I'm talking about office buildings at least 10 stories tall or taller.How often is building maintenance supposed to change air filters in a large building?
Depends on the building use and the operating Theater.
For instance, a building in Texas would require a shorter preventive maintenance interval than a equally sized and used building in New England.
The building comes with all the paperwork for recommended preventative maintenance. You could ask to see the recommendations and the maintenance records if you are the renter.
