The Dangers Of Negative House Pressure

If you own a fireplace, it is important to be aware of the harsh side effects that negative air pressure can cause in a home. It is an issue that should be addressed as soon as possible in order to keep your house running efficiently and your family in good health. If you are worried that there is a negative pressure problem within your house, call a certified chimney professional today so that a resolution can be found.


There are many signs that may indicate your home is experiencing issues with negative pressure. Check out some of these below.

  • Unexplained Illness: If friends and family always seem to leave your home complaining of feeling ill, then air flow issues may be the culprit behind this occurrence. Take note as to whether or not these symptoms fade when people go back outside. If this is the case, call in a chimney sweep as soon as possible to ensure that your family stays safe and healthy.
  • Backdraft: Does smoke fill the room anytime you try to light a fire? This means that the air is not escaping properly and that venting issues are occurring. An expert will be able to look at the various causes as to why this may be happening. If everything with the structure of the chimney checks out, then it is likely negative air pressure causing problems within the home.
  • Mold And Mildew: Mold and mildew accumulation is another sign of pressure issues. It accumulates when a house is not given the opportunity to ventilate fresh air throughout it. When air sits, it becomes stale and heavy, causing condensation to occur and creating the perfect environment for mold to form.
  • Stagnant Odor: When air cannot ventilate like it is supposed to it simply sits, which means all of the odors throughout a home sit with it. Clean air needs to flow regularly in order to maintain a fresh atmosphere. Smells from cooking, laundry, pets, and the other various odors that accompany a busy family will not be given a chance to escape if the airflow is not circulating properly.


The best thing you can do if you suspect an issue with negative pressure inside of your home is call in a professional to check things out. Someone who is trained and certified will know exactly where to look and what to inspect in order to find the culprit behind your air flow issues. They can also guide you to various answers to the problem, so that you can find the best solution for your unique situation.
