What should I pay attention to when accepting capacitors in my company
Two common signs that an AC capacitor is failing or has gone bad are: first, your air conditioner is having a hard time starting up or won''t start at all; it might hum or click instead of kicking on as usual. Second, your AC might start up but struggle to cool your home efficiently, running longer than it should or not blowing cool air.
