All of the following are heating systems found in Florida homes, EXCEPT:

The choice of ACMS as the answer is accurate because it does not represent a commonly recognized heating system used in Florida homes. Typically, heating systems found in Florida include heat pumps, boilers, and radiant heaters, all of which utilize specific mechanisms suited to various heating needs.

Heat pumps are particularly popular in Florida due to the state's climate. They work by transferring heat rather than generating it directly and can provide both heating and cooling, making them very efficient for homes in warmer regions.

Boilers are also utilized, primarily in homes that require hot water for heating purposes. They function by circulating hot water or steam through radiators or underfloor heating systems.

Radiant heaters are another option, which warm the surfaces of a room and can be effective in localized heating.

In contrast, ACMS does not correspond to a known heating system and appears to reflect a potential misunderstanding or an acronym that is not commonly used in this context, which makes it the clear choice as the system not found in Florida homes.
