Basement in Florida? Why Mold Took 20 Years to Fail this House...

Corbett Lunsford

A very cool client of ours named Niko came to us with a wildly different home issue- a finished basement. In Florida. That's vented to the outdoors. Watch us tour the home being renovated with Tony Gomes, my Tampa go-to-guy for advanced diagnostics on existing homes. We explore how it's possible that mold was held at bay for 20 years, until Niko did a 'good' thing and replaced an old HVAC system with a VRF (variable capacity) heat pump.

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

Corbett Lunsford

Another installment in a series with Healthy Indoors Magazine (http://HealthyIndoors.com) follows the real-life, gritty planning and installation of the make up 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.
