Good afternoon! I just wanted to share some information that isn't widely known.
Colorado has passed me laws for furnaces and water heaters. It's the low NOX laws. What this means is that some Colorado businesses that supply us with furnaces will no longer be able to sell 80 percent units. What this means is that new furnaces have to be 95 percent or higher efficiency rating.
If your old furnace is or has a metal flue then it's 80 percent. Now all furnaces will have to have plastic flues. In telling you this if you have a basement that's finished it's going to cost you more. They will need to tear up some ceilings to get the flue outside. Then of course fix the area that was torn up.
