Benefits and Considerations of Mini Split Systems

One of the main disadvantages of duct air conditioning systems is that a certain amount of energy is lost as air travels through the ducts. This can account for energy loss of up to 30%. Because mini split heat pumps and A/Cs don’t use ducts, they’re more Eco-friendly.

Mini splits are an ideal choice in applications where a small heating and cooling unit is needed. They’re also useful when zoning, or cooling certain areas or rooms independently, is required. Some outdoor mini split components can be connected to as many as four indoor units that operate with their own thermostats. This can be an economical solution for homes or buildings in which only a few areas are primarily used. When shopping for a mini split, you’ll see systems rated as single zone, dual zone, triple zone, quad zone or more. Ductless A/Cs also offer flexible mounting options, as their fan components can be wall mounted, ceiling mounted or drop ceiling mounted. They can also rest on the floor.

Another benefit of mini split systems is their ease of installation compared to traditional duct systems. In addition, because the connecting conduits come in a variety of lengths, an outdoor compressor can be located farther away from the indoor vents — sometimes up to 50 feet. This can be beneficial for buildings in which the compressor needs to be installed in an inconspicuous place or in a remote location for drainage purposes.

Like all technologies, mini splits do come with a few drawbacks. One is their cost. These units are often more expensive than window A/Cs or duct systems. However, if you factor in the additional cost of retrofitting your home with duct work for a central A/C, they can be a more economical alternative, depending on the type of installation. Mini split A/C units also take up floor, wall or ceiling space. They don’t provide a flush mount installation as many are accustomed to with central air units.
