Fresh air intake, new homes, and we all need to breath fresh air. Leavenworth Home Inspections
Most people just do not think about it. You buy a new home and think it should not have many problems, you hope!
Now the issue is that you as a home buyer most likely do not know what is required for new construction. Codes and the requirements that come with them are constantly changing, typically every three years. I try to keep abreast of these changes because I do quite few new home inspections and perform quality control/phase inspections for several clients.
On a recent new construction inspection I found the home did not have a fresh air duct or other approved means to bring in fresh air into the home. Since 1991 Washington State has required that whole house ventilation since newer homes are built much tighter that they older counterparts to meet the energy code requirements and to create a healthy indoor air environment.
Here in the Wenatchee and Chelan County area we typically use the Furnace/AC air handler to introduce the fresh air into the home using the home’s ductwork to distribute the fresh air to all the rooms.

Now there are other ways to meet this requirement but using the air handler is the most common method and usually one of the easier ways to provide fresh air throughout the home.
So I recommended that a fresh air is provided to the home as required. I suggested using the air handler with a fresh air duct and damper may the easiest solution to achieve this requirement.
On the re-inspection, I found that did install a fresh air duct as I recommended. But…. the duct never made to the exterior and is now pulling air from the attic! Obviously, this does not meet the requirement and will need to be corrected. There were a few other issues with this installation but the main concern was getting that fresh air duct to the exterior.

I often tell potential home buyers that having a new home inspection is a very wise thing to do. We all make mistakes but it is best to find some of these items at this time versus when selling the home when it will be out your pocket versus the builders.
