Make Your Home More Energy Efficient

Thinking about upgrading your home’s heating, cooling or ventilation?

The right home improvements can make your living spaces more comfortable, help manage energy use and support a healthier indoor environment. Depending on the improvements you choose and your bank’s lending criteria, you may also be able to access a sustainable home loan with a reduced interest rate.

Some New Zealand banks offer special finance options for eligible home energy improvements, with rates ranging from 0% to 1% for qualifying loans. Availability, eligible products and repayment terms vary between banks.

HVAC NZ can help you explore the right heating, cooling or ventilation solution for your home.

Upgrade Your Home. Explore Your Finance Options.

Improving your home doesn’t always mean undertaking a major renovation. A carefully selected heating, cooling or ventilation upgrade may help you create a more comfortable and energy-conscious home.

Depending on your property’s needs, you could consider:

Heating and cooling
Explore heat pump options designed around your home’s layout, room sizes and comfort requirements.

Home ventilation
Improve airflow and help manage excess moisture with a ventilation solution suited to your property.

A more efficient home environment
Consider how heating, cooling and ventilation work together to support comfort and indoor air quality.

Finance eligibility depends on the specific product or improvement, your bank’s criteria and the terms of the loan.

Could You Qualify for a Sustainable Home Loan?

Several major New Zealand banks offer home energy loan options to eligible existing mortgage customers. Depending on the bank, these may provide access to low-interest or interest-free borrowing for approved home improvements.

For example, some sustainable home loan products have offered interest rates of 0% to 1% for a limited period. The amount available, eligible improvements and loan conditions differ between lenders.

Before making a decision, check whether your proposed heating, cooling or ventilation upgrade qualifies under your bank’s current offering.

Your bank is the best place to confirm your eligibility, available interest rate, fees and repayment requirements.

Frequently Asked Questions

Can I use a sustainable home loan to install a heat pump?

Possibly, but it depends on the bank and the specific loan product. Eligibility can vary according to the type of heat pump, its intended use and the lender’s approved improvements. Check with your bank before assuming your proposed installation qualifies.

Can ventilation systems or extractor fans qualify?

Some home energy loan products include eligible ventilation systems and extractor fans. However, the exact requirements differ between lenders, so confirm that your proposed upgrade meets the relevant criteria.

Do all New Zealand banks offer 0% interest finance?

No. Finance products, interest rates, lending limits and repayment periods vary. Some banks offer reduced-interest options, while others may offer interest-free finance for qualifying improvements. Offers and conditions can change.

Does HVAC NZ provide the loan?

No. HVAC NZ provides heating, ventilation and air-conditioning solutions. Finance is arranged directly with your chosen bank or lender, which determines eligibility and approves or declines applications.

What happens when the low-interest period ends?

The interest rate may revert to a standard home loan rate or another rate specified in the loan agreement. Review the repayment schedule and understand the potential cost after any promotional period before proceeding.
