Why Are the Back Bedrooms Always Warm in Older West Ashley Homes?
The Ducts Came Later
The back bedrooms run warm in many Avondale, Byrnes Down and Windermere homes because central air was added after the house was built. The ducts run long under the floor, lose air through leaks and arrive weak at the far rooms.
| Symptom | What We Find Under the House |
|---|---|
| Far rooms 3 to 6 degrees warmer | Long runs, sags and disconnected joints |
| Sweating vents in summer | Duct insulation soaked or missing |
| Musty air when the AC kicks on | Wet ducts and standing water |
| Ducts too small for the new unit | Original sizing from decades ago |
Repair or Replace West Ashley Crawl Space Ducts?
Repair ducts that are mostly sound with a few leaks. Replace them when the insulation is soaked, the runs are crushed or the sizing is wrong for your system.
- Duct sealing: $800-$2,500+.
- Full crawl space duct replacement: $2,500-$7,500+.
- Encapsulating the crawl space when moisture keeps winning.

Ductless Mini Splits for West Ashley Sunrooms and Additions
No New Ducts Needed
A ductless mini split is often the best fix for a West Ashley sunroom, garage conversion or addition the main system can't reach. It mounts on the wall, runs quiet and cools only that space.
| Room | Typical Mini Split Price |
|---|---|
| Sunroom or Florida room | $3,500-$6,000+ |
| Garage conversion | $3,800-$6,500+ |
| Two rooms, one outdoor unit | $6,500-$10,000+ |
Can I Just Add a Vent From the Main System?
Sometimes, but in older West Ashley homes the main system is usually already stretched. Adding a vent can starve the rest of the house, so we check capacity first.
