Heat Pump Questions, Answered

A single high-wall heat pump supplied and installed in Christchurch typically ranges from around $2,000 to $5,000, depending on the size and brand of unit and how straightforward the install is. Ducted, multi-room and whole-home systems cost more. Every home is different, so the only accurate number is a quote for your place. Request a free, no-obligation quote and we'll price it for you.

The right size depends on the room's floor area, ceiling height, insulation, window size and which way it faces. An undersized unit struggles in a Canterbury cold snap; an oversized one wastes money. We measure up and size it properly as part of a free on-site assessment, so you get a heat pump matched to the room rather than a guess.

Yes. Modern heat pumps heat efficiently even in hard frosts, but only if you choose a model rated for cold climates and size it correctly. Canterbury gets sharp overnight frosts, so we specify units built to keep performing at low temperatures and position the outdoor unit to cope with frost. This is exactly the sort of local detail a good installer sorts out for you.

Daikin, Mitsubishi Electric and Fujitsu are all excellent, reliable brands and we install and service all of them. The best choice depends on your home, your budget and the features you want rather than the badge. We'll recommend the right model for your situation instead of pushing one brand.

A well-installed, regularly serviced heat pump usually lasts around 12 to 15 years, often longer. Keeping up annual servicing and washing the filters is the single biggest thing you can do to extend its life and keep it running efficiently.

A high-wall (split) unit mounts on the wall and heats or cools one room or open-plan space. It's the most affordable option and the quickest to install. A ducted system is hidden in the ceiling and pushes air through vents into several rooms, giving even, whole-home comfort and a tidier look for a higher cost. We'll talk through which suits your home and budget on a free on-site assessment.

No, modern heat pumps are very quiet. The indoor unit runs at roughly 19 to 30 decibels on normal settings, quieter than a library, and the outdoor unit sits around 40 to 55 decibels. We also position the outdoor unit carefully to keep noise away from bedrooms and neighbours.

Most single high-wall heat pump installations are completed within a day. Ducted and multi-room systems take longer, usually one to a few days depending on the layout. We'll give you a clear timeframe with your quote so you know what to expect.

We recommend a professional service every one to two years to keep it running efficiently and to protect your warranty. In between, wash the filters every one to two months, more often if you have pets or run it hard. We offer annual service plans so it's looked after without you having to remember. Regular maintenance is also what keeps your 5-year workmanship warranty valid.

Yes, we back our work. Chill Air provides a 5-year workmanship warranty on our installations, on top of the manufacturer's warranty on the unit itself.
