What Is A Ductless Mini-Split System?

A ductless mini-split system is a compact unit that is designed to heat and cool only a small area of your home. The system requires no ductwork, so you don’t need to expand your current ducts. Mini-split systems rely on an outside unit combined with a small wall-mounted unit inside the space that you want to heat and cool. The only modification to your home that is needed for this type of unit is hole through the wall that is just large enough for a flexible tube that delivers air and power to the indoor unit. The tube is only a few inches in diameter.

Benefits Of A Ductless Mini-Split System

• Compact design
• More affordable than expanding current HVAC system
• Energy efficient design
• Can be used for zone control
• Flexible coverage, from 200 square feet to 1,200 square feet or more
• Excellent for older and smaller homes with no existing HVAC systems and ducts
• Can be installed in detached exterior buildings, such as garages and workshops

How Does A Ductless Mini-Split System Work?

A ductless mini-split system works on the same principles as larger HVAC systems. The exterior unit draws in air through one or two vents. Some units have vents on the side and back, so the unit may need to be installed a foot or two from the exterior wall of your home. The unit also has an air outlet vent on the front. Some models may need to be mounted on a platform to allow for proper airflow, protect the unit from the elements, and prevent sinking and shifting. The unit draws air in and delivers it to the interior of your home through a small, flexible tube. The interior unit heats and cools the air and delivers it into the space. Ductless mini-split systems are controlled by remote.

Centralized HVAC Vs. Ductless Mini-Split System

Most homeowners in South Jersey and southeastern Pennsylvania are familiar with traditional HVAC equipment designs. These units rely on interior and exterior units to operate, as well as a series of metal ducts that are installed in the walls and ceilings of a home. Temperatures are controlled through thermostats that are mounted on the walls and hard-wired into the electrical system. Ductless mini-splits are much more compact, yet they can deliver the same comfortable temperatures to areas of the home or the entire space in smaller homes.

When A Ductless Mini-Split System Is Ideal

There are many situations for which the experts at JAMCO Heating & Air Conditioning recommend ductless mini-split systems to homeowners in south Jersey and southeastern Pennsylvania, such as:

• Garages
• Additions to existing homes
• Remodeling projects
• Setting up individual heating and cooling zones
• Updates to detached exterior buildings, such as workshops

Using A Ductless Mini-Split System

A ductless mini-split system is easy to operate and maintain. You simply set the desired temperature on the remote, and the unit takes care of the rest. The simplistic design makes maintaining the units more straightforward compared to larger HVAC systems. You can check and replace filters on your own, and we can include the unit in your routine maintenance schedule for the whole-house HVAC equipment.

Energy Efficiency Of A Ductless Mini-Split System

Ductless mini-split systems are incredibly energy efficient. Because the units only operate for smaller spaces, utility costs are significantly lower compared to centralized units that have to push air through ducts. On average, a ductless mini-split system uses about 60% less energy to operate.
