Frequently Asked Questions (FAQs)

1. What kind of oil do you put in an air conditioner?

The type of oil you put in an air conditioner depends on the system. Mineral oil is suitable for older AC systems, while newer ones work well with POE oil. PAG oil is commonly used in cars. It's important to check your specific AC unit's requirements and use the appropriate oil.

2. Do air conditioners need to be oiled?

Most current models of air conditioners have motors that do not require oiling. However, older units may need periodic oiling to maintain the fan's condition. It is recommended to perform regular maintenance, including oiling, at the start of the cooling season.

3. What happens if you use the wrong PAG oil?

Using the wrong PAG oil, such as universal oils or oil mixtures, can lead to seizure and damage. Universal oils, which are often preferred by garages, have a different viscosity than synthetic PAG oils, resulting in compatibility issues and potential damage.

4. What oil do you use with 410A refrigerant?

Polyolester oil (POE oil) is a synthetic oil used in refrigeration compressors that is compatible with refrigerants like R-410A, R-134a, and R-12. It is recommended to use POE oil when working with systems that use 410A refrigerant.

5. What happens when compressor oil is low?

Compressor oil is essential for lubrication and preventing damage from friction in reciprocating compressors. If the oil levels drop too low, the compressor can overheat and potentially burn out. Regular maintenance and monitoring of oil levels are necessary to ensure proper functioning of the compressor.

6. Should you spray your air conditioner with water?

Yes, it is safe to spray water on your air conditioner for cleaning purposes. In fact, spraying water on the AC's condenser can help it run more efficiently. Regularly spritzing the condenser with water is recommended to maintain optimal performance.

7. Do I need to add PAG oil when replacing compressor?

When replacing a compressor, it is important to remove as much of the original oil charge as possible to prevent an oil overcharge. However, a small amount of oil may remain in the system, which is usually acceptable as long as it is contaminant-free.

8. Is it OK to mix PAG oils?

No, it is not recommended to mix PAG oils with mineral oils. Water-soluble polyglycols, like PAG oils, are not compatible with mineral oils. Mixing them can result in a gelatinous, gooey mess. It is important to handle and dispose of PAG oils separately to avoid any logistical problems.
