Mini-Split Installation FAQ for Charleston Homeowners

How often should Charleston homeowners get mini-split installation?
Given Charleston's hot, humid subtropical climate averaging 90°f in summer with high dewpoints, most homeowners benefit from mini-split installation at least once a year. Year-round termite monitoring (one of the worst cities in the US for termites) often makes spring or fall the optimal time to schedule service.
What home types in Charleston most need mini-split installation?
Single and double-pile Charleston single house style (architectural signature) and Antebellum mansions on the Charleston Peninsula are the most common home types in Charleston and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
What's the difference between a mini-split and central HVAC?
Central HVAC uses ductwork to distribute conditioned air from a single air handler. Mini-splits have individual indoor units in each zone — no ductwork, no duct losses, and independent control for each room.
How many zones do I need?
One per room or area you want to control independently. Multi-zone outdoor units can support 2–8 indoor units. Single-zone systems (one indoor unit) are common for additions, garages, and bedrooms.
Can a mini-split heat in winter?
Yes. Most mini-splits include a heat pump mode for both heating and cooling. Cold-climate models (Mitsubishi, Daikin, Fujitsu Halcyon) maintain heating capacity down to -13°F.
Are mini-splits expensive to run?
Mini-splits are among the most energy-efficient HVAC systems available, with SEER ratings of 20–30+ compared to central systems at 14–18 SEER. Operating costs are typically 30–50% lower than conventional systems.
