Pre-cooling while on the time of use/demand rate plan, has saved us tons of money! ❤

@cooa9951 Ай бұрын

Pre-cooling works great but all the money saved went to rate increases so we really don't see any savings. Too bad. We pre cool to 76 then at 4PM bump it to 82. Most days it does not reach 82 by 7PM. At 7PM it goes down to 78 for the night, 77 if its humid. I did add some blown in insulation in the attic and it helps.

We have a home built in 2014. No pre-cooling for us! We started last year turning our AC to 85 from 4-7, it never comes on during that time as it doesn't get that warm inside our house. The rest of the time it's set at 80 and both my husband and I are comfortable. We are also on the budget plan. Seemed to save us quite a bit, but basically our AC is off during those 3 hours.

With all of the testing that I’ve done in my older Scottsdale home I have concluded that pre-cooling or super cooling is not effective at all in fact it uses more energy than just staying at one steady temp, with the way these older houses are built, especially mine within the first hour of on peak usage 4-5pm it doesn’t matter how cold the house is going into “on peak” as soon as the temp is raised the house warms up within the first 30 minutes and then the AC continues to run constantly racking up the bill.

I hear you. I live in Yuma - when you get temperatures as high as 120 you don't leave your A/C at 70!! I would freeze if my house was 70! At night I cool it down to around 72 so I can sleep, but daytime it's set at 83 or maybe 82. Some of these people evidently don't live in Southern Arizona.🥵🌵

Right, or Arizona at all!!

I feel keeping the temp at an even resonable temp would save more energy. If its 110 outside and between 4 and 7 your home gets into the high 80s, then the 7 o'clock kick down starts, the AC doesnt stop running all Flippin night. How is this helping? We never set thermostat lower than 76 at night but that hottest part of the day plays havoc on the AC. Just BS😢

@@KathyBarnes-se5kv I agree with you! If I turn my air up to 85F during 4-7pm then by 7pm it WILL run all night to get it down again. But if I keep it at a constant 80F then it usually shuts off at night. Pre-cooling doesn't work.

It depends on many factors: your home’s insulation, components (tile and hard surfaces hold the cold better/longer), window efficiency, A/C units age/efficiency. And if you are on a TOU with DEMAND plan, supercooling definitely helps. It’s that DEMAND CHARGE that’s the killer, and a lot of people don’t understand how it works. We’ve lived in Goodyear (definitely southern AZ), and it took us a few years to figure it all out. 76-77° at night, we start cooling to around 72° up to the peak time (4-7 pm). Off/way up from 4-7. It doesn’t usually get warmer than 78° during those hours. We do this to a lesser degree when away for travel, to avoid that demand charge. Our bill is $141/month on level pay (just increased from $125, before that it was $115). Worth it for us. 3,000 sq ft home, 2 stories/2 AC units, no pool.

It's great advice, however you home needs GOOD insulation (regardless of pre-cooling or not), because... the greater the difference in temperature between the outside and inside of your home causes heat to flow more rapidly (thermodynamics 101), so if the insulation is poor then heat escapes faster. This includes double pane windows, and a lot of insulation in the attic. Stay cool!

I keep both of my a/c units at 78* the entire summer, sometimes turn it up at nite. I would freeze at 70*. I guess whatever works for each home !

I leave mines at 78 all day and night. Works for me . 😀

@charliebyerly3931 0 seconds ago I tried cooling starting at 5:30am right before the sun hit the house and yeah it got cool until about 10-10:30 and then the temp in the house just started going up and up, no matter what its set at. Since then Aug 22, I replaced the South facing roof with a white Cool Roof hoping it would help... Last year it was 87-90" in here even tho it was set at 80. So far this year, I'm doing 78 until 10, then 76 until 4pm, then its 80 and set back to 78 at 7:30 and its working so far, but its only end of May. Heat pump can only do about 20° cooler than outside temps, so come July it won't be able to stay 80 in here. A Honeywell Turbo Fan saved me last year tho. Keeps me cooler. Also I keep juice popsicles, cheese sticks and tube yogurt in the freezer to help cool me down. House built 77-81, still have builders single draft pane windows and drafty doors

@craigcarpenter6535 Жыл бұрын

it would seem you would use more energy running the AC for 8 hours at a 73 temp then just setting it at 79 all day long, thoughts

@MrThermoBob Жыл бұрын

You might use more energy as you point out, but that’s not what you’re charged for. You’re charged only a nickel per kilowatt hour in the off-peak hours but are charged three times that much during the on peak hours PLUS the demand charge which can easily be an additional hundred dollars on the month. Having a low demand for the entire month is what cuts our bill to a year-round average of $152 even though our home is 3700 ft.².

@charliebyerly3931 4 ай бұрын

Yeah I was on the old 9am-9pm time of day deal, that was impossible. Then was on same price all day/night which was like 11¢ until they raised rates a few times. Just went on this new demand charge 2 months ago. First bill was $60 (half the month of demand deal), then $25.25, next was $80.58. I dread the summer bills. I read you can ask for demand charge to be removed once a year if its too high. I'm on low income discount too... Need to make the discount higher if they keep raising the rates!

Super cooling does not work with an older home as I have had my home Weatherlization done everything I keep mine like a lot of my friends at one temperature I had a lower it this year and it stays at 79 if you're super cool it turn it off turn your air conditioner on again you're working it much harder so this works for newer homes from what I've seen and heard not with older homes and I had everything updated keep it at one temperature

Hi, Theresa. Just to clarify, APS does not suggesting to turn off your air conditioner. That is just what some customers do. We suggest to cool at a lower temperature and then when On-peak starts, raise the temperature to 78 to 80 degrees, or higher if you are comfortable with a higher temperature. On-peak hours are only from 4pm - 7pm on weekdays. You can learn more about precooling at aps.com/precool and by visiting our site at aps.com/save. We appreciate the opportunity to serve you.

Actually it works. I keep my house at 74 then around 3 I lower it to 72. At 4 I turn it to 80 and get the fan going. At 7pm I turn it back to 74.... And my bill is pretty consistent and doesn't go above my usual expected summer bill.
