Ducted in Invercargill
What to know about ducted heat pumps in Invercargill
A whole-home system that is not zoned will heat unused rooms through a Southland night. That is a running-cost problem, not a comfort win.
Ask for heating capacity at −7 °C or lower. A unit that only looks good at 7 °C will disappoint you. Wind and rain make outdoor placement and a decent drain part of the job.
Is a ducted right for your home?
A quick way to tell before the installer visits.
A good choice when
A new build or a gut renovation
The ceiling can be designed for ducts, returns and service access. This is when ducted makes sense.
You want the hardware invisible
No heads on the walls. Zoning so the guest room is not on the same setpoint as the lounge.
Consider another type when
A villa with no roof space
Forcing ducts into a shallow ceiling is a noisy, expensive disappointment. Use multi-split or several high-walls.
You need the grant this year
Warmer Kiwi Homes is high-wall only. Do the living area first if funding matters.

Ducted heat pumps in Invercargill: questions
Is a ducted the right heat pump for Invercargill?
Ducted in Southland is a larger, newer-home conversation. Most villas should stay on properly sized high-walls. A local installer confirms the type and size on site.
Can I retrofit a ducted heat pump into an older house?
Sometimes, if the roof space is deep enough and there is a return-air path. Many villas and low-pitch 70s houses cannot take it cleanly. The installer should look before you budget for it.
Is ducted cheaper to run than several high-walls?
A well-zoned ducted system can be efficient. An unzoned unit heating empty bedrooms is not. Running cost is about zoning and insulation, not the word ‘ducted’.
