How to choose a heat pump installer in Wellington

A heat pump quote is not only a price for a unit. It is also a recommendation about sizing, placement, electrical work, drainage, pipe routes, commissioning, warranty support and what happens if something goes wrong later.

Wellington homes add their own complications: wind exposure, coastal air, older housing, difficult access, large glazing areas and very different microclimates across the region. The installer matters as much as the brand.

1. Ask who is actually assessing your property

Find out whether the person recommending the system understands refrigeration, HVAC and electrical installation. A proper assessment should consider the property and how the space is used, not just match a room size to a catalogue.

2. Ask how the heat pump was sized

Floor area is only one input. Ceiling height, glazing, insulation, layout, sun, airflow, adjoining spaces and heat loss all influence the capacity required. Oversizing and undersizing can both lead to poor results.

3. Compare the installation scope, not just the model

Two quotes for the same heat pump can describe very different installations. Check where the indoor and outdoor units will go, how pipework and drainage will be routed, what electrical work is included, how access will be handled and what the finished installation should look like.

4. Decide whether brand choice matters to you

Some installers specialise in one manufacturer while others work across several. Neither model is automatically wrong, but a multi-brand installer can compare different product ranges around the property, features and budget.

5. Check repair and servicing capability

Ask what happens after installation. Does the same business provide diagnostics, repairs and maintenance? Who helps with warranty issues? A company that can fault-find as well as install can remain useful throughout the life of the system.

6. Understand the payment and workmanship terms

Before accepting a quote, make sure you understand deposits, progress payments, the workmanship warranty and what happens if the finished installation does not match the agreed scope.

Frost Industries’ standard approach is 0% upfront, with invoicing after installation or an agreed project stage is complete, alongside our Satisfaction Guarantee terms.

7. Look for evidence, not slogans

Useful proof includes recent customer reviews, examples of completed work, clear contact details, established supplier relationships and technicians with relevant trade experience. A polished website is helpful, but it should support evidence rather than replace it.
