Heat Pump Installation in Invercargill Done Right

Heat pump installation in Invercargill means matching the unit to your home, not the biggest box on the shelf. We size it for your rooms and how well they hold heat, fit it tidily, and back our own work. Most homes get a high-wall unit sorted in a day.

What a good install actually involves

The unit on the wall is the easy bit. The part that decides whether your place is warm is the sizing and where we put things. Get that wrong and you've got a pump that runs flat out, struggles through a hard frost, and costs more to run than it should.

We start by looking at the room, how it faces, and how well it holds heat. An old single-glazed villa in Hawthorndale loses warmth a lot faster than a sealed newer home in Rosedale, so the same room needs a bigger unit in one than the other. If you want to sanity-check numbers yourself, our heat pump sizing calculator gives you a rough idea before we visit.

On install day we mount the indoor head, run the pipework and drain neatly, set the outdoor unit on a solid base off the ground, and test it properly before we leave. A tidy job matters more than the sticker price, because a rushed install is where the leaks and cold spots come from.

Sizing for Invercargill homes and our long winters

Our heating season is long and the southerlies are cold and damp, so a heat pump here works harder than one up north. That's why the right size beats brand or grunt every time. Too small and it can't keep up on the coldest mornings. Too big and it short-cycles, which wastes power and leaves the room feeling clammy.

Older villas across the valley suburbs need more careful thought than sealed newer builds. If you've got high ceilings, a draughty hallway, or an open-plan living area, that changes the pick. It's worth reading through the types of heat pump so you know what suits a single room versus a whole floor.

High-wall units, and when to look at ducted

For most Invercargill homes a high-wall unit in the main living area does the job well and costs the least to fit. It's the workhorse of home heating down here and easy to service later.

If you want even heat through several rooms, or you're doing up a whole house, ducted heat pump systems are worth a look. They cost more up front and need ceiling or floor space for the ducting, so they're not right for every home. We'll tell you straight whether your place suits one or whether a high-wall or two makes more sense.

Cost, and the Warmer Kiwi Homes grant

Price depends on the unit, how many rooms you're heating, and how tricky the run is to the outdoor unit. We'll give you a clear quote with no surprises. You can see what shapes the installation cost before you commit.

The Warmer Kiwi Homes grant can cover a big share of a heat pump for eligible homeowners, up to a set cap. It's run by EECA and you apply through them, not us. We're not an EECA provider, so we can't administer the grant, but we're happy to fit a unit once you've sorted your funding.

After we've installed it

A heat pump lasts longer and runs cheaper with a clean now and then. We handle heat pump servicing and repairs for the units we've installed ourselves. We don't service or repair other companies' installs, so if we didn't fit it, we're not the ones to call for a service.

That policy is also why we're picky about doing the install properly in the first place. When we put our name on it, we're the ones looking after it down the track.
