In Dunedin's cold winters, sizing is everything. A unit that's too small will struggle and ice up on frosty mornings, while one that's too big can short-cycle and feel uneven. A good installer assesses your room, insulation and exposure rather than offering one-size-fits-all.
Decide whether a single high-wall unit, a multi-split, or a ducted whole-home system best suits your home, and confirm the quote covers electrical work, pipe runs, brackets, drainage and any ceiling work. Ask who handles servicing and warranty issues after the install.
It depends on the heat pump type (high-wall vs ducted), home layout, access, electrical requirements, and whether you're replacing an old unit. Get an itemised quote that confirms what's included.
Ducted can be a great option for whole-home comfort, but it's a bigger design and install job and needs proper planning. Some Dunedin providers explicitly offer ducted systems, it's often worth considering for a new build or full renovation.
Not always, but accredited installers can be important for warranty conditions and brand-specific standards, and several Dunedin providers promote accreditation and warranty benefits. It's worth confirming for peace of mind.
It depends on the room size, ceiling height, insulation and how exposed the space is, and Dunedin's cold winters mean sizing up is often wise. A good installer will measure and recommend a unit with enough capacity to heat comfortably on the coldest mornings without short-cycling.
The unit has likely entered defrost mode, reversing its cycle to melt ice off the outdoor unit. This is normal in Dunedin winters, don't turn it off, as it will resume heating automatically once the ice has cleared.
Yes. Regular cleaning and maintenance helps efficiency, air quality and reliability, and keeps the warranty valid. In Dunedin, an annual clean before winter is sensible. If the unit smells, leaks or struggles to heat, get it checked rather than running it harder.
