How to Improve Indoor Air Quality in a Windowless Room

It can be easy to tell when the air inside your home is of poor quality. Poor indoor air usually feels stale or has an unpleasant, moldy odor that’s often more noticeable upon entering a room. Typically, in such cases, your first instinct is to open a window. This is certainly an effective solution most of the time. But what if there is no window at all in the room or the space simply has poor ventilation?

JC Refrigeration Heating and Air Conditioning shares some tips to help you improve indoor air quality in poorly ventilated or windowless rooms.

Duct Cleaning

Schedule professional duct cleaning services at least once every three years so that you can keep your ventilation system in good condition. This is also important in preventing dirt buildup in the air ducts. When the air ducts are clogged with too much dirt, this can cause your indoor air to become stale and contaminated.

Air Purification System

Consider installing a whole-home air purification system so that indoor air pollutants can be actively removed throughout your home. There are different types of air purifiers on the market today, so make sure to consult experts regarding the type of air purification system that best suits your needs.


Excessively high humidity inside your home can be bad for your health because this usually spurs the growth of allergens like mold and dust mites. That said, you might want to consider investing in a dehumidifier if your indoor humidity level is higher than 60%. You can have your home assessed by a professional so that you can confirm humidity issues in your home.

Extractor and Exhaust Fans

If your kitchen has limited space and there is no way you can install a window in this area, you can opt to have a large extractor fan instead. An extractor fan can easily remove all the moisture and steam that normally build up in the kitchen when food is being cooked. You can also install exhaust fans, which can get rid of the smells inside your kitchen and refresh the indoor air.
