Ductless Mini-Split Installation in Burien, WA
Ductless mini-splits solve the problems ducted systems can't: the bonus room that's always too hot, the garage office, the addition that never got connected to the furnace, or the whole house that simply has no ducts at all.
Burien is dominated by solid mid-century construction from Seahurst to Gregory Heights — homes with good bones that often still run furnaces well past their design life. That's exactly where mini-splits shine — precise room-by-room control, whisper-quiet operation, and both heating and cooling from one wall unit.
Where Mini-Splits Make Sense in Burien
A single-zone system handles one problem room. A multi-zone setup — several indoor heads running off one outdoor unit — can condition an entire home without a single duct. The right answer depends on your layout and how you actually use your spaces.
We size each zone properly, place heads where they'll actually distribute air well, and quote the whole job in writing before we start. Most single-zone installs are done in one day.
From Three Tree Point to Boulevard Park, Burien is about 18 minutes from our Kent shop via SR-509 or I-5.
