In this Part 2 of "Our Journey" in attempting to solve an issue with our home Central AC unit we'll be showing you how to disconnect, discharge and test the capacitance of a dual-run capacitor using a multimeter. We will give you a background and more information below but first, here are the #ᴬᴰlinks to some of the components, parts and tools required for this repair:

Background:
On one hot summer afternoon, my mom noticed that our air coming from our vent inside the house was warm instead of cold. We can hear and see the fan on the outside unit running. Similarly the indoor unit appear to be working functioning normally but it's not cooling.
When my dad check the condenser unit outside, he said he couldn't hear the compressor humming. Therefore we think there is something wrong with either the compressor, the capacitor or the wiring itself.
My dad is not an expert in HVAC but he has worked on and has helped a couple of his friends saved several thousand dollars in AC repairs. This is an opportunity for me to learn about heating, venting, air conditioning and refrigeration field work, which I'm sure will be helpful in the future especially right now I'm studying Mechanical and Electrical Engineering at Harvard University in Cambridge, Massachusetts. We hope this tutorial video can be your HVAC DIY guide as well.
We're seriously hoping there is nothing wrong with the compressor because it would be extremely expensive to replace the compressor and due to the age of the entire system it might not be worth it because of the labor involved in welding, brazing, soldering the AC lines and purging the contaminants using nitrogen. Beyond just cost, if your compressor is no longer under warranty and the whole system is more than eight to 10 years old, it might be worth it to replace the whole system. And we don't want to have to do it.
So far we know that the capacitor is bad.
AC repair safety precautions:
Have the right protective gear - insulated gloves, goggles, or face shields, non-slip shoes
Double check connections after reassembling - wiring harnesses, plugs, verify polarity
Failure to do so can lead to serious injury and property damage.

The basics of cooling your home is about removing heat from the refrigerant. This is done by turning the refrigerant by compressing and decompressing the refrigerant to transform it from a liquid to a gas and back to a liquid. As the refrigerant is compressed, it becomes hot. When it is decompressed, it becomes cold.
There are 2 units used in the typical residential AC system
Outdoor Unit: is often called the Condenser Unit. It is a rectangular box sitting out of the house. Key components located in the outdoor unit is the compressor, the condensing coils, and a large fan.
Indoor Unit: is typically attached to the furnace system. They share a common blower fan to blow conditioned air into the house through the ducts and vents. Key components located in the indoor AC unit are the evaporative expansion valve, the evaporator coils, and the blower fan. Sometimes this is called an air handler.
