HEAT PUMPS
Heat Pump Replacements & Upgrades
Upgrade to a quieter, more energy-efficient heating solution designed for the way you live. Whether your current heat pump is struggling to keep up, costing too much to run, or simply reaching the end of its lifespan, ATL Heat Pumps can help you compare modern replacement options tailored to your home, comfort, and budget.
Is your heat pump leaking, noisy, or struggling to keep up?
If your system is more than 10 years old, smells musty when running, struggles to heat properly, or is costing more to run than it should, it may be time for a professional heat pump replacement or upgrade.
Older systems often become inefficient, unreliable, and expensive to maintain — especially during the colder South Island winters.
ATL specialises in heat pump replacements, upgrades, and modern heating solutions across Christchurch, Canterbury, Reefton, and the Buller District. Our experienced team will assess your current setup and recommend the right solution for your home, comfort needs, and budget.

Replacement vs upgrade
Replacement:
Replacing an older, faulty, or inefficient system with a newer equivalent or improved heating solution.
Upgrade:
Improving comfort, efficiency, control, or coverage — such as moving from a single-room system to ducted heating, ventilation, or multi-room solutions.
Not sure which option suits? That’s where we can help.
We don’t just swap units. We assess your space properly to ensure the new system is sized correctly and positioned for maximum efficiency.
