What Is a Ductless Mini-Split?

Ductless mini-splits are an incredibly simple, flexible, and reliable way to heat or cool your home. Unlike a conventional air conditioning system, mini-splits do not require ductwork to distribute temperature-controlled air throughout your home. Instead, a single unit is installed in every room or area that you are looking to cool or heat. These systems are extremely energy-efficient because they allow you to have total control over which areas in your home are being heated or cooled. That means that you don’t have to heat or cool your entire home at once (like with a conventional HVAC system) when you are only using one room. 

Ductless mini-splits are often installed in:

  • Bedrooms 
  • Garages 
  • Enclosed patios 
  • Finished basements 
  • Sheds 
  • Living rooms 
  • Finished attics 
  • Guest rooms
  • New additions
  • Master bedrooms 

They are referred to as “mini-splits” for two reasons: 1) because these units are much smaller than traditional HVAC units and 2) because each system is split into two units (an inside unit and an outside unit). 

What Size Mini-Split Do I Need?

Wondering what size mini-split you need to install? It all depends on the size of the space you are trying to heat or cool. 

Below is a basic breakdown of the different mini-split sizes based on the size of the room/area you are installing them in:

  • 150-250 square feet (space size): Mini-split with a capacity of 6,000 BTUs per hour
  • 250-300 square feet (space size): Mini-split with a capacity of 7,000 BTUs per hour 
  • 300-350 square feet (space size): Mini-split with a capacity of 8,000 BTUs per hour    
  • 350-400 square feet (space size): Mini-split with a capacity of 9,000 BTUs per hour 
  • 400-450 square feet (space size): Mini-split with a capacity of 10,000 BTUs per hour
  • 450-550 square feet (space size): Mini-split with a capacity of 12,000 BTUs per hour

How Does a Ductless Mini-Split Work?

Ductless mini-splits use electricity to heat or cool a home. The exterior unit draws in outside air through a vent and then transfers the air to the inside unit through a small tube. The inside unit then heats or cools the air and delivers it to the inside space.
