Even Kiwibank rewards you with cash back if you commit to a bigger upgrade. Why wait, upgrade to a Carrier or Toshiba system and invest in comfort, savings and sustainability.

Quick Tips Before You Start

Check eligibility—most of these loans require you to be an existing home-loan customer with sufficient equity.
Gather quotes—banks usually ask for professional quotes before approving the top-up.
Plan to repay—with fixed or interest-free deals, you’ll need to stick to repayments to avoid later rate increases.
Assess your needs—figure out what system is best for your home; Toshiba heat pumps are an excellent starting point!
