Why Do My Windows Collect Condensation?

Window condensation develops in varying conditions. However, the primary cause of moisture developing on windows is high moisture content or humidity within a home. An abundance of window condensation can cause damage to the surrounding area such as rotting a wood frame or wood windowsill. Ignoring window condensation for long periods of time can lead to dangerous mold growth in the immediate area that can become airborne and dangerous if it is not treated in time. Furthermore, the levels of indoor moisture or humidity needed to cause window condensation are levels that are considered unhealthy and should be remedied according to the root of the problem.

Causes Of Window Condensation

One of the sources contributing to window condensation could be an AC unit which is an integral part of any heating, ventilation, and air conditioning (HVAC) system. AC units have filters to collect any dust or small debris while air is circulating. When filters become clogged, airflow is hindered causing higher humidity. Air filters should be checked and changed on a regular basis to prevent excess moisture in the air. AC units that are oversized according to the size of a home will run what is known as short cycles. Short cycling occurs when the large AC unit cools an area too quickly in a repetitive manner throughout a day without the ability to properly reduce humidity leading to window condensation.

Here Are Some Tips On How To Improve Your AC Unit

Air is circulated throughout a home through ducts. Any type of obstruction or leak in the ductwork can hamper airflow leading to high moisture content or humidity. Finally, cooler air produced through an AC unit is dependent on refrigerant levels. Refrigerant that is over or under charged will cause a unit to be overworked and result in poor air quality and humidity. High indoor moisture levels believed to be caused by an AC unit can be addressed by a professional HVAC technician equipped with custom tools to test and rectify any problem.

During the winter season, window condensation is caused when significantly warmer, moisturized indoor air comes into contact with the much cooler surface of a window. The same reaction occurs in warmer climates when cooler air with excess moisture comes into contact with warm or hot window surfaces. Excessive window condensation can be remedied by replacing single pane windows with double pane windows or using exhaust fans to absorb extra moisture in the kitchen and bathrooms. However, more complex causes such as poor ventilation throughout a home or AC unit complications should be handled with professional assistance.
