Ventilation Problems? How to Determine and Solve

Published on: April 25, 2012

Every house needs to breathe. It is not a living organism, but it does need to have air flow in and out for it to remain healthy for the occupants. During your next air conditioning service and repair visit, evaluate your house’s ventilation.

If your house has a problem with recurring mold growth, you may have a ventilation problem. Begin by noting where the growth is occurring or recurring. Locate any nearby water pipes and repair any leaks immediately. Mold growth on the ceiling could indicate leading or condensing water pipes. It could also result from moisture from leaking or uninsulated air ducts. This needs attention from an air conditioning service and repair company.


The air conditioner removes moisture by dehumidifying the air. If no water leaks are found on inspection and the ducting system is intact, there may be a problem with ventilation. Airflow through the attic is essential. Adding soffit vents allows the air to flow into the attic. The air must have an exit. Air turbines, ridge vents or attic vents pull the air though the attic and send it outside; resulting in moisture being released and preventing inside mold growth. The vents can be added during an air conditioning service and repair visit.

Ventilation for the inside of the house is provided through the HVAC system. Air is pulled from the inside of the house, heated or cooled, and then returned to the inside of the house. Outside air comes in when the door or windows are opened. The hood vent over the stove, bathroom vent and attached garage all allow outside air to come in. Ensure proper ventilation for the house during your next air conditioning service and repair date.


Proper ventilation for your home is not hard to achieve; maintaining your HVAC system is the best way. In humid climates, it is essential.
