Solutionair is a New Zealand-based leader in residential ventilation, heating, and cooling, helping homes perform at their best. We work closely with homeowners, architects, designers, and builders to create integrated HVAC solutions that deliver healthy air, consistent comfort, and long-term efficiency.

Modern homes are airtight, which improves energy efficiency—but it also makes air quality, moisture control, and thermal comfort critical from day one.

Our approach is design-led and evidence-based. Using thermal modelling and system planning, we tailor solutions to each home’s layout, orientation, construction, and lifestyle, ensuring ventilation, heating, and cooling work together as a seamless system.

Ventilation is at the core of what we do. Our Mechanical Ventilation with Heat Recovery (MVHR) systems continuously deliver fresh, filtered air while removing moisture and stale air. In winter the MVHR recovers heat from the outgoing air and in summer it takes advantage of cool indoor air to maintain comfort without wasting energy. Properly integrated, these systems improve indoor air quality, protect the building, and reduce reliance on mechanical heating and cooling.

From early planning to installation and commissioning, Solutionair provides guidance, technical clarity, and support to ensure every system performs as intended. The result? Homes that are healthier, more comfortable, and better to live in—every day of the year.
