Air conditioners and the end of R-22 refrigerant

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. Older air conditioners that contain R-22 refrigerant are typically going to be cost-prohibitive to service, but it's not illegal to do so.

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.
