Building HVAC Science

“I’ve been struck again and again 

by how important measurement is to improving the human condition.”

Bill Gates

Lend us your ears as Kaleb and Bill have a very fun interview with Ben Reed, VP of Products at TZOA, a relative new comer to the world of measurement products.


TZOA’s approach with the Haven product is totally unique: a retrofittable residential air quality monitor that lives inside the central air handler and can control 1 or 2 systems that can impact air quality.


Not just measurements/sensors, but control/solutions.


This product is exclusively available to qualified contractors and is NOT a DIY device.


In addition to a great streamlined product, the dashboard is AMAZING, largely due to the tight ties between the contractor-beta testers and clever product developers.
