Air conditioning in homes is about reliable cooling, indoor comfort, and mechanical performance that holds up through Missouri summers, when temperatures climb into the 90s and humidity tests every component in the system.
A bigger air conditioner is not a better one, and in the Ozarks, that lesson gets learned the humid way. When a system is oversized for the space, it cools the air fast, shuts off, and never runs long enough to pull the moisture out.
