App development for HVAC companies.
HVAC companies-grade app development, shipped by people who've done it before.
Maintenance reminders, bookings and quotes with GST at 15 per cent handled automatically across your customer base.
Knows the New Zealand rules.
Apps in New Zealand English that keep working on patchy rural coverage, with personal information handled under the Privacy Act 2020.
- Serious breaches get reported
- Personal data sent offshore
- GST at 15 per cent
From one-person trades to national organisations, we find the hours :)
Quotes with GST, consent paperwork, LBP records and health and safety logs: the admin every New Zealand trade business carries.
*Illustrative example based on nine hours a week of admin. Actual results vary by workflow and business.
How the work runs
We find the one workflow costing HVAC companies the most hours, ship a working slice into production in weeks, prove it pays for itself, then harden it and hand it over.
An AI agency, minus the theatre.
*Every engagement is scoped and quoted up front. Results vary by workflow and business.
The pattern across most HVAC companies we work with.
Heating and cooling businesses run on seasonal call volume that spikes exactly when the team is already stretched.
Scheduling, callout triage, and maintenance reminders are what separate a booked-out HVAC business from a quiet one.
Small team.
Real systems.
Zero fluff.
What you get
You get a working build on your own phone early in the project, so decisions are made on the real app rather than on slides.
- iOS, Android and web from one team, on one codebase where it fits
- Backend, database and admin screens built alongside the app
- App Store and Google Play releases handled for you
- Screens designed with your staff and customers before code is written
- No annual contracts
- No AI theatre
Straight answers
What if our HVAC company doesn't have any data ready?
Most don't. Getting the data into shape - ingestion, cleaning, the lightweight contracts you need before any model is useful - is part of the engagement. For app development specifically, we typically run that work on Expo, React Native, Swift, Kotlin, Next.js, Postgres and assume messy starting conditions from day one.
Can you walk us through a comparable build?
Yes - on the first call we'll pick the closest engagement we've shipped to what you're describing and walk through the outcome, the headcount and the time it took. You get a working build on your own phone early in the project, so decisions are made on the real app rather than on slides.
What's the smallest engagement you'd take on?
A two-week paid discovery for HVAC companies that aren't sure whether the build is worth doing at all. You get a one-page write-up of what we'd build, what we'd skip, and what it would cost. About 30% of those discoveries end with us recommending you don't proceed.
Is our data kept in New Zealand?
Kiwi Dynamics hosts its own infrastructure in New Zealand, under New Zealand governance. If personal information ever has to go offshore, privacy principle 12 requires comparable protection.
Does it keep up with KiwiSaver changes?
It has to. The minimum employer contribution rose to 3.5 per cent on 1 April 2026 and rises to 4 per cent on 1 April 2028.
