Goodhue County HFH passes duct tightness test!
In order to access Impact Fund grant money, a house has to pass duct tightness testing, often more strict than Minnesota Building Code. This has been challenging, as HVAC Contractors are unfamiliar with the requirement. Often a home will not pass the first time, resulting in more time and resources spent on getting the system compliant. The Goodhue County affiliate asked their contractor, Ziemer Heating and Cooling, to get the system up to par. And that they did! Congrats to both Goodhue and Ziemer.
