How to Reduce Duct Moisture11/28/2015 Back To Blog
Moisture is an enemy because it encourages the mold growth. When mold is built up inside air ducts, the air transferred into our homes is contaminated. Contaminated air might be the reason for many allergies and respiratory problems and this is what we often refer to as a sick home. Such serious health issues should be everyone's concern and the reason why air duct cleaning and inspection must never avoided. As Air Duct Cleaning in Simi Valley explains, if ducts and the cooling coils of the HVAC system are checked once a year, condensation can be controlled. What is condensation? It's actually humidity. The term is the exact opposite of evaporation. It's when water vapor turns to liquid. This happens when the duct temperature is lower than that of the surrounding environment.
With air ducts installed in places, which are not ventilated (like attics and basements), chances are that there will be a problem. Non-ventilated spaces have higher temperatures and, thus, humidity. When cool air is transferred through the ducts, water vapor in the room will turn to water and if the humidity continues to be high, you will have a mold problem. Since mold grows on dead cells and other contaminants contained in debris and allergens transferred with air by outside, the problem will only get worse.
Prevent moisture accumulation in the ducts
The best solution is air duct seal repair and proper insulation of the ducts. It will certainly help if the attics and basements in which the unit is mostly stored at could be ventilated. It's also necessary to keep humidity levels inside the house under 55%. This means that you must be extra careful and use the exhaust fans both in the kitchen and bathroom to keep the humidity levels down. The ducts should be well insulated, too. It's no wonder why air duct replacement is recommended when the ducts are really old. At older times, they were hardly insulated. If yours is not insulated or the insulation material is partially damaged, you can install a new one. It's easier to get self-adhesive r-6 value insulation materials. If it's not self-adhesive, install it around the duct and put a tape all around so that it will stay in place.
Though, these are not always the best solutions. If your ducts are old, non-insulated and cracked, you can temporarily solve the problems with air duct repair solutions but it will be best to schedule the replacement of the ducts eventually. They must be well-sealed and materials nowadays are much better than they used to be. If this is not in your budget just yet, just make sure all cracks are sealed and the ducts are insulated. You must also make sure the condensate pan of the system works okay. If doesn't drain properly, you might consider replacing it. If you can't replace the ducts, at least replace the air duct filters. This is of the essence, too.
