⏳ How long does a heat pump last?

With proper installation and regular servicing, an air source heat pump typically lasts 15 to 20 years—and often even longer. That’s comparable to, if not better than, many traditional gas or oil boilers.

At South West Plumbing, we install only trusted brands—such as Worcester Bosch—designed for long-term durability and performance.

🔧 What maintenance is required?

Heat pumps are low-maintenance compared to fossil fuel systems, but an annual service is essential to ensure:

✔ Maximum efficiency
✔ Safe operation
✔ Compliance with manufacturer warranties
✔ Long-term reliability

During a routine service, we’ll check things like refrigerant levels, filters, system pressures, controls, and performance—all to keep your system running like new.

🧰 Do I need a service plan?

While not required, a service plan like our HeatCare Renewable Plan can give you:

• Annual servicing
• Priority call-outs
• Discounted labour rates
• Peace of mind year-round

It’s an easy way to stay on top of maintenance and protect your investment over the long term.
