Senville 36000 BTU Ductless Mini Split System & Heat Pump | SENL/36CD brings Senville ductless climate control to retrofits and additions: inverter-compressor outdoor unit paired with wall-mount, ceiling cassette, or concealed-duct indoor. Inverter compression keeps the outdoor unit modulating rather than cycling, which translates to lower noise, lower utility bills, and longer compressor life than older single-stage alternatives. Across a multi-zone install, individual indoor units handle their own thermostat and setpoint, the family room comfortable at one temperature, the home office at another, all driven by the same outdoor condenser. The ductless format opens climate control to spaces where central HVAC ductwork isn't viable, finished basements, attic conversions, garage workshops, and additions over unconditioned crawlspaces. Once installed by HVAC trade, the indoor unit absorbs the room's climate management with whisper-grade blower noise and inverter-compressor efficiency, the kind of system that runs without announcing itself. The ductless format opens climate control to spaces where central HVAC ductwork isn't viable, finished basements, attic conversions, garage workshops, additions over unconditioned crawlspaces. Heat-pump operation delivers both heating and cooling from the same outdoor unit, with inverter compression maintaining efficiency across the temperature swing.
