What's On UEN-TV

 

Home Diagnosis

Presented by Georgia Public Broadcasting, "Home Diagnosis" is "This Old House" meets "CSI". It is the first program ever dedicated to promoting measured home performance, building science concepts & forensic testing, while highlighting best practices for home improvements/high performance building proven through diagnostics. Led by YouTube Home Performance expert Corbett Lunsford and his wife Grace, they travel the nation in their high performance tiny house, # TinyLab, the foil for each episode's home. Along the way, they meet with homeowners to diagnose their mystery problems and prescribe real solutions to help them prove their home is a safe, healthy, comfortable place for their family, as well as addressing the public television audience and informing them on how these lessons can apply in their homes as well.
