Our scoreSCORE5.1 / 10SCORE6.9 / 10
Our takeThe only 115V Uni-Fit that heats, with a 4,200 BTU resistance strip. Fine for taking the edge off a room; for real winter heat you'll need 230V or a heat pump.Our window heat pump pick for cooling plus spring and fall heat: CEER 14.5, Most Efficient, sold by Amazon. The heat pump shuts off below 41°F outside, so pair it with a space heater anywhere it freezes.

Watch out forFriedrich's manual says to replace the sleeve's old rear grille with the dual-intake grille in the kit; owners report installers skipping it and units failing soon after. The 230V UET10B33A and UET12B33A make 10,600 BTU of strip heat.Below 41°F outside the unit shuts off and shows LO (manual); owners who checked found no firmware that lowers it. Owners report rattles in the first days; adhesive foam at contact points helps if the cause is the window or bracket. A conventional box unit, not U-shaped; Midea's U models have no heat mode.
