How Many Heads Can You Put on a Mini Split?

A ductless mini split system includes an outdoor compressor as well as indoor air-handling units, which are technically referred to as heads. The placement of these heads, as well as their number, can vary depending on the home or commercial building.

How many heads can go on a mini split? That all depends on the size and style of the residential and commercial properties.

Where to Put Mini Split Heads – The Factors That Play a Role

Now that you know how many heads can go on a mini split unit, the question becomes how many does your home or commercial building need? Here are the factors that you must consider as you make up your mind.

  • Your region: If you’re in a cooler region throughout the country, then you’ll be more interested in heating than cooling. In a hotter region, it’s the opposite. Should you be in the more temperate band, then you won’t be overly reliant on heating or air conditioning. Thus, you might be able to use fewer heads for your mini split than someone in the above two regions.
  • Your square footage: The greater the square footage that’s required for heating and cooling, the greater the number of heads. For a smaller home or commercial building, you’d naturally reduce the number of indoor air-handling units since you don’t have as much space to heat or cool.
  • Your home/building’s insulation: Is your home or building already well-insulated? Insulation can hold in heat. This doesn’t solely benefit you in the winter, but insulation can keep your home temperate in the summertime as well. As a result, you won’t need as many heads as a home or building with less insulation or none at all.
  • Sun exposure: How many windows does your home or commercial building have? How much sun exposure does the building receive on an average day? These factors can make your home hotter even if you don’t necessarily live in a warm region. Thus, we’d recommend more mini split heads in most instances.
  • Weatherproofing: Does your home or commercial building have drafty windows or doors or is everything airtight? If it’s the latter, then the temperature you choose is where your home or building will stay, give or take. The less airtight your building, the easier it is for outdoor drafts to enter. Increase the number of heads.
  • Occupants: People give off heat just by living and breathing. To combat the increase in humidity, it’s a good idea to have more heads. Thus, a commercial building used as a workplace would need more mini split heads than an average home. A six-family home would want more indoor air-handling units than a four-family home.
  • Lighting: The type of illumination in your commercial building or home also impacts how comfortable the building feels. If you use primarily LEDs, these lights give off less heat than other types of light. An extra mini split head or two can combat the heat generated by fluorescent and incandescent bulbs.
