Chicago’s Bungalow Belt is full of homes heated by cast iron radiators, with no ductwork at all. That leaves window units as the default, but you have better options.
Option 1: High-velocity central air
High-velocity systems use an air handler, usually in the attic, and small flexible ducts about two inches across that can snake through closets, between joists and inside walls. Each room gets small round outlets instead of large registers.
- Pros: whole-house cooling, minimal demolition, discreet outlets, good humidity removal.
- Cons: needs attic space for the air handler and careful planning of duct runs.
Option 2: Ductless mini splits
An outdoor unit connects to wall-mounted heads in individual rooms through a small hole in the wall. No ducts at all.
- Pros: room-by-room control, very efficient, most models also heat.
- Cons: visible indoor heads; several heads may be needed for a whole house.
The finished attic question
Many bungalows have a finished attic bedroom, and it’s usually the hottest room in the house. A high-velocity air handler can share that space; alternatively, a single ductless head upstairs is often the quickest win.
What to expect from the project
- A technician measures the house and looks at the attic, closets, electrical panel and where the outdoor unit can go.
- You get options and a free estimate for each.
- Installation usually takes a few days for high-velocity, less for mini splits.
