Zone Air concealed mini split system hidden above the ceiling with discreet vents for invisible heating and cooling

Concealed (ducted) mini splits hide completely above the ceiling or in an attic. Only small supply and return grilles are visible in the room — the air handler, refrigerant lines, and ductwork are all out of sight. Ideal for homeowners who want powerful heating and cooling without any visible equipment.

How They Work

A compact air handler installs above the ceiling and pushes conditioned air through short duct runs to recessed vents. Unlike central air with long ductwork throughout the house, ducted mini splits use short runs (under 15 ft) that avoid the 20–30% energy loss typical of traditional systems.

Installation

Concealed systems need 8–12 inches of clearance above the ceiling. Our pre-charged linesets simplify the refrigerant connection, but we recommend working with an HVAC contractor on the ductwork layout. All models require 208–230V service and include a built-in condensate pump.

Efficiency & Noise

Up to 19.6 SEER2 with inverter-driven compressors. Indoor noise runs at just 39 dB in quiet mode — with the air handler tucked above the ceiling, sound in the room is minimal. A single unit can condition 2–4 rooms depending on duct layout.

What's Included

Slim-duct indoor air handler, outdoor condenser, pre-charged 16 ft lineset, wireless remote, built-in condensate pump, and all installation hardware. Ductwork and grilles are sourced separately to match your layout. 5-year parts / 7-year compressor warranty with live support (9–5 MST).

Frequently Asked Questions About Ducted Mini Splits

Common questions about concealed mini split systems, installation, and pricing.

What is a concealed mini split?

A concealed mini split hides the indoor unit completely above the ceiling in an attic or ceiling cavity. Short duct runs deliver heated or cooled air through discreet ceiling vents to the rooms below. Only the vents are visible — the unit itself is completely hidden, making it the most aesthetically clean HVAC option available. Compare this with wall mount systems or ceiling cassettes to find the best fit for your space.

How is a ducted mini split different from central air?

Ducted mini-split systems use short, small-diameter duct runs rather than the full-house ductwork required by central air systems. They are more energy efficient, easier to install, and can be added to homes without existing duct systems. Each unit operates independently as a heat pump with its own thermostat, and pre-charged linesets make DIY mini split installation possible.

Can a concealed mini split cool multiple rooms?

Yes — a single concealed mini split can cool 2 to 4 rooms depending on the unit size and duct layout. Short duct runs branch from the indoor unit to ceiling vents in each room. For example, a 12K BTU ducted unit can comfortably condition a master bedroom, bathroom, and walk-in closet from a single unit installed in the attic. For two fully independent zones, consider a dual zone bundle with two indoor units and one outdoor condenser.

What does ducted mini split installation involve?

Installation involves mounting the indoor unit in the ceiling cavity or attic, running short duct sections to room vents, connecting refrigerant lines to the outdoor condenser, and completing electrical wiring. Zone Air systems include pre-charged linesets to simplify the process. Ducted installations require more planning than wall mount units but are less invasive than full central ductwork. Visit our FAQ page for more installation details.

How much does a concealed mini split cost?

Zone Air concealed mini split systems start at $2,299 for the 9K BTU model and $2,699 for the 12K BTU model. The dual zone concealed bundle is $4,899 and covers two rooms with independent temperature control. All prices include the indoor unit, outdoor condenser, pre-charged lineset, and installation hardware.
