An air conditioner (AC) compressor is a mechanical device that compresses refrigerant gas, raising its pressure and temperature. Oil is added to the compressor to lubricate its moving parts and to help cool it down. Over time, the oil level in the compressor can decrease due to leaks or evaporation. This can lead to premature wear and failure of the compressor. Adding oil to the compressor is a relatively simple task that can be done by most homeowners with basic tools.
There are several benefits to adding oil to the AC compressor. First, it helps to lubricate the moving parts of the compressor, reducing wear and tear. Second, it helps to cool down the compressor, preventing it from overheating. Third, it can help to extend the life of the compressor, saving you money in the long run.
