Controlling Moisture Buildup in HVAC Systems – An Important Step in Mold Cleanup Process in West Milford, NJ

October 5th, 2016 · No Comments

Water damage, leaks, moisture buildup, and condensation are some of the problems which can lead to mold problems in your home in West Milford, NJ, or anywhere in northern New Jersey. When faced with an infestation of mold, it’s best to hire a firm to perform mold cleanup as well as fix the underlying problem, otherwise the mold problem will resurface.

Your HVAC system can contribute to moisture buildup in your home, which in turn can cause mold growth. In the following sections we’ll look at some of the common problems found in HVAC systems that can contribute to mold and how those problems can be solved.

Problems in HVAC Systems Resulting in Moisture Buildup and Mold Growth


  • Moisture problems, and the resulting mold growth, in your home can be due to the way the HVAC system and its components are installed and function. Some common problems include:
  • Inadequate Dehumidification: If the HVAC system is not able to adequately dehumidify, it can increase the dew point inside the house, resulting in condensation and mold growth
  • Leaks: Leaks in return air plenums, exhaust air duct connections, and similar other parts result in the development of suction within building cavities. This can pull humid outside air into the building which then condenses over cool surfaces and facilitates a mold problem
  • Ineffective Drainage: Uncollected and undrained condensate collecting inside an HVAC system can result in drips, water leaks, and consequent moisture and water damage as well as mold problems


Maintain Low Dew Point: Your aim should be to maintain a low dew point, ideally, under 55OF in humid weather conditions, to reduce the chances of condensation over cool surfaces as well as lower the risk of organic materials absorbing moisture

  • Proper Sealing of Duct Connections: Each and every duct connection should be properly sealed to ensure humid outside air does not get into your home. Sealed duct connections will also stop condensation resulting from supply air that escapes into any unconditioned space
  • Prevent Condensate Overflow: Overflow of condensate (forming on cooling coils) from drain pans should be prevented, as well as condensation on the external surfaces of ducts, valves, diffusers, cold pipes, and air handling cabinets
  • Control Indoor Humidity: Indoor humidity loads should be controlled by utilizing proper exhaust ventilation from kitchen, shower, tubs, and other major moisture sources. Exhaust air needs to be balanced using dry air to prevent the exhaust system from drawing unconditioned outside air into the building
