My husband and I recently had a high-efficiency furnace installed in our home and are having issues with the cold-air return
In a conventional furnace, air from rooms in the house enters the furnace via the cold-air return
Here's a tip: Increase heat efficiency of woodstoves by creating a cold-air return
duct from the coldest room of the home.
The furnace fan draws air from the home's cold-air returns
and blows that air over the warm coil and then sends the warmed air throughout the house.
Avoid blocking radiators, heat registers and cold-air returns
There are two kinds of heating/air conditioning lines: delivery ducts and cold-air returns
, which carry cool air back to the furnace.
