The Situation
Room Addition — No HVAC
Homeowner completed a room addition but didn’t extend the existing HVAC ductwork during construction. The new room had no heating or cooling. Running new ductwork through finished walls would be expensive and destructive.
  • New room addition with no HVAC connection
  • Extending ductwork not practical (finished walls)
  • Room approximately 250 sq ft
  • Needed both heating and cooling year-round
