Mitsubishi – Mr. Slim JX Series 115V Wall Mount Heat Pump | R-454B | Toronto & GTA Installation Included
The Mitsubishi Mr. Slim JX Series is the only wall mount heat pump in the Mr. Slim lineup that runs on a standard 115V household outlet — no dedicated 240V circuit, no electrical panel upgrade required in most installations. Using next-generation R-454B low-GWP refrigerant and an inverter-driven compressor, it delivers 20 SEER2 cooling efficiency and 10 HSPF2 heating efficiency, with heating operation down to -25°C (-14°F). Available in 9,000 and 12,000 BTU. Price includes standard professional installation and up to 20 ft of lineset.
Every other ductless heat pump — including the Mitsubishi GX and FX Series — requires a dedicated 208-230V circuit and often an electrical panel upgrade. The JX Series is different:
- ✓Plugs into a standard 15A (9K) or 20A (12K) household circuit
- ✓No panel upgrade required in most homes — saves $800–$2,500+ in electrical costs
- ✓Ideal for condos, apartments, older homes, garages, and additions where running a new 240V circuit is difficult or costly
- ✓Lower total project cost — same Mitsubishi quality and efficiency without the electrical overhead
Note: A dedicated 15A (9K) or 20A (12K) circuit at the outdoor unit location is still required. If no circuit is available nearby, electrical work is quoted separately. Contact Bison Air to confirm your electrical situation before purchase.
