When the air inside a building is under negative  pressure relative to the outside air, many indoor environmental problems  can develop or worsen, especially in a hot/humid climate. Affected  areas can range from localized areas of building cavities (in exterior  walls or ceilings) to excessive humidity throughout the building  affecting all materials and occupants. Excessive negative pressure is  often related to HVAC system design, installation or maintenance  problems. Indoor Environmental Technologies' specialized equipment and  experience allow us to locate the source of building pressure issues and  develop recommendations for correcting them. 

  In a hot/humid climate, like that of Florida, it is  critical that your HVAC system properly controls humidity and  temperature. Excessive humidity can lead to mold growth, deterioration  of building materials, contamination of personal contents and many other  Indoor Air Quality concerns. HVAC system problems can be related to over-sizing of the  system, leakage or poor design of duct systems, inadequate maintenance,  excessive humidity in attics or crawlspaces,  etc. Indoor Environmental Technologies  work with HVAC engineers and  contractors to solve HVAC concerns, as well as to correct any building  issues that may have developed. 

  To spot trends that are useful in diagnosing  building problems, Indoor Environmental Technologies has developed  methods of monitoring building humidity and material moisture content.  This moisture monitoring can be accomplished over a two to four-week  period or on a permanent basis. Permanent monitoring allows those  responsible for building maintenance to be notified immediately and  automatically by email when moisture problems begin to develop in a  specific location— before they cause serious problems. This type of early warning system has proven capable of saving tens of thousands of dollars.
