AC Maintenance After the Summer Season: A Checklist for Facility Managers

In Qatar, air conditioning is not a luxury but a core building system. A failure in July or August means disrupted work or classes and immediate complaints. After the long summer months units have run at full load, so autumn and winter are the best time to inspect, service and prepare them for the next season without pressure.

Core checklist

• Clean or replace filters in all indoor units.
• Wash condenser and evaporator coils to remove dust.
• Check refrigerant pressure and confirm there are no leaks.
• Clear condensate drain lines to prevent water damage to ceilings.
• Measure compressor and fan current and tighten connections.
• Test and calibrate thermostats and controls.
• Check insulation on pipes and ductwork.

Warning signs that need immediate attention

• Air not cool enough despite long run times.
• Unusual noise or vibration in the outdoor unit.
• Ice forming on pipes or coils.
• Water stains or leaks around indoor units.
• A sudden rise in the electricity bill.

The impact on energy use

Dirty filters and dusty coils force compressors to run longer, increasing electricity use and shortening unit life. A simple preventive schedule pays off for both the budget and user comfort.
