How do you install a return air vent in a ceiling?

How to Install a Return Air Duct

  1. Locate where you want your return air ducts.
  2. Go into the basement and locate the holes.
  3. Install the square return air duct perpendicular to the joists.
  4. Cut a hole in the bottom of the return duct next to where the furnace is.
  5. Install your HVAC filter into your filter rack.

Likewise, people ask, can you put a cold air return in the ceiling?

If you are in the far north, or in the Southern US, the answer is simple. In an air conditioning climate the return duct goes near the ceiling to draw off the hot air and cool it down. In a heating climate, the return duct goes near the floor to draw off the cold air and heat it up.

Also, where should the return vent be located? Supply air from furnaces and air conditioners should be on outside walls. The return air vent openings need to be on the opposite side of the room so the conditioned air is pulled across the room. If the supply ducts are in the floor, then the return air should be located up high. This pulls the air across your body.

Subsequently, question is, which direction should ceiling return air vents face?

If you have an Air Return is on the upper wall I like to slant the louvers upwards so that floor traffic does not view into the duct opening. That is the same with Supply vents as well IF you have adequate air flow and few cold or hot spots in the room from inadequate air flow or distribution.

What happens if you block cold air return?

Blocking your cold air returns, whether intentionally or by accident, can be disastrous in more ways than one. Here’s what could happen if one or more of your returns are blocked: It can cause the evaporator coil to freeze over. The evaporator coil’s job is to absorb latent heat from air flowing over the coil.

What is the disadvantage in having ducts in the ceiling?

Ceiling ducts cannot be used with radiant heating systems, which generate heat from the floors. Ceiling ducts are more visible than floor ducts and harder to camouflage. Since heat dispersed from ceiling ducts reaches the upper air first, the HVAC system has to work harder to push the heat lower into a room.

Can you have too much cold air return?

While there is no such thing as too much return air for the equipment (actually, there is, and it causes fan cavitation, but very rare), this CAN be an issue for the house. It has the potential to throw off pressures in different areas of the house.

Does every room need a cold air return?

DEAR TIM: Ideally you want to have cold air return registers in every room. If you can’t easily install a true cold air duct back to the furnace from each room, you can sometimes fake it. You can install a cold air return register above the door from each room that connects to the hallway.

Should air returns be high or low?

Efficient heating means installing a return at a low point on the first floor, to capture cooled air and return it for heating. Registers that deliver warm air should be in the floor or low on the wall; registers to deliver cool air should be installed high up on the wall.

How many cold air returns should a house have?

Having several return vents (ideally one in every room, but even two or three is better than just one) creates consistent air pressure. If you have one return vent, your home is fine. Keep the doors to each room open so air can properly circulate.

Can a cold air return be in the floor?

If you are in the far north, or in the Southern US, the answer is simple. In an air conditioning climate the return duct goes near the ceiling to draw off the hot air and cool it down. In a heating climate, the return duct goes near the floor to draw off the cold air and heat it up.

Why is my room so hot compared to the rest of the house?

Closed vents—Closed vents in rooms can cause them to be hotter than other rooms. Open windows—Your conditioned air can flow out of open windows, leaving uneven temperatures in your home. Air duct issues—If you have any kinked or crushed supply ducts, certain rooms won’t get enough air.

Is it better to close vents in unused rooms?

Despite that logic, it’s actually a common misconception that closing vents in unused rooms saves energy. In fact, it can actually waste more energy than operating your system normally does. The added pressure from closing a vent can cause air leaks in your system, causing long-term and unnecessary energy waste.

Should return vents face up or down?

Heat rises; cold drops, so aim highest as it will eventually go down (conversely for warm air). aqnd wrote: Aim it upwards. In homes with central AC, vents are typically on the floor pointing upward for the reason you mentioned. You want to displace the hot air up top and hopefully get a current flowing.

Should you close doors in unused rooms?

Should You Close Doors in Unused Rooms. In short, the answer to this question is no. Although closing off unused rooms may seem like a way to save energy on heating and cooling, it can actually force your HVAC system to work harder.

How do you increase return air flow?

3 Simple Ways to Improve Your Furnace’s Airflow for More Comfort Unblock and clean your vents. Here’s a super easy way to increase air flow. Change your filters and clean your return grill. A dirty air filter impedes air movement and makes it hard for your furnace to work efficiently. Seal leaky ductwork. Snap on some goggles and a dust mask, it’s time to check out your air ducts.

Does closing vents make other rooms colder?

Blocking vents in certain rooms will make those rooms colder. Because heat moves from greater concentrations to lesser concentrations, these colder rooms will draw heat from other rooms in the house, making the whole house feel colder and causing you to raise the thermostat.
