What is a Ductless Heating System?

A ductless mini-split is a type of heating and cooling system that does not require any ductwork. It contains two main parts: an indoor and outdoor compressor unit. The indoor part has a conduit that connects to refrigerant and power lines, while the outdoor unit has a pump that brings in or pushes out heat. 

Ductless heating systems are very flexible to install. They are only limited by the length of the cables to connect to the outdoor compressor, meaning this type of HVAC system can be installed practically anywhere in your home.

Where to Install a Ductless System

Homes with the following qualities are excellent candidates for a ductless system:

  • Homes without air ducts
  • Newly constructed rooms
  • Guesthouse, shed, garage, etc
  • Rooms that are too cold even with the heater on 

Advantages of a Ductless Heating & Cooling System

Energy Efficiency

One of the biggest advantages of a ductless heating system is energy efficiency. Unlike central AC systems, ductless mini-splits can’t lose air through leaks in the ductwork.

This system also allows you to heat individual rooms instead of the whole house. For example, if you are an empty-nester or have rooms that are not commonly occupied, you can opt to install a ductless mini-split in the rooms you use the most. This way, you don’t waste energy heating up parts of your home that don’t need it. 


A ductless heating system offers extra comfort and flexibility. You can “zone” your home, which means you can accommodate everyone’s temperature needs at the same time. Instead of a central system where you set one temperature for the entire house, everyone can decide the amount of heating they would like in their room.

By only heating certain parts of your house, you are also saving money. Instead of turning off and on an entire central AC system, you just need to turn on whichever ductless mini-split you would like to use. It’s also much less noisy than a central system and does not take up as much space.

You can opt for a versatile ductless mini-split that does both heating and cooling. This can bring you comfort all year long, whether you want to cool off to warm up. 

Disadvantages of Ductless Heating

There are a few disadvantages to a ductless heating system that are important to consider when deciding if it’s time to install one in your home.

Upfront Cost

The most important disadvantage to consider is the upfront cost of a ductless system. The price you will pay depends on the number of mini-splits you would like to install. Based on this, the final cost can range anywhere from $1,800 to $8,000. 

While initially, a ductless system may be costly to install, it’s essential to consider the long-term benefits. If you can handle the upfront cost, it may be a worthwhile investment to save money on your electricity bills in the future. 

It can also cost a little more if you decide to get a ductless mini-split that does both heating and cooling. However, not every model offers this, so it’s another factor to consider. 


Lastly, the style of a ductless mini-split may not match your home’s aesthetic. Often these systems only come in white or beige and may not fit in with the rest of the room. 

Is a Ductless System Worth It?

Overall, a ductless heating system is well worth its cost. 

  • The amount a household can save by installing a ductless mini-split far outweighs the initial cost
  • Ductless systems offer extra comfort, versatility, and higher energy efficiency. 
  • Unlike a central system, a ductless mini-split won’t lose heat through your ductwork and will have no issue heating up on command.
