Slide 2: Air Conditioner
•
The air conditioner is similar to a refrigerator, in the sense that, they use energy to pull heat out of cool interior space. An air conditioner is responsible for cooling a larger area, which means that knowing how the unit works and what repairs are needed is crucial to staying comfortable all summer long.

Slide 3: How Air Conditioners Work
•
Air conditioners consist of three important parts: the compressor pump, condenser, and evaporator coils. These parts pass refrigerant through each other that extracts heat from the air around it and turns it into a gas. The refrigerant gas is then pumped to the compressor and is heated into a liquid again to start the process over.
