Don't waste all that cold air in your ducts, switch your fan to constant so that

I set mine to do that about a month ago hoping it would help balance the temps better across the house. I think it might

in high humidity areas it might introduce more humidity, as the coils aren't

My ducts are in the attic. Running constantly pulls heat from attic and warms the house. My ecobee learns how long it

Seems like modern smart thermostats could keep the fan on for a few minutes after the AC cycles off

They do

Going through my ecobee settings and I don't see anything about it - does it just do it

Skeptical Optimist

I don't see it on my Ecobee either.

It's called "Cool Dissipation Time" and it is defaulted to Auto. But you can change it to a specific time.

supertux

Jul 4, 5:14pm

Actually it looks like the default is 30 seconds. I have mine set to Auto.

supertux

Jul 4, 5:16pm

I'd bet after 30 seconds the air coming out is still blowing cold, but your fan

When set to Auto the thermostat detects the optimal dissipation time and uses that.

Interesting, mine doesn’t have that setting

Skeptical Optimist

Jul 4, 6:04pm

It's possible that newer models didn't let you change it. Or maybe there's another setting you have to enable to see it

supertux

Figured it out - you have to have configure staging set to manual for it to show up

I had seen that somewhere. Seems weird that that is required.

Mine either

Another cool feature of modern thermostats

Jul 4, 5:41pm

My ecobee doesn't do that. At least not automatically. It does have a setting to tell it to run the fan a minimum number

honeywell does

Jul 4, 5:48pm

Yeah I have a couple of sensors for mine. The main benefit is that my thermostat is in a hallway that gets almost

Have you tried Airtap AC Infinity?

RUNBYU1

Jul 4, 7:08pm

Looks interesting. Getting power to it seems like it would be tricky.

supertux

Jul 4, 7:15pm

Only if you don’t have an outlet within 10 feet of a vent in that room

RUNBYU1

Jul 4, 7:23pm

Yeah my vents are all in the ceiling. I'd prob have to find a way to run the power up into the attic.

so just using your lungs instead of the $5 filter. 😉

Well, I think it's worth a try to see if there's a noticeable difference, for me

BYUFBDAD

Jul 4, 5:17pm

It isn't universally recommended. There are pros and cons.

supertux

Jul 4, 5:19pm

that's exactly what I said in my post. And your link compares keeping it on

BYUFBDAD

Jul 4, 5:21pm

The point is, there are tradeoffs to keeping it on even when the AC is off. That post discusses them. In many cases

supertux

Jul 4, 5:29pm

These are the downsides listed on your link

BYUFBDAD

Jul 4, 5:46pm

Correct

supertux

Jul 4, 5:47pm

It sounds like you re very pro "run it in constant mode" and have already made

Jul 4, 5:48pm

I see what you're trying to do here, but it's not similar. Nice try.

BYUFBDAD

Jul 4, 5:50pm

It’s different, sure

Jul 4, 5:51pm

I think what's happening here is those of us who have spent more time than we care to admit looking into these things

supertux

Jul 4, 5:54pm

No, this seems to be personal with NanoFab Coug.

Jul 4, 5:59pm

I don’t know what you’re talking about. That’s pure coincidence.
