Zone Air® Thin-Air 3 ZONE 31,500 BTU (11K+11K+9.5K) 22 SEER2 230V Concealed Mini-Split Heat Pump System - Up to 1,575 Sq Ft

Two 11K Zones Plus a 9.5K Zone — Completely Hidden 3 Zone Comfort for Larger Areas

This 3 zone Thin-Air system hides 11,000 BTU air handlers above two larger areas and a 9,500 BTU handler above a third — up to 1,575 square feet total (550 + 550 + 475) from a single outdoor condenser. Nothing shows in the rooms but discreet supply and return grilles. Each zone runs independently with its own thermostat and wired or wireless control.

Three pre-charged R454B linesets ship in the box with hand-tight quick-connect fittings, so the refrigerant circuit stays sealed — no vacuum pump, no manifold gauges, no EPA Section 608 license. Rated 22 SEER2 with heating down to -13°F and 39 dB operation per unit. The condenser is rated 27,000 BTU/h with 31,500 BTU/h of indoor capacity connected, and every handler includes an integrated condensate pump.

Why You'll Love It

• Invisible in Every Room — All three slim handlers hide above the ceiling, in a soffit, or in a closet. Only the grilles are visible, which suits historic renovations and finished interiors.
• Capacity for Two Larger Areas — Two 550 sq ft zones plus a 475 sq ft zone, with each handler able to feed two or three nearby registers — the largest indoor capacity of any Zone Air 3 zone concealed bundle.
• Ultra-Quiet Operation — Around 39 dB per unit, and because the handler sits outside the room, what you hear is air movement at the grille rather than a fan on the wall.
• Sealed Refrigerant Circuit — Three pre-charged linesets with quick-connect fittings mean no vacuum pump, no gauges, and no EPA license for the refrigerant side of the job.
• 5-Year Warranty Protection — Zone Air backs all three handlers and the condenser with a 5-year parts and 7-year compressor warranty, plus 30-day returns on uninstalled systems.

What Makes It Different

Concealed ducted systems are normally the most contractor-dependent option, because the refrigerant work, the ductwork, and the ceiling access all land in one job. Zone Air removes the refrigerant half.

• Three Pre-Charged Linesets — Every line run arrives factory-sealed with R454B inside. Connect each handler by hand, torque to spec, and check the joints — the circuit never opens.
• Understood Connection Ratio — A condenser rated 27,000 BTU/h carries 31,500 BTU/h of connected indoor capacity. Three zones seldom peak together, so the inverter compressor shifts output to whichever zones are calling. Both figures appear in the spec table below.
• Adjustable Static Pressure — Each handler runs 0.1–0.4" WG with duct runs up to 15 feet per supply, so short runs can be tuned to the layout you actually have.

How It Works

1. Place Three Handlers — Locate each slim handler above the ceiling, in a soffit, or in a closet, with service access for filters, and plan short duct runs to the supply grilles.
2. Duct, Connect, and Check — Run the short supply and return ducts, route each pre-charged lineset back to the condenser, hand-thread the couplings, and torque to spec.
3. Power, Drain, and Pair — Wire the outdoor unit to a dedicated 230V circuit (a licensed electrician is recommended for the disconnect), route condensate from each built-in pump, then set up wired or wireless control per zone.

Who It's For

This 9.5K + 11K + 11K concealed system is for:

• Luxury homes and historic renovations where no equipment should be visible
• Two larger areas plus one smaller room, each needing its own thermostat
• Layouts with ceiling, soffit, or closet space for a slim handler and short duct runs
• DIYers comfortable with the most involved Zone Air install in exchange for a fully hidden result

Only one larger area? The 3 zone 30K concealed system pairs one 550 sq ft zone with two 475 sq ft zones.
