Are you building a new home? Is your air-conditioning system not working as well as it should? Is your AC nearing the end of its expected life span? Whether buying a new unit or replacing an old unit, you’ll need to decide what type of system you want. Many people are starting to go with ductless AC systems, while others are sticking with traditional duct systems. Some misconceptions exist concerning the ductless units. Learn the facts so that you can make a well-informed decision when purchasing your next air-conditioning system in Duluth, GA.

What Is a Ductless Unit?

A ductless unit, sometimes called a ductless mini-split, passes coolant between a condenser located outside your home and an evaporator located inside the home. While a central AC system sends air through the evaporator into the ductwork, the ductless system uses a cable to transfer the air. The slim cable is located between the condenser and a box inside your home. A ductless system can support up to four indoor air handling units. Unlike the central AC system, ductless units don’t use thermostats. Instead, you adjust the temperature using controls on the panel of the box or using a remote control. Like a central unit, a ductless unit heats during cold weather. There are some misconceptions surrounding ductless AC units. Keep reading to learn the ones you should stop believing.

Misconception: They Only Work for New Homes

You may have heard that ductless units work only for new homes. However, a ductless AC unit can be installed in an old home with ductwork. Your technician will seal the ductwork to keep out dust and pests. A ductless system can be installed in a new addition you are building to your home. It eliminates the need to install more ductwork.

Misconception: They Affect Air Quality and Distribution

Some people think that ductless units negatively affect air quality. Actually, a ductless system can improve air quality. Each air handler has a filter, and it’s easy to clean the unit. Another common misconception is that ductless units don’t distribute the cool or hot air evenly. Ductless units shouldn’t be confused with window air conditioners or space heaters. A ductless unit cools and heats a much larger area.

Misconception: They Have a Short Lifespan

Some people believe ductless systems don’t last long. With regular air-conditioning service and maintenance, a ductless unit can last as long or longer than a central system. They can last up to 20 years.

Misconception: They’re Large and Noisy

Some people picture ductless units as large and bulky. Ductless units are smaller than HVAC systems. They can be placed on a wall or ceiling so that they don’t take up any floor space. People also assume ductless units are very noisy. Early ductless units, such as central units, were loud, but technology has changed that. You can easily hear conversations and your sleep won’t be disturbed by a ductless unit.


Ductless AC systems are great for single-family homes, apartments, condos, and home additions, such as a sunroom. You control the temperature by zones, so you can put an end to fighting among family members over the thermostat settings. Ductless units are energy-efficient; they reduce the amount of energy lost through ducts, and they require less energy to operate. They’re better on the environment because they use a refrigerant that doesn’t contribute to ozone depletion.
