Professional Heat Pump Installation Services in New Zealand
NZ homes and businesses rely on heat pumps for efficient heating and cooling. But performance depends heavily on correct heat pump installation. A perfectly sized unit can still underperform if it’s installed in the wrong location, with poor airflow, incorrect pipe runs, or insufficient drainage planning. That’s why our installation approach focuses on comfort, efficiency, compliance, and a clean finish.
Whether you’re installing a wall-mounted split system for a bedroom, a floor console for a colder area, a ducted system for whole-home comfort, or a multi-split to cover multiple rooms, we help you choose the right setup and organise installation support.

Heat Pump Installation Process – Step by Step
Here’s how a professional heat pump installation typically works. This section is written in plain English so customers know exactly what to expect.
- Confirm the right system: Choose split, ducted, floor console, or multi-split based on room layout, insulation, and how you use your home. If you’re unsure, use our sizing guide first.
- Plan the indoor unit position: Correct airflow and location matters. We avoid placing units where airflow is blocked by curtains, tall furniture, or awkward corners.
- Plan the outdoor unit position: Stable base, good clearance, tidy pipe routing, and consideration for noise/neighboring areas.
- Pipework + drainage: Professional installation includes neat pipe runs, insulation, and a proper condensate drain plan to prevent leaks or water issues.
- Electrical connection: Safe electrical work is essential. The system must be connected correctly for reliable operation and safety.
- Vacuum + commissioning: Commissioning ensures the system is operating correctly, airflow and modes are tested, and any setup requirements are confirmed.
- Customer handover: We explain how to use modes efficiently, how to keep filters clean, and what settings are best for NZ winter and summer comfort.
