Are there reasons why one should not reuse untested refrigerants?
We have found that used refrigerant always contain contaminants including oil, moisture, acid, air, and rust. Reusing refrigerants of unknown purity is like playing russian roulette. You never know what’s going to happen. The most common contaminants we find in refrigerants are air, moisture, and oil. Air and oil reduce efficiency and moisture can seriously damage the system. Think about it this way, you wouldn’t take used motor oil from one car and put it into another just to save a few bucks…would you?
