There may not be any snow on the ground yet, heck, there isn't even any cold air out there. But, that doesn't mean we're going to miss it all together. Winter is bound to show up in full force sooner or later.
When it does, hopefully you're prepared for it. The National Weather Service, along with other federal agencies have declared this whole week as "Winter Weather Awareness" Week.
One of the points they touch on this year is home safety. Hovlands Inc., in Eau Claire, suggest to get those furnaces checked before the freeze. One of the most common things to do is to change the air filter in your furnace.
Changing your filter will help prevent malfunctions in your heating unit, and, it'll save you a few bucks by having your furnace run more efficiently.
