What’s Advantageous about Ductless Systems?
Ductless systems, on the other hand, offer a whole new range of advantages to homeowners that centralized air systems cannot match. A ductless mini–split is a heat pump that is installed on the wall or ceiling of the room it is going to serve. A separate unit is installed outside the house, then connected to the inside unit by power and refrigerant lines. Up to four inside units can be connected to a single outside unit.
No Ducts, No Duct Leaks
Let’s take a look at the benefits of this kind of system. For one, the ductless unit eschews all ductwork in favor of delivering cool air directly to the room it serves. By doing this, it bypasses one of the biggest flaws in duct systems: leaks. As much as 30% of a central system’s output on average is lost to leaks in the ductwork. This makes a ductless mini–split much more energy efficient than a central air system.
Multiple Units = Greater Control
By using multiple ductless mini–splits instead of a centralized system, you also garner the advantage of finer control. Each ductless unit is outfitted with its own thermostat, allowing each room to have a different set of parameters for maintaining a comfortable climate. No more wasting energy with a one–size–fits–all solution.
Cooling as well as Heating
Finally, each ductless mini–split can also act as a heating system. This is done by reversing the flow of refrigerant in the system, making a ductless mini–split an energy efficient heater as well as an air conditioner. This could save you hundreds of dollars that would otherwise be spent on a completely separate heater.
