Bill, Tessa and Reuben discuss how air conditioners function, why it's extremely unusual to have an undersized air conditioner, and the end of R-22 refrigerant.

We also mention a video compilation we assembled showing 60 home inspection defects in 3 minutes. One of those was an iced-up evaporator coil melting all over the place while the furnace ran.
