The right size is often smaller than what you have
A lot of Panama City homes run equipment a half-ton to a full ton larger than the house needs, because at some point somebody sized it by square footage on the back of an invoice. Oversizing feels safe. It is not — a unit that is too large hits the set point fast and shuts off before it has pulled moisture out of the house. That is the complaint we hear constantly: the thermostat says 72 and the house still feels sticky.
