DRA5H48M1A

Outdoor unit

One compressor for the whole house. It supplies up to 5 heads and modulates from 13,000 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.

39,000 BTU/h÷ 1,000 ×$120=$4,680

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 210568220). 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 chalet habité à l'année réclame autant de chauffage en bas que sous les combles

Un chalet de Laval occupé à l'année depuis la pandémie ne se comporte plus comme un chalet. La toiture refaite a changé l'ordre des priorités : l'enveloppe du haut tient enfin, et ce sont le rez-de-chaussée ouvert et les deux chambres mansardées qui commandent maintenant la dépense. La Thermopompe 4-Zones DURASTAR Sirius Heat | 48 000 BTU - R410A permet de traiter ces pièces séparément, avec une seule unité extérieure et quatre têtes réglées chacune à sa consigne, plutôt qu'un appareil unique qui surchaufferait le bas pour atteindre le haut.

Deux points de mesure, deux températures

Le certificat inscrit 39 000 BTU/h à -8 °C et 45 000 BTU/h à -15 °C. Les deux points sont mesurés séparément ; nous reprenons chacun tel qu'il est publié. Celui de -15 °C parle le plus pour un bâtiment occupé tout l'hiver : avec un COP de 2,00, le système restitue deux fois plus de chaleur que l'électricité consommée.

  • Cotes saisonnières : 21,2 SEER2, 11,0 EER2 et 10,0 HSPF2
  • COP de 2,50 au point de -8 °C
  • Homologué ENERGY STAR et désigné pour le climat froid
  • Limite de chauffage inscrite à -30 °C

Ces chiffres sont ceux du certificat AHRI 210568220, tels que publiés par le NEEP.

Répartir la capacité entre le rez-de-chaussée et les combles

Les 48 000 BTU/h nominaux ne se découpent pas en quatre parts identiques : ils forment une réserve commune dans laquelle chaque tête puise selon son format et sa consigne. Le rez-de-chaussée ouvert prend la plus grosse tête, les chambres mansardées de petites, et la quatrième zone la pièce transformée en bureau. Une toiture neuve fait baisser la demande du haut, et nous en tenons compte avant d'arrêter les formats.

LogisVert : 4 680 $ pour ce format de quatre zones

Le système figure sur la liste d'Hydro-Québec pour 4 680 $, sous l'ID ENERGY STAR 2410632, pour un propriétaire d'une habitation existante. 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 vérifions l'inscription avant la signature ; pour le solde, nos options de financement évitent d'attendre le versement de l'aide.

Arrêter le point d'appui du condenseur avant de percer quoi que ce soit

Un châssis de 52,48 po de haut sur un terrain de chalet

L'unité extérieure mesure 37,48 po x 16,34 po x 52,48 po et se tient à 65 dB(A). Cette hauteur écarte le support mural : nous partons d'une base au sol mise de niveau, au-dessus de la ligne de neige, avec un dégagement franc devant la grille. Le point d'appui se choisit loin des fenêtres de chambre, y compris celles des voisins, et à l'écart des descentes de toit. L'élément chauffant du bac de base et le revêtement anticorrosion sont de série.

Les quatre têtes, leurs lignes et le circuit de 60 A

Les valeurs intérieures publiées valent pour une unité de référence, pas pour les quatre têtes : 22,44 po x 22,44 po x 10,24 po, 379 pi³/min et 36 à 43 dB(A). Les vingt-trois modèles compatibles vont des DRAC09F1A et DRAL09F1A aux DRAM24F1A et DRAS12F1A. Chaque tête rejoint le condenseur par sa propre paire de lignes frigorifiques, et sous des combles refaits ce parcours se planifie tôt ; nos installations restent entièrement apparentes, sans travaux à l'intérieur des murs. Couper la zone des combles l'été ne prive pas le rez-de-chaussée. Le raccordement demande 220 V, un MCA de 40 A et un disjoncteur de 60 A sur un circuit dédié, ce qui est sérieux pour un bâtiment longtemps saisonnier resté sur une entrée de 100 A.

AirGreen, quand un bâtiment saisonnier passe à l'année

Nous refaisons le calcul de charge et annonçons toute mise à niveau du panneau avant la signature. Si un code persiste ou qu'une odeur de brûlé apparaît, coupez le système et appelez notre service de réparation. Entreprise familiale de Montréal depuis plus de quinze ans, titulaire des licences RBQ en ventilation, en réfrigération et en électricité et couverte par une assurance responsabilité de 5 000 000 $, AirGreen offre l'évaluation gratuite et la soumission écrite à Montréal, à Laval, à Longueuil, sur la Rive-Nord et sur la Rive-Sud. Avant de retenir quatre zones, nous vérifions si trois suffisent.

Réservez votre estimation gratuite pour la Thermopompe 4-Zones DURASTAR Sirius Heat | 48 000 BTU - R410A. Nous mesurons chaque pièce, arrêtons le point d'appui du condenseur et validons la capacité du panneau avant les travaux.

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: 39,000 BTU/h at −8 °C, 45,000 at −15 °C.

How many heads can I connect?

Up to 5 on this outdoor unit. This product is configured for 4 heads.

How much is the LogisVert grant?

$4,680 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 2410632. 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, 65 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.
