My Furnace is running very loud but it is not heating or not heating very well.
It sounds to us like this is due to a dirty air filter. Turn the furnace off and then slide out your Air Filter (usually right next to your furnace) and take a look at it. If it is dirty please replace it. It is important you replace your filter on a regular schedule as dirty filters starve the furnace and burn out motors, costing you a lot of extra money down the road. Set calendar reminders.
If the filter is fine, make sure you have all the return registers around the house opened up and that furniture isn't blocking it.
