Our takeThe heat-pump Duo: 12,000 BTU SACC through one hose-in-hose duct, with an inverter, for a room no window unit fits. Heat stops below 41°F, and humid-climate owners end up draining cooling condensate by hand.For a wide window, 27-39 in with a 16 in opening, and a room up to 550 sq ft: CEER 15 and in-home warranty service. It weighs 85 lb, so plan on two people for the install.

Watch out for1-year warranty; the owner pays diagnostics, removal, transport and reinstallation for service. A retailer labels the heat 'Electric Heat'; the manual says heat pump. Check for the H in the model number; the MAP14S1TBL looks the same and doesn't heat. When we checked, the listing had no featured offer and one third-party seller.LG's 1-year warranty applies only when bought from an LG authorized dealer; ask a third-party seller. LG lists the same 1,020 W / 9.1 A for this and the 8,500 BTU model; treat the electrical figure as unconfirmed.
