Why ductless fits Mountlake Terrace homes

  • • Older homes and condos often lack efficient ducting—ductless avoids attic and garage heat loss while offering room-by-room control.
  • Ideal for basements, home offices, and ADUs, common in Mountlake Terrace.

  • • Inverter technology ensures energy efficiency, maintaining comfort in both cold winters and warm summers.

  • • Discreet installation with color-matched line-set covers and hidden outdoor units that blend with your home.

Single-Zone vs. Multi-Zone — What’s Right for Your Layout

Single-zone systems are perfect for bedrooms, home offices, or small additions.

Multi-zone setups (2–6 indoor heads) allow one outdoor condenser to power multiple rooms, each with its own thermostat.

Our Mountlake Terrace installation process includes:

  • Load calculations for correct BTU sizing

  • Core drilling with dust control and weatherproof sealing

  • Insulated line-sets and condensate routing (pump or gravity)

  • Dedicated electrical circuits and full permit coordination

  • Startup testing, control setup, homeowner training, and cleanup

Most single-zone installs: 1 day
Multi-zone installs: 1–2 days depending on layout and wiring.
