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.
