Bought two of these for the summer months and I leave my AC on at 75 throughout the day. My bill, for a 1500 sq ft house, hasn't been over a $100/mo. I have one for my bedroom cause I like it frigid when I sleep and one for my kitchen/living room area when I cook cause it gets hot.

I think the bumping the AC up to save money is a myth.
It has saved us money, but we also run ceiling fans on high all day and bought better curtains and blinds for the windows that get a lot of sunlight. The monthly savings is only about $5-$10 though.
Thermostat is set at 71 from 3PM to 7AM, and 78 from 7AM to 3PM during the week. We keep it on 72 on the weekends when we are home.

I can’t sleep well unless it’s 68-69

What puts more stress on an ac unit:
I currently sleep with the ac on 70. While I am at work I put the ac on 77. When I get home I bump it down to 70 and it takes it about. 2.5 hours to get to 70. The unit is running constantly for 150 mins.
Would it be better for the unit to keep the ac on 74 during the day which would probably only make
The unit run for an hour to get to 70.
If my question is not clear let me know and I’ll try to think of a different way to ask.
Brah! Are you serious? Your A/C running for a STRAIGHT 150 min?
If this is central air, your A/C is low on freon and the fan in your attic is probably broken.
A good central air A/C unit takes around 10-20 min to bring your entire house temp down from the 80's to the 70's. Your AC if in the attic put out a lot of heat to be running. THere is a fan up there that is suppose to siphon most of it out otherwise you get upward of 160 degrees in your attic that is heating up your home while your A/C is simultaneously tryin to make it cool, which in turn extend the cool time.
Your third option is that your A/C tonage is not correct for the size of your home.
Final option is that you have a lot of cracks in your home bleeding out the AC or the insulation in your wall is either all super old now or too thin to do the job properly.

I leave mine at 78.
It is comfortable
No, it isn't, and people do not like to come to your house.

In doing some quick research it looks like it takes 3 hours to cool a moderate sized 4 bedroom house by 10 degrees. Taking 2.5 hours to cool 7 degrees fits in that stat. Being that we have been in the 90s in Louisiana, that seems incredibly realistic being that the air is turning down when heat level outside is at peak.

Yea I should have mentioned that my AC unit is only a year old. It should be operating fine. I guess I will keep doing what I am doing. I left it on 75 today.

It could be that your unit needs more refrigerant. Get that added to it and see if it cools down faster then.
Or the house needs better insulation, or he needs a bigger unit.
a lot of variables here. Posted on 5/24/19 at 12:13 pm to TheAstroTiger
This is an interesting thread and once again reminds me of how many people think they are extremely knowledgeable about things they obviously have no clue about.
Thank you for posting

Definitely does not need a larger unit. Almost everyone has oversized units.
When it is hot, a properly sized unit will be running 95-100% of the time. Units that are oversized start and stop too much reducing their lifespan AND efficiency. Most of the inefficiency of the cooling process is during the first few minutes after starting until it gets to a steady state.

thats why i always cringe reading these threads, its like the people responding have only lived in 1 home or apartment their entire life.

I'd say that is likely true but I have seen lot of older homes, in particular, that have slightly undersized units. If he has had a newer unit put in lately, there is a high probability that his contractor verified that the unit was adequate.

Better insulation can knock that down a bit.
quote:Can't emphasize enough how true that is on multiple counts. Additionally, a unit that constantly cycles and doesn't run long enough at a time may mean your humidity in the house is poorly controlled, which is not good for anything.

I have done the calculations and I can't see where bumping the temp up during the day saves more than a percent or two overall.
What calculations did you do exactly?

There is so much cringe worthy stuff in these. I really just get a kick out of it. ANd I may have inadvertantly added to that at times

You could probably bump it up to 74/75 and leave the fan on when you’re gone. Crank down a few right when you get home and leave fan on for a little bit. Then ease down to 70.
Fans don't cool the room. They cool you.

I'm probably in the minority here... but i saved 40-50 dollars a month on my capital heights house (zero insulation) by just turning it off in the summer. 70 at night when i got home.
With no air moving it seemed to heat up slower during the hot summer. It usually hit about 80 or so in the house at 5pm.
With air moving (ac on) it seemed to run all day and usually would get to around 77 anyway.
SO... there that.

You might think these are saving you money but portable a.c. like this are absolute garbage for most climates.
While its running, go outside and feel how much air is exhausted out the hose through the window. Now ask yourself, "if all this air is coming from inside the house, where is the air coming from that is replacing this exhausted air?".
The answer is that its coming from the humid and hot outdoors through leaks in the house envelope. Or possibly even worse, its drawing from an insanely hot attic through leaking light fixture penetrations in ceiling.

My new house in Tara has brick and slab. We turn it up to 76 during the day (barely runs) and 70 around 9pm (it runs for an hour or so and everything is perfect by the time i get home.
Saving money every month doing this.
Turning the fan only heats up your house with the attic heat in the ducts being a heat transfer with the fan pushing into your home.
