Tips From Common Practice
- Change filters on a schedule set by your dust load, often every 1–3 months.
- Keep a list of every unit with its model, serial number and age.
- Compare repair quotes against the unit's age before replacing it.
How Often to Schedule
Facilities usually schedule HVAC contractors at least twice a year, before cooling and heating seasons. Your lease, insurer, local code and equipment manuals can require more, so check them first and add the dates to your preventive maintenance schedule.
