Running a/c fan all night
Posted on 6/29/26 at 8:45 pm

Our house has the terrible problem of the air units barely ever run overnight, creates some stale air sitting in our bedroom. The ceiling fan helps some but I'm trying to come up with something other than buying a pedestal fan to help out.
Any issue with clicking the fan to on all night? My thermostat isn't fancy enough to tell it to run 5 minutes per hour or something.

It would wear out the motor sooner just because of run time.
No big deal. Just replace it when it does. Could take years and years.
I have house fans that run 24/7 for at least 14 years.

I'm specifically talking about the fan ont eh A/C unit. Right now it only runs when the compressor kicks on, I'm talking about running that fan all night.

I used to leave mine on all summer. No, there is not going to be an issue with it unless you already have an underlying problem. It made a big difference in my home, much better. You will go through more filters, but thats more crap being filtered out of your air. Very slightly higher electric bill but the blowers dont pull much. The temp in the house will stay more even and consistent with the constant circulation. The compressor will cycle more, which is a bad thing, but piss on it. Get a spare contactor and spare start capacitors and let it rip.
I now have a variable speed unit and the blower runs continuously.

Put a window unit in the bedroom and turn your main unit off for the night. It saves a bunch on electricity bill.

Right. I understand.

Usually not a great idea with typical duct in attic systems. Most houses have ducts that are leaking air. Most ducts are poorly insulated. Attics usually don't cool down until after midnight.
You're constantly picking up heat from the ducts plus losing conditioned air via the leaks--and that loss of air has to be replaced into the house somehow. That means humid arse June air working its way indoors via every crack and crevasse.
With a perfect sealed system that is well insulated for within the conditioned space? -- go for it.

The humidity will rise so much you’ll wake up in what feels like a rain forrest.
It’s 2026 - it’s time to upgrade your thermostat.
My unit is set to 70 at night and I have my thermostat settings to run on stage 1 for 40 minutes before stage 2 kicks in, which means the the unit runs longer before shutting off but it’s only running on about 70% of its full energy capacity so it saves energy rather than running for a couple minutes on stage 1 then kicking into stage 2 at full energy usage for 10 minutes then turning off for 10 minutes and repeating the process all night long (my unit is a little oversized). Plus the longer it runs on stage 1, the more it lowers the humidity in the house. Today’s thermostats have all sorts of settings that you can get ChatGPT to help you with. It’s very useful in my opinion.

If the ducts are within the conditioned envelope, yes. If not, buy a pedestal fan. I have a dreo that's very quiet.

My thermostat has some sort of settings to run the fan for 10 minutes per hour or something. Is there any benefit to this with our heat and humidity?

I've been doing this for years. I have no issues with humidity, and my ducts are in my attic.

You can get a cheap digital thermostat that will run the fan only randomly throughout the day which is what I have.
Before I updated a bunch of stuff, like windows and door seals, my house would get a lot of condensation on the inside of the windows during the winter. I would run the fan on random all day, and it helped cut down on the moisture.
Or you can get a portable AC unit from Home Depot for the rooms that feel stale.
Putting a fan in the doorway is probably the cheapest option.

Certainly an idea worth looking into - upgrade your thermostat to one that offers a “circulate” mode where the fan will run for a designated amount of time every hour when there is no call for cooling.
What I don’t is how much programming flexibility, is provided in “circulate” mode among those thermostats. My smart thermostat (Honeywell) has that circulate function though I never use it. Ecobee, Honeywell, Sensi - all good smart thermostats - have models with that function.
