In your area, if someone switches to a conditioned attic, what approximate percentage of the annual electric bill will they save?

We don't have our HVAC unit in the attic in CA but the ducts are in the attic. So maybe not as dramatic but those ducts heat up most likely. I wonder if this really means is a radiant barrier on the roof ceilng along with the insulation on the ceiling.

Not only is this more expensive but you also gonna need a erv/hrv plus a dehumidifier witch add thousands to the bill??

I'm shaking my head and almost laughing at the claim in the video description. A conditioned attic means a greater volume of air to be conditioned. A conditioned attic means you have a larger surface area to insulate to slow down heat transfer. That's definitely less energy efficient. Of course if you MUST put your HVAC in the attic then you want to make the attic conditioned for what I believe should be obvious reasons. The winner is definitely an unconditioned, vented attic on a house that has a proper air seal. And here you're talking new construction, so a proper air seal would be easy to do compared to a renovation.

Agreed…..more square feet to cool(more expensive). Most likely need to size up an AC unit(more expensive). No where for it to escape through ventilated roofs. Roofing materials must take a beating with this way of doing it. Matt Reisinger also mentions this in a couple of his videos….just wonder if these guys will ever give us real world results after a couple years? Be nice for someone to post that owns a conditioned attic.

The ducts are normally insulated too. Why insulate the whole roof and air condition the whole attic, if the ducts are insulated.

Not a "conditioned attic" just more insulated and unvented attic. Its common here in California pretty much a standard to have new roofs require insulation below roof deck for T24.

This is way more expensive, and what happens when you have a leak? Any builder with a triple digit IQ is not going to put HVAC in the attic. Unfortunately, there are a lot of bad contractors. Your heating and cooling is going to be more expensive too because you have way more space to condition.

@@ProductKingReviews I live in Carrollton GA in a home built in the 70s and I have a passively vented attic, and there is no HVAC equipment in my attic. In a vented attic, the only thing that should be up there is large amounts of insulation.

@@HTHAMMACK1 I’ve been in over 7,000 attics in the last 9 years in South GA near Savannah. I’m Not a hvac tech but my job requires attic work. At least 95% I’ve ever been in the Air Handler is in the attic and the HVAC unit is on the outside next to the house. It’s just how it’s done. The other 5% can vary, sometimes it’s in a closet like in the hallways or near the laundry room. My grandma actually had her air handler in her hallway in a closet but it’s very rare.
