You do not need a ductless unit in every room of your home. However, a single wall-mounted ductless unit can only cool one room or unobstructed zone (with good airflow). Thus, most Edmonton homeowners opt to install a wall-mounted mini split AC unit in each main living space they want to keep cool.
Keep in mind that one outdoor ductless condenser unit can support multiple (up to four) indoor units. Thus, one outdoor unit and four indoor units would cool four rooms.

Our professional HVAC technicians will help you decide how many indoor units you need, where to install them, and what size and model of mini split AC will work best for your Edmonton home.
