Samsung Hylex central heat pumps · updated October 8, 2026

Hylex: the Samsung central heat pump that uses your ducts.

Hylex replaces central air and heats through your ducts, using R-454B refrigerant, down to -25 °C outside, per Samsung. Two ways to install it: with its air handler, in place of an electric furnace, or as an “add-on” on the furnace you keep. With its Samsung indoor units, the Premium is ENERGY STAR cold-climate certified (except the 5-ton add-on): LogisVert from $1,980 to $4,680 as a central system, $1,812 and $2,592 as an add-on.

02 · Central or add-on

Two ways to install a Hylex.

Replacing an electric furnace? The HH unit takes its place. Keeping your furnace? We add a coil to it.

HHCentral: the air handler

The Hylex multi-position indoor unit (HH series) takes the place of an electric furnace and uses your ducts. Built-in R-454B leak detector and mitigation control, per Samsung. Optional 5 to 20 kW electric heat kits.

HCAdd-on: the coil on your furnace

A Hylex cased A-coil (HC series) goes on the furnace you keep. The heat pump heats and cools; the furnace takes over when needed. We do not touch the burner or the gas or oil supply.

03 · How it works

On your ducts, from basement to living room.

The Hylex outside, an air handler or a coil on the furnace inside, and your ducts to deliver. Switch between heating and cooling, and between the two ways to install it.

Illustration. Sources: Samsung Hylex R-454B submittals and manuals; brochure HYLEXBR 02.2026-V2 (“only 2 wires”, liquid line needs no insulation).

04 · Premium or Standard

Premium: more efficient, and the only one of the two eligible for LogisVert.

Same tonnages, same R-454B, same -25 °C. Premium is more efficient, keeps full capacity lower in 2 and 3 tons and gets LogisVert, except the 5-ton add-on.

05 · The ton, explained

A “ton” is melting ice.

Central heat pumps come in 2 to 5 tons, but tons of what? Slide: we translate into BTU/h, kilowatts and ice.

Tonnage: 3 tons

The word comes from ice. Melting a short ton of ice (2,000 lb) takes 286,000 BTU. Spread over 24 hours, that is 11,917 BTU/h, rounded to 12,000: the ton of refrigeration.

Your tonnage, translated

36,000 BTU/h

In kilowatts10.6 kW

Ice melted in 24 h6,000 lb · 2,722 kg

Hylex comes in 2, 3, 4 and 5 tons. The right tonnage comes from a load calculation of the house, not from the size of the old unit: we do it during the visit.

Source: Natural Resources Canada (1 ton = 3.5 kW = 12,000 BTU/h); ACCA, “A Little History Behind Tons”, 2015 (286,000 BTU, 11,917 BTU/h); NIST SP 811 (1 kW = 3,412.14 BTU/h).

06 · To plan for

What Samsung requires around the Hylex.

Nothing hidden: these parts are in the quote when your install needs them.

The MXD-U001XN control unit

Required by Samsung, even with its own indoor unit, and sold separately. We include it in the quote.

A 24 V thermostat

Hylex works with a standard 24 V thermostat. Samsung recommends a two-stage thermostat.

Electric heat kits, optional

In a central install, on the HH unit: 5 to 20 kW depending on the model (up to 10 kW on 2-ton units, 15 kW on 3-ton units). For 15 and 20 kW, Samsung offers the HA15B0CH1 single-point breaker kit.

The A2L mitigation controller

Required with an HC coil (add-on), per Samsung: HA00A00203H1. The HH unit already has its own.

07 · Sound

Outside, between 50 and 58 dB(A).

The sound level of each Hylex, in cooling and heating. The difference comes mostly from tonnage.

Samsung compares this with 68 dB(A) or more for traditional unitary equipment, without stating the measuring distance. 50 dB(A) is the 2-ton cooling value.

Three levels, automatic or triggered by an external contact (MIM-B14U module), per Samsung.

12 · True or false

The Hylex, in six claims.

True or false? Each card flips to its source.

0/ 6

Pick True or False: the card flips to show the answer and its source.

The Premium has an inverter compressor; the Standard, a two-stage compressor.

Between the outdoor and indoor units, two control wires are enough.

The Hylex liquid line needs no insulation.

The Hylex can be 300 ft from its indoor unit.

Kilogram for kilogram, the Hylex’s R-454B has less than a quarter of the warming potential of R-410A.

At Samsung, Hylex once stood for “Hybrid Flexible Single”.

13 · Frequently asked questions

What people ask about Hylex central systems.

In a central install, the Hylex air handler (HH) replaces the electric furnace. In an add-on, a Hylex coil (HC) goes on the furnace you keep, and the furnace takes over when needed.

With the Samsung indoor unit, the Hylex Standard is not ENERGY STAR certified. Since November 26, 2025, Hydro-Québec requires that certification.

A standard 24 V thermostat, ideally two-stage per Samsung. The MXD-U001XN control unit is required.

Down to -25 °C (-13 °F) for the whole range. Premium 2 and 3 tons keep 100% of rated capacity down to -20 °C; the others down to -10 °C, per the Samsung spec sheets (except Standard 5 tons, not stated).

No. Hydro-Québec’s guide excludes replacing a single coil or a single indoor or outdoor unit. The amount follows the complete combination installed, under its AHRI number.

In a central install, Samsung offers 5 to 20 kW heat kits for the HH unit. In an add-on, your furnace takes over. We discuss it during the visit.

The HH unit has its own leak detector and mitigation control. With an HC coil, Samsung requires the HA00A00203H1 mitigation controller.

No. In an add-on, we install the coil on the furnace and the heat pump outside; we do not touch the burner or the gas or oil supply.

Up to 10 years on compressor and parts if the system is registered with Samsung within 60 days. Conditions apply. We register it for you.

Hydro-Québec excludes indoor units and ducts installed outside the insulation envelope, for example in the attic or roof space. We look at your duct route during the visit.
