Seven sizes, from 6,000 to 33,000 BTU/h, all ENERGY STAR cold-climate certified, three of which no other Senville wall series offers: 6,000, 15,000 and 33,000. NEEP publishes a point at −30 °C for six of them; the 15,000 stops at −25 °C. The 33,000 earns $3,840 of indicative LogisVert, the highest amount among our Senville wall units.

This page answersFor anyone who wants a Senville wall unit that still heats in the middle of January: which AURA size for which room, what each one certifiably delivers at −8.3, −15 and −30 °C, and the three sizes only the AURA comes in.
Seven rungs, from 6,000 to 33,000 BTU/h: find yours
In deep cold, heat is what counts, not the cooling label. Each rung gives, for one size, the certified heat at −15 °C and at the coldest published point, the LogisVert amount, the line-set sizes and the maximum length set by the manual. At the visit we assess the room, then pick the rung.

At −8.3 °C as at −15 °C, NEEP publishes the same rated capacities for these three AURA units: 12,000 then 11,500 BTU/h. What separates them lies elsewhere: cooling, seasonal efficiency, the coldest point and LogisVert.

20,700BTU/h at −30 °C, AURA 33,000maximum capacity reported to NEEP, COP 1.40
It is the most heat published at −30 °C among the Senville wall units we sell: 1.7 times the next one (11,900 BTU/h). At the other end of the ladder, the AURA 6,000 keeps 3,200 BTU/h at that temperature.
Montreal drops below −30 °C on average 0.27 days a year (1981–2010 normals): this point shows the unit still runs in that cold, at reduced capacity.
The 15,000 is the exception in the series: its coldest published point on NEEP is −25 °C (7,800 BTU/h maximum, COP 1.41), and its senville.ca page also says −25 °C, while Senville files the AURA under its “Arctic Series (Up to -30°C)”. We show −25 °C for this size.

Senville pairs the wall AURA with its WRD-RMTIQ wired controller and states that its mini splits do not work with regular household thermostats. The Alexa USB kit is in the box; the Senville app needs a Wi-Fi kit sold separately.
On its AURA pages, Senville includes a 16 ft (4.9 m) installation kit at no charge, with 25 or 50 ft as options; for the LETO, a kit comes only when selected. On site, the real length follows the route between the two units.

Questions
What Senville publishes about the AURA, answered with the figures
Can I install the AURA myself?
No. Senville answers it on the AURA 12,000 page: “Professional installation is required for refrigerant handling, system commissioning”. See the warranty terms
Question published by Senville: “Can I install the system myself?”, FAQ of the SENA-12HF page on senville.ca, read October 14, 2026.
What is the warranty on the AURA?
10 years on the compressor and 5 years on parts, per Senville’s help centre and product pages. The French page of the AURA 18,000 is headed “Garantie de 10 ans”: that is the compressor; parts stay at 5 years. See the warranty terms
Question published by Senville: “What is the warranty on Senville products?”, help centre, modified October 8, 2026; SENA-18HF page on fr.senville.ca, October 14, 2026.
How often should I clean the AURA’s filter?
Every two weeks, per the AURA owner’s manual: “Make sure to clean the filter every two weeks.” Senville’s help centre, written for the whole range, says every 30 to 60 days, with a professional inspection once a year. For the AURA we follow the manual, which is stricter.
Question published by Senville: “How Often Should I Service My Mini Split?”, help centre, read October 14, 2026; owner’s manual CS019UI-EP(R454B), May 16, 2024, p. 16.
The room is far from the outside wall: how long can the line set be?
The AURA is pre-charged for 7.5 m (25 ft) of line set, with a 3 m minimum. Beyond 7.5 m, the installation manual calls for added R-454B: 0.16 oz per foot (15 g/m) on a 1/4 in liquid line, 0.32 oz per foot (30 g/m) on a 3/8 in line. Maximum length runs from 25 m (82 ft) for the 6,000 to 12,000 up to 50 m (164 ft) for the 24,000 and 33,000; for the 15,000, the dedicated 15,000/33,000 manual Senville links could not be read (not published here).
