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 circuit au R-410A pour deux logements d'un triplex, et un troisième laissé intact

Dans un triplex de Deux-Montagnes, il arrive que seuls deux logements soient à convertir : le troisième vient d'être refait, ou son bail se termine plus tard. La plainte d'un locataire sur la température force la décision pour les deux autres. La Thermopompe 4-Zones DURASTAR Sirius Heat | 36 000 BTU - R410A permet de couvrir ces deux logements avec quatre têtes reliées à une seule unité extérieure, sans toucher aux installations du logement qui reste en place.

Ses cotes sont de 20,0 SEER2, 12,5 EER2 et 9,7 HSPF2. Le système est homologué ENERGY STAR avec la désignation climat froid sous l'ID ENERGY STAR 2410628, chauffe jusqu'à -30 °C et donne droit à une subvention LogisVert de 4 200 $.

Le R-410A, ce que cela implique pour ce châssis

Le R-410A circule dans tout le système, du châssis DRA4H36M1A jusqu'à chacune des quatre têtes. Sa manipulation relève de la licence en réfrigération, et la charge se fait au vide, après essai d'étanchéité. Dans un triplex où des lignes traversent déjà la façade, leur reprise dépend du diamètre, de l'état interne et de l'essai.

Deux mesures publiées telles quelles

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. Pour un triplex, nous retenons le point à -15 °C, avec un COP de 1,90 : c'est là que se joue la saison de chauffage. Ces valeurs proviennent du certificat AHRI 210568217, publié par le NEEP. Les 379 PCM, les 36 à 43 dB(A) et le boîtier de 22,44 x 22,44 x 10,24 po sont ceux de la tête de référence, pas des quatre têtes.

LogisVert, pour un immeuble à trois logements

Ce système figure sur la liste des thermopompes admissibles au programme LogisVert d'Hydro-Québec, avec 4 200 $ pour un propriétaire d'une habitation existante, selon la liste en vigueur à la date d'installation. Une aide bonifiée s'applique à certains immeubles à logements multiples, ce qui vise un triplex. La page subvention thermopompes efficaces d'Hydro-Québec en résume les conditions.

Deux-Montagnes : la mise en route, une fois les deux logements raccordés

Quatre têtes réparties sur deux logements

Les 36 000 BTU/h forment une réserve commune aux quatre zones : deux têtes dans un logement et deux dans l'autre ne se partagent pas la capacité à parts égales, elles la prennent quand elles en ont besoin. Un locataire qui coupe sa zone ne prive pas les trois autres. Chaque tête a sa propre paire de lignes, donc quatre parcours sur la façade arrière. Les ensembles publiés comprennent DRAM18F1A, DRAC12F1A, DRAS12F1B et DRAD09F1A.

Ce qui se règle au moment de la mise en route

Une fois les quatre paires de lignes tirées et le circuit éprouvé, chaque zone est démarrée seule pour vérifier sa modulation, son écoulement de condensat et la réponse de sa télécommande. C'est aussi le moment de ce qui s'explique aux occupants :

  • Un délai de trois minutes au redémarrage protège le compresseur
  • La vapeur blanche vue dehors correspond à un dégivrage
  • Une zone coupée par un locataire n'agit pas sur les trois autres

L'unité extérieure, à 62 dB(A) pour un boîtier de 37,48 x 16,34 x 52,48 po, se pose au-dessus de la ligne de neige, à l'écart des fenêtres de chambre du logement non converti.

Le circuit de 60 A et le compteur du propriétaire

La fiche demande 220 V, un MCA de 40 A et un disjoncteur de 60 A sur un circuit dédié. Dans un triplex, la question n'est pas que le calibre : une seule unité extérieure sert deux logements, donc un seul compteur porte la charge, et ce choix se fait par écrit avant la commande. Nous annonçons toute mise à niveau avant la signature, et la pose reste apparente, avec recouvrement de finition.

AirGreen, quand un locataire a signalé le problème

Entreprise familiale depuis plus de quinze ans, nous intervenons à Montréal, Laval, Longueuil, sur la Rive-Nord et sur la Rive-Sud, avec les licences RBQ en ventilation, en réfrigération et en électricité. La soumission est remise par écrit. Les filtres des quatre têtes se rincent aux deux semaines et l'entretien CVAC annuel couvre serpentins, condensat et raccords ; notre service de nettoyage s'en occupe.

Planifiez votre estimation gratuite pour la Thermopompe 4-Zones DURASTAR Sirius Heat | 36 000 BTU - R410A. Nous établissons quel compteur porte le circuit de 60 A, répartissons les quatre têtes entre les deux logements et démarrons chaque zone séparément.

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

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 4 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.
