Your house needs to have a [comprehensive ventilation strategy](https://bc.rodenhiser.com/rodenhiser-blog/natural-home-ventilation-strategies.html) in order to improve the air quality, prevent back drafts of combustion devices and reduce humidity to prevent mold growth. [![comprehensive ventilation strategy, Holliston, Massachusetts](https://bc.rodenhiser.com/wp-content/uploads/2013/05/indoor-air-quality.jpg)](https://bc.rodenhiser.com/wp-content/uploads/2013/05/indoor-air-quality.jpg) Take these three aspects into consideration to further enhance the effectiveness of your insulation: - **Improving indoor air quality -** To [optimize indoor air quality](https://bc.rodenhiser.com/rodenhiser-blog/optimizing-air-quality-boston-home-remodeling-building.html), it's crucial to employ mechanical ventilation. Random leaks or occasionally opening windows doesn't freshen up the house enough. Tightly sealed homes should arrange for the air to flow in from an outdoor location, where it's fresher. This arrangement rules out locations which don't have the best air quality, such as garages or rooftops. - **Mitigating the risk of back-drafts -** The next step is to notch up your ventilation strategy by identifying and fixing any hazardous issues occurring due to combustion appliances. Air flowing down the flue pipe doesn't allow for the effective exhaust of combustion gases. This can result in the gases and smoke being suspended in the living space, which in turn leads to an increase in [carbon monoxide](https://bc.rodenhiser.com/rodenhiser-blog/making-sure-your-carbon-monoxide-detectors-are-where-they-belong.html). The solution: Isolate the gadgets from the living area and provide them with their own combustion ducts. - **Reducing humidity and mold growth -** Owing to Massachusetts’ long and humid summer weather, it's crucial to address the problem of humidity before mold sets in. This issue can be easily solved by employing a robust ventilation system, sizing the cooling system and avoiding moisture-trapping material. A large air conditioner doesn't maintain long enough run times to dehumidify the air sufficiently, while a proper ventilation system is perfectly fit for the task.
