Ventilation is the exchange of indoor air with outdoor air, and it is responsible for removing indoor pollutants and for controlling moisture within your home. When you want to make your heating and air conditioning system more efficient, or improve the air quality within your home, it is an important element to consider. There are several different ways that air is exchanged within your home.

Natural ventilation is the most commonly used method. It occurs when air moves through small cracks or holes in the home or when you open windows and doors to let more air in. This method is uncontrollable because it relies on outdoor conditions, and a home that was built for energy efficiency will have the holes and cracks that allow air to pass through.

Spot ventilation improves the effectiveness of other home venting systems. It removes pollutants and controls moisture at their source. This method utilizes exhaust fans in areas such as the kitchen or bathroom when there are high amounts of moisture in that area.

Whole-house ventilation systems use a network of ducts and/or fans to pull stale air out of the house and bring fresh air inside. This type of system is generally installed when you’re concerned that the other methods aren’t doing enough for the air quality in your home.

If you’re concerned about the air quality in your home and aren’t sure of your best option, you should consider hiring a professional contractor to check out your heating and air conditioning system.
