Commercial Heat Pumps & HVAC
For Waikato offices, retail, warehouses and light industrial
Comfort for the people who keep your business running
Commercial HVAC is a different game from residential. Larger heat loads, more occupants, longer operating hours, and downtime that costs you money. A system specced wrong runs your power bill up and leaves staff complaining all year.
Airmax engineers commercial HVAC properly — proper heat load calculations, the right brand for the application, and installation scheduled around your operating hours. We work with Waikato offices, retail shops, hospitality venues, warehouses, clinics, and schools.
Commercial sectors we work with
Offices
Open-plan and partitioned office spaces — multi-split or ducted with zone control so staff in each area can manage their own comfort.
Retail
Shops, showrooms, hospitality — quiet operation, fast recovery, and customer-friendly aesthetics. Wi-Fi control for remote management.
Warehouses & light industrial
Large-volume spaces with high-capacity ducted or VRF systems. Dehumidification and ventilation integrated where needed.
Healthcare & education
Clinics, daycare, schools — quiet, filtered air with Lossnay ventilation for healthy indoor air quality.
How commercial installation works
Site assessment & needs analysis
We visit your premises, measure heat loads, assess ductwork, and understand how your team uses the space. Open-plan office, retail showroom, warehouse — each gets different specs.
System design & fixed quote
We engineer the right system — single-zone, multi-split, ducted, or VRF — and provide a fixed quote with timeline. No vague estimates.
Installation & commissioning
Licensed refrigeration and electrical work, scheduled around your operating hours where possible. We commission, test, and walk your team through the controls.
Maintenance & support
We offer scheduled servicing plans to keep commercial systems efficient, within warranty, and compliant with building WOF requirements.

Commercial HVAC questions
How much does commercial heat pump installation cost in NZ?
Commercial heat pump installation in NZ typically starts from $4,500 for a single-zone office and scales to $25,000–$80,000+ for ducted or VRF systems covering large retail, warehouse, or multi-storey premises. Pricing depends on capacity required (kW), ductwork complexity, controller integration, and after-hours installation requirements. We provide fixed quotes after a free site assessment.
What size heat pump does a commercial space need?
Commercial heat pump sizing is based on heat load calculations — typically 100–150 watts per square metre for offices, higher for retail with glass frontage or warehouses with poor insulation. A 200m² open-plan office usually needs 20–30kW of cooling/heating capacity, often split across multiple indoor units. We measure on site and design the system around your specific space, not rule-of-thumb estimates.
Can you install commercial HVAC outside of business hours?
Yes. We routinely schedule commercial installs after-hours, on weekends, or during quiet trading periods to minimise disruption. Tell us your operating constraints during the quote and we'll work the installation timeline around them — including phased installations across multiple visits if the system is large.
Do commercial heat pumps qualify for tax depreciation?
Yes. Commercial heat pumps and HVAC systems are depreciable business assets under IRD rules, typically over 15.5 years (DV) or 10 years (SL) for fixed building services. We provide GST invoices with the system breakdown so your accountant can claim correctly. Confirm specifics with your accountant or IRD.
How often should commercial HVAC be serviced?
Commercial HVAC systems should be serviced at minimum once a year, with quarterly checks recommended for retail, hospitality, healthcare, and any heavy-use environment. Regular servicing keeps the system efficient (reducing power bills), preserves manufacturer warranty, and is often a requirement of building WOF and lease agreements.
Which commercial heat pump brands do you install?
We install commercial systems from Mitsubishi Electric, Daikin, Hitachi, Fujitsu and Panasonic — including their City Multi VRF, PEA splittable, and ducted ranges. We recommend the right brand based on your space, budget, and existing infrastructure rather than pushing a single supplier.
Can you integrate with a Building Management System (BMS)?
Yes. We can integrate Mitsubishi Electric, Daikin, and other commercial-grade HVAC with your existing BMS or smart-building platform via standard protocols (BACnet, Modbus). For smaller commercial spaces, AirTouch 5 or brand-native Wi-Fi controllers provide centralised control without a full BMS.
