Once you have decided on a heat pump, the next question is how it delivers heating and cooling: through a central ducted system or through ductless mini-split heads. The best answer depends largely on whether your home already has ducts.
How each configuration works
A ducted heat pump connects to a central air handler and distributes conditioned air through the same kind of ductwork a furnace uses. A ductless, or mini-split, system mounts indoor heads directly in the rooms they serve, each connected to an outdoor unit, with no ducts at all.
Best fit: does your home have ducts
If your home already has good ductwork, a central ducted heat pump is often the simplest path, because it reuses what you have and conditions the whole home from one system. If your home has no ducts, such as a home with baseboard or radiant heat, ductless avoids the cost and disruption of adding ductwork.
Zoning and comfort
Ductless shines at zoning: each head can be set to a different temperature, so you condition only the rooms you use and keep bedrooms and living spaces independent. A ducted system heats and cools the home more uniformly and hides the equipment out of sight.
Cost, efficiency and appearance
Ductless systems avoid duct losses and can be very efficient, but the indoor heads are visible on the wall. Ducted systems are invisible in the living space but lose some efficiency through the ducts, especially if the ductwork is leaky or runs through unconditioned space.
A common hybrid
Many homes use a mix: a ducted system for the main floor and a mini-split for an addition, a finished basement or a converted attic that the ducts never reached well.
Frequently asked questions
Is ductless or ducted more efficient?
Ductless avoids duct losses and can be very efficient, while ducted efficiency depends on how well the ductwork is sealed and insulated. Both can perform excellently when sized and installed correctly.
Can I add a heat pump without ducts?
Yes. A ductless mini-split is designed for exactly that situation and is a popular option for homes with baseboard or radiant heat.
Do mini-split heads look bulky?
The indoor heads are visible on the wall or ceiling, though modern units are slim. If hidden equipment is a priority, a ducted system keeps everything out of sight.
