DRA4H36M1A

Outdoor unit

One compressor for the whole house. It supplies up to 4 heads and modulates from 10,000 to 35,200 BTU/h depending on what the rooms call for (NEEP).

03 · How it works

Turn rooms on and off. Watch the power being shared.

One outdoor unit supplies every head: when several rooms call at once, they share its capacity. Pick an outdoor temperature.

04 · My plan

Tell us your rooms. We tell you if this size is enough.

Pick the number of rooms and their size. The estimate targets a −15 °C day; it is a guide, the real calculation is done room by room at your home.

09 · LogisVert grant

A grant you can calculate, not guess.

35,000 BTU/h÷ 1,000 ×$120=$4,200

The capacity at −8 °C comes from Hydro-Québec’s list of October 1, 2026. $120 per 1,000 BTU/h is the rate for ENERGY STAR cold-climate heat pumps (guide v1.10).

Set for this system (AHRI 210568217). Another head combination (ducted, console) can change the AHRI number, and so the amount.
Cap: the grant never exceeds 100 % of the purchase and installation cost before taxes.
9 months after installation to apply; +5 % when two measures are in the same request.

Everything we have written about this system.

Un condenseur vertical dans la cour étroite d'un duplex, et deux logements à servir

Dans un duplex de Saint-Jérôme dont le logement du haut est loué, la cour est rarement grande et elle sert à tout le monde. Quand l'ancien appareil se met à vibrer contre le mur et qu'on l'entend depuis la galerie du locataire, le remplacement se décide vite, mais l'espace disponible, lui, ne change pas. La Thermopompe 2-Zones DURASTAR Sirius Heat | 36 000 BTU - R410A répond à cette contrainte par un condenseur vertical : il monte plutôt qu'il ne s'étale, et il dessert les deux logements depuis un seul point.

Les capacités inscrites au certificat

  • Rendement saisonnier : 20,0 SEER2, 12,5 EER2 et 9,7 HSPF2
  • À -8 °C : 35 000 BTU/h, COP de 2,35
  • À -15 °C : 36 000 BTU/h, COP de 1,90
  • Homologation ENERGY STAR, ID ENERGY STAR 2410628, désignation climat froid, chauffage jusqu'à -30 °C

Le certificat inscrit 35 000 BTU/h à -8 °C et 36 000 BTU/h à -15 °C. Les deux points sont mesurés séparément ; nous reprenons chacun tel qu'il est publié. Celui de -8 °C se traduit simplement : c'est la température où les deux logements chauffent ensemble, et 35 000 BTU/h y sont disponibles. Ces chiffres sont ceux du certificat AHRI 210568217, tels que publiés par le NEEP.

Deux logements, une seule emprise au sol

Le condenseur DRA4H36M1A mesure 37,48 x 16,34 x 52,48 pouces. Il est haut et étroit, ce qui libère la circulation dans une cour où il faut encore passer avec une souffleuse. Ses 36 000 BTU/h se partagent entre les deux têtes selon la demande de chaque logement, et un locataire qui coupe sa zone en octobre ne prive pas le rez-de-chaussée. Les têtes se choisissent parmi DRAC12F1A, DRAC18F1A, DRAD18F1A, DRAD24F1A, DRAM24F1A et les autres modèles publiés ; le châssis accepte jusqu'à 4 zones.

La subvention LogisVert de 4 200 $

Cet ensemble est inscrit au programme LogisVert pour 4 200 $ pour un propriétaire d'une habitation existante, sous l'ID ENERGY STAR 2410628. Le montant dépend de la liste en vigueur à la date d'installation, et une aide bonifiée s'applique à certains immeubles à logements multiples, ce qui concerne directement un duplex avec logement loué.

Un disjoncteur de 60 A dans un duplex : ce qui doit être vérifié avant tout

Le panneau qui portera le circuit

L'ensemble demande 220 V, un MCA de 40 A, un disjoncteur de 60 A et un circuit dédié. Dans un duplex, la question précède le calcul : le circuit part-il du panneau du propriétaire ou de celui du logement loué. Un seul compteur portera la consommation des deux zones, et cela se règle par écrit avant le chantier. Le calcul de charge décide ensuite si ce panneau accepte le calibre ; toute mise à niveau est annoncée avant la signature.

Les lignes vers les deux logements

Chaque tête reçoit sa paire de lignes frigorifiques, son drain et son câble de commande. L'un des deux parcours monte à l'étage le long du mur arrière. Le condenseur se pose au-dessus de la ligne de neige, à distance des fenêtres de chambre des deux logements et de celles des voisins. Nos installations sont entièrement apparentes, sans travaux à l'intérieur des murs, avec un recouvrement de finition sur les portions visibles depuis la rue.

Les bruits du condenseur et ce qui doit alerter

Voici ce qui est normal sur cet appareil, annoncé à 62 dB(A).

  • Le niveau sonore monte pendant le dégivrage, accompagné de vapeur blanche.
  • Un délai de trois minutes au redémarrage protège le compresseur.
  • Le réfrigérant siffle brièvement quand la seconde zone démarre.
  • Le chauffage cesse sous -30 °C.

Une vibration continue transmise au mur, une odeur de brûlé, un disjoncteur qui saute ou de l'eau à l'intérieur sont autre chose : on arrête l'appareil et on appelle notre service de réparation.

19 · Questions

What people ask us about multi-zone systems.

Can I heat one room and cool another at the same time?

No. On a multi-zone system like this one, every head works in the same mode, heating or cooling. Each room still keeps its own set temperature.

What happens when every room calls for heat?

They share the outdoor unit’s capacity: 35,000 BTU/h at −8 °C, 36,000 at −15 °C.

How many heads can I connect?

Up to 4 on this outdoor unit. This product is configured for 2 heads.

How much is the LogisVert grant?

$4,200 according to Hydro-Québec’s list of October 1, 2026. The grant never exceeds 100 % of the cost before taxes; apply within 9 months of installation.

Is it ENERGY STAR certified?

Yes, cold climate, ID 2410628. It also meets the ENERGY STAR Most Efficient criteria, according to the ENERGY STAR database.

Down to what temperature does it heat?

Down to −30 °C.

Is it noisy?

Indoors, the reference head goes down to 36 dB(A). Outdoors, 62 dB(A): we place the unit away from bedroom windows.

Why a multi-zone instead of several wall units?

One outdoor unit on the wall and one circuit. In return, the rooms share the capacity, and if the outdoor unit stops, every zone stops.

What does the warranty cover?

Our sheet lists 10 years on the compressor and 10 years on parts. AirGreen extended warranty: possible.

We measure every room, draw the line route and choose the right head for each zone. The on-site estimate is free and the quote arrives within 24 h.
