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.

05 · The series

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.

Cinq demandes différentes sur un même compresseur, qui suit la somme et non le maximum

Une maison ancestrale de Candiac rénovée pièce par pièce n'a pas deux pièces comparables : la cuisine refaite est étanche, la chambre du fond a gardé ses fenêtres d'origine, et le salon se situe entre les deux. Chauffer un tel bâtiment à une seule consigne revient à surchauffer les pièces neuves pour rendre les anciennes habitables, et la facture d'hiver le rappelle. La Thermopompe 5-Zones DURASTAR Sirius Heat | 55 000 BTU - R410A fait l'inverse : chaque tête demande ce dont sa pièce a besoin.

L'ensemble affiche 20,0 SEER2, 10,5 EER2 et 9,5 HSPF2. Il est homologué ENERGY STAR avec la désignation climat froid sous l'ID ENERGY STAR 2410630, chauffe jusqu'à -30 °C et donne droit à une subvention LogisVert de 4 176 $.

Le certificat, et les deux températures qu'il mesure

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, avec un COP de 1,80, correspond aux journées où une maison ancestrale perd le plus par ses murs d'origine. Ces valeurs proviennent du certificat AHRI 210568223, publié par le NEEP.

  • Cotes saisonnières : 20,0 SEER2, 10,5 EER2, 9,5 HSPF2
  • Limite de chauffage inscrite : -30 °C
  • Unité extérieure : 37,48 x 16,34 x 52,48 pouces, 61 dB(A)
  • Tête de référence publiée : 379 PCM, de 36 à 43 dB(A), 22,44 x 22,44 x 10,24 pouces

Ce que la modulation change quand une seule pièce demande

Quand quatre pièces sont à leur consigne et qu'une seule appelle du chauffage, le compresseur ne repart pas à pleine charge : il travaille à la hauteur de cette demande unique. Les cinq zones se partagent la capacité du condenseur DRA5H55M1A, et cette souplesse évite les cycles courts et les écarts d'une porte à l'autre. Les valeurs intérieures publiées décrivent une tête de référence, pas les cinq appareils retenus parmi les ensembles compatibles comme DRAS12F1A, DRAL18F1A ou DRAM24F1A.

L'aide LogisVert inscrite pour ce format

Le système figure sur la liste du programme LogisVert d'Hydro-Québec, avec 4 176 $ pour un propriétaire d'une habitation existante, selon la liste en vigueur à la date d'installation, et une aide bonifiée s'applique à certains immeubles à logements multiples. Nous confirmons l'admissibilité avant la signature et préparons les pièces du dossier : facture détaillée, numéros de modèle intérieur et extérieur, preuve de paiement.

Candiac : alimenter cinq zones sans toucher à la maçonnerie d'origine

Un disjoncteur de 60 A et le panneau d'une maison ancestrale

La fiche inscrit 220 V, un MCA de 40 A et un disjoncteur de 60 A sur un circuit dédié. C'est un calibre conséquent, et les maisons anciennes rénovées par étapes ont souvent gardé leur entrée d'origine. Nous reprenons le calcul de charge avec le panneau devant nous et annonçons toute mise à niveau avant la signature plutôt qu'au milieu du chantier.

Le condenseur vertical, posé hors du dégagement des murs anciens

Avec ses 37,48 x 16,34 x 52,48 pouces, l'unité extérieure occupe peu de surface au sol mais demande un dégagement franc devant la sortie d'air. Elle se pose sur un support ancré dans la structure ou sur une base au sol selon le parement, au-dessus de la ligne de neige, avec l'élément chauffant de bac de série. Mesurée à 61 dB(A), elle s'éloigne des fenêtres de chambre.

Les lignes montées en apparent, sans ouvrir les murs de plâtre

Dans une maison ancestrale, ouvrir un mur de plâtre sur lattes coûte plus cher que tout le reste de la pose. Chaque tête reçoit donc son jeu de lignes en goulotte, entièrement apparent, sans travaux à l'intérieur des murs, avec un recouvrement de finition. Une zone fermée, dans une pièce qu'on n'occupe plus l'hiver, n'arrête pas les quatre autres.

AirGreen, dans une maison rénovée par étapes

Entreprise familiale depuis plus de quinze ans, nous couvrons Montréal, Laval, Longueuil, la Rive-Nord et la Rive-Sud, avec les licences RBQ en ventilation, en réfrigération et en électricité et une assurance responsabilité de 5 000 000 $. Nos réalisations comprennent des bâtiments anciens de ce type, et notre service de réparation prend le relais si un code d'erreur persiste.

Réservez votre estimation gratuite pour la Thermopompe 5-Zones DURASTAR Sirius Heat | 55 000 BTU - R410A. Nous relevons chaque pièce selon son état de rénovation, vérifions la capacité du panneau pour un circuit de 60 A et traçons les goulottes sans ouvrir vos murs.

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 5 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.
