For all you Idaho, WA and MT HVAC Co. Here in Oregon we are going to energy star 3.0 in 2013. I know that the previous mentioned states went 3.0 in 2012.
My question is how was the transition? How many hours is 3.0 adding to a new construction home? Are you having to add balancing dampers to all the ducts to meet the +- 20% room cfm requirement? Our company is ready and approved for the change just would like some experienced feed back. Thank you in advance.
