Residential HVAC System Diagram
Upstairs bedrooms that run hot all summer are a familiar headache in a two-story house. ArcSite's residential HVAC system diagram shows a basement furnace serving the first floor and an attic air handler serving the second, with every supply and return marked.
Key Features
This residential HVAC system diagram includes:
- Two-story house in cutaway view
- Basement furnace feeding the first floor
- Four first-floor supply registers
- First-floor return running back to the furnace
- Attic air handler serving the second floor
- Two second-floor ceiling supplies
- Second-floor ceiling return
- Attic vent in the roof
Each floor here has a single return, so rooms with closed doors may need a jumper duct or a door undercut to get air back to it.
