Recently purchased a home built in the 1960s. We have baseboard diffusers in 3 bedrooms that are getting carpet installed this week.
The diffusers are old and big and I was looking to replace them. They are 24 ½" long and the actual vent opening is only half that.
Is there a reason the diffuser would be so much bigger? I'm having trouble finding one of the same size and would like to downsize them if it's not detrimental to the cooling and heating.
Carpet is coming in a couple days so I need to figure out if I can rip them out and they can lay carpet assuming we'll have the smaller diffusers.
Here's images of what I'm working with:
