Central air installation cost varies by home and system, and Fix-it 24/7 confirms final pricing only after an on-site inspection. The largest price swings usually come from matching system capacity to your home and what’s needed to support safe, efficient operation.
We typically finish most residential installations in one day, and we handle permits and code compliance for the Charleston area. We also provide a free in-home consultation and estimate before work begins. One thing we see often: tight attic or crawlspace access can add labor time more than homeowners expect.
Key factors that change price:
- System size (tonnage) and efficiency rating (SEER/ENERGY STAR)
- Ductwork condition or new duct design for spaces without proper supply/return
- Electrical upgrades, refrigerant line set length, drain, and pad/stand needs
- If your current unit is 10–15+ years old or uses R-22 refrigerant, replacement usually beats a major repair
Ask for a written scope listing equipment model, efficiency, and any duct or electrical work before you approve the job.
