How can we find out why our office is so humid?

You must check your HVAC system because it may be the reason why the office or building is too humid. Sometimes humidity may result from problems with air quality system.

• Is the HVAC system well-maintained? Clean dirty coils, which reduce cooling and dehumidification. Clogged pans may hold standing water. Leaks in the mechanical system let moisture enter the building.
• Is the indoor air quality system being operated properly? Make sure the cooling fans run at a moderate speed. Sometimes air velocity is set too high, because spaces are not adequately cooled. But the result can be higher humidity levels in a building.
