Annual care
An annual service helps protect your warranty, keep your heat pump running efficiently, and identify small issues before they become bigger problems.
Most manufacturers recommend or require annual servicing to support warranty requirements. Keeping your service history up to date can help if problems arise later.
Annual servicing helps your heat pump run as efficiently as possible and reduces the risk of unexpected breakdowns by identifying issues that could develop over time.
Your engineer checks key parts of the system including refrigerant, electrical components and overall operation to help make sure everything is running as it should.
