If you’re considering your options for a whole house ventilation system, you came to the right place. In this post, we’ll tell you about the types of whole house ventilation systems and explain what is involved with each choice.

The types of whole house ventilation systems available to you will likely differ depending on if you’re trying to retrofit an old house or you’re installing the system in a new house. This is because of the way new homes are built tightly for high performance. Mechanical ventilation systems are more difficult and expensive to retrofit to old houses.

Supply-only, exhaust-only and balanced ventilation systems are your options for whole house ventilation systems in modern homes. For older homes, your options consist of local exhaust, natural ventilation, and dehumidifiers & humidifiers.

Continue reading to learn more about these various types of whole house ventilation systems so you can decide which is right for your home.

Whole House Ventilation Systems for New Homes

Supply-Only

Supply-only is a type of whole house ventilation system that involves a fan drawing clean outside air into the home. The system can filter the air and minimize the amount of humidity it draws in.

In contrast to exhaust-only, this method will pressurize the house. It’s a great option for those who are concerned with the quality of air entering their home.

Exhaust-Only

Exhaust-only is a whole house ventilation system that involves localized fans (such as in bathrooms and kitchens). The fans will draw air out to depressurize the home. Then, air will infiltrate through any cracks in the home.

This type of system works best in locations where there isn’t too much consistent humidity in the summertime, such as there is in the South.

The last thing you want to do is invite too much moisture into your house because it can cause damage to your interior. The other consideration here is that you risk pulling air in from an unknown supply.

Balanced

A balanced ventilation system will balance the amount of indoor air that is exhausted with the amount of outdoor air that is supplied into the house. This maintains a fairly consistent pressure within the home.

This is not the most affordable option because it will involve technology that improves efficiency and pressure balance. This technology can consume a significant amount of electricity which will affect your energy bills.

Whole House Ventilation Systems for Old Homes

Local Exhaust

Local exhaust is one of the options available to you as a whole house ventilation system if you have an old home. Local exhaust fans need to be used in moderation in hot and humid climates since you run the risk of too much moisture entering your walls and causing damage.

However, if you combine local exhaust with opening the windows, this should help create a nice balance in your home without causing moisture damage over time.

Natural Ventilation

While this may seem obvious, if there is not a huge problem with the air in your home, you might want to consider natural ventilation as a whole house ventilation system. This is affordable and will allow air to flow nicely throughout your house.

You can combine this natural system with a whole house fan if you don’t have much wind in your area. The best time to open your windows is at night when the air is cooler. You also want to aim to have dry air entering your home as much as possible.

Dehumidifiers & Humidifiers

When you live in a hot and humid client, sometimes air conditioning won’t be enough to cool your home because you’ll still feel some amount of moisture in the air. In this case, you can install a dehumidifier for your entire home.

In the winter in dry climates, your heating can cause your home to lack enough moisture in the air to be comfortable. This is where a humidifier will come into play.
