Heat pump installation Dunedin homes stay warm through

A good heat pump install in Dunedin starts with sizing the unit to your room and how cold it actually gets, then placing it so it heats evenly. We handle the mounting, pipework, electrical and testing, and we stand behind the work we do.

Sizing a heat pump for a real Dunedin winter

The single biggest thing that decides whether your house is warm is getting the size right. A unit that's too small runs flat out on a frosty July morning and never quite catches up. Too big and it short-cycles, costs more up front and doesn't dehumidify well.

Dunedin makes this harder than most places. High-ceilinged villa rooms hold a lot of air, and older homes with minimal wall insulation lose heat fast. We size to hold output when it's sub-zero outside, not to a mild afternoon figure. If you want a rough idea before we visit, our heat pump sizing calculator gives you a starting point, and we'll confirm it on site.

Different rooms and layouts suit different gear too. A single open-plan living area is a different job to heating three rooms off one system, so it's worth understanding the types of heat pump before you settle on one.

What a tidy install actually involves

Most of our work is a single split installation: one indoor high wall head paired with one outdoor unit. A high wall heat pump installation is quick and unobtrusive, and for a lot of Dunedin homes it's all you need.

On the day we mount the indoor head, run the pipework and drain neatly, fit the outdoor unit, do the electrical connection, then vacuum, charge and test the system before we leave. A clean install matters more than the sticker price, because dodgy pipe runs and a poorly placed head are what leave a house cold and damp. We'll walk you through the running costs so there are no surprises, and you can see how the numbers stack up on our installation cost breakdown.

Outdoor units on hills, the coast and exposed sites

Where the outdoor unit goes changes a lot around here. On the Peninsula and out at Macandrew Bay, salt in the air corrodes cheaper units faster, so placement and the right model matter. Exposed Taieri and Outram sites cop the wind, and steep hill-suburb access in places like Wakari and Maori Hill can make getting gear to the back of a section a job in itself.

We look at all of that when we quote, so the unit sits somewhere it's protected, easy to service and not blasting cold air at your front door. We cover the full range of areas we install across Dunedin, from Musselburgh flats to hillside villas.

The brands we fit and looking after it later

We fit gear we trust to handle Dunedin cold, including Mitsubishi Electric heat pumps, which hold their output well on the coldest mornings.

Once it's in, a heat pump needs the odd clean and check to keep running efficiently. We only service and repair the heat pumps we installed ourselves, so keeping up with heat pump servicing on our own installs is straightforward and we know the system inside out.

If money's tight, the Warmer Kiwi Homes grant can cover a big chunk of a heat pump for eligible homeowners. You apply through EECA directly, and it's worth checking before you commit.
