Local Insight — Summerville

AC system design in the Charleston area needs to account for long cooling seasons and substantial latent humidity load. Open floor plans, coastal sun exposure, raised homes, and additions common in Lowcountry properties can all affect airflow and return-air planning. In older homes, retrofit limitations may shape whether a central or ductless strategy makes more sense.

Homeowner Tip

Create a simple list of rooms that run hotter, receive strong afternoon sun, or have doors that stay closed most of the day. This gives useful real-world input when planning supply and return airflow for the new design.

⚠ Do not rely on rule-of-thumb sizing alone when planning a new AC system, especially for additions, renovated homes, or unusual layouts.
