Which Hylex replaces your electric furnace?

Pick your options to see the models, the AHRI number, the heat at -8 °C, the LogisVert amount when there is one, and what to plan for.

1Which range?
2What capacity?

Capacity is worked out during the visit, from the house and your ducts. Samsung recommends a two-stage thermostat.

For all: heating down to -25 °C per Samsung; MXD-U001XN control unit required, sold separately.

02 · Electric furnace

Electric furnace: the HH unit takes its place.

The Hylex air handler takes the electric furnace’s place, on your ducts. If you need backup heat, the heat kit installs inside the HH unit.

HHThe Hylex air handler

Three cabinet widths: 15 in · 18 1/2 in · 21 7/8 in. R-454B detector and mitigation built in, per Samsung. A 5 to 20 kW heat kit can go inside.

A gas, oil or propane furnace? It can stay: see the add-on.

03 · Upright, upside down or on its side

Upflow, downflow or horizontal: where does your HH unit go?

Your electric furnace blew one way. The HH unit can blow four ways, each with its own rules. Turn it.

1/2 in

Upflow

Air comes in at the bottom and out the top. The unit is supported from below only, on a solid floor or a field-built frame, per Samsung. It can also go in a closet whose false floor serves as the return plenum.

Downflow

It takes Samsung’s downflow conversion kit (by cabinet width: ), and the fan moves to speed 5.

Horizontal, left

The unit lies on its side, air goes out to the left. Samsung calls for a 1/2 in pitch toward the drain.

Horizontal, right

Air goes out to the right. This way, the drain pan has to move, per Samsung. Same 1/2 in pitch toward the drain.

Over a finished room, Samsung requires a secondary pan, drained to the outside.

In the attic

Samsung calls for an auxiliary pan in an attic or above a finished ceiling. And Hydro-Québec excludes from LogisVert any indoor unit or ducts outside the insulation envelope, such as in the attic.

Samsung’s manual says some models ship upflow-only, without naming them. The submittals give all four positions to every HH unit. We confirm the position with your unit’s rating plate.

A curious fact: three HH widths, three downflow kits. HA00DA0H1 for 15 in, HA00DB0H1 for 18 1/2 in, HA00DC0H1 for 21 7/8 in. Simplified illustration.

04 · Heat kits

Which heat kit fits which unit?

The Hylex HH unit can take an optional electric heat kit for backup. The sizes allowed change with the model: pick your Hylex, then a kit.

Your Hylex
Heat kit

Samsung makes five kits, 5 to 20 kW. Greyed-out sizes are not listed in Samsung’s submittal for the selected HH unit.

Source: Samsung Hylex submittals with HH unit (04072026), accessories p. 5, re-read Oct. 26, 2026; manual 679608-01 (10 kW downflow restriction). Brochure 02.2026-V2 lists 7.5 kW for HA07E0CH1; the submittal, 7 kW. Conversion: 1 kW = 3,412 BTU/h (NIST).

05 · No cold blast

During defrost, the fan stops. Here’s why.

In cold weather, the outdoor unit sometimes has to defrost. Samsung built in fan settings so you don’t feel cold air. Watch one cycle.

Your room

Cold-air prevention option: the coil warms up before the fan starts.Option off: the fan starts right away, with the coil still cold.

The fan turns, warm air rises in the ducts.

The outdoor unit defrosts. The fan stops so it doesn’t blow cold air and, per Samsung, to reduce the need for heat kits.

The fan restarts after a delay. Samsung provides adjustable delays for defrost and cold-air prevention.

A curious fact: Samsung says it outright. Stopping the fan during defrost is there to “reduce the need of electric heat kits”. Illustration: Samsung doesn’t publish defrost length or frequency in the documents we checked. The control unit manual also says the fan stop is disabled if low pressure drops to 14 psi or lower during defrost.

Source: Samsung, MXD-U001XN description in the AC048FCUPCG + HC60MBC021H1 system submittal (05052026), re-read Oct. 26, 2026; MXD-U001XN manual (DB68-13653A), p. 26 (14 psi). The control unit is the same on every Hylex.

06 · Your ducts slow the air

Your HH unit’s airflow, by duct resistance.

Samsung publishes each HH unit’s airflow by duct resistance, from 0.1 to 1.0 in of water column. Slide the resistance: the airflow follows Samsung’s table.

0.10.61.00.30 rated
 CFMairflow, speed 3 (factory setting)

Speed 3, factory setting, dry coil, filter in place. Samsung allows other speeds. The table is shown as printed, quirks included (586 then 588 CFM on the HH24MCAC11H1). A curious fact: from 0.1 to 1.0 in, the HH36MCBC11H1 keeps 83% of its airflow; the HH60MBCC11H1, 61%. Airflow per ton: AirGreen calculation.

Source: Samsung HH unit manual (679608-01), Table 1, re-read Oct. 26, 2026; submittals with HH unit (04072026), p. 3: 0.30 in rated, 0.1 to 1.0 in range. Conversion: 1 in of water = 249.09 Pa (NIST SP 811).

07 · Plan for

With the HH unit: the ACU, a filter, and a heat kit if needed.

The leak detector is already inside the HH unit. Plan for: the MXD-U001XN, a field-supplied filter and, if needed, a 5 to 20 kW heat kit on 1 or 2 circuits.

AlwaysThe MXD-U001XN control unit

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

AlwaysA filter, field-supplied

12 × 20, 16 × 20 or 18 × 25 in depending on the model. Samsung requires a filter listed as a “Class 2 furnace air filter”.

If neededA heat kit

5 to 20 kW, fed by 1 or 2 circuits depending on the kit. For 15 and 20 kW, the HA15B0CH1 single-point breaker kit is offered as an option.

Already thereThe leak detector

Built into the HH unit with its mitigation: no HA00A00203H1 controller here.

08 · R-454B safety

If refrigerant leaks, here is what the unit does.

R-454B is classified A2L: lower flammability. The Hylex HH unit has its detector and mitigation built in. Here is the sequence its manual describes.

Upper floorBasementHylex air handler (HH)Built-in detectorR-454B, always poweredThermostat cut offCompressor stoppedDucts purged7 minmore blower time,once the level drops

Illustration. Source: Samsung HH unit installation manual (679608-01, March 2026), re-read Oct. 26, 2026. Class A2L: burning velocity of 10 cm/s or less (ASHRAE 34). Per UL, mitigation must start within 15 seconds, at 25% of the lower flammability limit.

09 · R-454B and minimum area

R-454B charge and minimum floor area: where does your Hylex sit?

The HH manual ties the refrigerant charge to a minimum conditioned area. Pick your Hylex: we do the math with Samsung’s table.

10 × 10 ft

It’s a manufacturer safety rule for R-454B, classed A2L by ASHRAE. Samsung’s table doesn’t say whether to interpolate, so we show both readings. Altitude factor: 1.0 up to 600 m, per Samsung; Montréal (City Hall) sits at 20 m. The manual excerpts we read don’t define conditioned area, so we confirm it at the visit. A curious fact: the table follows 15 sq ft per pound, from 3 lb (45 sq ft) to 30 lb (450 sq ft).

10 · Hydro-Québec LogisVert

With the HH unit, $1,980 to $4,680 in Premium.

The same amount as the Hylex central: it is the same system, with the same AHRI number. With Samsung indoor units, the Standard is not ENERGY STAR certified. Pick a system to see the math.

16 · Frequently asked questions

What people ask about the Hylex “furnace”.

A heat pump. The HH unit takes the electric furnace’s place on your ducts, and the Hylex outdoor unit does the heat-pump work. Without a heat kit, the HH unit has no electric resistance heat.

A field-supplied filter: 12 × 20, 16 × 20 or 18 × 25 in depending on the model. Samsung requires a filter listed as a “Class 2 furnace air filter”.

Per Samsung’s submittals: 5, 7 or 10 kW on the 2-ton units; 5 to 15 kW at 3 tons; 5 to 20 kW on the Standard 4-ton; 7 to 20 kW on the Standard 5-ton and the Premium 4- and 5-ton.

They are the same systems, with the same AHRI numbers. We show them here too for people looking to replace an electric furnace.

Yes, per Samsung, on a false floor that serves as the return plenum. Keep 24 in clear in front for service.
