This includes additional material costs but also accounts for the added labor required from your contractor. In general, you should budget an extra $700 to $2,300 for each additional indoor unit installed. This cost range includes labor as well as additional supplies, like refrigerant lines and an installation kit. Some larger rooms with high ceilings might need two units, so it’s possible to have two zones in a single room.Ī standard system with an outdoor unit and single indoor head costs between $2,000 and $8,800. If you want to cool multiple rooms throughout your home, you’ll need to install multiple heads in different rooms. Number of ZonesĪ basic mini-split system has two main components: an outdoor condensing unit and an indoor unit (or head). HVAC techs can make recommendations on not only the size of the unit, but also on the number of heads needed, the most reliable brands and SEER ratings (more on that below). Work with an HVAC contractor to determine the size you’ll need to properly cool (and maybe heat) your home. A 60,000 BTU unit, for example, ranges from $3,500 to $10,000 and could cool 2,500 square feet of space.Ĭalculating what sized unit you’ll need can be challenging, especially if you’re used to central air. Homeowners who only need to cool a small space within their house may be able to go with a 6,000 BTU system ( $450 to $1,600), but big homes relying entirely upon a mini-split would need something much larger. On average, a 12,000 BTU mini-split system costs $3,000 fully installed. This means you don’t necessarily need to think about the square footage of your entire house when making a selection. Remember, unlike central air, which cools your whole house evenly, a mini-split system cools strategically chosen zones throughout your home. The larger the space you need to cool, the larger the unit should be-and thus the higher the BTUs.Īn average home requires a 12,000 BTU system, which can cool around 500 square feet of space. We measure the size of a ductless AC system using British thermal units (BTUs). Mini-split installation costs have a wide range-and that’s thanks to a number of factors that can affect pricing, such as the size of the unit and how many rooms (or zones) you want to cool throughout your house.
