Upper Hutt is sheltered from the worst of the wind, but that shelter lets cold air settle on still nights. NIWA's climate station at Wallaceville averages about 24 air frosts a year, while Kelburn in the city averages none, and Wallaceville also logs more fog and more rain days than the other stations in NIWA's regional comparison.
The town is growing fast, and that shapes the work. New subdivisions at Wallaceville, Riverstone Terraces and Silverstream are full of airtight, well-insulated homes that suit ducted or multi-room systems from day one. Older weatherboard houses in Trentham, Ebdentown and Heretaunga, and bush-edged properties out towards Akatarawa, Mangaroa and Whitemans Valley, often still rely on a log burner. These are the nine installers we'd call first.
How to tell your Upper Hutt heating isn't keeping up
Cold, still nights are where a weak heating setup shows itself. If two or more of these ring true, start getting quotes while the weather is still mild.
- On frosty mornings the house is colder inside than it should be, and the heat pump runs flat out for an hour before anyone feels a difference.
- The outdoor unit sits in a hollow or on the shady side of the house and is often iced up or wrapped in fog when you leave for work.
- Windows stream with condensation through the long, damp stretch from late autumn to early spring.
- You still light the log burner every evening, but only the lounge benefits and the bedrooms stay chilly.
- You've moved into a new build and the single heat pump that came with it can't keep the upstairs bedrooms warm. Better winter settings can help, but sometimes the system is simply too small.

Choosing an Upper Hutt installer: what to check
Ask how the unit will perform on the coldest mornings. Heat pumps lose output as the outdoor temperature falls, so in a frosty valley it's worth asking for the rated heating capacity at low temperatures, not just the headline figure. Our heat pump brands guide can help.
Talk about where the outdoor unit goes. A spot out of a frost hollow, with room for defrost water to drain away without freezing on a path, helps.
In a new build, plan the heating before the plasterboard goes up. Running a ducted system through the ceiling is far easier at framing stage. Our ducted versus high wall comparison sets out the options.
In an older home, ask whether a floor console under the window would heat a cold lounge faster than a high wall unit, since warm air rises from floor level.
Finally, ask about servicing. A unit that runs hard from April to October benefits from an annual check, and our servicing guide explains what should be included.
