The average cost to replace an AC capacitor typically ranges from about $120 to $250, which includes the price of the part and the labor to install it. The exact cost can vary depending on the type of capacitor your AC …
How To Test a Capacitor
If we read a very high resistance across the capacitor (several MΩ), this is a sign that the capacitor likely is defective as well. It is reading as if there is an open circuit across the capacitor. A normal capacitor would have a resistance reading up somewhere in between these 2 extremes, say, anywhere in the tens of thousands or hundreds of thousands of …
