Heating and coolingAirGreen’s Samsung space
The Samsung slim duct: nothing on the wall, 199 mm in the ceiling.
Samsung’s Slim Duct hides above the ceiling and blows into one room through a short duct. It is 199 mm high; Samsung wants 20 mm more under it, a hatch that depends on your ceiling and a static pressure set between 0.01 and 0.24 in. WC. LogisVert: $1,056 (12,000) and $1,944 (18,000).
- 199 mm high, all three sizes
- Built-in condensate pump
- Optional leak detection
Height of all three sizes, per Samsung. Plan on 219 mm: Samsung wants 20 mm more under the unit.

At -8 °C, the 18,000 heats almost twice as much as the 12,000.
Three sizes, two LogisVert amounts. Pick one: models, AHRI number, certified heat at -8 °C and the math. When there is no amount, we tell you why.

35 7/16 in wide (43 5/16 in on the 18,000) by 17 5/16 in deep: it hangs below the joists, in a bulkhead, a closet or a drop ceiling, not between two joists.
For a ceiling install, Samsung asks for at least 2.2 m (7.2 ft) between the floor and the unit.
Samsung intends the Slim Duct for free-air discharge or a duct serving one room only. We plan the duct at the visit.
Samsung lists the Slim Duct among the FJM Premium multi-zone heads: it can replace a wall unit in a bedroom.
Where the air goes, and where the water goes.
The Slim Duct draws room air, heats or cools it, then blows it through a grille. Pick the mode and the return: from the bottom, Samsung warns that noise rises by 3 to 6 dB(A).

Drop tiles: no hatch. Drywall: one or two.
The Slim Duct is 199 mm high and Samsung wants 20 mm more under it: count on 219 mm. For service, it has to be reached from below. Pick your ceiling, the size and the clear height above: we check the room, then the manual’s hatches.
Drywall with less than 50 cm above: two hatches, A, 1,000 mm long (the unit’s width plus 100 mm), and B, 500 mm.
And always: at least 20 mm under the unit, and at least 2.2 m off the floor. Service is from below or from the side, per Samsung.

From 0.01 to 0.24 in. WC: the right range is set at start-up.
Static pressure is the resistance of the ducts and grilles that the fan has to push against. The Slim Duct doesn’t adjust itself: Samsung sets five ranges, and the installer enters the right one with a wired control. Slide to your duct pressure.
Range 2 of 5
Samsung says it plainly: the automatic air-volume function can’t be used on the AC***DNLDCG.
The option code can only be set from the main wired wall control, per the manual.
A wrong code may cause an error or a breakdown, Samsung warns: the installation specialist enters it.
Worth knowing: 0.24 in. WC is the pressure of a water column about 6 mm high. The Slim Duct pushes air through a short duct, not through a whole-house duct network.

Six duct layouts: which ones pass?
Samsung and Hydro-Québec each have rules for Slim Duct ducts. Tap a card, then the right bin: allowed, with a condition, or ruled out.
Tap a card first, then the bin.
Duct to one bedroom. Allowed: Samsung intends the Slim Duct for free-air discharge or a duct serving one room only.
Two rooms. Ruled out: one room per Slim Duct, per the manual. For two rooms, we plan two units or a multi-zone.
Bottom return. Allowed: the manual allows a bottom return. Samsung warns it adds 3 to 6 dB(A).
Drop ceiling as return. With a condition: only if a refrigerant leak detection system is installed, per Samsung. On the Slim Duct, the
Ducts in the attic. Ruled out of LogisVert: Hydro-Québec refuses indoor units and ducts outside the insulation envelope, for example in the attic or roof space.
A spark in the duct. Ruled out: Samsung forbids any auxiliary system in the ducts that could be an ignition source.
Did you know: a drop-ceiling return needs leak detection. It is an option on the Slim Duct, and built into the mini cassette and the console.

Same outdoor unit, three ways to heat the room.
The Slim Duct, the mini cassette and the console run on the same three CAC Premium outdoor units. Pick a size and a measure: the certified numbers show what each format gains or gives up.
Heat certified at -8.3 °C (17 °F) by ENERGY STAR, under each combination’s AHRI number: the “capacity at -8 °C” Hydro-Québec uses for LogisVert.
Cooling certified by ENERGY STAR. Hydro-Québec requires at least 12,000 BTU/h in cooling: that is where the 12,000 console loses its amount.
Seasonal cooling efficiency (SEER2), certified by ENERGY STAR. Higher is better.
Seasonal heating efficiency (HSPF2, region IV), certified by ENERGY STAR. Higher is better.
Sound pressure at the highest fan speed, per Samsung’s submittals. Lower is quieter. Samsung does not publish the test conditions.
Amount on Hydro-Québec’s LogisVert list (re-read Oct 26, 2026). No 9,000 is on it: their cooling is under 12,000 BTU/h.
At 9,000, the mini cassette gives the most heat at -8 °C (9,700 BTU/h) and the best SEER2 (22.00). None of the three has a LogisVert amount.
At 12,000, the mini cassette leads at -8 °C (10,700 BTU/h) and gets the most ($1,284). The 12,000 console is certified at 10,200 BTU/h in cooling: no amount.
At 18,000, the Slim Duct leads at -8 °C (16,200 BTU/h) and gets the most ($1,944); the mini cassette keeps the best SEER2 (20.50).

Under 12,000 BTU/h: below the LogisVert minimum.
July 8, 2027
For installations completed on or after November 26, 2025, the unit must be ENERGY STAR certified.
The outdoor unit needs a nominal cooling capacity of at least 12,000 BTU/h.
Apply no later than nine months after installation. The grant never exceeds 100% of the pre-tax cost.
The amount follows the installed combination, outdoor and indoor, as listed under its AHRI number.

The slim duct, in six claims.
True or false? Each card flips to its source.
Samsung ships a remote with the Slim Duct.
The box holds a 1.4 m Wi-Fi wire.
The 18,000 is taller than the 12,000.
Its indoor fan is the most powerful of Samsung’s three CAC units.
In a very humid ceiling, Samsung asks for thicker insulation.
The 9,000 is not cold-climate certified.
These topics have their own page, so we don’t repeat them here.
What people ask about the Samsung slim duct.
Above a ceiling: a drop ceiling, a bulkhead or a closet, at least 2.2 m off the floor. Air goes through a short duct to one room’s grille.
199 mm (7 13/16 in) for all three sizes, per Samsung, which also wants at least 20 mm between the unit and the ceiling: count on 219 mm. The 18,000 is wider, 1,100 mm instead of 900. We measure the space during the visit.
A slim duct serves a single room through short ducts: that is what Samsung’s installation manual specifies. A Hylex central system uses the whole house’s duct network.
Down to -25 °C (-13 °F), per Samsung, with high heating capacity at -20 °C (-4 °F). At -25 °C, NEEP lists up to 6,700, 7,000 and 15,400 BTU/h for the 9,000, 12,000 and 18,000.
Yes, built in: it lifts water up to 750 mm (29.5 in), with a check valve and a float switch that stops the unit if the water rises too high. The drain route follows the drawing in Samsung’s manual: we confirm it at install and test the pump in cooling.
No. Samsung intends it for free-air discharge or a duct serving one room only. For two rooms, we plan two units or an FJM Premium multi-zone, where the Slim Duct can be one of the heads.
Only if a refrigerant leak detection system is installed, per Samsung’s manual. On the Slim Duct, the
Yes: Samsung lists it among the heads compatible with FJM Premium multi-zone. The LogisVert amount then goes to the system. We confirm the combination in the quote.
Samsung’s submittals list it as built in, and the box holds a 1,400 mm Wi-Fi wire; the Slim Duct web page still mentions an adapter sold separately. We confirm it for your unit in the quote.
No. Hydro-Québec excludes indoor units and ducts installed outside the insulation envelope, for example in the attic or roof space. We place the unit on the heated side of the house, and check it during the visit.
Under drop tiles, no: a tile lifts out. Under drywall, Samsung’s manual asks for a 500 mm hatch B if there is more than 50 cm above, and two hatches, A (the unit’s width plus 100 mm) and B, if there is less.
The installer, at start-up. Samsung sets five ranges between 0.01 and 0.24 in. WC, 0.10 as standard, and the code is entered from the main wired control. The Slim Duct has no automatic airflow setting.
No question matches. Call us: 514 316-2973.
