Where Can a Mini Split Go in Your Home?
Without ductwork tying you down, a ductless unit fits almost anywhere that needs its own comfort. That flexibility suits rooms a whole-house system cannot reach. Our technicians pick each placement for airflow and looks before drilling.
Here are the spaces our ductless systems serve:
- Garage workout rooms
- Finished basements
- Converted attics
- Home additions
- ADUs and garage conversions
Sun Glow handles the installation, from the refrigerant lines to the final test. Your technician explains where each indoor unit will sit and how the lines will run before work begins. That plan keeps surprises off the job site and off your bill.

Ductless Mini Split FAQ
A mini split looks simple on the wall, but the questions run deep. Sun Glow hears these on service calls every season. Here are the ones that come up most.
Why Do So Many Portland-Area Homes Need Ductless?
Many ranch-style homes from the 1960s and 70s in Beaverton and Gresham were built without ducts to every room. Additions and converted garages have no easy path for new ducts. A mini split solves that without opening your walls or ceilings.
Do Ductless Systems Handle Portland Winters?
Our winters run mild, but an ice storm or cold snap can catch an underrated system off guard. Many cold-climate ductless models hold their efficiency down to around 5°F, which is colder than Portland gets. A system rated for that range keeps your room warm through a hard freeze.
