Understanding why proper ventilation is essential to your home and health

Ventilation is typically not the first thing that comes to mind when homeowners consider ways to increase their home's comfort or the effectiveness of their HVAC-R system. However, proper ventilation is essential for the comfort and health of any house. Without adequate ventilation, your home may trap heat and moisture, which will make it uncomfortable. This might happen in your attic, crawl space, or basement.

The right ventilation makes a big difference

It's crucial to comprehend what is happening in your home before you begin making improvements to the ventilation and HVAC-R systems. Here are some crucial components of home ventilation:

  • Uncontrolled vs. controlled ventilation:

"Uncontrolled" refers to air that seeps into or out of the home. This occurs in any location where there are even the tiniest cracks in the exterior of the house, including around windows and doors, through inadequately insulated walls, and elsewhere. Uncontrolled ventilation makes it possible for the heated or cooled air that you have paid to condition to leave the building.

A house becomes less pleasant and more expensive to heat and cool due to this ongoing leak. Air sealing decreases uncontrolled ventilation in a home, yet "managed" ventilation is necessary for healthy indoor air.

  • Active ventilation vs. passive ventilation:

Electric vent fans are used to achieve "active" ventilation. Kitchens and bathrooms usually require active ventilation to remove air contaminated with smoke, smells, and wetness from cooking and bathing.

For this reason, small vent fans are installed in these spaces. Active ventilation can be provided in attic spaces using attic fans and powered attic ventilators (PAVs). However, if your home has not been properly air-sealed, this form of active ventilation may cause more harm than good.

Negative pressure in the attic, if it's too strong, can draw conditioned air from the rooms below. "Passive" ventilation is by definition, more energy efficient because it doesn't require electricity. With cooler air being taken in at the soffits and hotter air being expelled from Passive ventilation in the attic can be achieved by ridge and gable vents. In a In a similar manner, to mitigate summertime heat buildup, the living area below benefits from a cooler attic by staying cooler.

Key areas of the home for ventilation

It's critical that ventilation occurs in the appropriate places in order for a home to retain efficiency and comfort while having excellent indoor air quality. The following three areas need ventilation attention:


Your attic is the hottest room in the house in the summer because hot air rises naturally. However, the living area beneath the attic will be uncomfortable if this hot air cannot leave the house. Attic fans are a wise addition for many homes since they will encourage hot air to leave the building, which is crucial if your attic contains air conditioning system ducts.


Another ventilation choice for many homes is passive roof ventilation. The three primary kinds of roof vents are those on the soffit, ridge, and gable, and each one lets hot air leave the house so that it stays cooler within.

Crawl spaces:

Vents in the crawl space compromise the comfort, efficiency, and quality of the air in your house in contrast to those above. Vents in the crawl space let wet, humid air in, damaging insulation and encouraging the spread of mould.
