A ductless mini-split is a heating and cooling system that doesn’t require installing ductwork. It’s great for homes built on slabs, condos, or other buildings with no ductwork.
How Does the Mini-Split System Work?
The mini-split system is an air conditioning unit that separates the indoor and outdoor components of a central air conditioning system. This allows for greater flexibility in how you use your home’s cooling capabilities.
The mini-split system uses a blower to pump cool air into your home through ducts installed during construction or renovation. The unit is connected to the indoor and outdoor units via pipes, which run through the walls of your house.
There are two types of mini-split systems: single duct and multi-duct systems. In single duct systems, only one pipe goes from the outside unit to the inside unit—and then splits off to deliver cooled air through multiple vents throughout your home.
Multi-duct systems have multiple pipes going from the outside unit to different rooms in your house—each pipe splitting off into smaller pipes that deliver cooled air where needed.
A ductless mini-split only has two main parts:
1. The Indoor Unit Hangs on the Wall
The indoor unit contains an air filter that cleans incoming air before going through a heat exchanger (also known as a condenser). This heat exchanger removes excess heat from the inside air and sends it back through vents in your home. Once cooled down by the heat exchanger, this air is ready for use.
2. The Outdoor Unit Sits Outside
The outdoor unit contains a compressor, which uses electricity to produce refrigerant gas. This gas flows through copper tubing to an indoor coil, which cools down and turns into liquid again. The refrigerant then travels to an expansion valve, where the compressor pressurizes it before returning to the outdoor unit.
Advantages of Ductless Mini-Split Systems
Ductless mini-split systems offer a lot of advantages over traditional ducted systems. First, they’re much more energy-efficient. They’re even more efficient than central air systems, so they’re becoming popular in the United States. They use up to 60% less electricity than a standard air conditioner or furnace, making them great for businesses and homeowners who want to save money on their electric bills.
Another benefit of ductless mini-split systems is that they are quiet compared to central air conditioners or furnaces. You can’t hear them running when they’re functioning properly—they sound like normal background noise if you walk by one while running.
Ductless capacity is the maximum volume of air that can be moved through a ductless system. It is measured in cubic feet per minute, or CFM.
Ductless systems deliver cooling and heating energy to individual rooms or zones. The ductless capacity can vary based on factors, including the size of the room. For example, a 10-foot by 12-foot room will have a lower ability than an identically sized room with two people sleeping in beds with thick mattresses and heavy blankets.
The ductless system uses a fan to circulate air throughout your home, which does not have to be installed near a window or wall opening. As long as an electrical outlet is nearby, you can install a ductless system almost anywhere in your home. If you have an especially large living room or master bedroom, you may need more than one system installed to meet your cooling and heating needs.
How Are Ductless Systems Installed?
Ductless systems are installed in various ways, depending on the type of system you have, who you hire to install it, and where the installation will take place in your home.
If you are installing a ductless mini-split system, it’s important to choose an installer who has experience with this type of system. You can find an installer specializing in installing ductless mini splits for help.
Once you’ve found an installer, they will install your ductless mini-split system by drilling into the exterior wall of your home or building, then running a refrigerant line from the outside unit into your home or building through that hole. They’ll then set up the indoor unit in your home or building and connect it to the line from outside.
This process will need to be repeated for every room that gets a ductless mini-split. Since these systems can only treat one room, most homes require several mini-splits or just add them to a bonus room to save money on adding ductwork.
