Most standard single-unit installations are completed in one day (3-5 hours). Multi-split or ducted systems may require 1-2 days depending on your property’s layout.

Yes. OneAir technicians service and repair all major brands including Mitsubishi Electric, Panasonic, Daikin, Fujitsu, Samsung, Hitachi, Toshiba, and more – whether we installed them or not.

Annual servicing is recommended, ideally before winter. Systems used heavily throughout Dunedin’s extended cold season may benefit from servicing every 6-9 months.

We service all Dunedin suburbs from the Peninsula to Mosgiel, North Dunedin to Brighton, and throughout wider Otago including Balclutha, Palmerston, and Waikouaiti.

Yes. We understand how critical heating is during Dunedin winters. We offer same-day repairs in most areas, subject to availability. Call 0800 663247 for urgent breakdowns.

Sizing depends on room dimensions, insulation levels (particularly important in older Dunedin homes), ceiling height, and heating requirements. Our technicians conduct proper assessments to ensure correct sizing – undersized systems will struggle in Dunedin’s cold, while oversized systems waste energy.

Yes. Modern heat pumps are designed to operate efficiently even in low temperatures. Quality systems continue heating effectively down to -15°C. Proper sizing and installation are crucial for optimal performance in Dunedin conditions.

Heat pumps are among the most cost-effective heating options. They use approximately 1 unit of electricity to move 3-4 units of heat, making them far more efficient than electric heaters. Running costs depend on usage, electricity rates, and system efficiency, but most Dunedin households see significant savings compared to traditional electric heating.

Modern heat pumps have automatic defrost cycles that prevent ice buildup. During very cold conditions, you may notice the outdoor unit periodically switching to defrost mode – this is normal operation.

Yes. New heat pumps come with comprehensive manufacturer warranties (typically 5-6 years). OneAir also provides a workmanship guarantee on all installations, and our ServicePlus Protection programme offers extended peace of mind.

Dunedin residents may be eligible for government subsidies for insulation and heating. We can advise on eligibility and help with the application process. Contact us for details.
