I understand from a little research that the installer used the joist for panned return. But what is this box and is it necessary? It's creating quite an obstacle to framing and sheet rocking ceiling (not sure why pictures uploaded upside down) Thanks!

Hi there, I've just finished skim coating and painting a bedroom in my house. I'm now in the process of doing some of the detail work at the end like putting registers back on the walls for the return air intake. I am having some trouble finding a way to put a register on this opening because...

I'd like to relocate an existing return air grille. Can I use 10-in. z-flex or similar semi rigid duct? It's about 8-10 feet directly back to the air handler. OK to pipe in right before the return filter on the air handler? Seems like the one home HVAC job I'd handle myself. Good supply house...

Hi, Is it possible to find these and purchase replacements return air grill latches, and if so, can someone point me in that direction? Existing ones have been broken and I'm running out of latches to hold the grill up, and would rather not replace the entire air return if I didn't have to...

I hear a lot of blower noise in my living room. When I moved in, I got an HVAC contractor to add AC to the existing forced air heat system, and he said the problem is that the return air duct is just too short. Houses around here (1950s neighborhood, San Francisco Bay area) didn't originally...

In the process of renovating my house and finishing my basement. I plan on having an Audio Video equipment closet under the stairs that may become warm due to the equipment within. Is there any reason I should NOT add a small extra return air vent to the closet (there is no supply to the...

Hello, I am a long time lurker and new member here. I am remodeling the laundry room in my 1954 house. As part of the renovations, I am rebuilding a closet around my furnace and hot water heater. After removing some very poor ceiling patches where the return duct penetrates the ceiling, it...

I'm to get some good piece of advice on a project I'm thinking about doing. I have a 12' wall in my dining room with two 27 inch windows. In between the windows is a wall with a cold air return near the floor-- a small one -- my house is old and doesn't have a central cold air return with a...

I am removing a wall between the master bedroom and spare room, can I just "cap off" a return vent in that wall or does it have to be rerouted? The master bedroom already has a return vent.

I Am installing an Goodman 69k btu furnace in my home, I am wondering what would be the standard return air requirements, I will be cutting out the sill plate and floor on a partition wall i am not sure if one stud span will be enough. I will be using a regular filter. Thank You very much for...

Thanks to BT I have located a 10" stud space to install a transfer grille system from an upstairs bedroom with no return air to the adjoining hall, however the nearest return air is across the hall behind the door in the opposing bedroom. Several questions: 1. My existing returns in the...

I am replacing my 41" tall, low boy furnace shortly with a Carrier Infinity 80BTU. The Return air duct on ceiling is 10" x 20" fed from the underside by a 12 x 20" X 90 degree turn which offsets sideways from the cold plenum. See attached .This 12 x 20 x 90 degree offset measures a total of 18.5...

I have a 18x18 return air grille on my dining room wall. I'd like to replace it to 18x16 for a cosmetic reason (so only the height will be two inch shorter). Can it bring any harm to my furnace if I make the replacement? It's only two inch difference, so I'm hoping/guessing it will be fine. Will...
