Heating, Cooling & Ventilation

Ducted or hydronic networks distribute conditioned air or water throughout the building from a single plant. They suit full-home upgrades and larger commercial projects where discreet grilles or radiators are preferred over visible units.

Roof-mounted collectors harness free solar energy to pre-heat water or boost space heating. Pairing solar with a high-efficiency heat pump can lower annual running costs by 40% or more.

Electric or hydronic pipes embedded in the slab create radiant warmth that rises evenly from the floor-ideal for polished concrete, tiles or timber overlays.

Inverter technology allows modern heat pumps to both heat and cool with impressive COP ratings. Multi-split and VRF options provide room-by-room control.

From clean-burning wood inserts to contemporary gas fires, a fireplace offers ambience and peak-load heating, especially in alpine regions.

Balanced or positive-pressure ventilation replaces stale indoor air with filtered outside air. Many units incorporate mechanical ventilation heat recovery cooling cores that reclaim up to 90% of outgoing heat, reducing demand on primary HVAC equipment.

Energy-efficient fans improve air circulation, destratify warm air in winter and offer low-cost summer relief.

Whether cylinder-based or instantaneous, efficient water heaters complete the comfort package and can be integrated with solar or heat-pump technology.

• Climate zone: The same unit that copes fine in Auckland humidity may struggle in Queenstown frost. Always check operating temperatures.
• Building envelope: Well-insulated, airtight homes can downsize plant and prioritise ventilation, while older villas may need higher kW capacity.
• Energy source & running cost: Compare electricity, gas, biomass and solar inputs. Look at total cost of ownership, not just upfront price.
• Compliance: Ensure products meet the NZ Building Code, particularly Clause G4 Ventilation.
• Controls & smart integration: Wi-Fi thermostats and BMS connectivity enable zoning, scheduling and energy tracking.
• Aesthetics & acoustics: Concealed ducting, low-profile grilles and quiet decibel ratings protect the design intent and occupant comfort.

Always engage a certified HVAC installer who understands local regulations and the nuances of each product line. For heat pumps, correct refrigerant charge and outdoor unit placement will safeguard performance. Fireplaces must be installed to AS/NZS 2918 with appropriate flue clearance. Balanced ventilation should have its ductwork insulated and properly commissioned to avoid pressure imbalances. Regular servicing-including filter changes, system flushes and flue sweeps-extends lifespan and preserves warranties.

Indicative supply-and-install costs range from $3,500 for a single split heat pump to $25,000+ for a full ducted, multi-zone fit-out. Lead times can stretch to 8–10 weeks in peak season, so engage suppliers early. Many ArchiPro partners offer turnkey packages and finance options to smooth cash flow.
