MiHT is right for you if...

your heat pump, ventilation, or solar is not performing the way it used to
Your solar is generating less than it used to. Your heat pump or ventilation is not working as well as it used to, or has started making sounds it never made before. There is a musty smell when a system runs. Condensation is appearing where it did not before. These are not signs of systems that need replacing. They are signs of systems that need professional attention.
you want your systems looked after by one company
Heat pump, ventilation, solar: most homeowners manage these separately, with different companies, different schedules, and different invoices. MiHT looks after all three in a single visit. One booking, one technician, one report. Whether you own one property or several, we make the whole process simple.
someone in your home is sensitive to air quality
Filters catch what is visible, but mould, bacteria, and allergens accumulate deeper inside heat pumps and ventilation systems where regular cleaning cannot reach. A professional service removes what you cannot see and gives you a written record of what was found and what was done.
you want to protect a system that cost thousands to install
Heat pumps, ventilation systems, and solar panels are significant investments. Neglect them and they fail years earlier than they should. The components that cause premature failure are exactly what a professional service addresses. Maintenance costs a fraction of replacement.

Maintained, Not Replaced

Your heat pumps, ventilation, and solar systems need ongoing care. Not a company looking for reasons to replace them.
‍
Most providers that service systems also install them. That conflict shapes every recommendation you receive. A provider who only does maintenance has no reason to tell you anything other than the truth.

Not sure if you need a service or a repair? After we assess your system, you will know exactly where you stand.

The MiHT Care Protocol.

Every MiHT visit follows the same five-stage process. It was built around a gap we kept seeing in the industry: homeowners paying for a service with no way to know what they actually got, or whether their systems were any better for it.

PLAN

You choose which systems you want maintained;  heat pump, ventilation, solar, or all three.

You see exactly what is included and what it costs before you commit. Book online anytime. Instant confirmation.

UNCOVER

Before we start, we check your system thoroughly. If there is existing damage, a fault, or anything that affects how we proceed, you will know about it upfront.
‍
We also take photos and note the condition of everything we can see. That snapshot becomes your baseline. When the job is done, you have a clear before and after record of your system.

RESTORE

We carry out a comprehensive maintenance service on the system you have booked, following a documented checklist built on industry best practice.
‍
Every step is completed in full, following a documented checklist built on industry best practice. If a fault is found beyond what the service covers, it is documented with photos and a separate repair quote is provided before any further work begins.

REVIEW

Once the service is complete, you receive a written condition report with before and after photos of every system we serviced.

You can see exactly where your systems started, what was done, and how they improved. Any issues uncovered are documented clearly so there are no blind spots..

PROTECT

For annual plan customers: We present you with a MiHT Care Plan, ongoing scheduled maintenance so your systems never return to where they were. We manage the scheduling, the reminders, and the next service.

For one-off customers: We set you up with a reminder so you know when your systems are due for their next service. A year from now, you'll get a prompt to rebook,  no obligation.

What you can expect from every visit.

After every visit, you get a full written report with before and after photos. You will see exactly what we found, what we did, and what to keep an eye on.

We do not install systems. Your service recommendation is based on one thing; what your systems actually need.

Every service is covered by $2M Public Liability insurance.

Common questions about home energy system maintenance in Auckland.

Will a clean actually fix my problem, or do I need a new unit?

In most cases a professional service resolves the issue. Reduced performance, unusual sounds, musty smells, and poor airflow are usually caused by accumulated dirt and grime rather than mechanical failure. Every MiHT visit begins with a thorough assessment, we will tell you clearly whether the issue is something a service will resolve or whether a repair or replacement is needed. There is no financial incentive for us to recommend a replacement.

Do you service all brands?

Yes. MiHT is brand agnostic. We service all makes and models of heat pumps, ventilation systems, and solar panels including Mitsubishi, Daikin, Panasonic, Fujitsu, and others. Our recommendations are based on what your system needs, not on any manufacturer relationship.

How often should home energy systems be serviced?

For most Auckland homes, an annual professional service is the right interval for heat pumps and ventilation systems. Solar panels benefit from a clean once or twice a year depending on your location and local conditions. The Home Energy Health Assessment will give you a personalised recommendation based on your specific situation.

How do I pay?

You pay securely online. We will send you a payment link once the service is complete. You can store your card details for fast checkout on future visits. No cash, no bank transfers, no chasing invoices.

Do I need to be home during the service?

You do not need to be present for the entire visit. We do ask that someone is available at the start so the technician can confirm access and discuss anything relevant before work begins. On the day of your service you will receive a live tracking link so you know exactly when to expect your technician. Most services are completed within a few hours.

 I manage rental properties. Can MiHT service multiple properties?

Yes. We work with property managers and private landlords across Auckland, providing scheduled maintenance, documented service records, and condition reports for heat pumps, ventilation, and solar across multiple properties. One provider, one invoice, no coordination required. Contact us to discuss your portfolio.

What is included in a MiHT Care Plan?

A MiHT Care Plan provides scheduled annual or six-monthly maintenance for your heat pumps, ventilation, and solar systems. Each visit follows the MiHT Care Protocol and ends with a written condition report. Care Plan customers have their full service history saved and receive priority scheduling. Pricing starts from $249. See the Care Plans page for full details.

How do I book?

Book your service online, 24 hours a day. Select your system type, choose a time that suits you, and receive instant confirmation. On the day of your service you will receive live GPS tracking of your technician so you know exactly when to expect them.

Can I cancel or reschedule?

Yes. You can cancel or reschedule through the link in your booking confirmation. We ask for 24 hours notice for any changes.

Ready to find out how your systems are performing?

Turn systems you are not sure about into ones you know are running right. The Home Energy Health Assessment takes about three minutes and tells you exactly where to focus.
