Ductless Mini-Split Installation in Marietta, GA

Efficient, ductless heating and cooling for additions, older homes, and hard-to-condition spaces — professionally installed across Marietta and Metro Atlanta.

A ductless mini-split is one of the most flexible, efficient ways to heat and cool a space — no ductwork required. Ultimate Home Services Plus designs and installs single- and multi-zone systems for Marietta homeowners who want comfort exactly where they need it.

Mini-splits shine in the situations traditional central air can't handle well: a converted garage or bonus room, a sunroom, an addition, or an older Metro Atlanta home that was never built with ductwork. Because each indoor unit is controlled independently, you condition only the rooms you're using — which is both more comfortable and more efficient.

When a Mini-Split Is the Right Choice

  • Additions & bonus rooms where extending ductwork isn't practical.
  • Garages, sunrooms, and offices that need their own comfort control.
  • Older homes without ducts — common across historic Marietta neighborhoods.
  • Hot or cold spots the central system never quite reaches.
  • Room-by-room zoning so you stop paying to condition unused space.

Why Homeowners Love Ductless

  • High efficiency (SEER2) with no energy lost through leaky ducts.
  • Heating and cooling in one — mini-splits use heat-pump technology, ideal for Georgia's mild winters.
  • Quiet operation and precise, independent temperature control per zone.
  • Compact and flexible — a single outdoor unit can serve multiple indoor heads.

What Our Installation Includes

Every ductless install starts with a proper assessment so each zone is sized correctly:

  • BTU sizing per zone based on room size, sun exposure, and use.
  • Outdoor condenser placement and indoor head mounting.
  • Line set, electrical, and condensate run cleanly and to code.
  • Full testing and walkthrough of your new system and remote/controls.

Mini-Split FAQs

It depends mainly on the number of zones (indoor units) and capacity. A single-zone system costs less than a multi-zone setup. We provide free estimates with clear options and financing.
Yes. Mini-splits use heat-pump technology, so they both heat and cool — a great fit for Georgia's mild winters and a single year-round comfort solution.
It depends on how many separate spaces you want to control. One outdoor unit can serve several indoor heads. We size each zone during your free assessment.
