If your heating and cooling ducts beneath your house are disconnected somewhere?
If your heating and cooling ducts are disconnected somewhere beneath your house how do you go about fixing that? Can you do it yourself? If yes..how? If you have to have it done professionally about how much does that cost? AND just how does that happen?

This is usually an easy DIY project. I guess it would depend on what type of heating system you have and how many vents you have in your home, obviously the more vents the more work. Myself, I’d have someone come in and do it.
It is an easy diy project. As far as fixing it, that depends on the type of duct system. Also, as long as you are repairing it, you may want to seal the ducts and insulate them to save money. For more info, check out the ducts page at my source.
