DRA5H55M1A

Outdoor unit

One compressor for the whole house. It supplies up to 5 heads and modulates from 20,000 to 45,000 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.

34,800 BTU/h÷ 1,000 ×$120=$4,176

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 210568223). 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.

Deux logements d'un triplex à convertir, sans imposer le bruit au troisième

Dans un triplex de Montréal, la conversion se fait rarement d'un coup. Le propriétaire traite d'abord les deux logements dont l'appareil actuel siffle et vibre au point qu'on l'entend depuis la cour. Reste à poser une seule unité extérieure dans une cour étroite sans imposer ce bruit au troisième logement. La Thermopompe 2-Zones DURASTAR Sirius Heat | 55 000 BTU - R410A couvre exactement ce cas : un condenseur, deux têtes commandées séparément.

Les valeurs publiées pour le condenseur DRA5H55M1A

  • 20,0 SEER2, 10,5 EER2 et 9,5 HSPF2
  • À -8 °C : 34 800 BTU/h, COP de 2,4
  • À -15 °C : 45 500 BTU/h, COP de 1,8
  • Chauffage jusqu'à -30 °C, désignation climat froid

Le certificat inscrit 34 800 BTU/h à -8 °C et 45 500 BTU/h à -15 °C. Les deux points sont mesurés séparément ; nous reprenons chacun tel qu'il est publié. Celui de -15 °C compte ici : à cette température, deux logements complets tiennent sur le même compresseur. Ces valeurs proviennent du certificat AHRI 210568223, publié par le NEEP.

Le bruit se traite à la source, pas au ressenti

Le condenseur produit 61 dB(A), un chiffre qui se gère par la position : au fond de la cour, contre un mur aveugle, loin des fenêtres de chambre du troisième logement. À l'intérieur, la fiche publie 36 dB(A) en vitesse basse, 43 dB(A) en vitesse haute et 379 PCM pour l'appareil de référence ; chaque tête de la liste a ses propres cotes. Un appareil qui grogne relève de notre service de réparation.

Les 4 176 $ versés par LogisVert

Le système est inscrit au programme LogisVert d'Hydro-Québec : 4 176 $ pour un propriétaire d'une habitation existante, sous l'ID ENERGY STAR 2410630, selon la liste en vigueur à la date d'installation. Une aide bonifiée s'applique à certains immeubles à logements multiples, ce qui vise directement un triplex. Nos options de financement couvrent l'écart jusqu'au versement.

Un condenseur, deux compteurs : le raccordement électrique d'un triplex

Comment les 55 000 BTU/h se partagent entre deux têtes

Les deux appareils intérieurs se prennent dans la liste de compatibilité de DuraStar, qui mêle cassettes, gainables, consoles et têtes murales, du DRAL09F1A au DRAM24F1A. Chaque logement commande le sien, et couper une zone ne coupe pas l'autre : le compresseur module pour celui qui reste en demande. La capacité disponible est celle du condenseur, jamais la somme des deux têtes. Ce condenseur est catalogué jusqu'à 5 zones ; la configuration vendue ici en dessert 2.

L'unité extérieure dans une cour de triplex

Le condenseur mesure 37,48 x 16,34 x 52,48 pouces. Dans une cour étroite, il se pose sur une base au sol stable ou sur un support ancré dans la structure, jamais dans le seul parement, et toujours au-dessus de la ligne de neige. Les lignes montent ensuite vers chaque logement, une paire par tête, regroupées sur un même trajet. Nos installations sont entièrement apparentes, sans travaux à l'intérieur des murs.

Le compteur qui porte le circuit

L'appareil demande du 220 V, un MCA de 40 A et un disjoncteur de 60 A sur un circuit dédié. Dans un triplex, il faut établir quel compteur porte ce circuit, puisqu'un seul condenseur dessert deux logements : en général celui du propriétaire, avec l'accord écrit des occupants. Une entrée de 100 A déjà chargée de plinthes ne le reçoit pas sans calcul de charge.

  • Le dégivrage libère de la vapeur blanche au condenseur par temps humide.
  • Un délai de trois minutes au redémarrage protège le compresseur.
  • Un bref sifflement du réfrigérant accompagne le passage d'une zone à l'autre.

Une odeur de brûlé, un disjoncteur qui saute, un code d'erreur persistant ou de l'eau à l'intérieur imposent l'arrêt et un appel au service. Les filtres des deux têtes se nettoient aux deux semaines, et l'entretien CVAC annuel couvre les serpentins, le condensat et les raccords électriques.

AirGreen, quand le chantier touche des logements occupés

Entreprise familiale de Montréal depuis plus de quinze ans, AirGreen intervient aussi à Laval, à Longueuil, sur la Rive-Nord et sur la Rive-Sud. Nous détenons les licences RBQ en ventilation, en réfrigération et en électricité, et une assurance responsabilité de 5 000 000 $. Les accès se conviennent logement par logement avant la date retenue.

18 · 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: 34,800 BTU/h at −8 °C, 45,500 at −15 °C.

How many heads can I connect?

Up to 5 on this outdoor unit. This product is configured for 2 heads.

How much is the LogisVert grant?

$4,176 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 2410630. 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, 61 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.
