re: What temp do you come home to if the AC is off all day?

about guarantee its an urban legend. Heat transefer is going to happen at a more rapid rate when your home is at 78 and the outside is at 95 than when your home is at 85 and the outside is 95. It might feel like you're saving money but your really not. Leave it on for comfort, not savings.
Also, none of you fuchs have ansered my question. Half of you cant even read the OP correctly.
That and an AC "works harder" depending on how far it has to cool (outside of dual stage). .
No it doesn't. It's either on or off. It may have to "run longer." But it does not "work harder." If it freezes up, it's not operating properly.
Even still, it's less efficient to maintain a bigger difference in inside vs outside air, over time--the bigger the difference, the faster the heat transfer

No. You may not want to turn it up (or even off) while you're away, but it's not cheaper.

Ever since the creation of air conditioning systems, homeowners have been trying and testing countless AC hacks to save energy without sacrificing comfort. While some work, we have also been left with a handful of AC-related myths. One of the most popular myths is the idea that leaving your AC on throughout the day saves more money than turning it off while you’re out because your system doesn’t have to use excess energy every time you turn it back on. But this is 100% false. But why? If you’re keeping your air conditioning system on at all times—even when you’re not home—you’re not using your AC as efficiently as you could be. So although it may seem like your system will use extra energy to power itself on, this just isn’t true. The fact is that it is much more taxing for your system to fluctuate all day to achieve a consistent temperature. Unfortunately, when your AC is working hard to ensure your home is comfortable throughout the day it puts excess wear and tear on your system. The result? You’re left with higher energy bills and a shorter lifespan for your air conditioning system.

Not sure where you are, but Anchorage has been having record heat, 90 degrees yesterday. Forecast of 92 on Tuesday
Yeah it's hot. I'm in the Panhandle, Southeast part. It's been really warm here too. But 90 isn't unheard of for parts of Ak. State record is 99, and that was north of the Arctic circle.
We have a huge maritime influence in Juneau. Fairly mild all year

I installed 3 vent fans that remove the hot air from my attic. Helped a ton.
Posted on 7/6/19 at 10:20 pm to Chuker
I let the help keep it at 70
Posted on 7/6/19 at 11:10 pm to Chuker
So if hammertoe comes home and it’s 97 like today the house would be 92?

it costs more money to cool it down from 85 than it does to just raise it a little bit to a reasonable temperature
I’ve always thought this too but a 30+ year vet of the A/C business recently told me it wasn’t true. I didn’t ask for any hard data.

If leave my ac set to 71 during the day, I'll come home and it'll be 74 in the house and the ac running. It literally runs all day because it can't cool the house.
I turn it up to 77 and then it doesn't run all day. I turn it to 70 when I get home
Sounds like you have a slow evaporator coil leak, or unit is too small for house. AC should be able to keep up regardless.

75
Posted on 7/7/19 at 7:59 am to Chuker
shite my AC ran all day yesterday set at 74 and it still got up to 79 in my house. AC just can't keep up. Need a bigger unit or more insulation or something.

When you get accustomed to cool summers, even that will seem hot. I've noticed my heat tolerance dropping the longer I've been here.
My wife’s family is from Louisiana. Her sister moved to Wyoming about 15 years ago. She only comes down to visit now between November and March. She says she physically can’t handle the heat/humidity anymore.

the only real motherfricker on this damn website.
Amazing how many people called me a retard and blabbered about "humidity" and "ac working too hard". Hell I didn't even ask the question of whether or not you should turn it off during the day. I asked how much your home heats up this time of year if your a/c is off for the day.
Though in fairness, that is a kinda a silly question because of the many varying factors of a given home. In my case I get a ton of sun so a 10degree difference from morning till I get home is not bad at all.
Also, considering comfort to cost ratio, leaving it on so you don't come home to a hot house much more preferable to most people than saving a little by completely turning it off. I recognize that but because I live alone and have no life, just for the lulz I try and keep my electric bill under $50/mo so I take drastic measures .
But this thread is a reminder to take everything you read on here with a big grain of salt. People are all to happy to give advice even if they aren't sure about what they are talking about. I myself have have done this same thing from time to time.
Its also a reminder why I need to move out of this goddamn hot arse humid climate. Maybe Roger will let me sleep on his couch.......

You don’t turn off your ac completely during the day. I turn mine up to 77 so I come home to 77 and it doesn’t have to work so hard to cool down.
77? frick that. Mine stays at 72 all day while I’m at work. Can’t stand coming home to a hot house. My electric bill is never more than $130

Probably all of the above. It's a house built in 1992 with the original HVAC system
Posted on 7/7/19 at 10:08 am to Chuker
Why would you shut off your AC during the day? It is cheaper and more efficient to let it kick on at 78 than to shut it off, let the house warm, and then try cool it down at night. If your AC doesn’t kick off at all than it is either too old or too small for the house.

If Lennox unit, almost guarantee it's a leaky evaporator coil.

If i turned it off, it would go in the 80s and then take forever for the house to cool at night. I may turn it up to 78 during the day but i don’t turn it off when I’m not home

Carrier, I believe
Posted on 7/7/19 at 11:06 am to Hulkklogan
I have a 5 ton trane and it couldn't quite keep up yesterday. I had it set to 72 and it was 74 most of the day. It's been recently serviced so I'm confident it's working fine. It was just hot as hell and we were in and out of the house all day.
Posted on 7/7/19 at 12:51 pm to Hulkklogan
Carrier is pretty good and coil will last around 8 years. It'll cost a little more to repair if the unit is worth repairing.
I have a 4 ton for downstairs and a 3 ton for upstairs for 3887 sq ft and AC keeps up and cycles off and on regardless of temp. One unit is 7 yrs old and the other is a new 16 Seer 3 ton Trane installed last month.
Our old house was 2,450 sq ft with a 5 ton Trane and cycled off and on regardless of temp set.
However, insulation is key and relatively inexpensive. Just buy the 18"x48" Batts and lay right overtop of old blown in settled insulation. That'll greatly help.
Electric or solar powered vents in attic greatly help as well.
Attic stair tents help out tremendously as well if attic stairs near air return.
