A quarterly preventive maintenance checklist for office facility managers and HVAC technicians maintaining the heating, ventilation, and air conditioning systems that keep office environments comfortable and productive. Covers filter inspection and replacement, thermostat calibration, ductwork condition, condensate drain clearance, refrigerant level checks, and the seasonal changeover tasks between heating and cooling modes.

HVAC is typically the largest energy cost and the most common source of comfort complaints in offices. A dirty filter reduces airflow and increases energy use by up to 15%. A clogged condensate drain causes water damage. Regular maintenance keeps the system efficient, prevents breakdowns, and maintains the indoor air quality that affects employee health and productivity.
