Ductless air conditioning systems have been on the market for quite a while now, but it hasn’t been until recently that they’ve seen use in homes. Their primary difference from central air conditioning systems is the fact that they don’t require labyrinths of ductwork to distribute conditioned air throughout your home.
What is a Ductless Air Conditioning System?
Ductless systems, also known as split- or multi-split systems, operate on the principle of zoning—each area of your home gets whatever cooling or heating you want it to get without affecting other areas. They are composed of two systems: the outdoor unit and the wall- or floor-mounted units inside. The indoor units are placed at various locations in the home for optimum cooling, and each can be adjusted individually. This gives them a variety of advantages over central air units, including those listed below.
One of the greatest benefits of a split system is the flexibility it offers. Since it doesn’t rely on ductwork, you can increase the temperature control in areas where you need more cooling and lower it for those that aren’t used as often. Thus, you’re no longer stuck with one temperature for the whole building.
For example, suppose you’re in your south-facing living room, and you need it a little cooler since the sun is shining in through the windows. However, your cold-sensitive son is in the other room. With a ductless system, you can turn the thermostat down to make the change without causing your son any discomfort. Once you leave the room, you have the luxury of turning the unit off while you’re gone.
In addition to their zoning abilities, these units can be used for both heating and cooling, making them a great year-round temperature control solution for your home.
Ductless units have been shown to be more efficient than other systems, including window-mounted units and central air conditioning systems. The smaller size and potential for focusing on specific areas in the home make this possible. Homeowners who replace their current HVAC systems with ductless systems can expect to save somewhere between 20% and 30% on their energy bills throughout the year.
The greater energy efficiency afforded by a ductless unit lowers your electricity usage, which in turn reduces your carbon footprint. In addition, split-ductless air conditioning systems use an eco-friendly refrigerant called R410A. This refrigerant has been shown to have the potential for absolutely no ozone depletion for the life of your unit.
Better Indoor Air Quality
An air conditioning system not only regulates temperatures, but it also improves air quality. It does this by filtering out allergens and other airborne pollutants and distributing clean air throughout the room. Ductless systems are no exception to this.
With a central cooling system, ducts tend to get filled with dust, debris, and various other airborne particles that aren’t good for your health. As they force air through these ducts, that debris gets distributed throughout your home. Even once you change the filters and clean the ducts out, there could still be some left behind.
Multi-split systems don’t have that problem. With multiple layers of filtering, they can greatly increase the air quality in your home.
Simpler to Install
The installation of an efficient central air conditioning system requires a thorough analysis of each room, including its size, the direction the windows are facing, its insulation levels, and its distance from the unit. These are then carefully factored into calculations that determine how much heat will seep in or out during the day, which are then used to determine the size of unit you need and how large the ducts should be. In short, it’s a lengthy, technical process.
Installation for a ductless air conditioning system is much simpler and much more forgiving. Since each unit in a multi-split system is targeted to a specific zone, you can control the temperature separately for each room. Thus, if one room seems to need more cool air during the summer, you can make the adjustments after installation rather than weathering the automatic blasts of air that come from a central AC system.
Also, since there are no ducts to install, you save a lot of time and hassle on installation. The process will be much faster with far less impact on your daily life (and much smaller holes in the walls).
Choosing the Right Unit
In summary, ductless air conditioners are more efficient, easier to install, and ultimately more convenient and eco-friendly than other systems. To get the full scale of benefits, however, it’s important to choose a unit that’s designed to surpass energy efficiency standards. In addition, the installation should be made by a trained professional from an authorized distributor.
