps prevent potential compressor damage. If you were to recover refrigerant from the high side (the discharge side), where the refrigerant is in a high-pressure, high-temperature state, it could lead to compressor damage and pose safety risks.

  How do I keep my automatic transmission healthy?

  Keeping your automatic transmission healthy is critical to your vehicle's overall performance and longevity. Here are some suggestions to help keep your automatic transmission in good condition:

  ① Check the transmission oil regularly: Please follow the vehicle manufacturer's recommendations to check and replace the transmission fluid. Make sure the transmission fluid is at the proper level and in good condition. If levels are low or there are signs of contamination, address the problem immediately.

  ② Follow maintenance intervals: Follow the recommended maintenance intervals listed in the vehicle manual. Regular maintenance, including fluid changes and filter replacements, is critical to a healthy transmission.

  ③ Use the correct transmission fluid: Always use the type of transmission fluid specified in the vehicle manual. Using the wrong fluid can result in poor performance and potential damage.

  ④ Warm up your vehicle: Let your vehicle warm up before driving, especially in cold weather. This helps the transmission fluid reach its optimal operating temperature, thereby increasing its effectiveness.

  ⑤ Avoid excessive idling: idling for a long time will cause the gearbox to overheat. If you need to idle for long periods, consider placing the vehicle in neutral to reduce stress on the transmission.

  ⑥ Fix transmission leaks: If you notice any signs of transmission fluid leakage, such as spots under the car or a burning smell, investigate and repair the problem immediately to prevent low fluid levels and potential damage.

  ⑦ Check the cooling system: Make sure the transmission cooler and cooling system are working properly. Overheating can cause transmission problems, so regular maintenance of your cooling system is crucial.

  How to clean automatic transmission?

  The task of cleaning your automatic transmission is best performed by a professional mechanic or a professional car service center. However, if you are looking for ways to maintain and service your automatic transmission, there are some general tips you can follow.
  ① Check the fluid level and condition
  Transmission fluid should be at the correct level and should be clean, clear and not blackened or burnt. If the fluid is low or in poor condition, the fluid may need to be replaced.
  ② Transmission Fluid Change
  If your transmission fluid needs to be changed, follow the recommendations in your car's manual.
  ③ Transmission Flush
  Some mechanics recommend flushing the transmission regularly to replace all fluids. Opinions on this vary, however, and some manufacturers recommend against it. Check your vehicle's manual and consult with a professional mechanic to determine the best method for your specific model.
  ④ Replace the transmission filter
  Some vehicles have a transmission filter that should be replaced when the fluid is changed. Check your manual for information on your specific model.
  ⑤ Solve transmission leakage
  If you notice any transmission fluid leaks, address them immediately. Leaks can cause the fluid level to become too low, causing serious damage to the transmission.
  ⑥ Use transmission additives
  Some people use transmission additives to help clean and protect the transmission. However, it is crucial to use additives that are compatible with your vehicle and follow the manufacturer's recommendations.
