Buildings in Qatar should run HVAC and chilled-water plant on a planned preventive maintenance schedule: monthly inspections of key plant, quarterly deeper servicing, and far more frequent filter checks in dusty conditions.
Why preventive beats reactive
Reacting after a chiller trips on the hottest day of the year is the most expensive way to run a building. Planned Preventive Maintenance (PPM) catches the small issues — a fouled coil, a slipping belt, a clogged filter — before they cascade into a failure.
The seasonal checklist
- Filters: inspect monthly; replace far more often in dusty seasons.
- Coils & condensers: clean quarterly to maintain heat rejection.
- Chilled-water plant: check flow rate, temperature and pressure on both primary and secondary sides.
- Pumps, belts & motors: check tension, alignment and vibration.
- Controls & setpoints: verify thermostats and scheduling against actual occupancy.
- Drainage: clear condensate trays and lines before peak load.
The payoff
A well-run PPM regime lowers energy consumption, extends equipment life, and keeps tenants comfortable through the summer. It is the single highest-return discipline in Qatar facilities management — and a core part of how Makan manages assets.
