Where the Money Goes
In an average Chattanooga home, 40% of cooling loss happens at the attic, 20% through the crawl space, and another 25% through air leaks at windows, doors, and penetrations.
How to Cut It
A combination of attic insulation, crawl space encapsulation, and air sealing typically cuts summer bills 20–40%.
- Upgrade attic to R-49+
- Encapsulate the crawl space
- Air seal the building envelope
- Insulate ductwork in unconditioned spaces
