Hitachi Maintenance Agreements

Delta T services can offer a flexible maintenance package to suit your environment and equipment usage.

As a guideline we recommend the following maintenance schedules, for standard offices and homes twice a year is a good frequency, for shops with an open door policy four times a year is often required dependant on footfall of traffic and the location of the shop front to any busy roads.
Set Free VRF and larger systems with numerous indoor units should be maintained four times a year.

If you are a domestic customer who rarely uses their air conditioning then once a year may be sufficient.
