What’s the Difference between a Ductless Mini-Split and a Heat Pump?

Hey there, comfort seekers! When diving into the world of heating and cooling, things can get a tad confusing. Ever heard of a ductless mini-split and wondered how it stacks up against a heat pump? If so, you’re in the right place. Let’s unravel this mystery together!

1. What are they, anyway?

First off, it’s important to understand the basics:

  • Ductless Mini-Split: This system has two main parts – an outdoor compressor/condenser and an indoor air-handling unit. As the name suggests, it doesn’t require ducts to cool or heat your home. Cool, right?
  • Heat Pump: A bit of a Jack-of-all-trades, a heat pump can both heat and cool your home. It does this by moving heat from one place to another. Instead of generating heat like a traditional furnace, it transfers it. Clever!

2. Do They Need Ducts?

One of the biggest differences is in the name itself:

  • Ductless Mini-Split: No ducts here! Perfect for additions to homes, new constructions, or places where duct installation would be challenging.
  • Heat Pump: Typically, heat pumps do use a duct system to distribute warm or cool air throughout the house. However, some heat pumps can be ductless too. Mind blown, right?

3. Efficiency & Cost:

Both systems are energy-efficient, but how they save energy is a tad different:

  • Ductless Mini-Split: Without ducts, there’s less energy loss. These systems can be a cost-effective solution for parts of the home that need separate temperature control.
  • Heat Pump: These are efficient because they transfer heat instead of producing it. They can save you a lot in energy bills, especially if you live in milder climates.

4. Installation & Flexibility:

  • Ductless Mini-Split: Since you don’t need ducts, installation can be simpler and more flexible. You can place the indoor unit on a wall, ceiling, or even as a floor model. It’s like customizing your own comfort zone!
  • Heat Pump: The installation process can be a bit more involved if ductwork is needed. However, if you already have ducts, it’s a smooth sailing process.

5. When to Use Which?

  • Ductless Mini-Split: Ideal for homes without existing ducts, for room additions, or for areas where individual temperature control is desired.
  • Heat Pump: Great for homes with existing ductwork or for those who want an all-in-one heating and cooling solution.


Both ductless mini-splits and heat pumps are fantastic options, offering efficient heating and cooling solutions. The choice boils down to your home’s setup and your specific needs. Remember, when in doubt, reaching out to a Carrier factory authorized HVAC expert (like us!) is always a good idea. We’re here to keep you cool (or warm) and comfortable!
