A heat pump quote is easier to read when you know what is being priced. In Cambridge, the work starts with the room you want to warm, the wall the indoor unit will sit on, and the space outside for the outdoor unit.

The price table gives a starting range for the common sizes. The rest comes down to the details of your house and the firm you choose, so it pays to know what is included in each quote.

How to size a heat pump

What does heat pump installation cost in Cambridge?

The price table shows typical New Zealand installed prices, including GST, for a standard back-to-back install, which means the outdoor unit sits directly behind the indoor unit on an outside wall. The figures draw on published price guides from eight NZ installers and retailers.

For a typical home, match the size to the room. The small high-wall unit in the price table suits a bedroom or small room, the medium high-wall suits a lounge, and the large high-wall suits open-plan living. A ducted system covers the whole house.

If you are unsure which size fits, the heat pump sizing guide explains how room size and layout affect the choice. The ducted or high-wall guide compares those two approaches.

Heat pump cost questions in Cambridge

Does frost affect heat pump choice in Cambridge?

Frosts can occur anywhere in New Zealand, and inland and southern towns see colder winters. Check that the unit is sized for the room. The energy label shows heating at 7°C and 2°C outside and cooling at 35°C, so compare quotes on the same figures.

What warranty should I ask about?

A single Cambridge installer mentions a warranty on their website. Ask each one what the manufacturer covers, what their own workmanship cover includes, and for how long. Get the model number and those terms in the written quote so offers compare like for like.

Does it matter if an installer is an authorised dealer?

Authorised dealer status is not mentioned on any Cambridge installer's website. Ask which brands they fit, what training backs that up, and where support comes from.

Can a heat pump quote change after I accept it?

A quote must not mislead under the Fair Trading Act, including over hidden costs. If you agree to work without a set price, the Consumer Guarantees Act says you pay only a reasonable price. Ask for the scope and any assumptions in writing before work starts.
