Goodman Series 19 wall heat pump: five sizes, from 12,000 to 36,000 BTU/h
The only series that goes past 24,000 BTU/h among the GOODMAN wall units AirGreen sells. From one size to the next, the SEER, the outdoor sound, the line length and the fuse change, and not always the way you would expect. The ladder below lines them up, size against size.

GOODMAN//At the rating point
Watts and amps, in cooling and in heating
What each size draws at the rating point. In cooling, the 36,000 draws 18.5 A against 4.5 A for the 12,000, more than four times as much (AirGreen calculation). The circuit itself is sized from the minimum circuit ampacity and maximum fuse in the 19 ladder.

Did you know//GOODMAN documents
Three Series 19 figures people read too fast
01
"19 SEER" is a ceiling, not an average
GOODMAN heads the Series 19 page "up to 19 SEER". Size by size, it publishes 19.0, 19.0, 17.0, 18.0 and 16.0: only the 12,000 and the 18,000 reach 19.
Source 1, p. 502
Three outdoor footprints for five sizes
The 12,000 and the 18,000 share an outdoor unit footprint, 31.5 × 13.1 × 21.8 in; so do the 30,000 and the 36,000, 37.25 × 16.14 × 31.9 in in the 06-21 revision. Only the 24,000 has its own, 33.3 × 14.3 × 27.7 in.
Source 1, p. 5; source 2, p. 503
EER drops from 11 to 8.5
In cooling, GOODMAN publishes an EER of 11, 11, 9.5, 10.5 and 8.5, from 12,000 to 36,000: the 36,000 uses the most power per BTU/h of cooling. The 03-21 brochure labels that line "COP"; the 06-21 revision calls it EER.

Questions//Series 19
Questions about Series 19
Which Series 19 size for my room?
GOODMAN prints no application area for Series 19; its 2018 French-language document gives one only for Series 15, 17 and 21. So the size is based on the room's heating needs: floor area, windows, insulation.
Down to what temperature does Series 19 heat?
GOODMAN publishes its heating from -15 to 30 °C outdoors for all five sizes, and publishes no cold-weather capacity. As with any wall heat pump, the heat delivered drops as it gets colder; the backup heat is chosen at the estimate.
Can a Series 19 head go on a multi-zone outdoor unit?
GOODMAN's documents do not provide for it: Series 19 only appears there as single zone. The multi-zone outdoor units of the same brochure, the MST…E21, refer to the Series 21 heads.
Can my existing refrigerant lines be reused?
That is checked on site. GOODMAN calls for 1/4 and 1/2 in lines on the 12,000 and the 18,000, and 3/8 and 5/8 in on the 24,000, the 30,000 and the 36,000. We also look at their condition and their length.
Why do the 30,000 and 36,000 carry the E17 code?
GOODMAN does not explain it. The 03-21 brochure prints them as MSH303E19 and MSH363E19, the 06-21 revision as MSH303E17 and MSH363E17. In the nomenclature of its 2018 French-language document, the two digits after the E stand for the nominal SEER; GOODMAN publishes a SEER of 18.0 for the 30,000 and 16.0 for the 36,000. AirGreen sells the E17 units.

Five sizes, one for your room
At the estimate, we measure the room, choose the wall for the head and the spot for the outdoor unit, then route the refrigerant lines between them. The size comes from the room's heating needs; the wall and the line route follow.
