A Trick to Save You Money on Your A/C this Summer

Many of us are looking for ways we can trim a little fat from your budget. Have you thought about how you can save money on A/C?

No, I’m not talking about being miserably hot this summer to save a few bucks. I am talking about something you can do today to start saving you up to 33% each month and even cooling your house more. It all happens at your thermostat.

 

Thermostat

I live in Phoenix, Arizona, where the sun is out 99% of the year and the average temperature in the summer months is over 100°F. It is literally so hot, you can crack and egg in the street and it will cook (please don’t eat it).

Last fall I stumbled upon this wacky idea about cooling my house down to 74°F and saving money!

Since I think I know everything, I decided to try it out to prove my informer wrong. Not only was I mistaken, but I was completely shocked with our savings from this same time a year ago. Check out my actual bill from June 2015 below:

How to Save Money on Air Conditioning Bill

Step 1: Call Your Utility Company

Call your utility provider and ask about time advantage plans. Many of you already are doing this, but if not, call and ask about a plan available for on peak versus off peak times. Here’s how a typical plan works:

 

  • The plan is billed on an off-peak and on peak basis
  • off-peak hours are weekdays from 7 pm to noon and all day Saturday and Sunday, as well as 6 major holidays (these times will vary depending on where you live)
  • on-peak hours are weekdays from noon to 7 pm  (these times will vary depending on where you live)
  • electricity used during off-peak hours is billed at a lower rate

 

We are on the Noon – 7:00PM Time Advantage Plan offered from our utility provider in Phoenix. This means we are on peak for those 7 hours, so we limit the usage of our major appliances.

I know what you are thinking, “What about A/C in the Summer?”. Don’t worry, it’s coming 🙂

Step 2a:  Set your Thermostat

Set your thermostat to 80°F from Noon – 7:00PM and 74°F from 7:00PM until Noon the following day.

 

Step 2b: Buy a Programmable Thermostat

These things used to be pricey, but you can find them the cheapest on Amazon. They are also extremely easy to install, but just in case you may want to make friends with your handy neighbor (the one with all the cool tools).

 

 

Step 3: Save Money and Sleep Under the Covers

How Does This Actually Save Money on A/C?

A friend of mine in the cooling and heating business explained this to me so I could understand it. Here is what he said:

 

“A jet airliner burns the majority of its fuel during takeoff. This is also true for your A/C unit. Every time your unit starts up, it draws a bunch of electricity to power on the compressor. The less your unit turns on and off, the more money you’ll save.”

 

The goal is to get your unit to turn on and off less. 

You just did this by adjusting your thermostat to the settings above. The unit turns on after sunset and runs for a while. Your house was at 80°F and it’s bringing it down to a cool 74°F. This may take a while, but remember it’s going to be on continuously.

The next day at Noon, your thermostat goes back up to 80°F. For the next 7 hours, your unit may only turn on once because your house will slowly warm up to 80°F. Also, this is the most expensive time of the day (on peak), so this is double savings – not powering up as often and staying off during the most expensive time of day.

Three Other Utility Tips

Why we are on the topic, here are some things you should be trying out to save money and to make your life easier.

    1. Equalizer – Most utility companies have a program where they average out your monthly usage over the year and then use that average to keep your bill the same every single month. This will help you out tremendously when you are trying to do your budget.Before we did this, we would have to look back from the previous year and guess on how much electricity we would use for the upcoming month. Now we know to the penny how much our bill will be each month. When you are using the Money Peach Spreadsheet Budget, utilities are now moved into the orange part of the budget that remains the same each month. I like simplifying my life and money.

 

 

Don’t Know How to Budget?

Let me send you our most Powerful Budgeting Tool and even show you get started!

  1. Phantom Users – Phantom power users are devices which are using power 24 hours a day whether they are powered on or off. They may be powered so they can be turned on by a remote control or a timer. Individually, they are merely interesting to talk about in terms of saving you money, however an article printed in Forbes Magazine explains:

 

An individual product draws relatively little standby power, but a typical U.S. home has forty products constantly drawing power. Together these amount to almost 10% of residential electricity use.

If you are looking to save money and cut back on COemmissions, unplug what you aren’t using. Television related equipment (cable boxes, DVRs, DVD players) and computers draw the highest percentage of electricity – start there.

 

  1. Look for the Energy Star – If your appliance is working fine, there is no sense in buying a new one. I am trying to save you money. However, if you NEEd a new washer, dryer, hot water heater, oven range, or refrigerator – look for the energy star. These appliances were designed to save energy consumption for the environment, with a side effect of saving you money as well. Double win!

    Love this! Bryan and I are on the 12-7 plan too. I always wake up and turn our thermostates up to 80 but it makes more sense to keep it at 74 until noon!!! We will be purchasing programable thermostates ASAP and enjoy the savings and cooler house!!

      Hi Samantha!
      This great news! One thing for you and everyone else reading this comment is to pay attention to your programable thermostat. Some of the newer thermostats are so fancy, they actually make it a little tricky to set up your schedule from 74°F to 80°F. Why is that? Well, these fancy ones are “smart” and if you tell your house to cool to 74°F at 7:00PM, it will actually collect data over the week and make sure your house is AT 74°F when the clock hits 7:00PM. This means your unit(s) will turn on prior to 7:00PM. It is called “Recovery” and will be displayed on your thermostat. There is a way to disable this by reading through the instructions or looking online. Just FYI 🙂

      If you are with APS, that was an older time advantage plan they don’t offer anymore. If you were in it before they phased it out, then you’ll remain in it. We were on the 9am – 9pm plan too, but since I knew we would want to start cooling our house BEFORE 9pm, we moved to the noon – 7pm plan. If I am in your shoes, I’m moving over to the noon – 7pm plan and using the 74°F and 80°F temps for noon and 7pm. Great question Sean!

    We do something similar with our AC. Everyone always asks, “Won’t that burn out your AC unit?” when they hear what we do? I like your description on why it works and will have to make sure I link back to this from my post I made a few weeks ago about it.

    Hi I also live in AZ. I love this idea, and think it would be very helpful. I called my electric company and unfortunately they don’t do this for us. They charge a flat rate for any time of day so it doesn’t make a difference. Bummer* I do appreciate you sharing this tip and all the others with the rest of us. I found this page just last night and I’m already loving it!

    How would you do this is your house has 2 units? Set them both on the same program? What about Saturday and Sunday?

      Hi Charissa!
      We have 2 units also and we set them both the same. On the weekends, we pick a temp that is comfortable for us (75°F) because it doesn’t really matter – there isn’t a “trick” to save money on weekends or holidays.
      Great question and thanks for reading MP!

    Hi Chris,

    I am always looking for ways to save money and saw your post on electricity. I was alway told it wasn’t a good idea to set the thermometer the way you are doing it but after reading your post it makes perfect sense. I am going to try doing this as we have a programable thermostat. We have a single level home about 2150 sq ft. How did you decide on 74 degrees to cool down to? And then how about the weekends? Do you keep it at a set temperature all day and night? We are on the same time savings plan with APS as well.

      Angelica,
      On the weekends we set it all day at 75°F. We may move the temp around sometimes, but since there really isn’t a savings on weekends & holidays, we just wanted to be comfy!
      Great Question!

      Hi Angelica!

      Great question. We decided on 74°F and 80°F because it was recommended to us by a friend, and because it worked right away! No need to re-invent the wheel 🙂 On the weekends, we set it where are comfortable all day long. Since there isn’t “On Peak” times during the weekends or holidays, just set it where you are comfortable. Enjoy the cooler temps and more importantly the smaller bills!

    Hi Chris!

    I am always looking for ways to save money. We are on the same time savings plan with APS and utilize the Equalizer as well. I found your article interesting because we had always been told that it wasn’t a good idea to set the thermostat the way you are doing it. We have always had it set to 80 degrees to try and keep the cost down. After reading your article it makes sense to try it how you are doing it. Our home is single level, approx 2150 sq ft. How did you arrive at setting your thermostat at 74 degrees? Is that just your comfort level? My husband will be happy with the cooler temperature because he is always hot! Thanks for what you do!

      Hi Angelica! The 74°F – 80°F was a recommendation from a friend! It worked well right away and I’m a big believer in not having to re-invent the wheel 🙂 Give it a try and you should see a savings within the first few months! Thanks for the comment and tell your hubby I was always hot too 😉

    I love the idea of actually being comfortable in my house with using the setting you suggested. I started using this a few days ago and we all have enjoyed the cooler temps. I noticed in your article that between 12 and 7 the house should stay cool enough to only kick on once. My house is an 11 year old, two story, 1810 sq ft and I noticed that the house warms up and the A/C is starting up again at about 2 pm and continues to run about once to twice an hour. We have other energy reducing practices in place (suncreens, Thermal curtains, etc). I realy would like to know if you would have some additional advise or know someone who can answer my question as to why the house warms up so quickly and whether this is an option for me.

    I appreciate your help! 🙂

    Peach, we live in VA and its both hot and humid here on the coast. I called our utility co. and our peak hours during the summer are 11am-10pm. We usually get home from work about 6pm. If we tried to switch to a time usage plan, how would you manage the temperature change in the evening?

    Yes! This tip is the key to lower electricity bills here in Phoenix in the summer. I take it a bit further though, as we have the old 9 to 9 plan (cheaper off-peak rates than currently offered, not giving that up) and I keep my house at 83° during the day, 72° at night and 78° on the weekend.

    Thank you for the article! We have a two story house and 3 a/c units, one of which is upstairs in my husband’s office above the garage (where it gets very warm during the day). I am assuming you would suggest doing the same thing for all 3 units…. 80 degrees from 12 pm-7 pm and then down to 74 degrees from 7 pm – 12 noon?
    Thanks!

    Thanks for your post. I’ll have to try setting my thermostat at 80 from noon-7:00 PM and at 74 from then until noon. However, I would also recommend making sure the AC unit is in good working order. Things like changing the filters regularly, help the AC work more efficiently so it doesn’t have to be on as long.

      Sounds Good Ian! Also, make sure to contact your utility provider to find out exactly when the On Peak / Off Peak hours are for where you live. Noon – 7:00pm is what we have here in Phoenix, but it may be different where you are at 🙂

    Thank you Chris. Not only has your advise been very helpful, it’s the first time my family has actually been in control of our earnings. We particularly love the budget sheet, this seems to be working really well for us, and stopping a lot of arguments. But I also have to say I love your presentations and humour, we can relate so well to this and very easy to follow.
    Thanks heaps from Ros in Australia

    I am not sure if this type of strategy will work in the hot muggy Tennessee climate where I live. Sure it will save the money, but I think we will be terribly hot most if not all
    Of the time. We generally keep our thermostat set to 70 degrees year round whether heat or air. I could see those settings being comfy in AZ. because it’s a dryer heat and it get really cool as the some goes down. But again…I’m skeptical about it in the Deep South.

      Hi Abby,

      Thank-you for your comment! I 100% agree that Phoenix is a dry heat and you’re in muggy air which means the heat is actually much worse. With that said, try doing in on a 70°F – 76°F setting. The plan works NOT because of the actual temperature, but because you’re keeping your A/C from turning on and off 50 times per day. Also, I have others from the Deep South send me a few thank-you emails stating they saved money by tricking the thermostat like this 🙂 Good luck Abby!
