How to test and change ac capacitor.
Always be careful with electricity and turn off power to the ac unit before handling or replacing capacitor! Use a multimeter to test wires and connectors to make sure it is safe FIRST.
I performed this simple DIY, by testing and changing my ac capacitor, and in the end, it appears it has lowered my electricity use for the AC by about 1 AMP, which is about 9% !!
Oftentimes, your AC system is running fine, but the capacitor gets out of specifications over time. this can lead to inefficiencies in the system, and testing and replacing the capacitor can get you back into optimum running shape and save you money potentially.
This AC capacitor can be found online for about $15. The specific part and model for your AC will vary, and you will need to look that up.
it is important that you have the proper multimeter that has a "capacitance" setting. This is NOT the same as a resistance or ohms setting.
