Ductless Mini-Split Systems — Installation & Replacement

Room-by-room comfort without ducts. A ductless mini-split uses a small outdoor unit and one or more slim indoor heads to cool and heat specific areas. It’s quiet, efficient, and perfect when you want targeted comfort without tearing into walls for ductwork.

How it works (simple)

Each indoor head conditions the room it’s in and has its own remote or app control. The outdoor unit moves heat out in summer and brings gentle warmth in winter. No ducts, less energy loss, and precise temperature where you actually live.

Is a mini-split right for you?

  • Homes without existing ducts or with limited attic/crawlspace access
  • Additions, ADUs, garages, sunrooms, or that one room that’s always too hot or too cold
  • Zoned control: set different temps for different spaces
  • Quiet operation—great for bedrooms and home offices

Installation process

  1. On-site assessment: We check room sizes, electrical, and placement for indoor heads and the outdoor unit.
  2. Options & clear quote: Single-zone or multi-zone layouts with upfront pricing—no pressure.
  3. Permits & schedule: We handle the paperwork and book your install.
  4. Professional install & start-up: Clean wall penetrations, tidy line sets, vacuum/pressure test, and full system check.
  5. Handoff & tips: We walk you through controls and simple filter cleaning to keep performance high.

Popular configurations

  • Single-Zone: one room or studio
  • Multi-Zone: up to 2–5+ rooms on one outdoor unit
  • Head styles: wall-mount, low-wall console, or low-profile ceiling cassette (where it fits best)
