"It’s not the heat, it’s the humidity"
 Nowhere is that more true
than in the Lowcountry. High humidity within your
home or light commercial building is not only uncomfortable; it is the
primary condition leading to mold and overall poor indoor air quality.
Unfortunately, most residential and light commercial HVAC systems (air
conditioners) are designed to maintain temperature, not humidity. In
many parts of the country, systems designed to operate based on temperature
alone work fine; in the Lowcountry, many do not.
There are a host of conditions that contribute to elevated humidity levels
including infiltration, poor/inadequate HVAC design, site conditions and
moisture-laden crawl spaces. For absentee owners,
interior humidity can be particularly problematic if air conditioning
systems are "set back" for extended periods.
If high humidity is a
problem in your home or business, Air Plus can
help by providing you with a professional evaluation to determine sources of
moisture and develop a strategy to maintain acceptable interior humidity
levels. If corrective measures are required,
Air Plus is available to install necessary systems and
equipment, providing you with a turnkey humidity control solution.

Home owners/buyers
should be aware that humidity control (or moisture removal) is only a
secondary benefit of standard air conditioning (i.e. moisture is only
removed when the thermostat is calling for cooling). Although currently
accepted HVAC load estimating methodologies attempt to maximize the
moisture removal capabilities of standard air conditioning, it does on
ensure satisfactory results,
particularly in warm humid climates. Humidity control can be improved with
controls, the use of variable speed air handlers and the use of
multi-stage compressor systems. Additionally, whole-house dehumidification
systems can be installed to precisely control humidity independent of the
air conditioning system. Those with mold allergies, asthma or other
respiratory concerns should be particularly aware of the benefits of
interior humidity control.

PICTURES
FROM THE FIELD |
|
Location:
Leader Lane, Hidden Cove, Mt. Pleasant
|
 |
 |
|
High
humidity and poor HVAC design resulted in mold on the ceiling and cabinets
in this Mt. Pleasant home.
|
Location:
Commercial Building, Kiawah Island
|
 |
High
humidity coupled with cold interior temperatures resulted in substantial
mold growth behind the wallpaper in this meeting room on Kiawah Island.
|
Location:
South of
Broad, Charleston
|
 |
Uncontrolled humidity in this South of Broad home was causing the paint to
literally fall from the walls. Mold was also a problem as the
humidity levels were routinely in excess of 70%
