In short

The Durastar Standard R454B 18 000 multi-zone heat pump heats and cools 2 rooms with a single outdoor unit. ENERGY STAR cold-climate certified, it delivers 16,000 BTU/h at −8 °C, heats down to −25 °C and qualifies for a $1,920 LogisVert grant. Installed by AirGreen in Montréal, Laval, Longueuil, the North Shore and the South Shore.

DRA3U18M2A

Outdoor unit

One compressor for the whole house. It supplies up to 3 heads and modulates from 5,700 to 16,000 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.

16,000 BTU/h÷ 1,000 ×$120=$1,920

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 215359230). 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.

La suite du sous-sol et la pièce vitrée de l'étage ne demandent jamais la même chose

Dans Villeray, une maison dont le sous-sol est aménagé en suite louée à l'année vit sur deux régimes. En bas, un locataire à demeure et une température constante. En haut, une pièce vitrée ajoutée du côté cour, impossible à tempérer, brûlante dès que le soleil tourne. La Thermopompe 2-Zones DURASTAR Standard | 18 000 BTU - R454B place une tête à chaque étage, avec une commande indépendante pour chacun.

Les capacités certifiées de ce format au R-454B

  • 23,0 SEER2, 12,5 EER2 et 10,0 HSPF2
  • À -8 °C : 16 000 BTU/h, COP de 2,38
  • À -15 °C : 13 500 BTU/h, COP de 2,2
  • À -25 °C : 7 000 BTU/h, COP de 1,29

Le COP de 2,2 à -15 °C est le chiffre qui pèse quand une suite est louée : le locataire chauffe sans que la facture du propriétaire suive la courbe du thermomètre. La désignation climat froid accompagne ces valeurs, avec un chauffage annoncé jusqu'à -30 °C. Ces chiffres sont ceux du certificat AHRI 215359230, tels que publiés par le NEEP, et l'appareil est homologué ENERGY STAR.

Une capacité par étage, pas une moyenne pour la maison

Un sous-sol enterré sur trois côtés demande peu et surtout de la constance ; une pièce vitrée orientée à l'ouest demande beaucoup, mais quatre heures par jour. Les répartir sur deux zones évite de surdimensionner l'ensemble pour satisfaire la pièce la plus exigeante. L'appareil de référence de la fiche descend à 24 dB(A) pour 418 PCM, ce qui compte dans une chambre de sous-sol ; chaque tête retenue a ses propres cotes.

Une aide de 1 920 $ pour ce système

Le programme LogisVert d'Hydro-Québec verse 1 920 $ sous l'ID ENERGY STAR 3621125, pour un propriétaire d'une habitation existante et selon la liste en vigueur à la date d'installation ; une aide bonifiée vise certains immeubles à logements multiples. La page de la subvention thermopompes efficaces d'Hydro-Québec détaille les conditions, et nous préparons les pièces du dossier.

L'ordre des interventions quand un locataire habite le sous-sol

Avant : le choix des deux têtes et l'avis au locataire

Le DRA3U18M2A est catalogué jusqu'à 3 zones et en dessert 2 ici. Les deux appareils intérieurs se choisissent dans la liste de compatibilité, des cassettes DRAC18F2A aux consoles DRAS12F2A, selon la hauteur libre du sous-sol et le dégagement de la pièce vitrée. Elles puisent dans la même capacité de compresseur, qui ne s'additionne pas d'une tête à l'autre. L'accès au logement loué se convient par écrit avant la date, avec la plage horaire.

Pendant : le condenseur, puis les deux montées de lignes

Le condenseur mesure 31,69 x 12,99 x 21,81 pouces et produit 55 dB(A). Il se pose côté cour, au-dessus de la ligne de neige, sur base au sol ou sur support ancré dans la structure, à distance des fenêtres de chambre, y compris de celles du voisin mitoyen. Deux paires de lignes partent ensuite vers le sous-sol et vers l'étage, entièrement apparentes, sans travaux à l'intérieur des murs.

Après : le circuit de 15 A et la mise en service

L'alimentation en 220 V demande un MCA de 15 A et un disjoncteur de 15 A sur un circuit dédié, une exigence modeste qui simplifie le raccordement dans une maison de quartier ancien. Couper la zone du haut n'arrête pas celle du bas : la mise en service se fait zone par zone, en présence de chaque occupant.

  • Le dégivrage produit de la vapeur au condenseur, surtout par temps doux et humide.
  • Un délai de trois minutes au redémarrage protège le compresseur.
  • Le sifflement bref du réfrigérant suit chaque changement de zone.

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 en saison et l'entretien CVAC annuel couvre serpentins, condensat et raccords électriques.

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: 16,000 BTU/h at −8 °C, 13,500 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?

$1,920 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 3621125. It also meets the ENERGY STAR Most Efficient criteria, according to the ENERGY STAR database.

Down to what temperature does it heat?

Down to −25 °C.

Is it noisy?

Indoors, the reference head goes down to 24 dB(A). Outdoors, 55 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.
