Heat pumps can be up to three times more efficient than traditional heating systems. That’s because they don’t generate heat—they simply move it from one place to another.
This makes them one of the best choices for heating and cooling homes. If you’re looking for an energy-efficient way to stay comfortable all year, you might be considering a ducted mini-split heat pump or a ductless mini-split system.
Both offer great benefits, but they work differently. So, which one is right for you? Should you go with a system that uses ducts or one that doesn’t? In this guide, we’ll break everything down in simple terms.
Ducted Mini Split Heat Pumps
What Are They?
A ducted mini split heat pump is a system that uses ductwork to distribute heated or cooled air throughout your home.
The indoor unit is usually hidden in an attic, basement, or closet. It connects to air vents in each room, just like a traditional furnace or central AC system.
Pros Of A Ducted System
- ✅ Even heating and cooling – You get consistent temperatures throughout the house. No hot or cold spots.
- ✅ Better aesthetics – The indoor unit is hidden. No bulky wall-mounted units.
- ✅ Quieter operation – These systems tend to be very quiet, especially compared to window units or baseboard heaters.
Cons Of A Ducted System
- ❌ More expensive installation – If your home doesn’t have ductwork, adding it can be expensive and disruptive.
- ❌ Energy loss – Some energy is lost through the ducts, especially if they aren’t insulated properly.
- ❌ More maintenance – Ducts need to be cleaned and checked for leaks.
Ductless Mini Split Heat Pumps
What Are They?
A ductless mini-split heat pump doesn’t need ducts. Instead, it has one or more indoor air handlers mounted on walls or ceilings. These units connect to the outdoor unit with refrigerant lines.
Each indoor unit controls the temperature in a specific zone of your home.
Pros Of A Ductless System
- ✅ No ductwork needed – Great for homes without existing ducts. No major renovations are required.
- ✅ Higher efficiency – No energy loss from ducts. This makes it more energy-efficient.
- ✅ Zoning capabilities – Each room gets its temperature control. No more fights over the thermostat!
Cons Of A Ductless System
- ❌ Visible indoor units – Some homeowners don’t like the look of wall-mounted air handlers.
- ❌ Higher upfront cost per unit – Each indoor unit costs more than a ducted vent, especially if you need multiple units.
- ❌ May require multiple units – If you have a large home, you might need several indoor units to cover all rooms.
Which One Should You Choose?
Now that you know the differences, how do you decide? Let’s break it down further.
1. Do You Have Existing Ducts?
Yes → A ducted mini split heat pump might be the better choice. You can replace your old furnace with a more efficient system without major renovations.
No → A ductless mini split system will be easier and cheaper to install.
2. How Important Is Aesthetics To You?
I want my HVAC system to be hidden → Choose ducted.
I don’t mind seeing a wall unit → Ductless could work for you.
3. How Big Is Your Home?
Larger homes → A ducted system is usually better for whole-home heating.
Smaller homes or apartments → Ductless is often the best choice.
4. Do You Want Zoned Heating And Cooling?
Yes → Ductless is great for this. You can set different temperatures in each room.
No → Ducted systems provide uniform temperatures across the house.
5. What’s Your Budget?
I want lower upfront costs → Ductless is typically cheaper to install.
I can invest more now to save in the long run → Ducted may be worth it for larger homes.
