DURASTAR Sirius Heat R-410A central systems: 2 units, heats down to -30 °C
A home with ducts: a heat pump outside and an indoor air handler that pushes the air through the ducts. Sirius Heat is DURASTAR’s deep-cold family: it heats down to -30 °C and keeps 100% of its rated heating capacity down to -18 °C, per the manufacturer. The R-410A version, still allowed in Canada for a residential heat pump.

Heat at -8 °C and -15 °C: values from each product listing; when the listing has an AHRI number, they are the ENERGY STAR (or NEEP) figures for that number. Cold limit: operating range published by DURASTAR for the family. “Standard” is our name for DURASTAR’s non-Sirius range.

How much heat is left when it gets cold, listing by listing.
Dark bar: heat at -8 °C. Light bar: at -15 °C. On the right, the limit DURASTAR publishes for each family.
The cold limit, by family
“Down to”: heating operating range from DURASTAR’s spec sheets (Sirius Heat: -22 °F / -30 °C; non-Sirius: -13 °F / -25 °C; 115 V: -4 °F / -20 °C). Sirius Heat keeps 100% of its rated heating capacity down to 0 °F (-18 °C). DURASTAR publishes no minimum for Advanced and Core.
Why the light bar is sometimes longer: in ENERGY STAR’s listing, the -8 °C (17 °F) figure is the capacity at the certification test point, while the -15 °C (5 °F) figure is the maximum capacity. Both come from the same AHRI number.

6 facts about these DURASTAR units and how they work. Flip the cards.
What to know before choosing.
“Electric furnace”: the indoor unit
On our site, each central system also exists under the name “electric furnace”: it is the indoor air handler (blower) of the same system, same series and same size.
Same outdoor unit, other air handler
The “variable speed”, “front return” and “mini-split” listings pair an outdoor unit already listed with another indoor unit. Each combination has its own AHRI number, so its own certified heat and its own amount.
Central mini-split: DRA1H or DRA1U with a DRAM air handler
The Sirius Heat and Standard R-410A central systems in our catalogue are central mini-splits: a mini-split outdoor unit (DRA1H or DRA1U) paired with a DRAM indoor air handler, per the listings.

Hydro-Québec pays $120 per 1,000 BTU/h of heat at -8 °C for an ENERGY STAR cold-climate heat pump, $50 for a standard ENERGY STAR one, if the outdoor unit is at least 12,000 BTU/h.
Amounts come from each product listing, by AHRI number, from Hydro-Québec’s LogisVert tool. Only Hydro-Québec confirms the aid granted.

Who makes DURASTAR?

We look at your home, choose the family and the size, check the LogisVert amount of the exact AHRI number, and hand you a clear quote.
Hydro-Québec does no phone or door-to-door solicitation for LogisVert. An unrequested call “on behalf of Hydro-Québec” is probably a scam.
