10 Signs of an AC Refrigerant Leak & What to Do Next
An AC refrigerant leak can be caused by holes or cracks in the coils that circulate the refrigerant. While a hissing sound coming from your AC system could be a sign of a variety of problems, refrigerant leaks are the most common. If the leak is severe enough, your AC may even make a gurgling sound. 8. Low airflow
Why do some capacitors leak and other capacitors hardly leak at …
I just found out that some capacitors hardly leak whereas other types of capacitors leak a lot of current through the dielectric.
