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.

The cold limit, by family
Sirius Heat
-30 °C
“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.

“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.
02
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.

10 · Questions
What people ask us about these DURASTAR units.
What is a DURASTAR “electric furnace”?
The indoor air handler (blower) of a DURASTAR central system. Each listing matches a central system of the same series and size, with the same AHRI number.
How is it different from the Central page?
They are the same systems, presented by their indoor part. If you keep your current furnace, see the ADD-ON collection instead.
Can my current ducts be used?
We talk about it during the free estimate, with your home in front of us.
How much is an installed DURASTAR?
Every installation is different: the estimate is free and the price comes with the quote.
Who makes DURASTAR?
DURASTAR is the house brand of Ferguson, a large North American heating and cooling distributor; in Canada, Ferguson does business as Wolseley. The Advanced and Core central systems are warranted by Rheem Sales Company. DURASTAR does not publish who makes its mini-splits.
