Your indoor air quality is likely not to bother you during the summer since your house is usually well ventilated. However, the indoor air quality can begin to decrease as the temperatures start to drop. This can be very stressful, especially if you don't know what's causing your indoor air quality to suffer. Maybe, your AC is not functioning normally, and that's the reason why you have poor air quality in your home. Therefore, you might want to consider hiring a specialist in heating and cooling services to inspect your system. But, it is important to understand some of the reasons why your indoor air quality might suffer during the winter. 

1. Poor Ventilation

Although it might be freezing cold outside, always try to open the windows occasionally when the weather permits. Opening the windows allows fresh air to get, and this improves the air quality in your home. However, failing to open the windows means that your house will be poorly ventilated, and it will not be receiving the much-needed fresh air. Lack of fresh air in the house means that the air quality in the house will be affected during the winter.

2. Failing To Clean the Ducts

Failure to clean the ducts in your house can significantly affect the indoor air quality — especially during the winter. Mostly, the ducts in your home are filled with dust particles as well as other debris that are filtered into your home. This means the dust particles will end up finding their way into your house and this can reduce the air quality in your house. Therefore, it is important to ensure that the ducts are cleaned just before the winter starts to avoid this problem.

3. Failing To Change the Air Filter in Your Furnace

Air filters help in keeping the interior air fresh during the winter. You don't need to open the windows in your house if you have good filters since they prevent your indoor air from becoming stuffy. However, failing to clean or change the air filters can make the indoor air quality to suffer, especially if the filters are clogged with dirt deposits.

4. Un-Serviced Furnace

Many people don't like servicing their furnaces, especially if they seem to be functioning well. However, failure to order routine maintenances can affect how the system functions, which can, in turn, affect the quality of the indoor air quality. Your system naturally collects debris and dust over time, and if this not cleaned, it can end up contaminating your indoor air. Routine maintenances can help to ensure that the system is functioning normally, that the system won't affect the indoor air quality during the winter.

5. Mold

Lack of proper ventilation in your house creates the perfect grounds for mold to breed. While mold plays an important role in breaking down substances like organic matter, it is not good when growing in your house since it affects the quality of your indoor air.
