In Wellington's cold, damp winters, sizing and the home's insulation are everything. A heat pump struggles in a draughty, poorly insulated villa, so the best installers assess the whole picture, room size, insulation and exposure, rather than offering one-size-fits-all, and factor in coastal corrosion and wind on exposed sites.
Decide whether a single high-wall unit, a multi-split, or a central/ducted system best suits your home, and confirm the quote covers the dedicated circuit, electrical Certificate of Compliance, pipe runs, brackets, drainage and any ceiling work. Ask who handles servicing and warranty after the install.
Standard back-to-back installations range from $2,600 to $4,500 depending on the kW rating. Complex installations requiring extended pipe runs or switchboard upgrades cost more. Ask for an itemised quote confirming what's included.
Mitsubishi Electric, Daikin and Fujitsu are considered the 'Big Three' for reliability, parts availability and warranty support in New Zealand. Panasonic is also highly rated.
Yes, but insulation is crucial. Without upgraded ceiling and underfloor insulation, heat pumps struggle in draughty homes with poor thermal performance. Many Wellington homeowners pair a heat pump with insulation improvements for the best result.
It depends on the room size, ceiling height, insulation and how exposed the space is. A good installer will measure and recommend a unit with enough capacity to heat comfortably through Wellington's cold, damp winters without short-cycling, rather than guessing from floor area alone.
It can. Salt spray can corrode the outdoor unit in exposed coastal suburbs, and wind affects placement. Coastal-grade units, sensible siting and regular servicing all help, so mention your exposure to the installer when getting a quote.
Yes. Regular cleaning and maintenance helps efficiency, air quality and reliability, and keeps the warranty valid. In Wellington's damp climate, an annual service is sensible. If the unit smells, leaks or struggles to heat, get it checked rather than running it harder.
