How to Design and Install Kitchen Exhaust and Make Up Air Ventilation (Case Study)

Another installment in a series with Healthy Indoors Magazine follows the real-life, gritty planning and installation of the makeup air system in a 1950’s ranch over a crawlspace. The goal here is to install effective ventilation for the kitchen range with an exhaust hood AND make up air that will hopefully be the path of least resistance.

We’re using a Broan exhaust hood paired with an Aprilaire KV make up air damper, or an 8144NC (in an experimental application, as explained in the video). This house is not airtight by any means, and some might think make up air is overkill in an older home, but obviously we disagree enough to suffer through this.
