Importance of Cold Air Return’s Location

Every building that uses forced hot air for heating will have cold air return vents. They do precisely what the name implies: return cold air from registers to the furnace so that it will run properly. Return vents also provide air circulation. Return vents are necessary to prevent pressure buildup that may lead to illness, help prevent mold and mildew, and help prevent deterioration of the building structure. When warm air is forced into a room it replaces the cooler air. The cooler air must be pushed out of the room otherwise it becomes over-pressured. The cooler air is forced into the return vent back to the furnace where it is reheated, and the cycle begins again.

Examine your home heating system. It is important to understand the space that you’re heating. The output of air must equal the input of air. If the input into the furnace is less than the output, this will cause pressure in the house and a possible backup of dangerous fumes. If the return vents are lacking in proper spacing, the air will travel to the furnace through rooms and down stairways. This creates a draft which defeats the purpose of a forced air system.

Place your cold air return vents on the inside walls of buildings at the lowest point. The return vent pulls cold air from the bottom of the room and returns it to the furnace to be reheated and returned as warm air.Unlike supply vents, return vents do not need to be cased in metal. They can be placed into staircase cavities, stacked closets that run one on top of the other, or in stud cavities in the wall. Where one return vent serves an entire zone, air space should be provided under doors so that when they are closed the registers can still draw air without pulling against the furnace (which causes negative pressure in the home).

Place the vent at least 10 feet away from a thermostat, because the cold air draft may cause incorrect temperature readings.

Use exhaust fans to expel the air from kitchens and bathrooms because of the high moisture content. Follow municipal building codes regarding vents in these rooms.

How to Cover Cold Air Returns

Cold air returns are vents in your home that pull cold air into the heating/air conditioning system. The air temperature is then regulated and pushed back into your home through the vents. Using a cover on your cold air return serves many purposes, including adding a touch of home design as well as facilitating good ventilation to the heating or air conditioning unit without leaving a large hole in your wall, ceiling, or floor.

First, you have to wipe out the cold air return itself. This will help remove some of the harmful dust and germs that may be lingering at the front of your air return.

Then wipe out around the cold air return. Returns that are not covered can get messy, especially if you have children or if the return is on the floor. It is important to clean the area before applying a cover to avoid the bacteria that may begin to grow there.

Remember to unwrap any packaging from the return cover. Sometimes they can be completely wrapped in plastic, and other times they may just have a piece of paper or cardboard wrapped around them. Discard the packaging.

Place the cover over the return and push on the sides until it pops into place. Sometimes the return cover will have small holes meant for screws or nails. If your model has these, screw or nail the cover in place. It is a easy task.

There are many louvered design cold air returns at the floor register store, which is made of hardwood. All the vents are unfinished, so it is a great choice, especially for some home design. It allows to be stained as possible.

Maintaining of Air Return Vents

After you have installed your cold air return vents, it’s easy to forget about them and just get on with life. STOP! In order for your rooms to continue breathing freely with the ventilation that has been achieved by fitting these cold air return vents, you will need to mark a little regular maintenance into your calendar. Don’t worry, upkeep is a quick and simple procedure but important nonetheless. If there’s not enough outdoor air entering a home, pollutants can sometimes accumulate to levels that can pose health and comfort problems indoors, so you can see the importance of keeping the apertures and ventilation grilles clear so that they can breathe freely.

You’ll be peased to know that this is not a difficult job. Unscrew the air vent from the wall and wipe over with a damp rag until clean. (You might want to use a toothbrush to get in between the slats) Finally, vacuum the duct behind the air vent to finish the job and reattach the parts. That’s it, the cold air return vent is clean now.

Tips of Cold Air Return Vents

The typical ventilation cycle in a home starts with air entering the cold air return. A fan on the furnace sucks the air into the furnace, drawing it through a filter. The air passes through a heat chamber where it gets warm. The warmth is created either by combustion due to natural gas or propane ignition or electrical conduction. The air flows through the chamber and is pushed to the vent pipes by a blower fan.

Cold air return boxes are typically located near the center of a house. Older homes (pre-1960 construction) typically have one large return on each floor. Homes built in the 1960s, 70s and 80s often have a cold air return in each room. With the advent of high-efficiency, high-capacity furnaces in the 1990s, homes needed fewer returns. The number of returns are not dependent on the number of HVAC (heating, ventilation, air conditioning) air vents.

Because cold air returns draw air in to the furnace, there is slight suction. The force often picks up air particles and draws them into the HVAC system. On a clean vent, dust and other particles go straight to the in-line furnace filter. As time passes, dust collects at the vent, caking up around the entry and choking off the air intake. This causes the furnace to work harder to pull in more air. Simple dusting on a regular basis can keep a furnace working properly.
