How Humid Climates Affect Indoor Air Quality

With summer coming into full swing, humidity is on the rise in New England. Our fellow professionals at Ductworks, Inc. in Colorado explain the impact that a humid climate has on indoor air quality.

Regional climate plays a large role in Indoor Air Quality and comfort. Regional climate characteristics are determined by geographic location and long term weather conditions. Two of the most important factors that affect an areas climate are temperature and precipitation.

What makes humid climates uncomfortable?

Humid climates have a high amount of water vapor in the air. When it's hot, high humidity makes people feel hotter because it reduces the ability to evaporate moisture from the skin. In humid climates, becoming comfortable means going into a conditioned space.

Potential for mold growth

While mold spores are in every region and every climate, mold growth is highly dependent on the amount of humidity. Mold growth typically occurs when an environment reaches a relative humidity of 60 percent or greater in a 72 hour span. If mold is found within your home or workplace remediate the problem immediately, mold spores can be distributed throughout the home or building through the HVAC system impacting indoor air quality.

Air conditioning in humid climates

Air conditioning coils serve a very important role in regulating temperature and humidity in humid climates. As air passes through the evaporative coil of the air conditioner, heat and moisture are removed from the air. To a degree, the lower the humidity level, the more comfortable you will feel at a given temperature.

Air duct cleaning and HVAC maintenance

Overtime foreign debris is drawn into the evaporative coils and fan blower of the air conditioning system, gradually decreasing air flow and energy efficiency. Maintaining HVAC system, will keep your cooling and heating components operation at peak energy efficiency, and prevent potential indoor air quality problems. Yearly air conditioner inspections and routine air duct cleaning with assure maximum efficiency.
