Re: Relocating a return air vent

As “general rule” you want Return vents to be across room and “opposite” from Supply vents. Thus, if you have Supply vents down on floor, then you want your Return to be up high (this is most common).





Also, can you move a cold air return vent?

Relocating a cold air duct. If you have to move the duct over, do so in the basement but do not move it close to the hot air grills or you will create a short circuit and the hot air will just return to the furnace without going through the room.

Also, where should the return vent be located? 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.

Additionally, how much does it cost to move a return air vent?

Move an exhaust vent Costs. For your project in zip code 98104 with these options, the cost to move an exhaust vent starts at $549.26-$658.97 per vent. Your actual price will depend on job size, conditions, finish options you choose.

“If your ductwork is over 15 years old, you probably should replace it. Ductwork has a maximum lifespan of 20-25 years. By 15 years, however, it begins to deteriorate, significantly reducing your HVAC system’s efficiency, so replacement is the prudent option.”

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.

How do you reroute HVAC ductwork to remove walls?

Detach the connection where the flexible duct meets the circular end of the rigid duct. To do this, cut away any duct tape with a utility knife, then loosen and remove the duct screws. Pull the section of rigid duct out of the wall. Save this piece.

How much does it cost to reroute ductwork?

New ductwork for the home costs $10 to $20 per linear foot, including $1 to $10 per linear foot for materials and $5 to $10 per linear foot for installation.



New Ductwork Cost Per Square Foot.
Square Feet Linear Feet of Ductwork Price
3,000-4,500+ 350 $3,500-$7,000

Is it OK to block a cold air return?

Without that steady stream of incoming air, your unit won’t be able to work as effectively. 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.

Does every room need return air?

Your Home Might Not Have Enough Return Vents

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.

Why are air vents on the floor?

Floor Ducts

Heated air is less dense than cold air. That’s why heat rises. Floor ducts are effective because they deliver heated air at floor level. Floor vents are typically used in homes where the furnace is in a basement or the ducts (the piping from the furnace) travel through an underground crawlspace.

How do you know if you need new ductwork?

Some of the most common signs you should replace your ductwork are old ducts, high utility bills, and poor indoor air quality.
  1. Old Ductwork. The ductwork in most homes lasts between 10 and 15 years before problems arise.
  2. High Utility Bills.
  3. Poor Indoor Air Quality.

How long does flexible ductwork last?

50 years

Where do you put AC vents?

Supply register vents should be in every room as well. Located on the outer walls, under windows, in the ceiling, or on the floor, placement depends on the heating or cooling system as well as the construction of the home.

Can I replace my own ductwork?

Yes, having punctures in your ductwork due to pests is something that necessitates getting those ducts replaced, or at least repaired, and, yes, it is also a really tough job for you to take on yourself.

How much does it cost to install ductwork in an old house?

Expect to pay $35-$55 per linear foot (including labor and materials). This amounts to an average of $1,000-$5,000 for a typical home. An average single-family home needs anywhere from 30 to 90 linear feet of ducting, but the specific total length depends on your home’s unique layout.

How much would it cost to take radiators out a house and put central air?

However, the cost of a full central heating system ranges between $4,000 and $20,000. Just know, the maximum price includes extensive ductwork. The maximum cost reported for central heat installation is $20,000. The minimum reported cost of central heat installation is $4,000.

How big should a return air vent be?

Calculate the square root of the total. (Example: 4 (ton unit) x 144 square inches = 576 squared. The square root of 576 is 24. Therefore, your return air duct and grill size will be 24 by 24 inches.)

What is the difference between a vent and a return?

The biggest difference between supply and return vents is the direction in which the air flows. In a supply vent, the air flows out of the ductwork. In a return vent, the air flows into the ductwork.

Should I put filters in my return vents?

Do not put filters in your supply vents. Your AC system should have a proper fitting filter on the return side. By placing a good fitting, high quality filter on the return vent, you will remove particles from the air before they can enter the AC system.

Can you have too much return air?

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.
