Capacitors
Capacitors on a heating and cooling units are used to help motors get started and keep motors running properly. I compare capacitors to the battery of a car. If the capacitor is weak the motor/compressor may not start up or overheats after it runs for a little bit.
Capacitors should be checked each maintenance. My own Air Condition had a capacitor that was starting to get weak,but not at the point that it had to be changed. Well two months later I had to change it. The top of my capacitor looked like a bullfrog. A tech should have a meter to check the capacitors to see its strength level or resistence level. If a tech says a capacitor needs replacing ask him to show it to you, just say so you can tell your spouse. I always show my customers just to make them feel comfortable with me. Weak capacitors can damage the motor/compressor and cause higher electric bills. Capacitors are suppose to be changed once the get 10% of their rated value. I would suggest changing them even if its borderline due to my own personal experience, cause two months later I had to change mine. This will save a service call charge and the inconvience. Next visit I will address contactors.
