If you’re weighing up a ductless heat pump vs. a ducted heat pump for your home in Duncan or the surrounding area, you’re not alone. It’s one of the most common questions homeowners on Vancouver Island ask when it’s time to upgrade their heating and cooling system.
Both systems are efficient, versatile, and well-suited to BC’s mild climate – but they work differently, and the right choice depends on your home’s layout, your comfort goals, and your budget.
Here’s a straightforward breakdown to help you decide. And if you’d like expert guidance tailored to your home, our heat pump services team is always happy to help.
How Each System Works
Before diving into the comparison, it helps to understand what sets these two systems apart at a basic level.
A ducted heat pump – also called a central heat pump – uses a network of ducts to distribute heated or cooled air throughout your home. It connects to a central air handler and pushes conditioned air through vents in each room, similar to how a traditional furnace operates.
A ductless heat pump – also known as a mini-split – skips the ductwork entirely. It uses one outdoor unit connected to one or more indoor wall-mounted units. Each indoor unit conditions the room it’s installed in directly, with no ducts involved.
Ductless Heat Pump vs Ducted Heat Pump: The Key Differences
Here’s how these two systems compare at a glance:
Ductless Heat Pump:
- No ductwork required
- Room-by-room zoned control
- Lower installation complexity
- Ideal for older homes, additions, and suites
- Moderate upfront cost
- Very high efficiency
Ducted Heat Pump:
- Requires existing or new ductwork
- Whole-home coverage from a single unit
- Higher installation complexity if no ducts exist
- Ideal for newer homes with existing ductwork
- Higher upfront cost without existing ductwork
- High efficiency
Benefits of a Ductless Heat Pump
For many homeowners in the Duncan to Nanaimo corridor, a ductless system is the most practical choice – especially in older homes that were built without any ductwork.
Here’s why ductless systems are so popular on Vancouver Island:
No ductwork needed. Installation is faster and less invasive. There’s no need to open up walls or ceilings to run ducts throughout the home.
Room-by-room control. Each indoor unit operates independently, so you can heat or cool only the spaces you’re actually using. This can make a real difference to your energy bills over time.
Flexible placement. Units can be installed in bedrooms, living rooms, basements, garages, or home additions – anywhere that needs reliable temperature control.
Quiet operation. Ductless systems are known for running quietly, which most homeowners notice and appreciate.
High energy efficiency. Because there are no ducts to lose heat through, ductless systems tend to perform very efficiently. According to Natural Resources Canada, heat pumps can deliver up to three times more heat energy than the electricity they consume.
Westisle Heating & Cooling installs and services a full range of ductless systems for homes and businesses across Vancouver Island.
Benefits of a Ducted Heat Pump
If your home already has ductwork in place, a ducted heat pump is well worth considering.
Whole-home coverage. A ducted system heats and cools every room through a single centralized unit – no individual wall-mounted units required in each space.
Cleaner aesthetic. With the air handler tucked away and only vents visible, many homeowners prefer the look of a ducted setup.
Well-suited to larger homes. Ducted heat pumps can handle larger floor plans where multiple ductless units might otherwise be needed.
Easy transition from an existing furnace. If you’re replacing an older gas furnace and already have ducts running through your home, upgrading to a ducted heat pump is a natural next step.
Which System Is Right for Your Home?
Choosing between a ductless heat pump vs ducted heat pump really comes down to your home’s current setup and what matters most to you.
A ductless system is likely the better fit if:
- Your home doesn’t have existing ductwork
- You want zoned, room-by-room temperature control
- You’re heating a specific area like a basement suite, sunroom, or addition
- You want a faster, less disruptive installation
A ducted system may be the better fit if:
- Your home already has ductwork installed
- You prefer a single centralized system for whole-home comfort
- You want a cleaner look with no wall-mounted units
- You’re replacing an existing central heating system
It’s also worth knowing that some homeowners use a combination of both – a ducted system for the main living areas and a ductless unit for a space that doesn’t tie into the central ductwork.

Frequently Asked Questions
What is the main difference between a ductless and a ducted heat pump?
A ductless heat pump uses wall-mounted indoor units and requires no ductwork, while a ducted heat pump distributes air through a network of ducts connected to a central air handler. Ductless systems offer room-by-room control, while ducted systems provide whole-home coverage from a single unit.
Is a ductless heat pump more efficient than a ducted one?
Ductless systems are often more efficient because there are no ducts to lose heat through. That said, both types are significantly more efficient than traditional heating methods. The right choice depends more on your home’s layout and needs than on efficiency alone.
Can I add a ductless heat pump if I already have ductwork?
Yes. Some homeowners install ductless units even when ductwork exists – for example, to condition a basement suite, workshop, or addition that isn’t connected to the main system.
Are there rebates available for heat pump installations in BC?
Yes. The BC Better Homes Energy Savings Program offers rebates to help offset the upfront cost of eligible heat pump installations. Ask the Westisle team for details on what may apply to your project.
How often should I have my heat pump serviced?
Most manufacturers and technicians recommend servicing your heat pump at least once a year. Regular maintenance helps maintain efficiency, extend the system’s lifespan, and catch small issues before they turn into costly repairs.
