Is it more energy efficient to use a portable A/C in the bedroom at night over central air
Posted on 7/9/23 at 1:26 pm

My central A/C capacitor died this weekend when all the part stores were closed. It got me thinking about buying a portable A/C.
It looks like I can buy one for around $400 in a 400 square foot room with around 6500 BTU. It looks like the average central air unit is around 30,000 to 50,000 BTU.
Does anyone use a portable A/C in their bedroom? I like to sleep with the temp around 68 at night. Is it more cost efficient to keep the central air in the upper 70s and just cool the bedroom with a portable?

Rookie mistake, always keep a spare onhand.

When my AC shite the bed a few years back we picked up two portable units since we don't have the ability to use window units. They will cool the room down but the humidity will be sky high to the point it feels wet in your bed.

If it's trashy trying to cut down on energy costs then consider me the trashiest of them all.

I have one in my bedroom that we bought for our RV. It cools our bedroom to 64 degrees and I turn the thermostat for the main AC in our house to 74 and let the kids sweat at night
And there’s a small vent that we ran to the window but it faces our back patio/pool area so nobody sees it but us

My capacitor from Amazon just arrived, so I'm good to go now. I may try to find a portable on Prime Day this week to have on hand though.

I don't think you'll have an issue with the humidity like I did if it is only to supplement the cooling in your room. How does she feel about cranking the AC down to 68 at night? Mine would absolutely be dead set against a temp that low, I'm lucky I can set mine to 71.

We put a split in our bedroom and it does help. We turn the house AC up to 78 at night and grand the BR down to the 60s

When i bought my house it had a window unit in the master bedroom. A/C was also also less than 6 months old. I thought, awesome we have A/C if we lose power since a have a generator. Within the 1st Month I cranked that baby up to 67 and slept like a baby all night. We have no kids in a 4 bedroom home. Every night the Window unit goes on and the AC unit is set to 78. Saves us a ton in the summer months.

This LG model works great in a bedroom. You do need to duct the hot air out of a window but it only takes a few minutes to modify with a mile or so of duct tape. Seriously, it works well with no noticeable humidity increase.

Yep. Our bedroom is on the opposite side of the house from our AC unit and where the sun beats down all day. For that reason, that side of the house is warmer than the opposite side.
We bought a window unit about three years ago, and though it’s technically against our HOA rules, I built a fake flower box around it so it isn’t visible from the street.
We run it on 65 every night and keep the main unit around 75.
I love the white noise from the unit and with the room being cold, I sleep much better. And since I work shift work, I covered the windows with wooden shutters which keeps the room dark as well.

bedroom is on 2nd floor, once she went off for college. The wife and I bought a window unit for our bedroom. Turn the central A/c off at night.

Your mileage may vary, but the portable unit I tried was similarly priced to what you're thinking about buying, and it was complete garbage.
ETA: Unless you're talking about a window unit, which is entirely different than the "portable" units out there these days.

Call me white trash if you like, but this is reason #2434 that I could never live in a place with an HOA.

I have a cheap window unit I left in the bedroom window after Ida and used it during the months where it was t hot enough to run the central but warm enough to want to be cooler, especially at night. It cools the room to perfection but it only has an on/off switch so it does burn a lot of energy. Get one that has a thermostat so it can regulate itself and it might be worth it.

It’s only a 24 house cul-de-sac neighborhood and the yearly fee is $75. They aren’t very strict. The fee is basically to keep up the neighborhood sign up front and mow the grass.

single hose portable units are trash.
If you want to know why, go outside where the hose is venting out outside. Feel how much air is being blown at you. Its a lot. All that air getting blown out of the house has to be replaced. That replacement air will come in through every crack and crevasse air can be pulled in from. Hopefully all that outside air being pulled in is only the 90 degree humid-arse ambient outside air. If its getting pulled in from the attic ( and some is guaranteed to be) its going to be 130 degree air.
On the surface, they seem to work like window units. Cold air blowing inside; Hot air blowing outside. The key difference is the hot air blowing outside on a window unit isn't coming from inside the home. Its outside air being pulled in from the sides and back out through the hot condenser. With those garbage portable units, interior air is being used to cool the condenser. This air exiting the home is causing the home to be under vacuum.
