What to Look for in a Charleston HVAC Professional
Not all hvac services providers in Charleston operate at the same standard. Here are the credentials and practices that distinguish the best from the rest:

HVAC Services Costs in Charleston: What to Expect
HVAC service calls typically run $75–$200 for diagnostics, with repairs ranging from $150 for a capacitor replacement to $1,800+ for a compressor swap. Full system replacement averages $5,000–$12,000 for a residential system, depending on home size, efficiency rating, and whether ductwork needs modification.
Charleston's competitive contractor market tends to keep prices near or slightly below the national median. The region's lower cost of living translates to accessible pricing, though demand spikes after storms or peak seasons can temporarily push rates up. Multiple quotes still protect you.
When to Call a Professional
Call immediately if your system is blowing warm air during summer heat, if you hear grinding or screeching sounds from your air handler or outdoor unit, if you smell burning or notice ice forming on refrigerant lines, or if your system short-cycles (turns on and off rapidly). In extreme heat or cold, HVAC failure is a health emergency for elderly residents and young children. Most licensed contractors offer same-day or next-day emergency service.
