Dedicated project support

For larger projects, Daikin UK Service department offers complete Project Support from the point of order to system handover. Our service engineers will assist you throughout the project, providing a dedicated contact for technical queries and support, installation checks and commissioning. As part of our Project Support service, we conduct surveys during the installation to ensure it is installed to our specification and rules, witness the strength/pressure test on the DX side, evacuate the systems, charge with any additional refrigerant and configure any ITM controls prior to commissioning.

Maintenance contracts

Commercial customers

If you would like Daikin UK to support you with commercial maintenance contracts, we can offer a full service package, including 24 hour support, for account holding customers.


Domestic heating customers

Daikin UK offers comprehensive heat pump maintenance as a premium after care service for Daikin Altherma systems. All parts, labour and call-outs are covered in the unlikely event of a heating or hot water failure (subject to T&Cs).

For total comfort and peace of mind, this heat pump maintenance package also includes an annual maintenance visit, to help keep your customers’ systems running efficiently throughout the year and minimise the risk of any breakdowns.

Daikin UK also offers a basic heat pump maintenance package, which entitles you to an annual maintenance visit, during which our engineer will ensure that your Altherma heat pump is operating within the optimum conditions to maximise energy efficiency. Any potential issue can be dealt with by a Daikin engineer. You will also be entitled to a discount on the cost of spare parts and labour.


Energy monitoring and auditing

Daikin UK offers an increasing range of energy monitoring and auditing services, plus remote monitoring and prediction solutions (DNSS). Please ask your sales engineer if you have a project that you think may be suitable for including in an energy monitoring and auditing trial.
