The brief
A busy airport car park depends on its staff offices, control rooms and plant spaces staying comfortable and running. Air conditioning that is cleaned and checked on a schedule fails less often, uses less energy and costs less to run than equipment left until it breaks.
NCP needed one dependable contractor to service a mixed estate of units from different manufacturers, on a set schedule, with every visit recorded.
What each visit covers
Every visit follows the same checklist, whatever the make of the unit.
- Outdoor units: inspect and clean the coils, check the mounting and condition, and take refrigerant pressure readings with calibrated gauges.
- Indoor units: open each unit, remove and wash the filters, and check the coil, fan and casing.
- Cassettes: remove the grille and clean the filter and fan area of ceiling cassettes.
- Condensate: check drain pumps and drain lines so water cannot back up and leak.
- Ventilation: inspect the ducted extract fans that serve plant spaces.
- Controls and safety: confirm each unit starts, runs and cycles correctly, and that isolators operate.
How the contract works
There are two planned visits a year, spaced about six months apart, so each unit is cleaned and checked before the heavy cooling and heating seasons.
Between visits, if something goes wrong, NCP has one phone number to call. The engineers who maintain the units know the site and the equipment already.
Every unit is identified by an asset ID label, so work can be recorded against the right unit.
The result
NCP gets a predictable, scheduled service with filters and coils that are cleaned every six months, which supports reliable comfort for staff and fewer unplanned breakdowns.
Why Optimal
- Any make: we maintain Daikin, Fujitsu, Mitsubishi and other manufacturers’ equipment.
- REFCOM-registered engineers: the same team does every visit.
- A plan that fits: one, two or four visits a year, with priority booking on larger contracts.
