The DIRECT AIR space at AirGreenSold and installed by AirGreen
Heat Xtreme Pro R-410A: at least 100% of its rated capacity, certified at −15 °C.
It comes in 5 sizes, from 6,000 to 24,000 BTU/h. The Direct Air brochure states operation down to −35 °C; the figures published by ENERGY STAR and NEEP stop at −15 °C. At that temperature, every size delivers at least its rated capacity.

Every size, point by point.
Identity, heating at the three test temperatures, seasonal efficiency, installation and LogisVert amount. “Not published”: Direct Air does not give the figure.

What people ask us, and what the sources say.
What is the DIRM-12HXPRO28-1Z?
It is the outdoor unit of the 12,000 BTU/h Heat Xtreme Pro R-410A. Paired with the DIRM-12HP-WM wall head, it forms AHRI system 207743725: 12,000 BTU/h certified at −15 °C (COP 1.80), SEER2 25.5, LogisVert $1,200 on the October 14, 2026 list.
Does the Heat Xtreme Pro really work at −35 °C?
The Direct Air brochure (July 2022) gives a heating range of −35 to 30 °C. The figures published by NEEP and ENERGY STAR for this R-410A version stop at −15 °C. Between −15 and −35 °C the unit is designed to run, but no capacity figure is published.
R-410A or R-454B: which one?
The R-454B adds a point listed at −30 °C and a refrigerant with a GWP of 470 (versus 2,088). The R-410A has a published warranty (10 years compressor, 5 years parts and labour) and a slightly higher SEER2 at every size. At −15 °C both deliver at least 96% of their rated capacity. The size-by-size comparison is above.
What is the Heat Xtreme Pro R-410A warranty?
According to the July 2022 Direct Air brochure: residential, 10 years on the compressor, 5 years on parts and 5 years on labour; commercial, 5 years on the compressor and 1 year on parts. Direct Air offers an online registration form, with no published deadline.
Is Wi-Fi included?
The brochure lists Wi-Fi as an option. If you want it, we list it on the quote.
Do the 6,000 and 9,000 BTU/h sizes qualify for LogisVert?
No: LogisVert requires a rated cooling capacity of at least 12,000 BTU/h. For the Heat Xtreme Pro R-410A, the amounts on the October 14, 2026 list range from $1,200 (12,000) to $2,544 (24,000).
