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.
