Our takeNearly the Universal 2-ton's cold-weather heat (21,600 Btu/h at 5°F) with a warranty that allows owner installs on MRCOOL's Quick Connect line set. The air handler is 21 in wide.For a big open zone in a cold climate with a contractor doing the install: 24,200 BTU/h at 5°F. Its high minimum output rules out single rooms.

Watch out forInstall type 'quick-connect' assumes MRCOOL's optional No-Vac line set; the system also ships for flare or braze connections with a vacuum. Some Amazon listings carry older CENTRAL-xx-HP-230A00 model codes; match the 230B00-O suffix. The install manual still calls for a licensed installer and licensed field piping; the warranty is what exempts a Quick Connect install.Senville's 24k page shows a ceiling-cassette spec table, so these figures come from NEEP only. The Amazon 24k listing (SENA/24HF) doesn't state refrigerant; confirm the model before you pay. Senville sells the Aura on Amazon itself, and SENA-12HF-16 is the kit number Senville's own site lists for the current R-454B Aura; a few listing fields (a 25.5 efficiency figure, a 2-year parts warranty) still show older numbers, so go by Senville's spec sheet. Current R-454B wall pairings are SENA-xxHF-OG + SENA-xxHF-IGG; older R-410A pairings end /OQ + /IQ. Senville's site lists higher HSPF2 and 47°F heat than the AHRI figures on NEEP; we use the certified numbers. Senville's FAQ says no to owner installs, and the warranty requires a licensed HVAC contractor.
