How Do You Know Your Air Exchanger Is Working?
Friday we dipped into the house fund and had an air exhanger installed. We built our house in 1999 right before the new building codes in Minnesota kicked in requiring an air exchange among many other things. These requirements would add about $10,000 to the cost of a new home in Minnesota. Over the years we never noticed the lack of an air exchanger until we had our house resided in 2006. Being that Sela Minnesota had to follow the new codes they wrapped our house with Tyvek house wrap. This sealed the house up well but almost too well trapping the indoor air in the house. So now we are installing an air exchanger
to get fresh air in and bad indoor air out. So how do you know it's working? That's a good question. The only thing I noticed is that I seem to sleep better, not sure if that's the fresh air or just that I know an air exchanger is now in the house so it's keeping good air in that the house wrap sealed in.
