Cold air returns, a critical link in your HVAC system
Cold air returns are a necessary portion of any HVAC system. Once warm air emanating from a supply register has depleted it's heat and has subsequently cooled down, then it returns to the furnace through the cold air returns. It is very important for cold air returns not to be blocked, as this will cause a reduction in air flow to the furnace. In extreme cases this will result furnace damage. So cold air returns perform an important function. But cold air returns are also important from an aesthetic standpoint. They are usually larger than a supply register and so cold air returns will seem very prominent in a room. Therefore it is important that the cold air returns not appear unattractive. This site offers a very wide variety of cold air returns that not only look very good, but also provide good airflow characteristics for the most efficient functioning of your HVAC system.
