    How Much Does a Split System Air Conditioner Installation Cost?

    A split system air conditioner can switch between heating and cooling. It can eliminate the need to have two separate systems, or it can act as a supplemental heat source. The cost of a ductless split system installation cost can range from $600 to $5,400 for larger systems.

    Factors Impacting the Cost

    Brand. The brand of the unit can have a significant impact on cost. When comparing brands, make sure that you are comparing groups of similar size and power. You also need to compare the features and amenities. Given two identical units, the brand can have a significant impact on cost. The more expensive one might not be the best choice. Be sure to check reviews and customer ratings to see how they stack up. A Daikin 7kw split system price might be much more than an unknown brand. 

    Size. The size of the unit has an impact on the split air conditioner price. A smaller, portable unit can cost about $500, while a larger system typically begins around $900

    Size of Home. Choosing the size and type of unit that you need will have a significant impact on the split air conditioner installation cost. For a small apartment or studio, a portable unit might be all that you need. However, for a larger home, you might need a zone system. In general, you will need about 10W for every 100 square metres of space. 

    Different Technology Options. You can choose from a range of units from smaller portable ones to a larger capacity wall unit. For larger systems, you might need to have modifications to your electrical system, which can add to the cost. Ducted systems are often installed when the home is built. If you want to add the system in an existing structure, a ductless split air conditioning system can be installed with much less disruption and expense. You do not have to retrofit it to the existing system as you would with a ducted system. 

    Ongoing Maintenance/Parts. Another thing that you need to consider in the split system cost of the unit is the cost of maintenance and replacement parts. This is where buying a lesser-known brand can cost you more in the long term because parts might not be as readily available. Ongoing costs can include items such as fixing leaks, refrigerant recharge, tune-up, circuit board replacement, air filter replacement, and resetting the thermostat. These items can cost anywhere from $50 to $1,600, depending on the problem. 

    Heat and Cooling Loss. One factor that you will need to consider is the height of your ceilings and the number of windows that you have. Both of these factors can result in heating and cooling loss. Windows account for about 40% of the home’s heat loss.

    Price Estimates for Different Types of Split System Air Conditioners

    The type of system can also have a significant impact on the price of the style. Let’s explore the costs of serval options. 

    Reverse cycle split system. A reverse cycle system is one that uses the same coolant. The cycle can be reversed so that the liquid is either heated or cooled, depending on the need. Smaller reverse cycle systems begin in the $600-$900 range. 

    Multi-head split system. A multi-head split system allows you to heat and cool two different areas at the same time. You can choose the proper temperature for different zones of your house. They are typically more expensive than reverse cycle split systems due to the technology involved. They are a larger system and multi-split air conditioner price can start around $2,400 and up. 

    Mitsubishi 2.5KW Reverse Cycle split system. $750

    Fujitsu 12,000 BTU mini-split. $1,900

    Daikin 9,000 BTU multi-split system. $850
