Atlanta Heating and Air Conditioning Guide: How Ductless Mini Splits Work

Posted by David Roussel

Ductless mini split systems are not new, but they’ve only recently started to gain popularity in residential applications. Many people are interested in these systems because of the high level of efficiency that they can achieve. Higher efficiency means that they use less energy to run, which has the potential to save Atlanta homeowners money. Ductless mini splits are also very good in situations where there currently isn’t a duct system like in old homes that used baseboard heaters or in new additions to homes.

How Ductless Mini Split Systems Work

As their name implies, ductless systems don’t use ducts to distribute the air throughout the home. Most traditional, forced air systems heat or cool the air with a heat source or heat pump system, and then push it throughout the house via a system of ducts. With the ductless mini split system, each room or “zone” has its own wall-mounted unit that provides the air in that specific room. The wall units are connected to an outdoor condenser unit by several tubes and electrical wires. The tubes carry refrigerant which is the fluid that carries the heat either to or from the house.

Why Ductless Mini Split Systems Are So Efficient

One of the main reasons that ductless mini split heat pump systems are so efficient is that they don’t actually burn any combustible fuel to heat your home. Instead, during the heating mode, the main heat pump captures existing heat in the outdoor air and transfers it to the air inside your home. Only very little electricity is used in this process. Another way that ductless systems are more efficient is that they don’t lose any energy as the air travels through the air ducts. As air travels through the ductwork in a forced air system, it can lose air and waste energy. With a ductless system, you don’t have that kind of energy waste. Additionally, if you have leaking ducts you could be heating or cooling the outside air, which is also wasteful.

One of the other main benefits of the mini split system is that you don’t have to heat or cool your entire home. Each room has its own wall-mounted unit which allows you to cool or heat only the rooms that you’re using. This eliminates the waste of heating or cooling a room that you’re not using.
