Which heat pump for a bedroom?
Updated October 24, 2026

Good to know
- The smallest wall unit (9,000 BTU) is enough for most bedrooms.
- For two or three bedrooms, a multi-zone often costs less than several wall units.
- The 9,000 BTU wall unit is not eligible for rebates; a multi-zone may be, depending on your province.
- Place the unit above the door or facing the bed to spread air without blowing on the bed.
