Question for the ot a/c man regarding house temperature
Posted on 5/23/19 at 8:32 pm

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.

I think the bumping the AC up to save money is a myth. Something about cooling down thermal mass.

77 seems high... I could see bumping it up to like 74.

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.
But to answer your question, yes, a smaller bump would be easier on your unit.

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.

Just leave it at 73 or 74.
You’ll get used to it in a week or 2.

Depending on where you live, if you kept it on 74 during the day would it be running all day? I live in GA and if I keep my house on 74 then my a/c would constantly be running since it’s so hot during the summers.

I’m tellin ya I deal w AC peeps every week. The key is timing the fan.

Are you dropping the temp to 70 as soon as you get home from work, or right before the sun goes down?
Posted on 5/23/19 at 9:09 pm to TheAstroTiger
Either don’t go as high as 77 or don’t go all the way down to 70 when you get home. Go down to like 73/74 then down to 70 just before you go to bed. As the the sun goes down it will be easier on the unit.

The most expensive part of running an A/C unit is when it starts up each time. That voltage is super high, but it doesn’t take much to keep it running.
I just installed a variable speed compressor at my house and it can choke down to running as little as 5% and up to 100%. As long as it doesn’t shot completely off, I was told it was as efficient as possible.
I’ve always kept mine at the same temp no matter if the heat or ac is on. 68 in winter and 72 in summer. Electric bills are never super high so I feel good about my strategy.

I bump it up to 80° for the day.
But it only takes an hour or so for the temp to get down to 70°-72°.
Electric bill is much much less than letting it run at lower levels all day. And I’ve tested this for two years, each way.

Speaking of AC, I now have a thermostat that I can control via phone app. Can turn it down before I start home so that it’s already cooler when I get home.

Buy a dehumidifier. It helps your body operate more efficiently with humidity in the 50% range. You feel comfortable at 3 or 4 degrees higher than you normally do. Also it makes the AC work less because the cooling energy goes to cooling air and not condensing so much water.

Running doesn't stress the AC unit. Starting and stopping is what stresses the unit.
Nothing wrong with what you are doing.

It could be that your unit needs more refrigerant. Get that added to it and see if it cools down faster then.

It depends on how well insulated your house is.
Mine isnt insulated well at all so I see big savings by bumping up to about 78 during the day when I'm not home. Sleep with it on 70 because that's about the best it can do in the summer and runs all night.
My old house was well insulated and stayed between 72 and 68 all summer no problem.

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.

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.
