Out with the old, in with the efficient.
If your heat pump is no longer doing its job—costing more to run, heating less effectively, or making strange noises—it might be time for a change. In this Christchurch guide, we’ll help you figure out when to replace your old heat pump, what to expect during the process, and how to choose the right replacement for your home.
Why replace an old heat pump?
Most heat pumps have a lifespan of around 10–15 years. Over time, they lose efficiency and start costing you more in repairs and power bills.
Here in Christchurch, where temperatures can drop quickly in winter, a well-functioning heat pump makes a big difference. You should consider a replacement if:
🔧 Your heat pump needs frequent repairs
🔌 Your power bills have increased noticeably
🌡️ The unit isn’t heating or cooling like it used to
🔊 It’s noisy or blowing strange-smelling air
⏳ It’s over 10 years old and generally underperforming
