Commercial Mechanical Design & Build — Auckland & Hamilton
Design
Harrison AC’s mechanical design team works across projects of every scale — from residential homes to multi-storey commercial offices in Auckland and Hamilton. We partner with architects, builders, and project managers from the design stage, engineering ducted HVAC systems that are efficient, compliant, and tailored to the building. From concept through to completion, our design and build approach ensures every project is handled with the right expertise from day one
Build & Installation
Once the design is finalised, our installation teams bring it to life — delivering HVAC systems of every type across Auckland and Hamilton with the same precision and attention to detail as the design stage. From coordinating with builders and site managers to working around live construction schedules, we ensure every install is completed to spec, on time, and to a standard that performs for years to come
Planned Preventative Maintenance (PPM)
Our Planned Preventative Maintenance (PPM) contracts keep commercial HVAC systems across Auckland and Hamilton running efficiently and reliably. Regular scheduled servicing and inspections catch issues early — reducing downtime, protecting your unit warranties, and extending the life of your system.

We don’t just install ducted heat pump systems — we understand how to get the best out of them. Our team has spent years helping Auckland and Hamilton homeowners get more efficient, comfortable homes, and we’re happy to share that knowledge, whether you’re a customer or not.
