04 · The cold
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
Standard
-25 °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.

07 · Good to know
What to know before choosing.
01
One unit, several room counts
The same outdoor unit is sold for 2 rooms and up, to its maximum. That is why one model shows up on several “rooms” pages.
02
The LogisVert amount of a multi-zone
The AHRI number and the amount belong to the outdoor unit, not to the number of heads. The “1st generation” listings have no AHRI number: amount on quote.
03
Standard R-454B: down to -25 °C
DURASTAR’s submittal for the DRA4U28M2A (V1.0_10.24) lists heating down to -25 °C, like the rest of the non-Sirius range. The Sirius Heat units go down to -30 °C.
04
Heads of your choice
Cassettes, consoles, ducted, floor-ceiling units: DURASTAR’s multi-zone listings show the heads that work with each outdoor unit. The mix is confirmed in the quote.

10 · Questions
What people ask us about these DURASTAR units.
How many rooms with a DURASTAR multi-zone?
Up to 6 on R-454B and 5 on R-410A, depending on the outdoor unit. Each card in the selector shows the model’s maximum.
Does every room need a wall unit?
No. The heads can be wall, cassette, console or ducted units; the exact combination is confirmed in the quote.
Why does the same model appear several times?
An outdoor unit accepts a range of room counts. We list it for each count it accepts, with the same AHRI number and the same LogisVert amount.
One multi-zone or several wall units?
A multi-zone keeps one unit outside for several rooms. Several wall units mean one outdoor unit per room. We compare both with you, with each option’s AHRI number.
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.
