Senville LETO 9,000 BTU 115V (SENL-09CD-16)

4.0

1 sourceall derived$699.99as of Oct 16

The Senville LETO SENL-09CD-16 is a 9,000 BTU ductless mini-split heat pump that runs on a 115V circuit. In a video review after about three weeks of use in his kitchen, Fix It Scotty called it very quiet, inside and out, and economical, and said it would be a win overall if it lasts. The catch is installation: he describes it as a job for a fairly advanced DIYer, because the line set has to be cut, re-flared and vacuumed down with a pump before the refrigerant is released.

Strengths

— Very quiet indoors, and Fix It Scotty says the outdoor unit is about as quiet, without the usual compressor grind
— Economical: Fix It Scotty cites a $699 retail price for the unit and put his total at under $800, as he already owned the tools
— Runs on a 115V, 15-amp dedicated circuit in the 9,000 BTU size, per Fix It Scotty

Watch-outs

— Installation needs a fairly advanced DIYer: Fix It Scotty had to trim and re-flare the line set, then vacuum it down with a pump and check for leaks with a gauge set before releasing refrigerant
— A dedicated circuit and outdoor disconnect are needed; Fix It Scotty suggests an electrician if you are not comfortable working in your panel
— Line set cover and outdoor wall bracket are not included; Fix It Scotty bought both separately

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.

Senville LETO 9,000 BTU 115V (SENL-09CD-16)

Like the Della Optima Series 12,000 BTU 115V, the LETO runs on a 115V circuit, but it is a smaller 9,000 BTU unit, and its listing rates the heat pump to 5F against the LG Artcool Deluxe KNSAL's full heating capacity at -13F. Unlike the Della, which Wired had professionally installed, the LETO's hands-on source installed it himself, line set vacuum included.
