Heat and cool any space — no ductwork required.
Cooling
Got a garage gym that is unusable by June? A room over the garage the rest of the house forgot? A porch conversion, an addition, or an older island cottage that never had ducts at all? A ductless mini split fixes exactly that. Alexander Heating & Cooling installs Mitsubishi mini split systems across the Charleston area — compact, quiet, and controlled room by room.
A small wall unit inside, a compact condenser outside, and one small penetration between them. Perfect for additions and older homes.
Nearly every mini split we install is a heat pump — comfortable in a Charleston August and warm in a January cold snap.
Each zone has its own control. Stop paying to condition rooms nobody is using.

How It Works
Give us a call at (843) 608-1689 or fill out the form. We will ask a few questions about what is going on.
Our technician finds the real problem and gives you clear pricing before any work starts.
We finish the job, clean up after ourselves, and test everything before we leave. Done means done.
Garages and garage gyms — one recent customer had us install an 18,000 BTU Mitsubishi mini split in his garage gym and called the work "outstanding craftsmanship" in his review. Rooms over garages that bake all summer. Sunrooms and enclosed porches. Additions where extending the ductwork would cost a fortune. And the older beach cottages on Sullivan's Island and Isle of Palms that were built long before central air existed. One small unit, and the space finally matches the rest of the house.
Most single-zone installations are finished in a day: we mount the indoor unit, set the outdoor condenser, run the line set, and test both heating and cooling before we leave. Multi-zone systems — one outdoor unit feeding several rooms — take a bit longer, and we map the layout with you before any work starts.
