If you’re considering switching to a low-carbon heating system in Chislehurst, one of the most common questions is: how long does an air source heat pump actually last?
At NCC South East, we’ve installed, serviced, and repaired heat pumps across Bromley, Chislehurst, and West Wickham. Here we’ll explain the typical lifespan of a heat pump, how regular servicing helps, and when it may be time to repair or replace your system.
Average Lifespan of Air Source Heat Pumps
A well-installed and regularly maintained air source heat pump can last 20-25 years. That’s similar to, or longer than, the lifespan of a traditional gas boiler – but with far greater efficiency and lower carbon emissions.
Premium models from manufacturers like Mitsubishi, Panasonic, Samsung, Grant, and Midea are designed for durability, and many come with warranties of up to 7 years (extendable with annual servicing).
Why Servicing Matters
Just like a car, your heat pump needs routine care to keep it running smoothly. We recommend a yearly service for all Chislehurst homeowners. Regular maintenance helps to:
- Prevent breakdowns by catching small faults early
- Keep efficiency levels high (reducing running costs)
- Protect your manufacturer’s warranty
- Extend the overall lifespan of your system.

When to Repair – and When to Replace
Over time, components such as fans, compressors, or sensors may need repair. In many cases, these are quick fixes that restore your system to complete working order.
But there are times when replacement may be more cost-effective:
- Frequent breakdowns – if you’re calling an engineer several times a year.
- Inefficient performance – rising bills or poor heating despite servicing.
- Age – if your heat pump is over 15 years old, a new model may deliver better performance and lower running costs.
Our engineers will always provide honest advice – whether a targeted repair or full replacement is the best option for your Chislehurst home.
