You should never block your air return vents. Period. However, if you're looking to keep your home cooler in the summer, you can try closing lower supply vents and keeping upper ones open, allowing cooler air temperatures to come in from above and sink throughout your house.
Conversely, in the Winter heating season, you will want to pull the coldest air back to the furnace to be warmed and create circulation. In these months, you'll want the lower air return open and the upper air return closed.
In warmer months, do the opposite — open the supply vents in higher locations and close the ones placed lower. This will direct more cold air to the ceiling, which will sink to cool the whole space.
Even Air Distribution: Two vents help distribute air more evenly throughout the space, preventing hot or cold spots. This can enhance comfort by maintaining a consistent temperature. Room Size: Larger rooms often require multiple vents to effectively heat or cool the entire area.
You can identify return vents by turning on the system fan and holding your hand or a piece of paper up. If the paper is pulled toward the vent or you feel a suction effect, it's a return vent.
Due in large part to the short cycling issues mentioned above, components on an oversized heating and/or air conditioning systems are more likely to fail sooner than those on a properly sized system. As a result, you may end up having to replace your HVAC system sooner than expected.
Crawl space vents are fairly easy to open and close. They are typically made of sheet metal, cast-iron grating, hardware cloth, or corrosion-resistant wire mesh. These types of vents can be opened to increase circulation in the summer and to restrict ventilation in the winter.
Return vents are usually larger than supply vents and are in large rooms in the home. The return vents in your home help equalize the pressure that changes as your HVAC system heats or cools your home. These vents should never be fully closed because closing them off restricts airflow and strains the system.
Instead, there should be at least one return vent in every room, with two or three being ideal. If your house has only one return vent, this is not a problem — make sure to keep the doors open in every room so the air can circulate properly. Make sure there are no furniture, draperies, rugs, etc. blocking return vents.
To maintain an even temperature throughout the room, return air vents should ideally be positioned higher on the walls or near the ceiling to capture the rising warm air effectively.
While return vents don't always require filters, adding them provides additional filtration, improving indoor air quality and keeping dirt and debris out of your system.
Well, they do pretty much exactly what they say; they return cold air back to your furnace to be heated and then distributed throughout your home. You will find cold air returns near the floor of your rooms as cold air falls. The returns at the top of your rooms are hot air returns, since warm air rises.
Symptoms include weak airflow and uneven cooling or heating throughout your home, with some rooms feeling much cooler or warmer than others. Homeowners should regularly check vents for consistent airflow. If you notice a significant drop in air pressure or uneven temperatures, it could indicate return air issues.
When it comes to cooling your home, return vents are best installed near the ceiling so they can draw in any hot air that has risen. Supply vents should also be placed high on the wall for better distribution of cold air throughout the room.
Restrictive vents or grills: A vent that isn't the right size or shape can make a ton of unwanted noise. Some vents aren't made very well and have very narrow openings for air to enter or have vents that fall closed easily, which means that the HVAC system or furnace has to work super hard to get enough return air.
Hot air rises and cool air sinks. Therefore, opening the right return vents in the summer and winter significantly improves the distribution of air by your forced-air system. You'll also enjoy more even heating and cooling throughout your home. In the summer, open your high returns and close the low ones.
Dirty filters, leaky ducts, and poor insulation can cause cold return vents. Leaky ducts often cause cold air to blow even after cranking the heat up. 20-30% of air, especially hot air, is lost because of leaky ducts. Cracked, holey ductwork needs sealing or replacement.
Use your trickle vents
By leaving your trickle vents open during the summer, air can travel freely throughout the home without letting in the hot and humid air as well as keeping out those pesky flying insects.
Sealing locks out moisture-laden air from the outside while insulation ensures the crawl space air doesn't escape to the outside. The result is a clean, dry, and temperature-controlled space.
Shutting the heating vents in your basement or another room you don't use very often is a great way to reduce energy expenses during the summer months. That being said, it isn't something you should do for more than two or three days at a time.
If your air conditioning system is too big, it cannot completely cool your home. This means that you'll have hot or cold spots throughout your home. An AC system that is too large doesn't run long, so the cool air can't be equally distributed through your home. This causes some areas to be cool while others are warm.
Up High: having an air return higher up on a wall will be better at sucking in hot air that rises. Making it more efficient at transferring this hot air back into your system to repeat the cooling cycle. Down Low: if you have your air return lower on your wall it will function better as a cold air return.
Dirty, clogged or overly restrictive filters may be the cause of many heating-and-cooling problems, including a constantly running AC system.
