Heating capacity, heating power, supply voltage, plug, cooling power, cooling current, refrigerant and warranty are from Sylvane's published specifications for this exact configuration, checked Oct 18, 2026.
Power while cooling: From the maximum cooling draw its retailer lists for this exact model. An hour's cost is at that draw and the US average electricity price of 18.44¢/kWh (U.S. Energy Information Administration, Electric Power Monthly Table 5.6.A (residential average, May 2026)). The compressor cycles once the room is cool, so most hours cost less.
Hourly heating cost: At the rated heating output and the US average electricity price of 18.44¢/kWh (U.S. Energy Information Administration, Electric Power Monthly Table 5.6.A (residential average, May 2026)). A thermostat cycles the heat, so most hours cost less. A heat pump's output and advantage shrink as it gets colder outside, and one with an electric back-up heater draws far more while that runs.
Will it fit your wall sleeve?
We could not confirm which sleeve sizes it fits from its maker's own documents, so check the installation manual against the inside width and height of your sleeve before you buy.

What to watch
- At 58 dB(A) it is louder than 20 of the 24 other through-the-wall units we list that publish a noise figure.
Installation & the rules that apply
This is a through-the-wall air conditioner. It sits in a sleeve built into an exterior wall, so the window-unit mounting and bracket rules do not apply to it. Swapping it into an existing sleeve is a like-for-like replacement; cutting a new opening changes the building's exterior wall, which usually needs a building permit and, in a condo, co-op or historic building, approval first.
