Heat Pump and Ductless Mini Split: What’s the Difference?


If you’ve looked into these two pieces of technology, you’ve probably asked the question that many people ask us—what’s the difference between a ductless AC and a heat pump? While they might be similar in a lot of ways, they do have some key differences that are important to take note of if you’re going to invest in one of the systems.

The truth of the matter is that there is no “better” system. Each one of these HVAC machines functions differently and are perfect for different homes. By understanding the differences between these systems, you’re more likely to find the right one and have it installed in your home to better your comfort.

We’ll tell you everything you need to know about what system is right for you!

Similar Outcome, Different Machines

Heat pumps and ductless mini splits have one common goal—provide temperature control in your home to the specifications set on your thermostat. While they might both technically achieve this goal, the method by which they get the cooled or heated air into your home is different depending on the system. Let’s take a look at the specifics.

Heat Pumps

While technically a ductless mini split would be considered a “heat pump,” not all heat pumps are the same. Heat pumps produce cooled or heated air by running refrigerant in a cycle between an evaporator coil and a condenser coil. By doing this, it moves heat from inside your home to the outside, or vice versa, depending on the mode you’ve set.

Heat pumps run similarly to an air conditioner, by using your air ducts to distribute air throughout your home. That means they can be a perfect solution for homeowners with ductwork in good condition, but that want a system to keep them comfortable all year round.

Ductless Mini Splits

A ductless mini split technically functions as a heat pump, using refrigerant in almost the exact same way except for one crucial difference. A ductless system doesn’t use air ducts, which heat pumps can use. That means the refrigerant lines run directly to up to 4 air handlers that can be placed anywhere in your home.

What does this mean for your home? Well, ductless mini splits can be customized to run at different temperatures for different areas of your home, which a normal heat pump can’t do. Also, these systems don’t rely on air ducts, which means your old or small house doesn’t need to have extensive air ductwork installation performed in order to keep it comfortable.

The Verdict

Luckily, both of these types of systems are highly efficient and work like a charm. Whether or not you choose the ductless system because your home doesn’t have any air ducts, or you choose a heat pump because it’s more affordable or works with your air duct system, you’re in good hands. Just as long as you make sure to have the system installed by certified professionals!
