What does harbor-front living do to Old Village HVAC systems?

The Old Village is Mount Pleasant's original neighborhood - a walkable grid of homes from the 1800s through the mid-20th century, anchored by the Pitt Street Bridge, Alhambra Hall, and the working waterfront of Shem Creek. Many of the older houses still have lath-and-plaster walls with little to no cavity insulation, which means big thermal loads, rooms that never quite even out, and short-cycling when someone pairs modern high-capacity equipment with the house's original restrictive duct paths.

Sitting directly on Charleston Harbor, the Old Village also takes relentless salt exposure. Standard aluminum-fin coils pit and leak here years ahead of schedule, so coastal-coated condensers and a disciplined rinse-and-inspect schedule aren't upsells - they're how equipment survives. Exterior changes in the historic district go through the Town of Mount Pleasant's preservation review, so ground equipment belongs on rear elevations with proper screening.

Salt air on a first-name basis

Blocks from open harbor water, condenser coils corrode fast. We specify factory coastal coatings, place units out of direct spray lines where possible, and rinse coils at every maintenance visit.

Historic-district placement rules

Exterior alterations in the Old Village historic district go through town preservation review, and equipment should stay off street-facing elevations. We plan changeouts and new installs so screening and placement pass review cleanly.

Uninsulated plaster walls, uneven rooms

A 19th-century house with empty wall cavities can't be fixed by a bigger blower. Load calculation, duct corrections, and sometimes a dedicated ductless head for the stubborn room deliver comfort the right-sized way.

What HVAC rebates can Dominion Energy customers here claim?

Most homes in this neighborhood are Dominion Energy South Carolina electric customers, and Dominion's residential program pays $400 to $500 toward a new ENERGY STAR qualified central air conditioner or heat pump ($400 at 15.2 SEER2, $500 at 16.0 SEER2), $650 when you replace an electric furnace with an ENERGY STAR heat pump, and up to $300 for ductwork sealing, insulation, or replacement.

The fine print matters: equipment must replace the same type of system (no fuel switching), it must be installed by a licensed mechanical contractor like All Star, and the application has to be in within 90 days of installation. We handle the paperwork on qualifying installs. South Carolina's federal HEAR/HOMES rebates are not open yet (the SC Energy Office expects a 2026 launch), and the old federal 25C tax credit expired December 31, 2025, so these utility rebates are the real money on the table right now.
