2 sourcesall derived

The Quilt is a ductless mini-split heat pump with a slim wall-mounted indoor head, outdoor units that serve two or three zones, and dial and smartphone controls, sold and installed only through certified contractors. Wirecutter's overnight test in the Catskills found it kept a room comfortable at single-digit outdoor temperatures and stayed near 50 dB at full fan speed, and it judged the design and controls a clear improvement on typical mini-splits. Gary Cruz, reviewing five heads in his own home after three months, praised the design, app and support but called the roughly $6,500-per-room price steep. It suits homeowners without ductwork who want an installed, good-looking system and can pay a premium; DIY installers and buyers outside Quilt's contractor network should look elsewhere.

Strengths
  • — Kept Wirecutter's test room warm with outdoor temperatures in the single digits °F
  • — Barely reached 50 dB at top fan speed in Wirecutter's noise test
  • — Slim indoor head with a front cover that can be painted or wallpapered to match a room
Watch-outs
  • — About $6,500 per room installed, steep next to DIY systems such as MrCool
  • — Only available through a limited network of certified contractors
  • — Depends on Wi-Fi; the only offline control was a fixed-temperature power switch

How they stack up

LG Artcool Deluxe KNSAL

The LG Artcool Deluxe KNSAL keeps full heating capacity down to -13°F, where the Senville LETO's entry rates heating down to 5°F. Its 12,000 BTU of cooling equals the Della Optima Series 12,000 BTU 115V and is above the Senville's 9,000 BTU. It lists 13,000 BTU of heating against 12,400 BTU for the Della, and it needs 208/230V where the Della and the Senville run on 115V.

Quilt Ductless Heat Pump (Quilt Mini-Split System)

Unlike the Senville LETO 9,000 BTU 115V and the Della Optima Series 12,000 BTU 115V, which are sold as single units, the Quilt is only sold through Quilt's certified contractors with installation in the quote. Like the LG Artcool Deluxe KNSAL, it is a premium heating and cooling system, but its indoor heads are designed to be painted or stained to match the room.
