A Quick Floor and Wall Registers Primer
You’re an interested homeowner that wants to stay connected with every aspect of the HVAC system in your home. You do this so you know you’ll be comfortable, no matter the weather, year round. Delivery of the cool or warm air that keeps your family happy is important and that’s where floor registers and cold air returns come into play. Knowing how and why these important parts work and what you can do to increase their efficiency is another part of looking after all aspects of home. These are an essential part of your heating and cooling system and as such you need to be sure first and foremost that none of them are covered or otherwise obstructed. Although draperies and other accessories are great for the atmosphere in your rooms, they aren’t doing a lot of good when they’re blocking registers on the floor or wall. Remember that the air needs to flow freely from the furnace or the air conditioner. Here’s how the whole thing works and why these are so important to the environment of your home. Many homes today are heated and cooled by the combination of the furnace, air conditioning unit and ductwork. At the business end are these registers that move air from where it originates at the furnace or air conditioner to various points around your home. Floor duct registers cover the air ducts in individual rooms. They protect people from injuring themselves on the actual ductwork and allow for a room by room air flow control through a series of levers. Wall registers, like the name implies, are fastened to the wall with screws but do the same job as their counterparts on the floor. A cold-air return is a vent which sucks cold air into a furnace so that it can be heated and brought back to a room through a furnace register. Depending on the design, each room in a house may have a cold-air return, or returns may be strategically located at various points around the house. The benefit of these returns is air drawn from a room is naturally closer to the desired temperature, which means less energy is required to heat or cool it to the necessary level. Typically, a cold-air return is located near the floor; because heat rises, the coldest air will be close to the floor. Locating a vent up high would leave pockets of cool air near the floor, which would be undesirable when the goal is to heat a room. Registers which emit hot air can be located at various heights, depending on the design of the system. Often, the interface of a register and that of a cold-air return look identical. People can tell which is which by waiting for the furnace to turn on, and holding a piece of tissue in front of the vents. If the tissue is pushed out, the vent is a register, and if it is pulled towards the vents, it is a cold-air return. Both returns and registers typically have filters which prevent the passage of dust and dirt, and these filters need to the periodically changed to avoid clogging the vent.
