What the climate around Mount Pleasant means for windows
For homes around Mount Pleasant, heating and cooling both matter: compare U-factor and solar heat gain together on the NFRC label rather than optimizing one side of the year. The station's annual mean temperature is near 66°F with about 52 inches of precipitation, so flashing and water management around the opening deserve the same written attention as the glass package.
Climate figures are NOAA 1991-2020 normals recorded at SULLIVANS IS, SC US (near Mount Pleasant); they describe the recording station's location, not any specific property.
Comparing window performance the measurable way
South Carolina's ENERGY STAR Version 7.0 zone criteria (South-Central: U-factor ≤ 0.28, SHGC ≤ 0.23; Southern: U-factor ≤ 0.32, SHGC ≤ 0.23) set the qualifying levels; the county's zone determines which applies to a Mount Pleasant home. Whole-product NFRC ratings on the exact quoted window are the comparable basis, and no rating supports a guaranteed savings figure for an individual home.
Planning ranges for Mount Pleasant
The published Window Replacers planning range for a representative vinyl replacement scenario in the Mount Pleasant area is $400–$1,000 per opening, produced by the versioned pricing methodology from official labor and regional price data. A planning range is not a quote: only a written proposal from a professional who has evaluated the specific openings can state a price.

Openings, scope, and what belongs in writing
Before comparing vinyl replacement proposals in Mount Pleasant, document the openings themselves: frame construction and reinforcement; style and size. Homes built before 1978 add a federal consideration: work that disturbs painted surfaces falls under the Renovation, Repair and Painting rule, so confirm the construction year and ask how containment will be handled.
