Your electric furnace, replaced by a Samsung Hylex central heat pump.
Our Samsung “electric furnaces” are complete Hylex systems: the multi-position air handler (HH series), which takes the place of the electric furnace, with its outdoor unit. Same AHRI numbers as our central heat pumps. Heating down to -25 °C, optional 5 to 20 kW heat kits, LogisVert from $1,980 to $4,680 with the Premium.
- Cabinets 15, 18 1/2 or 21 7/8 in wide
- Detector and mitigation built in
- 5-speed ECM blower
Optional Samsung heat kits for the HH unit, for the coldest days.
Samsung submittals with HH unit (04072026).
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.
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;

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.
Three cabinet widths: 15 in · 18 1/2 in · 21 7/8 in.
A gas, oil or propane furnace? It can stay: see the add-on.
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.
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.
On 24,000 BTU/h units, no 10 kW heat kit with the downflow kit, per Samsung.
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.
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.

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

For 15 and 20 kW, Samsung offers the
On 24,000 BTU/h units like this one, Samsung rules out the 10 kW kit in the downflow position.
Without a kit, the HH unit has no built-in backup: we look at how to cover the coldest days during the visit.

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.
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.

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.
