ARCOAIRE 5-zone heat pump · Updated October 29, 2026
Five rooms: only the biggest outdoor units keep up.
Five heads is the printed maximum for the 48,000 DLCMRA and the DLCMHB 48HH, now at the end of its series. We also sell the 48,000 and 55,000 D5CMHA as 5-zone, to be confirmed per size. Pick the unit and the temperature: you see its heat for the whole system and what that works out to per head, on average.

01 · Per head
Five heads on one unit: how much heat for each, on average?
System values come from NEEP or, for the DLCMRA, the 2018 catalogue. The per-head average is our calculation: the system value divided by five.

Heat per head, on average (our calculation)
Five 9,000 heads do not ask for the same thing as five 12,000 heads. The heads are chosen at the visit; the average helps compare the outdoor units.

DLCMRAH48EAK
48,000 BTU · 12 five-head combinations
In thousands of BTU/h, as printed in the 2018 catalogue, p. 48. Every 5-zone variant on our DLCMRA product page is in it. For the DLCMHB 48HH, there is no combination chart: we read one range per wall head in the 2024 catalogue (p. 21), in merged cells with no borders, and we confirm it before the quote. For the D5CMHA, no chart in the documents we hold.
03 · The line sets
Five line sets to run: the manufacturer’s limits.
The limits the manufacturer prints in its catalogues for the DLCMRA and the DLCMHB, and those on its web page for the D5CMHA. The total length adds up all five line sets. For the DLCMRA and the DLCMHB, the printed maximum height difference is the same whether the outdoor unit sits above or below the heads.

Did you know
Three things the manufacturer’s charts tell you.
Just 1
With five heads, only one combination takes a 24,000.
On the 48,000 DLCMRA: 9 + 9 + 9 + 9 + 24 (thousands of BTU/h). The other eleven use only 9,000 to 18,000 heads.
ARCOAIRE ductless catalogue 328-32-0499-00, May 2018, p. 48131%
The biggest combinations add up to 63,000 BTU/h of heads.
9 + 9 + 9 + 18 + 18 and 9 + 12 + 12 + 12 + 18: 131% of the 48,000 unit’s size (our calculation from the chart).
ARCOAIRE ductless catalogue 328-32-0499-00, May 2018, p. 48328 ft
Up to 100 m of total piping, for five heads.
That is the length printed for the 48,000 DLCMRA and the DLCMHB 48HH, with the farthest head at 115 ft (35 m).
Catalogue 328-32-0499-00, p. 46; catalogue DLS-001-AR-01, p. 4704 · Questions
What people ask us about 5-zone systems.
Five heads on one unit: is that reasonable?
The manufacturer prints five heads for the 48,000 DLCMRA and the 48HH; for the D5CMHA, it is a configuration we sell, to be confirmed per size. The more heads, the more the system’s heat is shared: compare the per-head average in the tool, and think of the rooms that need the most.
Why is the per-head average only a guide?
Because heat goes where it is called for. A north bedroom and a bathroom do not take the same share. The average helps compare units with each other, not size a room.
Why “not published” for some temperatures?
We only show values listed by NEEP or printed by the manufacturer. NEEP lists no -30 °C point for the DLCMHB 48HH, and the DLCMRA catalogue gives only a maximum at -15 °C.
And the 55,000 D5CMHA: how many heads at most?
The documents we hold state up to six indoor units for the family, with no maximum per size. We sell it up to 5 zones; the maximum per size is confirmed before any quote.
What about LogisVert?
It is indicative and taken from our product sheets: the DLCMRA has none on our sheets. Only Hydro-Québec confirms the amount granted.
How do you choose the five heads?
At the visit, room by room. Then we check the combination, the total length of the five line sets and where the outdoor unit goes.

Five rooms, a unit that keeps up.
We size each room, choose the five heads, then check the combination and the line-set lengths against the manufacturer’s documents. You get a quote with the system and its AHRI number when it has one.
