The majority of HVAC professionals talk about the temperature side of our business. This is common because keeping cool or staying warm is the customer’s main concern. Indoor air quality is just as important, or even more important, and ventilation plays a major role.

Still Air is Unhealthy Air

Even if your home is spotless, there are still billions of other organisms sharing your home. Bacteria, Viruses, mold, spores, and many other pathogens are hanging out on your walls, appliances, furniture, and even you!

There are many other contaminants that also reside in your home. Many of the products we use day to day like hair spray, nail polish, and toiletries linger in the air even after the smell has passed.

All of the airborne particles previously mentioned need to be removed from your home on a regular basis. It is recommended by the American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRE) that the air within the interior of your home be completely changed every four hours.


There are many ways to keep your home properly ventilated. When the weather is comfortable, open your doors and windows. Fans can be used to help bring fresh air into your home, or stale air out.

When it is too hot or cold to keep the windows open, your HVAC unit will do the trick. Be sure to check your air filters regularly. If your air filters are dirty, air will not properly circulate. This could ultimately reduce the amount of ventilation throughout your home.
