01 · Which size?

Four sizes out of five get the cold-climate rate.

Pick a size: model numbers, AHRI number, certified heat at -8 °C and the math at $120 per 1,000 BTU/h. The 9,000 stays under the 12,000 BTU/h minimum.

03 · Montreal winters

In January, at least 736 of 744 hours stay within its range.

The National Building Code sets Montreal’s 1% January design temperature at -26 °C: on average, only 8 January hours are colder. Max Heat still heats at -26 °C, and down to -30 °C per Samsung.

January has 744 hours. The Code ranks them: 19 are colder than -23 °C, 8 colder than -26 °C, on average. Max Heat still heats at those temperatures, with less output. Below -30 °C, its limit, it is 0.21 day a year on average; the record, -37.8 °C, dates from 1957: keep backup heat for nights like that.

04 · Cold climate, certified

Four ENERGY STAR cold-climate tests, five sizes that pass.

This certification is what moves LogisVert from $50 to $120 per 1,000 BTU/h. Pick a size: each needle shows the certified result, the yellow mark shows the bar.

And a controls test. ENERGY STAR requires these -15 °C results to be reached by the unit’s own controls, as they would run in your home.

This 70% compares certified heat at -15 °C (5 °F) with rated heat at 8.3 °C (47 °F). It is not the same measure as Samsung’s 100%, whose basis Samsung does not state. The 24,000: COP 2.22 at ENERGY STAR, 2.04 on Samsung’s submittal.

05 · Defrost

Why the outdoor unit doesn’t turn into a block of ice.

In cold, damp weather, frost builds on the outdoor coil. The Max Heat melts it with defrost cycles, and its factory base pan heater helps defrost water drain away without freezing, per Samsung.

Outdoor coil (fins)Base pan heater, standardWater drains awayIllustration: how defrost works

Simplified illustration. Base pan heater: Samsung Max Heat submittals (10072024A) and samsunghvac.com (“integral base pan heater to defrost and drain away water to avoid ice buildup”). Samsung also asks for at least 80 mm (3.14 in) between the bottom of the outdoor unit and the ground, and recommends raising it on a bracket fixed to a concrete pad (installation manual).

06 · The outdoor unit

At 15,000 and 18,000, Max Heat uses the next size up outside.

Same compressor type, but outside, the Max Heat 15,000 has the dimensions of the Standard 18,000, and the 18,000 those of the 24,000: more airflow, more refrigerant. At every size it has a factory base pan heater.

Drawn to scale from Samsung’s submittals. The fan spins faster when the listed airflow is higher. Yellow strip: base pan heater.

Same size outside (31 1/8 × 21 9/16 × 11 1/4 in). Max Heat weighs 1.8 lb more and has a factory base pan heater.

07 · Max Heat or Standard

At 24,000 BTU/h, Max Heat gets $1,620 more than Standard.

Max Heat is cold-climate certified: $120 per 1,000 BTU/h. Standard, ENERGY STAR without the cold-climate tier: $50. And Standard stops at -20.6 °C.

What Samsung does not publish
  • How to read its model numbers: Samsung writes them with wildcards (AR**DX…) and does not explain each character.
  • The test conditions behind the sound levels, and the sound at the middle fan speeds.
  • The remote control’s model number and the filter-cleaning interval (the owner’s manual is not on a Samsung site).

HSPF2 region V comes from NEEP: Samsung prints region IV only. The 24,000: COP at -15 °C is 2.22 at ENERGY STAR (certified record), 2.04 on the Samsung sheet.

11 · Cooling in winter

It still cools at -18 °C outside.

A room that overheats in winter, like a storefront or an equipment room, sometimes needs cooling while it’s freezing. Pick a month: we place Montréal’s average low on Max Heat’s range.

14 · Frequently asked questions

What people ask about the Max Heat.

Down to -30 °C (-22 °F) outside, per the Samsung submittal. Per the same submittal, it keeps 100% of its heating capacity down to -20 °C (-4 °F).

Per NEEP, read by AHRI number on Oct. 14, 2026, its maximum capacity at -30 °C ranges from 6,800 BTU/h (9,000 and 12,000) to 11,500 BTU/h (24,000).

Max Heat is ENERGY STAR cold-climate certified: Hydro-Québec gives $120 per 1,000 BTU/h of heat at -8 °C. Standard gets $50.

Yes. Our published installs show it on balconies, flat roofs and under stairs. Samsung asks for at least 700 mm (27.5 in) clear in front of the air outlet. As for weight, the outdoor unit runs from 71 lb (9,000 and 12,000) to 150.4 lb (18,000 and 24,000).

Both come from Samsung. The Max Heat submittals say 100% heating capacity at -20 °C (-4 °F); Samsung’s web page says 100% at -15 °C (5 °F). Both agree on heating down to -30 °C, with “high capacity”. Samsung does not say what this 100% is measured against. ENERGY STAR measures something else: certified heat at -15 °C compared with rated heat at 8.3 °C. For the 9,000, that is 8,500 of 11,000 BTU/h, or 77%.

Four bars: at least 70% of rated heat still there at -15 °C, a COP of at least 1.75 at -15 °C, an HSPF2 of at least 8.5 and a SEER2 of at least 15.2 for a ductless heat pump. All five Max Heat units pass, per their ENERGY STAR records.

Samsung puts the Max Heat 15,000 in an outdoor unit the size of the Standard 18,000, with more airflow and more refrigerant. Samsung gives no other explanation, nor the coil size.

Yes, in some cases. Since June 15, 2026, Hydro-Québec adds $100 per 1,000 BTU/h at -8 °C, for $220 in total, for an ENERGY STAR cold-climate wall unit installed in a multi-unit building located in an energy-poverty zone. This bonus cannot be combined with any other offer. Max Heat is a cold-climate wall unit; Standard is not.

Yes, down to -18 °C outside per Samsung’s submittal, if the room is between 16 and 32 °C. The Standard stops cooling below -10 °C.

No question matches. Call us: 514 316-2973.
