DRA3H28M1A

Outdoor unit

One compressor for the whole house. It supplies up to 3 heads and modulates from 8,400 to 27,200 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.

05 · The series

09 · LogisVert grant

A grant you can calculate, not guess.

25,600 BTU/h÷ 1,000 ×$120=$3,072

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 210568214). 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.

22,6 SEER2 et deux têtes à placer sans défigurer une maison à étages

Un sous-sol qui reste froid alors que l'étage est confortable révèle presque toujours le même déséquilibre : le chauffage a été pensé pour les pièces de vie et le reste suit comme il peut. À Rivière-des-Prairies, c'est souvent un technicien venu pour un entretien qui annonce la fin de vie du système et ouvre la discussion. La Thermopompe 2-Zones DURASTAR Sirius Heat | 28 000 BTU - R410A permet de reprendre le problème par les deux bouts, une tête au sous-sol et une tête à l'étage, sans multiplier les appareils visibles.

Le relevé des cotes certifiées

  • Rendement saisonnier : 22,6 SEER2, 11,8 EER2 et 9,8 HSPF2
  • À -8 °C : 25 600 BTU/h, COP de 2,30
  • À -15 °C : 25 000 BTU/h, COP de 1,80
  • Homologation ENERGY STAR, ID ENERGY STAR 2410635, désignation climat froid, chauffage jusqu'à -30 °C

Le rendement saisonnier de 22,6 SEER2 est ce qui distingue cet ensemble : c'est la cote d'été, celle qui pèse sur la facture de juin à septembre, quand le sous-sol sert de refuge et que l'étage doit être rafraîchi la nuit. Ces données proviennent du certificat AHRI 210568214, publié par le NEEP.

Une tête au sous-sol, une tête à l'étage

Les 28 000 BTU/h du condenseur DRA3H28M1A se partagent entre les deux têtes selon la demande de chacune. Un sous-sol peu occupé peut rester à basse consigne tout l'hiver sans empêcher l'étage de chauffer normalement, et couper une zone n'arrête jamais l'autre. Les têtes se choisissent parmi DRAC18F1A, DRAC24F1A, DRAD12F1A, DRAD18F1A, DRAL12F1A, DRAM18F1A, DRAM24F1A et les autres modèles publiés par DuraStar ; le châssis accepte jusqu'à 3 zones.

La subvention LogisVert de 3 072 $

Cet ensemble est admissible au programme LogisVert pour 3 072 $ pour un propriétaire d'une habitation existante, sous l'ID ENERGY STAR 2410635. 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. Nous validons l'admissibilité avant la signature et montons le dossier ; des options de financement couvrent le solde.

Le parcours des goulottes, de la cour au sous-sol

Calibrer la goulotte avant de percer

Deux paires de lignes frigorifiques, deux drains et deux câbles de commande partent du condenseur. Regroupés sur la même façade, ils demandent une goulotte plus large qu'un appareil seul, et c'est ce calibre qui décide de l'allure finale du mur. Nous traçons le parcours avant le premier percement plutôt que de l'improviser tronçon par tronçon. Nos installations sont entièrement apparentes, sans travaux à l'intérieur des murs, avec un recouvrement de finition sur les portions vues de la rue.

La descente vers le sous-sol

La tête du sous-sol est la plus délicate à raccorder : le drain ne peut pas toujours s'écouler par gravité et la ligne doit franchir la dalle ou ressortir par la margelle. Le condenseur mesure 37,24 x 16,12 x 31,89 pouces et s'annonce à 63 dB(A) ; il se pose au-dessus de la ligne de neige, en gardant de la distance avec les fenêtres de chambre, y compris celles des voisins.

Le circuit de 40 A et les réactions normales

L'alimentation se fait en 220 V, avec un MCA de 25 A, un disjoncteur de 40 A et un circuit dédié ; le calcul de charge précède toujours la proposition. Une fois en service, l'appareil se manifeste de façon prévisible.

  • De la vapeur blanche sort du condenseur pendant le dégivrage.
  • Un délai de trois minutes au redémarrage protège le compresseur.
  • Le réfrigérant siffle brièvement quand la seconde zone se met en marche.
  • Le chauffage cesse sous -30 °C.

Une odeur de brûlé, un disjoncteur qui saute ou de l'eau qui coule à l'intérieur sortent de ce cadre : on arrête l'appareil et on appelle le service.

AirGreen, du chiffrage à l'entretien

Les filtres se rincent aux deux semaines et un entretien CVAC annuel couvre serpentins, condensat et raccords électriques ; un sous-sol poussiéreux justifie souvent notre service de nettoyage en complément. AirGreen est une entreprise familiale active depuis plus de quinze ans à Montréal, Laval, Longueuil, sur la Rive-Nord et sur la Rive-Sud, avec les licences RBQ en ventilation, en réfrigération et en électricité.

Réservez votre estimation gratuite pour la Thermopompe 2-Zones DURASTAR Sirius Heat | 28 000 BTU - R410A. Nous traçons la goulotte avant le premier percement, réglons le drainage du sous-sol et confirmons le montant LogisVert de 3 072 $.

Garantie : 10 ans sur le compresseur, 10 ans sur les pièces et 6 ans sur la main-d’œuvre, directement du distributeur.

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: 25,600 BTU/h at −8 °C, 25,000 at −15 °C.

How many heads can I connect?

Up to 3 on this outdoor unit. This product is configured for 2 heads.

How much is the LogisVert grant?

$3,072 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 2410635. 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, 63 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.
